They have been used in Japan and Western Europe since the 1980s, but were not approved for use in the United States until 1998 due to the Food and Drug Administration's (FDA) concerns about virus contamination.

Is it common to get a cavity after dental sealants have been applied?

A sealant was done on a tooth of mine and not 2 years later did a first cavity apear. Although sealants help protect for the future, they will not always work. Its deffinitly a good idea to have it done but like condoms theres always that 6% chance that it will escape.AnswerIt is possible that the sealant fell off the tooth. There is no guarantee that a sealant will stay in place, especially if you eat hard foods (like hard candy or corn nuts) and the typical life span for sealants, even whey they are correctly placed by trained professionals, is about 6 years. Then there is the idea of taking proper care of your mouth at home and taking control of your diet and watching the types of junk you put into your mouth. How often did/do you brush? do you do it correctly? Do you use dental floss? Correctly? Please don't be so ready to complain to a dentist about getting a cavity if you are partly to blame by not following recommendations or not taking responsibility. Do you blame a tire manufacturer for a blowout after you drive over broken class and nails? It's the same thing. There are no guarantees given by dentists. If yours did, he/she made a major mistake. AnswerIt is not very common to have cavities after dental sealants have been put on teeth, unless the diet and hygiene are very bad. Put in mind that dental sealants only last about 5 years, and should be redone.AnswerI got sealants put on about 4 years ago and that dentist said I never had a cavity. I just went to another dentist and it seems once the sealants wear off a little you start getting tons of cavities (19 in my case). In order to stop those new cavities from the sealants you must get more sealants put in. Seems that when you have more sealants put on your teeth they prevent the cavities the old sealants caused. I would have been better off never having the sealants, before I only got one cavity every year or two... Now 19 in one year.
