When treating a cavity, the dentist will remove the decayed portion of your tooth and fill it with another substance. This procedure is called a filling. There are multiple options for the material to be used in the filling, the most common of which are composite fillings and amalgam fillings. A composite filling is also known as a tooth colored filling, since the material used in the filling can be closely matched to the color of your teeth.
Composite fillings provide good durability for small to medium cavities, and the procedure typically involves removing less of a tooth than you would during an amalgam filling. They are also particularly well suited for treating front or highly visible teeth because of their natural look. Composite fillings can be used for decayed tooth (i.e. cavity), chipped or broken teeth, hence decreasing the gap between teeth.
How its done?
After the dentist numbs the area where the filling is to be placed, he will remove any decayed portions. A substance is then applied to help open up the pores of your teeth for a stronger bond, and hardened and cured with a special light. Once this is complete, the filling is applied in thin layers to slowly form the complete filling. After the composite has hardened, the filling will be smoothened and polished to be comfortable and fit your bite.
Composite fillings, also known as resin-based fillings, offer a range of benefits that make them a popular choice for dental restorations. One of the most significant advantages is their aesthetic appeal. Composite fillings can be precisely matched to the natural color of the patient's teeth, making them virtually indistinguishable from the tooth's original structure. This is particularly important for fillings in visible areas, such as the front teeth, where a natural appearance is crucial. The ability to blend seamlessly with the surrounding tooth material helps in maintaining the patient's smile and confidence. Additionally, composite materials can be sculpted to replicate the natural contours and grooves of the tooth, further enhancing their realistic appearance. This makes composite fillings an excellent choice for patients who are concerned about the cosmetic implications of dental work.

Another major benefit of composite fillings is their bonding capability. Composite materials adhere directly to the tooth structure, providing a strong and durable bond. This bond not only helps to support the remaining tooth structure, reducing the risk of breakage and further decay, but also allows for more conservative tooth preparation. Unlike amalgam fillings, which often require the removal of healthy tooth material to create a stable cavity for the filling, composites can be applied in thinner layers, preserving more of the natural tooth. This minimally invasive approach contributes to the overall strength and longevity of the tooth. Moreover, the composite material's ability to bond with the tooth also helps to seal the cavity, preventing bacteria from entering and reducing the risk of recurrent decay. Over time, this can lead to better long-term oral health outcomes and fewer dental interventions. In summary, composite fillings offer both aesthetic and functional advantages, making them a superior choice for many dental patients.
Composite fillings, also known as tooth-colored fillings, are made from a blend of synthetic resin and finely ground glass particles. The main components include a matrix of bisphenol A-glycidyl methacrylate (Bis-GMA) or urethane dimethacrylate (UDMA) resins, which provide the material's pliable structure. This resin matrix is mixed with filler particles such as silica, quartz, or glass, which enhance the filling’s strength, durability, and wear resistance.
Additionally, composite fillings contain coupling agents like silane, which chemically bond the resin matrix to the filler particles, ensuring a stable and cohesive structure. The blend also includes initiators and accelerators that enable the material to harden or "cure" when exposed to a specific light wavelength during the dental procedure.
Pigments are added to the composite mixture to match the color of the patient’s natural teeth, allowing for a seamless and aesthetically pleasing restoration.
Composite fillings are popular for their ability to bond directly to the tooth structure, providing a strong and durable repair that preserves more of the natural tooth compared to amalgam fillings. They are versatile, suitable for both front and back teeth, and can be used to fix cavities, chipped teeth, and other cosmetic dental concerns.
The removal of amalgam fillings requires careful technique to ensure patient safety and minimize exposure to mercury. The procedure typically begins with the dentist administering local anesthesia to numb the area around the tooth with the amalgam filling. This ensures patient comfort throughout the process.
Next, the dentist uses a dental dam, a rubber sheet that isolates the tooth from the rest of the mouth. This helps prevent any amalgam particles or mercury vapor from being ingested or inhaled. The dentist may also use high-volume suction and a specialized filtration system to capture mercury vapor and particles.
Using a high-speed dental drill, the dentist carefully cuts the amalgam filling into smaller pieces, which can then be gently removed. This method reduces the amount of heat and friction generated, minimizing the release of mercury vapor. Throughout the procedure, continuous water spray is used to keep the tooth cool and to help flush out debris.
Once the amalgam filling is removed, the dentist thoroughly cleans the cavity to remove any remaining filling material and decay. A new filling material, such as composite resin, is then used to restore the tooth. The dentist ensures proper fit and bite alignment before polishing the filling for a smooth finish. This meticulous process ensures the safe and effective removal of amalgam fillings, protecting both the patient and dental staff from mercury exposure.
If you're considering cosmetic fillings, the first step is to schedule a consultation with your dentist to discuss your goals and options. During this appointment, your dentist will evaluate your dental health, examine the teeth needing fillings, and determine if cosmetic fillings, such as composite resin fillings, are suitable for you.
Once you've decided to proceed with cosmetic fillings, your dentist will begin by thoroughly cleaning the affected teeth to remove any decay or old filling material. The tooth will be isolated using a dental dam to keep the area dry and free from saliva.
The next step involves preparing the tooth for the filling. The dentist will shape the cavity to ensure a proper fit for the filling material. Composite resin, the most common material for cosmetic fillings, is selected for its ability to match the color of your natural teeth.
The composite resin is then applied in layers, with each layer being hardened using a special curing light. This process ensures a strong bond and a natural appearance. Once all layers are applied and cured, the dentist shapes and polishes the filling to match the contours of your natural teeth, ensuring a smooth and comfortable fit.
Finally, your dentist will check your bite to ensure the filling aligns properly with your opposing teeth. Following the procedure, maintain good oral hygiene and attend regular dental check-ups to keep your cosmetic fillings in optimal condition.
