Teeth have grooves, valleys, and pits on the biting surface. They are designed that way for optimal interlocking with the opposite teeth and food deflection. But in most teeth, these grooves are too narrow and small for toothbrushes to effectively remove stuck debris. This can lead to increase cavities; even with proper oral hygiene. Sealants are a plastic resin that bonds to the tooth. They are placed on the chewing surfaces of the back to protect them from plaque and acids.
They are excellent for kids, especially when the teeth have freshly erupted. These teeth haven’t been damaged by acids and bacteria. They are not recommended if the stain is already present on the teeth. The stain would need to be removed first. But they’re not solely for kids. Adults may have them also. Generally, dental insurance does not pay for sealants on adult patients. Contact your dental insurance provider to know your benefits of dental insurance.
This video shows you how dental sealants are applied to protect back teeth from bacteria and decay in children and adults.
