Prevention Fluoride and Sealants

Fluoride Treatments

What Fluoride Does

Fluoride strengthens the enamel of developing teeth, making them dramatically more resistant to decay. It also helps reverse very early cavities (white spot lesions) before they progress, and reduces bacterial activity in the mouth. Professionally applied fluoride uses a much higher concentration than children’s toothpaste — and it stays on the teeth for hours after application, giving the enamel the extra strength it needs.

How We Apply Fluoride

Fluoride varnish:
A sticky, lightly flavoured (often strawberry or bubblegum) coating painted directly onto the teeth with a tiny brush. Takes about 1–2 minutes. The child can eat soft foods afterwards but should avoid hot foods, hard foods or brushing for 4–6 hours.

Fluoride gel/foam in trays:
For older, more cooperative children. The fluoride is placed in a soft tray that fits over the teeth for1–4 minutes. The child doesn’t swallow it — they spit at the end.

How Often & From What Age

From age 3 onwards (when the child can reliably spit) — every 6 months
Children at higher risk of decay — every 3–4 months
Children with braces or appliances — every 3–4 months
Younger children (under 3) — varnish can still be applied if there's clinical indication

Is It Safe?

Yes — completely safe and endorsed by every major paediatric dental association in the world. The amount applied is tiny and controlled. The fluoride works topically (on the surface of the teeth), not systemically. We always discuss your child’s overall fluoride exposure (tap water, toothpaste, diet) sot he dose is right for your specific child.

Dental Sealants

What Sealants Are

Dental sealants are thin, tooth-coloured resin coatings painted into the deep grooves on the chewing surfaces of permanent back teeth. These grooves are often too narrow for even a single toothbrush bristle to reach — which makes them prime spots for cavities. Sealants smooth out the grooves so food and bacteria can’t get trapped.

How Effective Are They?

Sealants reduce the risk of decay in the protected teeth by up to 80%. For a five-minute, painless procedure, they’re one of the highest-return preventive treatments in all of dentistry.

When We Apply Sealants

First permanent molars ("6-year molars") — typically ages 6–7, as soon as the chewing surface is fully exposed
Second permanent molars ("12-year molars") — typically ages 11–13
Premolars — ages 10–12, where grooves are deep
Sometimes on baby molars in children at high risk of decay

How Long Do They Last?

5–10 years on average. We check sealants at every 6-monthly visit and repair or replace any that have worn — usually a quick 5-minute job.

The Procedure

Gentle cleaning of the chewing surface.

Drying and isolation of the tooth.

Mild etching gel applied for 15–20 seconds, then rinsed off.

Liquid sealant painted into the grooves with a small brush.

Cured (hardened) with a blue light for 20 seconds.

5–10 minutes per tooth. No drilling, no needles, no anaesthesia.

Diet Tips That Make a Big Difference

Limit sugary snacks between meals — frequency matters more than total amount
Sugary drinks (juice, fizzy drinks, flavoured milk) are major decay drivers — water is best
Never give a bottle with anything but water for sleep — this causes severe "bottle decay" in front teeth
Sticky sweets (toffees, gummies) are worse than chocolate — they cling to teeth
Cheese, plain yoghurt and nuts (age-appropriate) are tooth-friendly snacks
Rinse with water after any sweet treat

Everything You Need to Know

Frequently Asked Questions (FAQ)

Is fluoride safe for my child?

Yes. Professional fluoride treatments use controlled, topical doses that are completely safe. We always discuss your child’s total fluoride exposure (tap water, toothpaste, diet) to make sure the amount is appropriate for them. Fluoride is endorsed by all major children’s dental and paediatric medical associations.

Are dental sealants safe?

Yes — sealants have been used safely since the 1960s and are extensively researched. BPA-free options are available for parents who prefer them. At Dentistar we use modern, biocompatible sealant materials.

Can sealants be applied to baby teeth?

In most cases, sealants are placed on permanent teeth (from age 6 onwards). However, in children with very deep grooves on baby molars or a history of early decay, we may recommend sealing baby teeth too. We assess each child individually.

If my child has sealants, do they still need to brush?

Yes — absolutely. Sealants only protect the chewing surfaces of the back teeth. The front teeth, the sides of the back teeth, and the gums all still need brushing and flossing. Sealants are one layer of defence, not a replacement for daily care.

My child swallows the toothpaste — is that a problem?

Up to about age 3, that’s normal and why we use only a rice-grain-sized smear. From age 3–4, gently teach them to spit. Until then, the small amount of fluoride toothpaste they swallow is not harmful.

How can I get my child to brush without a fight?

Make it a routine, not a battle. Brush together (children imitate), let them choose a fun toothbrush, use a 2-minute song or video, try a reward chart for consistency. Avoid making it feel like a punishment — and never use it as a threat.

Are sealants covered by insurance?

Many insurance providers cover preventive paediatric care including sealants — especially because they save costs later. We provide detailed receipts for reimbursement.
