Like armor for your teeth, tooth sealants are applied to your chewing surfaces to prevent cavities. The thin coating bonds into the vulnerable nooks and crannies of your back teeth, thereby “sealing out” plaque and food and forming a protective shield over the enamel.


Tooth sealants can help children and teenagers get through their more cavity-prone years, until good brushing and dental home care habits are established.


Sealants can protect teeth from decay for up to 10 years, but they need to be checked for chipping or wearing at your regular dental exams.
