subject: To Seal Or Not To Seal? [print this page] Your teeth's topography is made up of natural grooves, pits, and fissures. While there's certainly nothing wrong with these topographical features, they can be ideal hiding spots for food particles, which can lead to plaque and cavity-causing decay.
Even with regular brushing and flossing, it is possible to miss some of these areas, particularly on hard-to-reach teeth like back molars. Adults and children who are plagued with cavities or just hoping to avoid them may consider having a dental sealant applied to their teeth.
What Is A Sealant?
Sealants are made out of a plastic resin material. When applied, it fills in the grooves in your teeth creating a smoother surface that makes brushing plaque from teeth easier. It also serves as a protective barrier between the tooth and food, protecting the enamel from decay.
A sealant is applied by your dentist. The first step is to thoroughly clean the teeth receiving the sealant. Next, your dentist will apply an etching gel to the teeth being treated. The etching gel is a slightly abrasive substance that will give your teeth some "teeth" to help the sealant adhere. Once the etching is complete and the teeth dry, your dentist will apply the sealant in liquid form to your teeth. A blue curing light is then used to set the sealant, and your dentist will check the bite to make sure the sealant is not too thick.
Sealants are typically placed on teeth where brushing is not completely effective, such as the hard-to-reach, deeply grooved back molars.
Who Is A Good Candidate?
Children are particularly good candidates for sealants. Sealants are typically used on children to help prevent decay and cavities during the years when they are most susceptible: after their permanent teeth come in, but before decay sets in. While sealants can be placed on children of any age, the teeth do need to be fully erupted and the child must be cooperative during the process.
Adults may also be good candidates for sealants. Because of their shape and grooves, some teeth may be more vulnerable to decay than others, so sealants may be a viable option for preventing decay.
How To Care For Your Sealed Teeth
Although the teeth have to be completely dry when applying the sealant, once set, there are no limitations to your eating or drinking habits.
Sealants typically last anywhere from 5-10 years and are checked during your routine dental visits. If you notice a sealant is partially or completely missing, contact your dentist. It is normal for sealants to last less than 5 years when applied to very young children. Because the teeth have to be completely dry during the application process, the cooperation of the child is an important component.
Decay, at any age, causes permanent damage to the teeth, even if promptly filled. Your dentist can help you decide if sealants would be a good addition to you or your child's oral hygiene program.
