What is a Composite Resin (White Dental Filling)?
A composite tooth filling is a tooth-colored restoration made of plastic and glass particles used to repair decayed teeth. Because this type of tooth filling blends in with your natural teeth, many patients prefer this option. Composite resin fillings are used for cosmetic enhancements of the smile by altering the color of the teeth or reshaping disfigured teeth. Click here to book a dental appointment.
How is a composite dental filling placed?
Our dentist isolates the tooth from saliva to keep it dry, then the infected part of the tooth is removed. Next, the dentist places the composite in layers, using a special light to harden each layer. Finally, the dentist will shape the composite to fit the tooth and then polish the composite to inhibit staining and early wear.
Advantages of composite dental filling
Aesthetics are the main benefit of composite resin fillings considering you can blend shades to create a color that matches your teeth. Also, less tooth has to be removed to place the composite filling.
What are the disadvantages?
A patient may experience postoperative sensitivity. Additionally, the color of the composite can change somewhat if the patient drinks tea, coffee or other staining foods. You do have options to prevent discoloring. Your dentist can set a clear plastic coating over the filling to prevent the colour from changing.
Dental Amalgams (Silver Dental Fillings):
Dental amalgam, commonly known as silver fillings, remains one of the most widely used filling materials in Canada due to its effectiveness and cost-efficiency. These fillings are primarily composed of a mixture of mercury, silver, copper, and tin, giving them a distinctive silver appearance. Which is why they are typically used for back teeth, where aesthetics are less of a concern. Click here to book a dental appointment.
Advantages of Dental Amalgams:
Cost-Effective: Amalgam fillings are generally less expensive than other types of fillings, making them an accessible option for many patients.
Durability: They are known for their strength and longevity, often lasting 10-15 years or more, longer than other filling materials. This durability makes them ideal for areas of the mouth that experience significant chewing forces.
Ease of Application: Amalgam fillings can be placed in a single dental visit. The material hardens quickly, allowing for immediate chewing on the repaired tooth.
Resistance to Wear: These fillings wear down less over time compared to some composite fillings.
Disadvantages of Dental Amalgams:
Aesthetics: The silver color of amalgam fillings can be a disadvantage for those who prefer a more natural look.
Mercury Content: Although amalgam fillings contain mercury, numerous scientific studies, including those by the World Health Organization and the FDA, have concluded that the amount of mercury released is minimal and does not pose a health risk to the general population. However, for certain groups like pregnant women, children, or those with kidney issues, some dentists might recommend alternative materials as a precaution.
Expansion and Contraction: Amalgam fillings can expand and contract slightly with temperature changes in the mouth, and may crack.
Allergic Reactions: Though rare, some individuals might have an allergic reaction to the metals in amalgam fillings.
When considering dental amalgams, it’s important to discuss with your dentist to weigh these factors against your specific dental needs, aesthetic preferences, and any health concerns you might have.
