Ultimate Guide To Composite Resin (White Filling)If you’re like me, then you might not like the appearance of your teeth. I drink quite a lot of coffee and red wine, which stains my teeth. Years ago, I asked about getting them whitened; however they told me that some teeth (due to the density or some other factor) won’t respond to bleaching procedures. So bleaching was out for me too! Some people may be happy with the colouration of their own teeth – but some aren’t…

All of us love to have a beautiful smile. Having good and healthy-looking teeth helps us feel more confident about ourselves especially when we are amidst a crowd. However, if you are suffering from cavities or tooth decay, it can difficult for you to laugh, talk or smile more, reducing your self-esteem. A great solution to avoid feeling embarrassed or becoming self – conscious is to restore your decayed teeth with tooth-colored composite resin dental filling. To know more about this dental filling, take a look at this interesting guide listed below.

What is composite resin (White Filling)?

Composite resin is basically a dental filling material used for aesthetic dental restoration. A composite filling combines a tooth- colored plastic and glass mixture and is used for dental bonding front teeth or filling dental cavities. Formulated to resemble your natural tooth color, composite resins can be used on either back or front teeth. This type of dental filling can also for cosmetic purposes as it helps reshape disfigured teeth or change the color of the teeth, helping improve your smile. They are commonly used to restore front teeth in which the portions of the portions of dentin or enamel are teeth are chipped or broken. The filling is a great option for younger individuals involved in sports and is at a higher risk of injury. Composite resin fillings are also an ideal choice for those who want to have natural-looking filling.

How is a composite placed?

A composite filling is usually placed by a cosmetic or general dentist. The procedure of placing a composite resin filling is a little complicated when compared to that of an amalgam filling.


  • The dentist dries up the tooth by isolating it from saliva
  • An air abrasion or a drill is used to eliminate the infected part of the tooth
  • The dentists places the composite resin in layers over the opening
  • Each of the composite resin material is hardened by using a special light
  • After the tooth is filled with composite resin, it is shaped to resemble your natural tooth.

Although placing the composite resin filling can be quite time-consuming, most patients are quite pleased with the results.


#1: Versatility: A great advantage of using composite resin dental fillings is that is can be used to repair broken, chipped or worn out teeth apart from being used as a filling material for decay.

#2: Aesthetics: The color or shade of the composite fillings is closely matched to suit the color of the existing tooth. This type of dental filling is, therefore, a perfect option of dental filling for the visible parts of teeth or the front teeth.

#3: Tooth sparing preparation: When removing a tooth decay and preparing the tooth for a composite resin filling, lesser tooth structure is required to be removed when compared to a tooth that is prepared for an amalgam filling.

#4: Bonding to Tooth Structure: Chemically, composite filling bonds to the tooth structure more effectively that other types of dental fillings. This not only helps prevent breakage, but also helps protect the tooth from extreme temperature changes. As a result, using this filling helps strengthen your teeth.

#5: Does not contain mercury: The presence of mercury in dental fillings can often cause various health conditions, including high blood pressure, memory loss, and infertility among others. In addition, mercury used in fillings can also be harmful to pregnant women and unborn children. However, since composite resin filling does not contain mercury, opting for this type of dental filling is completely safe.


#1: Long procedure: The process of placing composite filling is quite time-consuming. The procedure can take nearly 15- 20 minutes longer time when compared to applying an amalgam filling.

#2: Lack of durability: Composite resin dental filling usually get worn out sooner than amalgam fillings. While amalgam fillings last for about 10- 15 years, composite fillings last for only five years. Additionally, when used for large cavities or are under the pressure chewing, composite fillings lack durability.

#3: Chipping: Depending on the location in which they are placed, composite materials can chip off the tooth.

#4: Frequent dental visits: If this type of dental filling is used for inlays, it may require you to visit the dental office more than once.

#5: Color Change: The shade of the composite often tends to change slightly if the patient drinks coffee, tea or other staining food.

Composite Resin vs. Amalgam: Why is composite resin filling preferred?

Helps preserve the existing tooth structure: When compared to an amalgam filling that requires a larger section of the tooth to be removed, a composite filling requires the dentist to remove only the deceased part of the tooth. This helps the dentist to protect the existing tooth structure of the patient.

Support Tooth Structure: Unlike amalgam fillings that can expand and contract with heat and cause the teeth to crack, composite filling supports tooth structure, shields your teeth from extreme temperatures and remains sturdy when used for small and medium dental fillings.

More Natural: While a composite resin filling is made to match your tooth and make your teeth, an amalgam filling is very obvious in the teeth. Instead of making your teeth pearly white, an amalgam filling can cause a grey tint to the teeth.

How much does a composite filling cost?

Having a composite resin dental filling done can be a costly affair. Generally, a composite filling can cost nearly up to two times more the price of amalgam fillings. However although most dental insurance plans cover the composite filling cost up to the cost of an amalgam filling, the patient may be required to pay the difference.

For decades, the composite resin has been advocated as a means to restore minor to moderate defects of teeth caused by trauma or decay. Using the filling helps preserve the healthy tooth structure as much as possible and preserve your natural tooth. One of the greatest advantages of this filling is that it helps make your decayed or worn out tooth look naturally healthy and well- maintained.However, consulting your dentist before opting for composite filling can be highly beneficial in helping you attain a bright and beautiful smile.


What is dental composite resin made of?

As with other composite materials, a dental composite typically consists of a resin-based oligomer matrix, such as a bisphenol A-glycidyl methacrylate (BISGMA), urethane dimethacrylate (UDMA) or semi-crystalline polyceram (PEX), and an inorganic filler such as silicon dioxide (silica).

What is resin composites?

resin, sometimes referred to as “plastic,” is used to transfer stress between the reinforcing fibers of a composite material. There are two major groups of resins – thermosets and thermoplastics – which are are made of polymers (large molecules made up of long chains of smaller molecules).

How long do resin composite fillings last?

Resin composite fillings last five to seven years, which is half the lifetime of an amalgam filling. Takes longer. The process of placing a resin filling is more involved, so it takes more of your time and the dentist’s.

Is composite resin strong?

Composite resin fillings are just as strong as amalgam fillings, but they look natural. In fact, you could have multiple fillings placed in your front teeth and no one would know whether or not you have natural teeth or ones with fillings. A cracked tooth can cause pain and be extremely susceptible to tooth decay

Is composite resin Safe?

In Conclusion, composite resin fillings are a safe option for restoring damaged teeth. But if you are concerned about BPA, you can talk to your dentist about using a BPA-free composite resin filling material that does not contain the conventional monomers such as Bis-GMA, HEMA, UDMA or TEGDMA

Which dental filling is the safest?

Amalgam fillings are safe. A great deal of research has examined these fillings and found them to be an effective, long-lasting treatment for dental decay. Amalgam, or silver, fillings are made with mercury, silver, tin and copper

Can composite fillings last 20 years?

On average, composite fillings tend to last 5 to 10 years, while amalgam fillings last from 10 to 15 years. Meanwhile, well-installed ceramic fillings can last up to 20 years or so in a patient’s mouth, which is certainly a blessing in numerous ways!

Which tooth filling is best?

Composite fillings are the most widely used dental filling material. They’re made of glass or quartz in resin. Your dentist may choose a composite filling if the size of your cavity is small to medium, or if your tooth gets a lot of chewing action

Advantages of Composite Resin over other filling materials

As a dental enthusiast, I have an extensive understanding of different materials used for dental filling. One of the best materials ever introduced in the dentistry world is composite resin, which has become increasingly popular over the years. Made from a mixture of plastic and finely ground glass-like particles, composite resin is designed to match the color of your natural teeth, making it an excellent alternative to silver amalgam fillings.

One of the most significant advantages of composite resin over other filling materials is that it is considered aesthetically pleasing. Who wouldn’t want to maintain a perfect smile after a dental procedure? Since the material can be made to match the color of the natural teeth, it is often used in areas of the mouth where aesthetics are critical. In the past, brittle and translucent materials like ceramic were used, but they didn’t last long; composite resin is considered more durable and has more flexibility, making it ideal for dental restorations.

Another advantage of composite resin is that it bonds well to the tooth surface; this means there’s no need for undercuts that may cause tooth sensitivity, making it easier and more comfortable for fillings to be done. This bond allows for the preservation of more of the natural tooth, as less drilling is required to fasten the filling securely. With composite resin, cavities can be removed effectively, and tooth structure weaknesses can be restored with minimal drilling.

In conclusion, composite resin is an excellent dental filling material due to its aesthetic appeal, durability, and bonding ability. It has become a popular option for people seeking a less invasive treatment with long-lasting results. While it may not be perfect for every dental issue, an experienced dentist may suggest it as the best option for you. Therefore, it is crucial to consult with a reputable dental professional to assess your needs and provide the appropriate treatment plan for you.

Color and Shade Matching: How to choose the perfect composite resin for each patient

A crucial aspect of restorative dentistry is providing patients with crowns, fillings, and veneers that match the color and shade of their natural teeth. A composite resin plays a vital role in achieving this goal. This resin is a tooth-colored material that is used to fill cavities, rebuild fractured teeth, and erase discolorations. However, not all composite resins are created equal, and it’s essential to choose the right one for each patient.

When selecting composite resin, several factors come into play. One of the most important is the color and shade of the patient’s teeth. Dentists need to take into consideration the hue, value, and chroma of the natural teeth to create a restoration that matches it perfectly. They will also evaluate the translucency of the enamel, which determines the amount of light that passes through it. The right composite resin can mimic this quality, creating a seamless and natural result.

Another factor to consider is the location of the tooth. For instance, the incisors require a composite resin that mimics the translucency of natural teeth, while the molars need a resin that can withstand the pressure of chewing. Additionally, dentists may need to adjust the color of the composite resin to match the surrounding teeth, or the shape to recreate the natural contour of the tooth.

To sum up, color and shade matching is a crucial aspect of restorative dentistry. Choosing the right composite resin for each patient is a vital part of this process. From evaluating the color and translucency of the natural teeth to considering the location of the tooth, there are several factors to consider before deciding on the perfect composite resin. Ultimately, the goal is to provide patients with a beautiful, long-lasting restoration that matches their natural teeth seamlessly.

Composite Resin Bonding Techniques and Adhesives

Composite resin bonding techniques and adhesives are essential in modern dentistry. Composites are tooth-colored materials that can restore damaged, decayed, or discolored teeth to their natural appearance. The adhesive techniques used to bond these composites have significantly evolved over the years, and dental practitioners continue to perfect this procedure.

Composites are most commonly used in cosmetic dentistry to improve the appearance of teeth. Bonding techniques allow dentists to apply composites to teeth, restoring them to their natural appearance, shape, and size. Additionally, the bonding techniques used in conjunction with composites allow for better retention, durability, and longevity of the restored teeth.

There are various types of composite resin bonding techniques, each with its own set of criteria. The most common method is the direct technique, which involves placing a composite resin directly onto the tooth surface. The indirect technique involves fabricating the restoration outside of the mouth and then bonding it to the tooth.

Adhesives play a crucial role in the process of bonding resin composites to teeth. They can be classified into two broad categories: etch-and-rinse adhesives and self-etch adhesives. Etch-and-rinse adhesives use an acidic solution to prepare the tooth surface for bonding, while self-etch adhesives contain acidic monomers that simultaneously etch and prime the tooth surface.

In conclusion, composite resin bonding techniques and adhesives have revolutionized modern dentistry. These techniques allow for the restoration of damaged teeth to their natural state with little to no visible difference, providing patients with a more aesthetically pleasing smile. With the ongoing evolution of these techniques, dentists can continue to provide their patients with the best possible treatment, resulting in healthier, more vibrant teeth.
