Fillings & Restorations
A dental restoration uses a dental restorative material to restore the function, integrity, and morphology of missing tooth structure. The structural loss is typically the result of decay or trauma. At Today’s Dentistry, Dr. Brennan has over 30 years of experience helping patients restore their teeth to a fully-functioning and natural looking state.

A composite filling, typically made from ceramic (ground glass) and resin, offers a few advantages over silver fillings. For one it can be shaded to match the color of a person’s existing teeth. Composite fillings chemically and physically bond to tooth enamel to create a tight, reinforced seal with the natural tooth. Sometimes less tooth structure needs to be removed compared to amalgam fillings when removing decay and preparing for the fillings. As more people want natural looking smiles, composite fillings have become increasingly popular.
Dental amalgam is a commonly used filling material that has been in use for over 150 years. It is a mixture of mercury, silver, and at least one other metal. Dental amalgam has many advantages over other restorative material such as low cost, durability, strength, and ease of placement. Silver fillings contain 50% mercury. They can corrode, leak, and cause stains on your teeth and gums. Amalgam possesses greater longevity than other direct restorative materials, such as composite. On average most amalgam restorations serve 10 to 12 years, where as resin based composites serve a bit more than half that time. However, with recent improvements in composite material science and a better understanding of the technique-sensitivity of placement, this difference is decreasing rapidly.
The American Dental Association Council on Scientific Affairs has concluded that both amalgam and composite materials are considered safe and effective for tooth restoration.
