Dental sealants protect children's back teeth from decay, quick, painless and highly effective. Available in Waterdown at (289) 799-3355.
The chewing surfaces of back molars are covered in deep grooves, narrower than a single toothbrush bristle. Food and bacteria settle into them and no amount of good brushing reliably gets them out. That is why the overwhelming majority of childhood cavities occur on these surfaces. A sealant is a thin protective coating flowed into those grooves and hardened with a curing light. It seals the vulnerable surface completely.
no freezing, no drilling.
A conditioning gel is applied for a few seconds and rinsed away.
The liquid sealant is painted into the grooves.
A blue curing light hardens it in seconds.
Your child’s bite is checked and they are done.
First permanent molars arrive around age six, second permanent molars around age twelve. Sealing them soon after they erupt gives the best protection, because the grooves have had the least time to accumulate bacteria. Baby molars can also be sealed in children at high cavity risk.
Sealants commonly last several years and are checked at every routine visit. If one chips or wears, it is simply topped up, again without freezing or drilling.
Modern sealants release only trace amounts, far below any level of concern, and the cavity-prevention benefit is well established. We are happy to discuss the specific material we use.
Yes. Sealants protect the grooves, not the sides of the teeth or the gumline.
