Dental sealants are protective barriers applied to the molars, the teeth located in the back of the mouth. These teeth are particularly prone to cavities due to their shape and the increased difficulty of cleaning these teeth since they are not as easily visible as the frontmost teeth.

Dental sealants, which are made of composite resin, are carefully applied onto the back teeth by your dental hygienist or dentist. This process is quick and completely painless.

Sometimes patients may be able to feel a sealant for a short while after it is first applied. Typically, this is only when you directly run your tongue against the sealant. This will only last a short while and will quickly become undetectable.

Dental sealants are at their most effective during the first two years after application. Up to 80% of cavities can be prevented during this time. However, the barrier remains 50% effective for up to four years and will continue to provide some level of protection for several years after this.

Sealants are at their most beneficial when placed on healthy teeth as a way to prevent decay from starting. During the earliest stages of decay, a sealant can sometimes be used to slow the progress. However, this is not ideal as decay can often continue beneath the surface of the protective barrier.

Dental sealants are most often used on the teeth of children up to the age of 18. Around age 6 is when the first sealants should be placed and then again at age 12.

Though they are most often given to children, sealants can also benefit adults. This protective barrier can help slow or prevent decay just as it would for younger patients.

However, sealants cannot prevent or improve issues like gum disease, receding gums, or advanced decay. Applying sealants may also just allow decay to continue beneath the surface.

Your dentist will be able to determine if you are a good candidate for this procedure based on the current health of your teeth.
