Two simple treatments can help keep cavities away.
Children’s back teeth have deep grooves where food and bacteria easily collect, and young enamel is still maturing. Sealants and fluoride are two preventive treatments that can add protection. Sealants cover the grooves with a thin coating, while fluoride helps strengthen enamel. Neither replaces brushing, but both can reduce the risk of decay in many children.
Families from Boston can ask about sealants and fluoride during their child’s visits to our Port Dover office. The dentist will consider your child’s teeth, cavity history and habits, and explain whether either treatment would likely benefit them, and how often it might be repeated as they grow.
Understanding sealants
Sealants fill in grooves that brushes struggle to reach.
How sealants protect
A sealant is a thin, protective coating painted onto the chewing surfaces of back teeth. It flows into the deep pits and grooves, creating a smoother surface that is easier to clean and harder for bacteria to settle into. Sealants are most effective when applied before decay has started, often soon after adult molars come in.
Which teeth are sealed
Permanent molars are the most common candidates, especially the first and second molars that arrive around ages six and twelve. Baby molars with deep grooves may sometimes be sealed too. The dentist will look at each tooth to decide whether a sealant is likely to help. Teeth that already have fillings in the grooves usually do not need one.
Understanding fluoride
Fluoride strengthens enamel and helps repair early damage.
How fluoride helps enamel
Fluoride is a mineral that helps make enamel more resistant to acid attacks from bacteria and sugars. It can also help repair very early weak spots before they become cavities. Children with a history of decay, braces or limited access to fluoridated water may particularly benefit from extra fluoride. Families on private wells may want to mention their water source.
Professional versus home fluoride
Professional fluoride treatments use a varnish or gel that is stronger than toothpaste and is applied at the office. Daily fluoride toothpaste in an amount suited to your child’s age provides ongoing protection at home. The dentist will recommend what is appropriate based on your child’s individual risk. Supervise young children so they spit out toothpaste rather than swallow it.
Treatment day
Both treatments are quick and usually comfortable.
Applying sealants
For sealants, the tooth is cleaned and dried, a conditioning solution is applied and rinsed off, then the sealant is painted on and hardened with a light. No numbing or drilling is usually needed. The whole process takes only a few minutes per tooth, and children can eat normally afterward. Several teeth can usually be sealed in one short visit.
Applying fluoride
Fluoride varnish is painted onto the teeth with a small brush. It sets quickly and may feel slightly sticky. Your child may be asked to avoid eating hard foods or brushing for a few hours afterward so the fluoride has time to work. The team will give you specific instructions. Most children find varnish quick and painless, though some dislike the taste.
Ongoing care
Sealants and fluoride work best alongside daily care.
Checking sealants at visits
Sealants can last several years but may wear or chip over time. The dentist will check them at regular visits and repair or reapply them if needed. Let the team know if your child feels a rough spot or something seems to have come off a back tooth. Lost sealants can usually be redone quickly.
Keeping up good habits
Brushing twice daily with fluoride toothpaste, flossing where teeth touch and limiting sugary snacks and drinks remain essential. Sealants protect chewing surfaces but not the spaces between teeth. Fluoride helps but cannot overcome frequent sugar exposure. Good habits at home complete the protection that sealants and fluoride begin. Regular checkups tie it all together for your child.
Planning your appointment
Asking about preventive treatment from Boston
Call our Port Dover office to book a checkup and ask whether sealants or fluoride would suit your child. The dentist can assess their teeth and recommend what makes sense.
If you know whether your home water is from a well or municipal supply, mention it, since this can affect fluoride recommendations.

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 soon after permanent molars come in, around ages six and twelve. The dentist will check your child’s teeth and recommend timing based on how deep the grooves are and their cavity risk.
Do sealants hurt?
No. Applying sealants usually involves no numbing or drilling. The teeth are cleaned, prepared and painted, then the sealant is hardened with a light. Most children find it quick and easy, and they can eat normally straight afterward.
Is professional fluoride safe for children?
Professional fluoride is commonly used in children’s dentistry and is applied in controlled amounts. The dentist will recommend it based on your child’s age and risk. Ask any questions you have during the visit or beforehand.
How long do sealants last?
Sealants can last several years with normal wear. The dentist will check them at regular visits and repair or reapply them if they have chipped or worn away. Touch-ups are usually quick and need no numbing.
Do sealants replace brushing?
No. Sealants protect only the chewing surfaces of back teeth. Brushing, flossing, fluoride toothpaste and limiting sugary snacks are still needed to protect all surfaces of the teeth, especially the tight spaces between them where decay often starts.
