What Is a Dental Sealant?
A dental sealant is a thin protective coating flowed into the deep grooves on the chewing surface of a back tooth and hardened with a curing light. It creates a physical barrier that seals out the food and bacteria that start decay, on the one part of the tooth a toothbrush genuinely cannot clean properly.
Look closely at a six-year molar and the grooves are narrower than a single toothbrush bristle. Food and plaque settle into them and stay there. That is why the great majority of childhood cavities start on chewing surfaces rather than between teeth, and why the Canadian Dental Association reports sealants cut decay risk on treated surfaces by up to 80 percent in the first two years.
What Is Fluoride Treatment and How Is It Different?
Fluoride is a naturally occurring mineral that incorporates into enamel and makes it more resistant to the acid that dissolves it. Professionally applied fluoride varnish is far more concentrated than toothpaste and is painted directly onto the teeth, where it stays in contact for hours.
The two treatments do different jobs and are not alternatives to one another. A sealant physically blocks the grooves on a specific chewing surface. Fluoride strengthens every surface of every tooth, including the areas between teeth that sealants cannot reach. Most children at Brampton Smiles receive both, and fluoride can sometimes reverse a very early lesion before it ever becomes a cavity.
When Should My Child Get Sealants at Brampton Smiles?
Timing matters more than most parents realize. Newly erupted enamel takes roughly three years to fully mature and harden, so a molar is at its most vulnerable in exactly the period right after it comes through. Sealing it early captures that window.
- Around age 6. The first permanent molars erupt behind the baby teeth. Many parents do not notice they have arrived, because nothing falls out first.
- Around age 12. The second permanent molars erupt further back.
- Premolars, as they come in. Sealed where the grooves are deep enough to warrant it.
- Baby molars, in higher-risk children. Where a child already has decay or particularly deep grooves.
- Adults. Sealants are not only for children. Deep unrestored grooves in an adult molar can be sealed too.
How Does Brampton Smiles Apply Sealants and Fluoride?
Both are short, painless appointments with nothing to recover from. Children eat normally the same day, and most are surprised by how little happens.
- Clean and dry the tooth (a few minutes). The chewing surface is polished and isolated so it stays completely dry.
- Condition and rinse. A mild gel is applied briefly to help the sealant bond, then rinsed away.
- Flow and cure the sealant (about 10 minutes per tooth). The liquid sealant is placed into the grooves and hardened with a light. The bite is checked afterwards.
- Fluoride varnish (about 2 minutes). Painted on at the end of the hygiene visit. Your child avoids hot drinks and hard or crunchy food for a few hours so it stays in contact.
The six-year molars are the ones families miss, because no baby tooth falls out to announce them. Parents assume nothing has changed and the tooth sits unsealed through the years when it is softest. We start looking for them at every recall from age five, specifically so we are not sealing a molar that already has decay in it.
Is Fluoride Safe for Children?
Yes, at the doses used in professional treatment and in toothpaste. Fluoride has been studied for decades and is endorsed by the Canadian Dental Association, Health Canada, and the World Health Organization as a safe and effective way to prevent decay.
The practical guidance we give parents in Brampton concerns amount, not safety. Use a smear no larger than a grain of rice for children under 3, and a pea-sized amount for ages 3 to 6, and supervise brushing so it gets spat out rather than swallowed. Dr. Abbas reviews your child’s total fluoride exposure, including water and any supplements, before recommending anything additional.
How Long Do Sealants Last and Do They Need Checking?
Sealants commonly last several years, and many stay intact well beyond that. They do wear at the edges under chewing, and a partially lost sealant should be repaired rather than left, because a gap can trap debris underneath.
Our hygiene team checks every sealant at each 6-month recall and tops up any that have chipped, which takes a few minutes and requires no freezing. Sealants are a supplement to brushing, flossing, and diet rather than a replacement for them, and a sealed molar can still develop decay between teeth.
Are Sealants and Fluoride Covered at Brampton Smiles?
The Canada Dental Care Plan covers eligible Canadian children fully for sealants and fluoride, with no out-of-pocket cost, and Brampton Smiles is a participating CDCP provider. Most extended dental plans cover children’s preventive services at a high percentage, often up to a set age.
We verify coverage before the appointment and direct-bill on the day. See CDCP details. Appointments run until 8 PM on Monday, Wednesday, and Thursday, with alternating Saturdays, so preventive visits do not have to mean missing school.
“Sealants are the best value in everything I do. Ten minutes, no freezing, no drill, and it protects the surface where most childhood cavities actually start. The children I end up restoring at nine or ten are almost never the ones whose molars we sealed at six. It is not a close comparison.”
Frequently Asked About Sealants & Fluoride at Brampton Smiles
Do dental sealants hurt at Brampton Smiles?
No. Applying a sealant involves no freezing, no needle, and no drilling. The tooth is cleaned, dried, conditioned, and the coating is flowed into the grooves and hardened with a light. It takes about 10 minutes per tooth. Most children at our Brampton office are surprised by how little there is to it.
Can a tooth with a sealant still get a cavity?
Yes, but far less often on the sealed surface. A sealant protects the chewing surface grooves, not the areas between teeth or at the gumline. Daily brushing, cleaning between teeth, fluoride, and limiting how often sugar is in the mouth all still matter. Dr. Azher Abbas, DMD, checks sealed teeth at every 6-month recall.
Are sealants at Brampton Smiles only for children?
No. Adults with deep unrestored grooves in their molars are candidates too, particularly patients with a history of decay, dry mouth from medication, or gum recession. The application is identical and equally painless. Dr. Abbas will point out any adult tooth where sealing makes clinical sense during your regular exam in Brampton.
Can my child eat after fluoride varnish at Brampton Smiles?
Soft food and cool drinks are fine right away. We ask families to avoid hot drinks, alcohol-containing rinses, and hard or crunchy food for a few hours so the varnish stays in contact with the enamel. The varnish may leave a temporary dull or yellowish film that brushes away that evening, which is normal.
Does CDCP cover sealants and fluoride at Brampton Smiles?
Yes. The Canada Dental Care Plan covers eligible Canadian children for preventive services including sealants and fluoride, generally with no out-of-pocket cost. Brampton Smiles is a participating CDCP providerand confirms coverage before the appointment. Most extended dental plans also cover children’s preventive care at a high percentage.
