Dental Sealants in Toronto’s Distillery District

A thin protective coating painted into the grooves of back teeth, sealing out the decay that loves places a toothbrush can’t reach. No drilling, no freezing, done in minutes — and one of the best-evidenced preventive treatments in dentistry.

Why back teeth need help

Look closely at a molar and you’ll see a landscape of pits and grooves — the fissures that make chewing work. Some of those grooves are narrower than a single toothbrush bristle, which means they can hold food and bacteria that brushing genuinely cannot remove. That’s why the overwhelming majority of cavities in children and teenagers happen on chewing surfaces rather than anywhere else.

A sealant fills those grooves with a flowable resin and hardens it, turning a rough, food-trapping surface into a smooth one a brush can actually clean. It’s prevention in the most literal sense: the cavity never starts.

Who sealants are for

• Children, as permanent molars arrive — the first around age six, the second around twelve. Sealing them soon after they erupt is the highest-value moment
• Teenagers — particularly through the years when brushing is, let’s say, variable
• Adults with deep grooves and no existing decay — less common, but entirely reasonable where the anatomy invites trouble
• Anyone with a history of decay on chewing surfaces — past cavities predict future ones

What the appointment involves

Very little, which is rather the appeal. We clean and dry the tooth, apply a conditioning gel that helps the sealant bond, rinse and dry again, then paint the resin into the grooves and set it with a curing light. A few minutes per tooth, no anaesthetic, nothing to feel afterward beyond a slightly different bite for an hour or so.

Sealants are usually placed at the same visit as a cleaning and checkup, and we check them at every subsequent visit — they can chip or wear, and topping one up is far easier than treating the decay underneath.

Coverage in Ontario

Sealants are among the better-covered preventive treatments in Ontario, particularly for children. Most private plans cover them for patients under a certain age — often the mid-teens — and reimburse in line with standard Ontario dental plan guidelines. Adult sealants are covered less consistently, so we always check first.

For families without private coverage, two public programs matter: Healthy Smiles Ontario provides free preventive and routine dental care — including sealants — for eligible children and youth aged 17 and under in qualifying households, and the Canadian Dental Care Plan (CDCP) includes sealants among its covered services. We’re glad to help you work out which applies. See insurance options and payment options.

Straight answers

At what age should my child get sealants?

Soon after each set of permanent molars comes in — typically around age six for the first molars and around twelve for the second. Sealing them while the grooves are still pristine is when sealants do the most good. We’ll flag the right moment at your child’s checkups so you don’t have to track it.

How long do dental sealants last?

Several years, often longer, and they can be repaired or reapplied if they chip. Because they take normal chewing forces, we check them at every visit rather than assuming they’re intact — a partially worn sealant is worth topping up before anything gets underneath it.

Do sealants hurt? Is there drilling?

Neither. Nothing is removed from the tooth, no anaesthetic is needed, and most children find it the easiest appointment they have with us. If your child is anxious about dental visits generally, tell us when you book — sealants are often a good first experience precisely because nothing about them is uncomfortable.

Are dental sealants safe?

Yes. Sealants are well studied and widely recommended by dental and public health organizations as an effective way to prevent decay in children. Some parents ask about BPA: sealant materials may contain trace amounts, at levels far below established safety thresholds and comparable to everyday environmental exposure, and the consensus is that the protective benefit clearly outweighs that risk. We’re happy to discuss the materials we use — it’s a fair question to ask.

Sealants work best alongside the rest of preventative care: cleanings, fluoride, and the complete oral exam that identifies which teeth would benefit. When decay does happen, it becomes a filling — which sealants exist to avoid. Browse all preventative dentistry.
