Two simple steps can help keep cavities away.
Back teeth have deep grooves where food and bacteria easily collect, and young enamel can be vulnerable to decay. Sealants are thin protective coatings painted onto the chewing surfaces of molars to seal those grooves. Fluoride treatments, usually a varnish brushed onto the teeth, help strengthen enamel and make it more resistant to acid.
For Selkirk families, these preventive steps can often be added to a child’s regular checkup at our Port Dover office, which helps keep the number of trips down. The dentist will assess your child’s risk of decay and explain whether sealants, fluoride or both are likely to be helpful.
Understanding sealants
Sealants form a barrier in the grooves.
How sealants protect teeth
A sealant is a liquid resin that flows into the pits and grooves of a tooth and hardens into a smooth surface. This makes it harder for food and bacteria to become trapped and easier to clean with a toothbrush. Sealants do not replace brushing and flossing, but they can add a layer of protection where cavities often begin.
Which teeth benefit most
Sealants are most commonly placed on permanent molars soon after they come in, usually around ages six and twelve. Some baby molars or premolars with deep grooves may also benefit. The dentist will check the teeth for any existing decay before sealing, since sealants are meant to protect healthy surfaces rather than cover existing cavities.
Understanding fluoride
Fluoride helps teeth resist decay.
How fluoride strengthens enamel
Fluoride helps rebuild weakened enamel and makes teeth more resistant to the acids produced by bacteria. It can even help reverse very early signs of decay. Professional fluoride varnish provides a concentrated dose that sticks to the teeth for several hours, complementing the lower levels in toothpaste and, where present, in drinking water.
Who may benefit
Children with a history of cavities, frequent snacking, orthodontic appliances, enamel defects or difficulty brushing may benefit most from professional fluoride. The dentist will consider your child’s risk factors and whether your household uses well water or municipal water, as this can affect how much fluoride your child is already receiving.
The appointment
Both treatments are quick and painless.
Placing sealants
For sealants, the tooth is cleaned and dried, a mild solution is applied to help the sealant bond, then rinsed off. The sealant liquid is painted into the grooves and hardened with a special light. No drilling or numbing is usually needed. The dentist checks the bite afterward to make sure it feels comfortable and smooth.
Applying fluoride varnish
Fluoride varnish is painted onto the teeth with a small brush. It sets quickly when it contacts saliva. Your child may notice a slight taste or a temporary yellowish tint. The team will give instructions, which often include avoiding hard or hot foods and brushing for a few hours afterward to allow the varnish to work.
Ongoing protection
Prevention works best when it is consistent.
Caring for sealants
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. Encourage your child not to chew ice or hard candy, which can damage sealants. Let the office know if a sealant seems to have come off or if your child reports a rough spot.
Combining with daily habits
Sealants and fluoride work best alongside brushing twice daily with an amount of fluoride toothpaste suited to your child’s age, cleaning between teeth and limiting sugary snacks and drinks. Regular checkups allow the dentist to monitor your child’s teeth and recommend repeat fluoride treatments when appropriate.
Planning your appointment
Adding prevention to a Selkirk family visit.
When booking your child’s checkup at our Port Dover office, ask whether sealants or fluoride might be recommended so time can be allowed for them at the same appointment.
Mention whether your home uses well water or municipal water, and share any history of cavities in your child’s teeth.

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, usually around ages six and twelve. Some baby molars may also benefit. The dentist will examine your child’s teeth and recommend timing based on their development and decay risk.
Does getting sealants hurt?
No. Sealants are painted onto the tooth surface without drilling or needles in most cases. The process is quick, and children usually tolerate it well. Some may notice a new feeling on the tooth surface for a short time afterward.
How long do sealants last?
Sealants can last several years but may wear or chip over time. The dentist checks them at regular visits and can repair or replace them as needed. Avoiding hard foods and ice helps them last longer between checks.
Is fluoride varnish safe for children?
Fluoride varnish is widely used in children’s dental care and is applied in small amounts. The dentist will consider your child’s age and risk factors before recommending it. Ask any questions you have about its use at the appointment.
Do sealants replace brushing?
No. Sealants protect the chewing surfaces of back teeth, but cavities can still form between teeth and along the gums. Brushing twice daily, cleaning between teeth and limiting sugary snacks remain essential for your child’s dental health.
