Two simple measures can make cavities less likely.
The chewing surfaces of back teeth have deep grooves where food and bacteria easily collect, and toothbrush bristles cannot always reach. Sealants are thin protective coatings painted into these grooves to keep debris out. Fluoride strengthens enamel and helps reverse very early decay. Together, they are common preventive steps recommended for many children, especially those at higher risk.
Families in Nixon can ask about sealants and fluoride at their child’s next visit to our Port Dover office. The dentist will assess your child’s teeth and risk of cavities, explain whether these treatments are recommended and describe how quick and comfortable the process usually is.
How they work
Sealants block, fluoride strengthens.
What sealants do
A sealant is a thin, tooth-coloured or clear coating that flows into the grooves of molars and premolars. Once hardened, it forms a smooth barrier that keeps food and bacteria out of hard-to-clean areas. Sealants do not replace brushing and flossing, but they add an extra layer of protection where many childhood cavities begin, particularly on newly erupted adult molars.
What fluoride does
Fluoride helps enamel resist acid attacks from bacteria and sugars. It can also help repair very early weak spots before they become cavities. Professional fluoride is usually applied as a varnish or gel that is painted onto the teeth. It works alongside fluoride toothpaste used at home, giving teeth more concentrated protection than daily brushing alone.
Who benefits
Recommendations are based on each child’s risk.
Children most likely to benefit
Sealants are often suggested for children’s permanent molars soon after they come in, typically during the school years, since these teeth have deep grooves and are prone to decay. Children with a history of cavities, deep pits in their teeth, braces or difficulty brushing thoroughly may benefit most. Some baby teeth with deep grooves may also be sealed.
Factors the dentist considers
The dentist looks at your child’s cavity history, diet, brushing habits, saliva and the shape of their teeth. They will explain why sealants or fluoride are recommended, or why they may not be needed right now. Ask questions about the benefits and how often fluoride should be applied, so you understand the reasoning behind the plan.
The appointment
Both treatments are quick and usually comfortable.
Placing sealants
The tooth is cleaned and dried, and a gentle solution is applied to help the sealant stick. The tooth is rinsed and dried again, then the sealant is painted into the grooves and hardened with a light. No drilling or freezing is usually needed. The process takes only a few minutes per tooth, and children can usually eat normally soon afterward.
Applying fluoride
Fluoride varnish is painted onto the teeth with a small brush. It may feel slightly sticky or have a mild taste. 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 based on the product used.
Ongoing care
Protection works best with good habits.
Checking sealants over time
Sealants can wear or chip over time, so the dentist checks them at regular visits and may repair or replace them if needed. Let the office know if your child feels a rough spot or a piece seems to be missing. Fluoride applications may be repeated at intervals depending on your child’s risk, and the dentist will suggest a schedule.
Daily habits still matter
Sealants and fluoride do not replace brushing, flossing and smart snacking. Help your child brush twice daily with fluoride toothpaste in an age-appropriate amount, and clean between teeth once they touch. Limit sugary snacks and drinks between meals. Regular checkups help catch any problems early, even on teeth that have been sealed. Water between meals is a simple habit that helps too.

Sealant and fluoride questions
Have a question about your situation? Our team can help you plan a visit.
Do sealants hurt?
No. Placing sealants usually does not require freezing or drilling. The teeth are cleaned and dried, and the sealant is painted on and hardened with a light. Most children find the process quick and comfortable, with nothing more than a slightly odd taste.
How long do sealants last?
Sealants can last several years, but they may wear or chip with chewing. The dentist checks them at regular visits and can repair or replace them if needed. Keeping up with checkups helps ensure they continue protecting the grooves of the teeth.
Is professional fluoride safe for children?
Professional fluoride is applied in controlled amounts by the dental team. It is widely used to help prevent cavities. The dentist will recommend fluoride based on your child’s age and risk and answer any questions you have about safety and frequency.
Can adults get sealants or fluoride?
Yes. Adults with deep grooves, a history of cavities, dry mouth or exposed root surfaces may benefit from sealants or professional fluoride. The dentist will assess whether these treatments would be helpful for your own teeth during your exam.
Do sealed teeth still need brushing?
Yes. Sealants protect only the chewing surfaces of the teeth. The sides and areas between teeth still need regular brushing and flossing to prevent cavities. Good daily habits remain the foundation of keeping teeth healthy for life.
