Replacing Fillings

Should I Replace My Fillings?

All dental fillings will need replacing eventually, and their longevity can be due to a variety of factors. The durability of your dental fillings will depend on the type of material used, the size and location of the filling, and your oral habits.

Amalgam Fillings

Amalgam has been used to fill teeth for decades, and these silver colored fillings typically last for 10 to 12 years. Eventually they can begin to crumble and leak, and are likely to fail much sooner if you have a particularly heavy bite.

Your general dentist in Sarasota will check the condition of these fillings at each appointment, and will recommend their replacement if there is evidence of further decay due to the filling leaking or crumbling.

Composite Resin Fillings

These fillings are made from tooth colored composite resin and will usually last between five and seven years. Composite resin is a popular material for fillings due to its virtual invisibility, but these fillings are more expensive as placement is very technique sensitive. Modern composite resins are quite durable and can withstand relatively heavy biting pressure. Over time these fillings can become stained. Your dentist will advise you when replacement is necessary.

Location and Size of the Filling

Fillings that are particularly large are more likely to fail. There is an increased risk that the tooth around the filling will fracture or break as it will have been weakened by the filling placement and the overall loss of tooth structure. Fillings in back teeth are more likely to fail as these come under much more pressure during chewing.

Oral Habits

Oral habits can affect the life span of fillings, including dental hygiene, nail biting and teeth grinding. A lack of dental hygiene will increase the risk of subsequent decay in that tooth, while other habits such as nail biting and tooth grinding can wear down teeth or cause them to chip or fracture. The best way to maintain your fillings is to have regular dental checkups and cleanings with your dentist in Sarasota.
