What causes cavities?
Cavities are caused when bacteria in our mouths mix together with sugars from the food we eat to form an acid that eats away at a tooth’s enamel. While cavities are often associated with children eating candy, adults can and do also get cavities too. If you have had fillings before, the edges of them can be a prime location for recurrent cavities. Part of the reason for practicing good dental hygiene including brushing, flossing, and regular dental visits is to prevent cavities.
How are cavities treated?
Cavities are usually treated with a filling. The silver fillings most people associate with the word are known as dental amalgam fillings. They are the cheapest, most common type of filling and are often a mixture of metals such as silver, copper and tin. This type of filling is mostly used on molars because of their unnatural look. For a more aesthetic and natural look, composite or porcelain materials may be used. In either case, the fillings are done directly and should only involve one visit to the dentist. Your dentist may give you a small local anesthetic to “freeze” the area before clearing out any decay within the tooth, shaping the hole, and filling it. Depending on the material used, your dentist may “cure” the filling with a special light to harden it before sending you on your way.
How do I care for a filling?
Fillings are cared for just as you would your normal teeth: by brushing and flossing and visiting your dentist regularly. Your dentist will routinely check to make sure any fillings you may have are not loose, broken or needing replacement.
