Your molars and pre-molars, the strong chewing teeth towards the back of your mouth, are especially prone to cavities. A sealant is a protective layer of a plastic-like dental resin that your dentist can use to cover these chewing teeth to keep out plaque and prevent decay.
The Sealant Procedure
To make sure the teeth are clean and healthy, first you will receive an exam and a thorough cleaning. Then your teeth will be prepped with an etching solution that will help the sealant form a tight bond. Your dentist will apply the dental resin with a brush, like paint, making sure that all surfaces are covered. A special light is then used to harden and cure the sealant. At this point, your dentist will check your bite, and make any necessary adjustments.
Once completed, the sealants should last for years. You won't even notice they are there, and you can eat all the foods you normally would. If they wear down or come loose, they can be replaced just as easily as they were initially applied. There's no danger in swallowing the dental resin, as it is completely non-toxic.
