Caring for St. Williams patients at our office in Port Dover
Every dental service for St. WilliamsExtra protection for growing teeth
Two simple treatments that help keep cavities away.
Back teeth have deep grooves where food and bacteria can hide, making them prone to decay. Sealants are a thin coating painted onto these grooves to create a smoother surface that is easier to clean. Fluoride treatments, often applied as a varnish, help strengthen enamel and make it more resistant to acid. Together, they are common preventive measures for children.
Families in St. Williams can ask about sealants and fluoride during their child’s checkup at our Port Dover office. The dentist will look at your child’s teeth and cavity risk and explain whether these treatments are likely to help.
Sealants explained
Sealants act as a barrier in the grooves.
How sealants protect teeth
A sealant fills the pits and grooves on chewing surfaces, preventing food and bacteria from settling into them. This makes the tooth easier to clean with a toothbrush and lowers the risk of cavities starting in those areas. Sealants do not replace brushing but add an extra layer of protection.
Which teeth benefit most
Permanent molars are the most common teeth to seal, often soon after they come in during childhood. Some baby molars with deep grooves may also benefit. The dentist will check which teeth have grooves at risk of decay and recommend sealants where they are likely to help.
Fluoride explained
Fluoride helps teeth resist decay.
How fluoride strengthens enamel
Fluoride helps rebuild weakened enamel and makes teeth more resistant to acid produced by bacteria. It can also help reverse very early signs of decay. Fluoride toothpaste is the main source for most children, while professional treatments provide a more concentrated boost for those at higher risk.
Professional fluoride treatments
A fluoride varnish is painted onto the teeth and sets quickly. It is generally well tolerated by children. The dentist will recommend how often fluoride treatments are helpful based on your child’s cavity risk, diet and oral hygiene. Ask about any questions you have regarding fluoride.
The appointment
Both treatments are quick and comfortable.
Placing sealants
The tooth is cleaned and dried, and a gentle solution is applied to help the sealant stick. The sealant is painted into the grooves and hardened with a special light. No freezing or drilling is usually needed. Each tooth takes only a few minutes, and children can eat normally afterward.
Applying fluoride
Fluoride varnish is brushed onto the teeth after a cleaning or checkup. It may feel slightly sticky. Your child may be asked to avoid eating hard foods or brushing for a short time afterward so the fluoride can work. The team will give specific instructions.
Ongoing care
Prevention continues at home.
Checking sealants at visits
Sealants can last several years but may wear or chip. The dentist will check them at regular visits and repair or replace them if needed. Let the office know if your child says a sealant feels rough or has come off.
Daily habits that help
Brushing twice a day with a fluoride toothpaste in an amount suitable for your child’s age, cleaning between teeth and limiting sugary snacks and drinks are still essential. Sealants protect chewing surfaces but not the spaces between teeth, where cavities can also form.
Planning your appointment
Preventive treatments for St. Williams children.
Ask about sealants and fluoride when booking your child’s checkup at our Port Dover office. The team can tell you whether these treatments might be helpful.
If your child’s new molars have recently come in, mention it, as this is often a good time to consider sealants.

Sealant and fluoride questions
Have a question about your situation? Our team can help you plan a visit.
At what age should my child get sealants?
Sealants are often placed on permanent molars soon after they erupt, commonly in early school years and again in the preteen years. The dentist will recommend timing.
Do sealants hurt?
No. Sealants are painted onto the tooth surface without freezing or drilling in most cases. The process is quick and comfortable for most children.
Is fluoride safe for children?
Fluoride used appropriately is considered safe and effective for preventing cavities. Use the recommended amount of toothpaste for your child’s age and follow the dentist’s advice.
How long do sealants last?
Sealants can last several years, but they should be checked at regular visits. Worn or damaged sealants can be repaired or replaced.
Do sealants replace brushing?
No. Sealants protect chewing surfaces but not the areas between teeth. Brushing twice daily and cleaning between teeth are still essential.
