Regular dental exams are an important part of preventive health care.
Dental sealants are invisible plastic resin coatings that smooth out the chewing surfaces of the back teeth, making them resistant to decay. A sealed tooth is far less likely to develop a cavity, require more expensive dental treatment later on, or most importantly, cause your child pain.
How Sealants Are PlacedYou can think of a sealant as a mini plastic filling, though please reassure your child that it doesn’t count as having a cavity filled. Because tooth enamel does not contain any nerves, placing a sealant is painless and does not routinely require numbing shots. First, the tooth or teeth to be sealed are examined, and if any minimal decay is found, it will be gently removed. The tooth will then be cleaned and dried. Then a solution that will slightly roughen or “etch” the surface is applied, to make the sealing material adhere better. The tooth is then rinsed and dried again. The sealant is then painted on the tooth in liquid form and hardens in about a minute, sometimes with the help of a special curing light. That’s all there is to it!
Taking Care of Sealants
Sealed teeth require the same conscientious dental hygiene as unsealed teeth. Your child should continue to brush and floss his or her teeth daily and have regular professional cleanings. Checking for wear and tear on the sealants is important, though they should last for up to 10 years. During this time, your child will benefit from a preventive treatment proven to reduce decay by more than 70 percent.
