Extra Protection Against Cavities for Children and Adults
At North Arbor Dental, our focus is on prevention — stopping dental problems before they start. Dental sealants are a quick, painless, and highly effective way to protect back teeth from cavities, especially in children and teens.
Sealants act as a barrier, preventing plaque and food particles from settling into the grooves of molars where brushing may not reach. If you're looking for a trusted dentist in Kitchener Waterloo offering conservative, preventive care for your family, we’re here to help.
What Are Dental Sealants?
Dental sealants are thin, clear or tooth-colored coatings applied to the chewing surfaces of back teeth (molars and premolars). These areas are especially prone to decay because of their deep grooves and pits.
Sealants work by:
- Smoothing out tooth surfaces to make them easier to clean
- Blocking bacteria and food from settling in grooves
- Reducing the risk of cavities by up to 80 percent in molars
- Offering long-lasting protection with minimal upkeep
Sealants are most commonly applied to children’s permanent molars, but they can also benefit cavity-prone teens and adults.
Who Should Get Sealants?
We typically recommend dental sealants for:
- Children: As soon as permanent molars emerge (usually around age 6 and again around age 12)
- Teens: Especially those with deep grooves or difficulty maintaining oral hygiene
- Adults: With no existing decay or fillings in their molars but who are prone to cavities
Sealants are part of our comprehensive family dentistry approach, supporting long-term oral health through simple, low-cost prevention.
What to Expect During Treatment
Sealant application is fast, painless, and non-invasive — often completed during a routine cleaning and exam.
Steps:
- The tooth is cleaned and dried
- A bonding solution is applied to help the sealant adhere
- The liquid sealant is painted onto the grooves of the tooth
- A special curing light hardens the material instantly
- The tooth is checked to ensure a smooth, comfortable bite
There’s no drilling, no numbing, and no downtime. Once placed, sealants can last several years with proper care.
Are Sealants a Substitute for Brushing?
No. Sealants are a valuable supplement, not a substitute, for good oral hygiene. We still recommend:
- Brushing twice daily with fluoride toothpaste
- Daily flossing
- Fluoride treatments when appropriate
- Regular dental checkups and professional cleanings
As your dentist in Kitchener Waterloo, we help you combine professional care with smart at-home habits to protect your smile for the long term.
