The real question is how do you get rid of a bubble in your mouth WITHOUT getting rid of your mouth and having to eat and talk through a straw?

Some people, like myself, get bubbles stuck in their mouth from time-to-time. This is usually due to saliva buildup or even air bubbles caused by soda fizz or bursting food. If it’s one of those small harmless bubbles that will eventually go away on its own (which happens to me quite often), I just wait it out. However, if the bubble gets caught between my teeth and won’t budge, then I know it’s time for some assistance.

What are these blisters?

When irritation or small injuries in the oral mucosa, an immune reaction occurs. In many cases, pus or an oral fistula forms to drain it.

blister in mouth causes

  • This causes the blister to swell and usually a thin film of pus covers it. Painful, these are usually as well.
  • Many diseases are characterized by blisters in the mouth. Mostly they are harmless, but before starting therapy, the cause should be determined.

Note: Do not be afraid of the doctor! This guide provides only information, but not a proper diagnosis. That is exactly why you should rather see a doctor in case of doubt to clarify the exact cause.

Tip to save yourself expensive treatments at the dentist:

Philips Sonicare DiamondClean. This toothbrush cleans teeth very thoroughly from plaque & brings a bright smile. If you want to invest in your dental health & save yourself unpleasant visits to the dentist, then I can only recommend the sonic toothbrush.

With the Oral-B Genius or the Pulsonic Slim, there are also alternatives from other manufacturers.

Best start today to consistently prevent & oral diseases as well as cavities in the tooth.


In most cases, the blister is a so-called aphthae.

In this case, there is a local painful change in the mucous membrane of the mouth or swelling of the gums.

gums swollen

Mouth swellings from aphthae can occur throughout the mouth.

In addition to the oral cavity, however, aphthae & blisters can also occur on the tongue, under the tongue, on the lips, or on the tonsils.

  • Aphthae occur in different sizes: A distinction is made between minor and major aphthae (small and large, respectively).
  • Small aphthae have a diameter of less than 1 cm, while vesicles larger than 1 cm are called major aphthae.

Who has ever had an aphte, will not be badly surprised if soon after another blister appears in the mouth.

Because aphthae are recurrent, your dentist will then speak of chronic recurrent aphtosis.

Causes of apthae

The exact cause is unfortunately not yet fully researched, however, medical experts assume that immune deficiency is a significant part of it.

Folic acid and B12 deficiency can also promote aphthae formation.

  • Women are more commonly affected than men.
  • Other influencing factors: genetic, psychological, hormonal, celiac disease (gluten intolerance)

Don’t worry, if your partner has an aphthae in the mouth, you can still kiss. There is no risk of infection.

Symptoms of aphthae

Aphthae usually appear suddenly with very severe pain. The pain is often accompanied by an itching or burning sensation.

Also, a white layer forms on the blister.

blister in mouth symptoms

Aphthouses often cause a lot of pain.

Eating and drinking – but also brushing your teeth yourself with „gentle“ Oral-B toothbrushes or ultrasonic toothbrushes – worsens the symptoms, sometimes the pain is even so great that sufferers eat much less than normal and lose weight as a result.

  • The pain does not depend on the size of the blister, but on the affected area. Aphtae on the tongue are the most painful.
  • Just as quickly as the pain occurred, it usually subsides. This usually takes 2-5 days for minor aphthae.

Minor aphthae also usually do not leave a scar, but disappear without residue.

Overview: disease progression of aphthae

Prodromal stage24 hTingling, feeling of tightnessPreculent stage18 – 72 htaking pain

Ulcerative stage 1 – 16 days decreasing pain
healing phase 4 days – 1 month pain-free


A complete cure for chronic aphtosis is unfortunately not possible to date.

Therapy is therefore limited to symptomatic relief of the pain.

  • For isolated blisters, external (topical) mouth gels are usually prescribed.
  • The lidocaine contained in them has an analgesic effect and other substances have an antibacterial and anti-inflammatory effect.

Cortisone sprays provide an immediate effect, but because of the side effects are prescribed only in very severe pain.

If aphids occur frequently at a short interval, your doctor may advise cortisone therapy for several months.

Propolis has also been shown to be very effective. It is purely herbal and can be purchased over the counter.

Home remedy for aphthae

Chamomile and green teas have a soothing effect on the mucous membrane.

Tea tree oil is also suitable. Apply it locally to the affected area with the help of a cotton swab. After a few days, the blister will dry up.

  • Chew papaya pieces: This fruit contains an enzyme that becomes anti-inflammatory. This will speed up the healing process. : Apply the packing powder with a moistened cotton swab. Locally, it has an anti-inflammatory and analgesic effect.

Take vitamin C daily. This strengthens the immune system and promotes the healing process.

Also drinking aloe vera juice has proven effective in the treatment of aphthae.


As with most oral conditions, good oral hygiene has also been shown to be a good preventative measure for aphthae.

Regular tooth brushing (preferably with an electric toothbrush such as the Oral-B Pro 6000, Philips Sonicare Flexcare Platinum, or Oral-B Triumph 5000) after each meal noticeably lowered the incidence of vesicles.

  • Also, abstaining from sweets showed that aphthae were no longer as frequent.
  • A weakened immune system promotes the development of the blisters. Make sure you get enough sleep and avoid stress.
  • A balanced diet and adequate exercise strengthens the immune system and prevents the formation of aphids.

In baking, instead of sugar, better rely on substitutes such as birch sugar (xylitol), so as not to provide a food base for harmful bacteria.

Herpes in the mouth

There are different types of the herpes virus.

Herpes simplex type 1 causes blisters in the mouth, among other things. Infection with this virus is also called oral thrush.

  • The clinical picture is very similar to that of aphthae. Most often, children aged 10 months – 3 years are affected.
  • Herpes can not be cured and breaks out again and again throughout life. Once the immune system is weakened, blisters appear on or in the mouth.

Most often the blisters appear as a side effect of a cold or flu, be very careful here when brushing with a toothbrush for children.

blister in mouth herpes

Mouth blisters from herpes are especially common in children who are newly infected with the virus


Mouth sores are caused by the herpes simplex type 1 virus.

The virus can be transmitted by what is called droplet infection. So you can easily become infected if you kiss someone who has the disease or use the same cutlery.

The risk of infection is very high.

  • Because the virus can be transmitted very easily, almost everyone has it inside them.
  • But in most it comes throughout life to no symptoms.

But even with no symptoms, the infected person can infect others.

Be especially careful if it is just an acute phase of oral thrush have. Then the risk of infection is much greater.

Symptoms (besides a blister in the mouth)

Once the immune system is weakened, the course of the disease begins initially with fever. This lasts for about 3-5 days.

  • From day 3, the gums swell and slowly a blister forms. The blister looks very similar to the aphthae.
  • Sometimes small white spots also form on the palate, tongue and lips at the same time. Then the virus has spread.

To severe pain usually occurs before the blisters. Children are then often very whiny and refuse food and drink. As a result, they lose weight.

  • As the disease progresses, widespread inflammation of the gums occurs, causing them to appear blood red. Bleeding gums may also occur.
  • The lymph nodes in the neck swell due to the immune reaction and saliva production increases. In addition, there is a strong acidic halitosis.

Speech is difficult, as any movement of the tongue causes incredible pain.

bubble in mouth risk groups

Children & teenagers are among the risk group. Once spread, the herpes virus remains in the body for life.

The course of the disease is much more dramatic in children than in adults. The acute phase can drag on for several weeks. After that, the blisters heal, and may leave a small scar.

How is oral thrush diagnosed?

Only a laboratory test can tell if you are carrying the herpes virus. Your doctor will draw your blood and then test it in the lab for HSV 1 antigens. If these are positive, you are carrying the pathogen.

Therapy options for HSV 1 disease

Unfortunately, there is still no way to definitively eliminate the virus.

Lidocaine can be sprayed locally on the inflamed mucosa.

Sometimes antiviral medications are given, but this must be felt necessary by your doctor.

herpes cure

Because not everyone is suitable for it. The antivirals help speed healing, but do not actively fight the pathogen.

Must special attention be paid to children?

With sick children, it is extremely important to ensure adequate food and fluid intake

Quickly, little ones can become dehydrated as they try to avoid the pain.

Fluid food is recommended, as children do not have to chew and the pain is easier to bear.

Can I prevent mouth sores in any way?

The be-all and end-all: avoid sick people who are going through an active phase. No kissing, close physical contact, or anything like that.

  • Do not share your cutlery.
  • If you are breastfeeding, clean your nipple thoroughly beforehand.

Attention to good oral hygiene, especially dental care for babies.

A strong immune system ensures that the virus does not break out. Exercise regularly and make sure you eat a healthy diet.

Do you suspect you may have HSV 1? Consult a doctor immediately. The earlier the disease is detected, the better the prognosis.

Varicella infections

Varicella is a special form of the herpes virus (varicella zoster virus) causes chickenpox.

This disease most commonly occurs in childhood and is characterized by fluid-filled blisters all over the body.

While the viruses remain in the bloodstream after the disease is overcome, usually the affected person is immune for life and the disease does not break out again.

And of course, you can also familiarize yourself with general dental care tips related to healthy teeth.

You see: There are many causes of blisters in the mouth. So if in doubt, better visit your (dental) doctor.

Reactivation of the virus

When chickenpox clears up, the virus remains latent in our bodies.

  • As mentioned earlier, the virus usually does not break out again. However, an immunocompromised body offers exceptions:
  • Then it may come to the blisters in the mouth reappear or it comes to a more advanced form of chickenpox.

Then one speaks of shingles.


Typically, the disease breaks out during cold seasons.

  • In addition to fever- headache and pain in the limbs, small blisters called exanthema form all over the body.
  • These are filled with fluid and itch like hell. If you scratch, the blisters burst open easily and the liquid comes out.

The fluid is filled with the virus cells. Usually then scars remain.

Bubbles also form in the mouth, which can even be purulent. They affect the tonsils, throat, tongue, and palate.

How is varicella transmitted?

Varicella is transmitted very easily.

  • The viruses survive for some time in the air and if you are in the same room with an infected person, this is already enough to become infected with the virus. One speaks then of a droplet infection.
  • Through this easy and fast transmission route, it is not surprising that almost everyone up to the age of 25 years has already had chickenpox.

The fluid in the vesicles is highly contagious. The germs contained therein can also lead to infection. Quickly you have germs on your finger and inhale them unintentionally.

During pregnancy, transmission to the unborn child is also possible, but not as likely.

Special care should be taken with pregnant women

While infection of the child is relatively unlikely, malformations and genetic diseases may occur if infection occurs during the 8th-21st week of pregnancy.

  • Defects of the central nervous system, skeletal deformities, and eye malformations then occur in clusters.
  • During pregnancy, the unborn child can be infected with the viruses through the mother’s placenta.

If infection occurs, the consequences are devastating.

Since the baby itself does not yet have a sufficient immune system and the mother can not yet transfer the antibodies in high numbers, there is great damage.

The central nervous system in particular is susceptible.

Progression of varicella

When the virus enters our bodies, it takes about 8-21 days before it breaks out.

After outbreak, the duration of the disease amounts to 2 weeks in children, and may be significantly prolonged in adults.

  • After 1 to 2 weeks, the fluid in the vesicles disappears and a crust forms.
  • It is very important not to remove the crust. Because this will not only leave scars, but the crusts can also become inflamed.

If you scratch away the crusts, a fine crack forms on the skin surface. Other germs then have an easy time getting into the body.

Severe skin rashes and other symptoms are the result. In the worst case, even blood poisoning can occur.


Because it is a viral disease, only the symptoms are treated to the greatest extent possible.

  • Your doctor will prescribe an antipruritic lotion to apply to the chickenpox several times a day.
  • If you have an existing fever, you can take either ibuprofen or acetaminophen.

Aspirin is not advised, because children can develop the so-called Reyes syndrome due to the existing viral disease.

vesicles in mouth

Reyes syndrome causes cellular dysfunction, particularly in the brain and liver, and can be fatal.

Adults, especially the immunocompromised, should take antivirals such as aciclovir.

For scratched and inflamed blisters, topical antibiotic cream will help.

There are additional things you can do to speed up the healing process

Wear loose and airy clothing. On the one hand, the itching will not be aggravated, and on the other hand, the oxygen will help to support the healing.

Cold compresses help to suppress the itching.

  • Rest and stay away from communities. This can help contain the risk of infection.
  • Make sure, especially with children, that the little ones temporarily do not attend school or kindergarten.

If chickenpox is suspected, a doctor should always be consulted.

Prevent varicella through vaccination

The vaccine consists of live varicella, but it is injected into the body in an attenuated form.


This allows the body to make antibodies, and the virus does not break out.

  • The vaccination consists of 2 shots, given about 4-6 weeks apart.
  • From the 12th month, the vaccination can also be given to infants, but is not mandatory.

The vaccination is not recommended for children, but rather for adults who have never had chickenpox before. Since the course of the disease is then more severe, many can be immunized.

For whom is the vaccination not suitable?

In particular, people with weakened immune systems are advised against getting vaccinated. Also with existing high fever should be refrained from it.

If you are pregnant, your doctor will not vaccinate you because it is possible to transmit the disease to the baby through the placenta.

Bubbles in the mouth caused by salivary stones

Salivary stones are made of calcium phosphate. In most cases, there is no discomfort.

  • However, when the stones block the salivary gland, inflammatory processes occur in the mouth.
  • This causes, among other things, blisters to form around the salivary gland.

Because saliva cannot drain properly, it triggers an immune cascade.

Causes of salivary stones

The exact cause has not yet been determined. Researchers suspect that an altered saliva consistency leads to it.

  • Diseases such as diabetes mellitus, cystic fibrosis and gout can result in salivary stones
  • But also an excess of calcium leads to the formation of stones. Then one speaks of hypercalcemia.

Various viruses cause the salivary glands to swell and the salivary outflow is disturbed. These include mumps, cytomegaly and coxsackie A virus.


Inflammation occurs suddenly and usually on one side only. Pain occurs mainly during chewing.

  • The lymph nodes in the neck are swollen and painful.
  • Ingestion of food increases pain because more saliva is produced.

Fever is usually an accompanying symptom and visible redness on the skin in the area of the affected gland occurs.

  1. Red painful vesicles appear in the area of the inflamed gland.
  2. Pus forms inside the glands and sometimes empties into the mouth.

This results in a very sour taste.

Complications can be abscesses to blood poisoning.

How does the doctor diagnose salivary stones?

With the help of the typical symptoms (especially pain that occurs when chewing), the doctor already has a suspicion.

vesicles in mouth diagnosis

If he palpates the salivary gland, it empties and pus leaks into the mouth.

  • The pus is sent to the laboratory to rule out bacterial infection. Additional blood tests are performed.
  • By ultrasound examination, salivary stones can be found from a size of 8 mm.

Additional diagnostic tools such as CT, MRI, or an endoscopy may be consulted to provide a definitive diagnosis.

Treatment of salivary stones

Generally, the focus of treatment is on stimulating the salivary gland. Through so-called salivary glands, more saliva than usual is produced

medication salivary stone

  • Gum, candy, and special drinks are popular salivary lollipops.
  • The resulting increase in saliva flow cleanses the gland and stones can drain away.

In addition, anti-inflammatory medications and antibiotics are prescribed for possible bacterial colonies.

Your doctor will also try targeted massage to flush out the stone.

Ultrasonic waves can also be used to break up the calculi, and drainage is then facilitated.

If the above remedies do not help, the stone must be operated out to avoid complications.

What you can do at home

As well as your doctor, you can try to bring up the stone by massaging it specifically.

chewing gum for salivary stones

Chew sugar-free dental gum to increase saliva flow

How can salivary stones be prevented?

Good oral hygiene and regular brushing with brushes such as the Oral-B Smart 6000, Philips Sonicare Flexcare Platinum, or Oral-B Pro 600 can help reduce the occurrence of salivary stones.

Chew gum or suck candy. Increased saliva flow will help keep the salivary glands flushed regularly, which will help keep them clean.

Fig Warts

Fig warts are sexually transmitted and occur mainly in the genital area.

However, these benign growths can also occur in the mouth. They can be identified as small blisters.

How are genital warts transmitted?

Most importantly, papillomaviruses are transmitted quickly through unprotected sexual intercourse with an infected person.

  • But the viruses can also penetrate small, barely visible skin lesions and affect the organism.
  • Preexisting skin diseases or a weakened immune system favor the outbreak of genital warts.

Babies can be infected at birth by their mothers.

How do genital warts develop?

First of all, the viruses remain asymptomatic in our body. However, favoring factors trigger the outbreak of the disease.

bubble in mouth smoker

Smoking, alcohol, or immune deficiencies make an outbreak more likely.

Chronic diseases such as diabetes mellitus are risk factors.

  • The consumption of nicotine (smoking also damages teeth) and alcohol promotes the growth of warts.
  • The long-standing use of the anti-baby pill has also emerged as a favoring factor.

A weakened immune system is not properly able to contain the growth of viruses and they spread throughout the body.

Uncontrolled growths of the skin are the result and the warts form.

Symptoms of genital warts

Symptoms vary and depend on exactly where the warts occur.

In the genital area, they are barely visible and do not cause any pain. Therefore, they often go undetected.

  • If the warts occur internally, for example in the anus or vagina, itching, burning during urination and bleeding may occur.
  • In women, there is also increased discharge. A protective function of the body to fight the pathogens.

Most often, genital warts are pinhead-sized and skin-colored.

But there may also be increased growth and color changes. For example, a flower-head-like shape may form that can be red, black, or grayish in color.

How are genital warts diagnosed?

If you suspect you have genital warts, see a doctor immediately.

mouthbladder doctor

The conversation in the doctor’s office is uncomfortable, but necessary.

The medical professional will look at the warts first before ordering further tests.

  • By taking a swab, the laboratory can determine if the papillomavirus is present. A blood analysis is also possible.
  • It is extremely important to consult a doctor because the risk of infection is very high. Even a touch with the finger is enough to transmit the virus.

Should you be diagnosed with the papillomavirus, it is important to treat your partner with.

Treatment of genital warts

Special creams exist that are applied to the affected area. These stimulate the immune system so that the body can fight the viruses on its own.

  • There is also the possibility of destroying the warts with the help of cold sprays or special etching agents.
  • Operatively, they can also be easily removed. Here they are simply cut out under local anesthesia.

medication genital warts

In 30% of cases, the warts heal spontaneously, without any treatment.

Increased risk for sufferers

The viruses can always break out when the immune system is weakened.

In addition, it has been proven that the papilloma viruses can also lead to cervical cancer.

This is why it is advisable for women to have a checkup by their gynecologist every six months.


Unfortunately, successful therapy does not guarantee that the disease will not break out again. A small immune deficiency is already enough and the warts are back.

In 25%-65%, the warts reappear within 6 months after successful therapy. Especially with surgically removed growths, the risk is increased.

Prophylaxis for genital warts

Make sure to use condoms for contraception during sexual intercourse. Especially if you have frequently changing partners.

People who have not yet had sexual intercourse can get vaccinated against HPV.

More blisters in the mouth

There are, of course, other types of blisters. To diagnose the exact causes, you should always see a doctor

Red blisters in the mouth

The mostly blood-filled red blisters in the mouth occur quite frequently. They occur when you bite your tongue, for example. Although they hurt like hell, they subside on their own after a few days.

Black blisters in the mouth

Occasionally, black, sesame seed-sized blisters appear on the lining of the mouth. They are so small that they are barely visible.

Unfortunately, the cause is still unclear, but the blisters disappear just as quickly as they appeared.

Conclusion & Tips for prophylaxis

You can never completely rule out blisters in your mouth, even with the best dental care.

Dental care for gums

However, the more thoroughly you brush your teeth & take care of your body, the more likely your immune system will be able to deal with viruses as well as bacteria that can cause mouth blisters.

Recommended models include the Philips Sonicare DiamondClean or the Oral-B Pro 5000.
