Dental Sealants in Woodbridge, ON
What is a dental sealant?
A dental sealant is a thin plastic coating that is placed on the top of the teeth, or on the chewing surface of the tooth. Your dentist may refer to this as the occlusal surface. Dental sealants are placed on the teeth that are located in the back of the mouth, also called the molar and premolar teeth. The purpose of the dental sealant is to protect the teeth from decay.
Why are they used on back teeth?
If you take a close look at your molar or premolar teeth, you will notice that they have grooves on the top of them. Some of these grooves may be very deep for some patients. Deep grooves provide an easy way for food debris and bacteria in the mouth to become trapped in or to settle into. By filling these grooves with a dental sealant, it will protect the top surfaces of the tooth from dental decay.
Dental Sealant Procedure
The tooth surface is thoroughly cleaned by your dental professional first, then washed and dried. An etching solution is placed on the surface of the tooth to create microscopic areas on the top surface of the teeth. The microscopic areas allow the dental sealant material to attach to the teeth easily. Next, the dental sealant material is placed in liquid form on the surface of the tooth. A special curing light is used to permanently harden the dental sealant material which completes the procedure.
If you consistently experience food getting stuck on the chewing surfaces or your teeth, or if you notice deep grooves in your teeth, dental sealants may be able to help.
