Fillings and sealants

Fillings and sealants


Cavities can happen to anyone, even those with perfect dental hygiene habits. But while a small cavity is nothing to get too worked up about, it should be addressed ASAP. Left undiagnosed and untreated, bacteria and decay can travel deeper into your tooth. This can result in you needing a crown, root canal, or even an extraction.

The Centre de santé dentaire Dre Thu Nguyen is the best place to get a dental filling in Châteauguay. With our preventative approach, state-of-the-art technology, and natural-looking filling materials, we make getting a dental filling easy and comfortable.


A dental sealant is a clear material that’s carefully painted and bonded onto your tooth’s surface. This treatment “seals” the pits and grooves of your teeth, keeping bacteria from getting caught in the crevices and damaging your enamel!

Here at our clinic in Châteauguay, our dental sealants are made from an ultra-thin, non-toxic resin and are great for patients of all ages, but we often recommend this as a great option for children’s first permanent back teeth.
