I got dental sealants. there are two teeth directly in contact and it feels and looks way too high and thick and i can't fully close my mouth.

Call your dentist: Dental sealants will wear down slightly with time, but they are plastic and can take a long time. Your mouth is very sensitive to even the littlest change, but if it does not feel normal to you, you should let your dentist know.

See your dentist: Sealants are usually placed using a creamy bonding material, it normally flows and fills the gaps between the cusps, unfortunately if you overfill the gaps, the hardened sealant can hit the opposing tooth early. If this is the case it is best to go back to the dentist and have him or her reduce it with a marking paper. This will usually do the trick.

See your dentist : for adjustment. When a dental sealant is too high in the bite, the jaw does not close properly and it causes further pressure to the TMJ area leaving the muscle unable to relax and in contraction. Can cause the TM disorder. Simple adjustment will solve the problem.

Applied to thick: Go back to your dentist and have them smooth down the excess sealant. Small amounts of excess sealant can "self adjust" as you eat. Large amounts of excess need to be smoothed down by your dentist. This is both quick and painless.

Go back to your DDS: If it feels like you cant fully close your mouth after fillings or sealants the bite may need an adjustment. I suggest you go back to the dentist who did them to check if an adjustment is needed.

Dental Sealants: It's quite common for the sealants to be a bit "high" for a day or two. They usually wear down on their own. Why are you not directing your concerns with your dentist?

Go Back: Go back to the Dentist and have the bite checked. Often there is too much material left and it requires adjustment. Do not wait. Smart thinking on your part. Good Luck.
