Sealants
Protective coatings applied to molars to shield grooves from decay, especially helpful for kids and teens.
Sealants are thin resin coatings painted onto the deep grooves of back teeth, sealing out food and bacteria where toothbrush bristles can't reach. While fluoride protects smooth surfaces, sealants protect the chewing surfaces.

Every mouth is different. If your question is not here, call the office and we will answer it directly.
Do dental sealants hurt?
- No, applying a sealant is simple: we clean the tooth, paint on the sealant, and cure it with a quick light. There is no drilling or numbing involved.
Are sealants just for kids?
- Sealants are especially valuable for children with new permanent teeth, but they are great for adults too, especially anyone prone to cavities.
How long do dental sealants last?
- Sealants are long-lasting and hold up for years with normal care. Keeping up with regular exams and home care helps them protect your teeth for as long as possible.
Why are sealants recommended if I already use fluoride?
- Fluoride protects the smooth surfaces of your teeth, while sealants protect the chewing surfaces and deep grooves of your back teeth where a toothbrush can't fully reach.
How many visits does getting a sealant take?
- Getting a sealant takes one appointment. We clean the tooth, apply the sealant, and cure it with a quick light all in the same visit.
