Dental Sealants for Kids — Protect Back Teeth from Cavities
Dr. Arpita Dash
Dental Surgeon & Smile Specialist
Children often get cavities on the chewing surfaces of their back teeth. These teeth have deep grooves and pits that trap food and bacteria. Dental sealants are a simple, painless way to protect these teeth from decay. According to the CDC, school-age children without sealants have almost three times more cavities than children with sealants.
In India, dental caries is the most common chronic disease among children, affecting an estimated 50 to 60% of school children. In Bhubaneswar, many parents are not aware of sealants or delay getting them until cavities have already formed. Sealants are a quick, painless, and cost-effective preventive measure that can protect your child’s teeth for years.
At YourDentist Laser Dental Clinic in Bhubaneswar, Dr. Arpita Dash recommends sealants for children as soon as their permanent molars come in. This simple preventive measure can save your child from fillings, pain, and costly treatment later.
What are dental sealants?
Dental sealants are thin, protective coatings applied to the chewing surfaces of back teeth. They fill the deep grooves and create a smooth surface that is easier to clean and less likely to trap food.
How do sealants work?
Sealants act as a barrier between the tooth and bacteria. They:
- Fill deep pits and grooves
- Prevent food from getting stuck
- Make chewing surfaces easier to clean
- Reduce the risk of cavities by up to 80%
Which teeth should be sealed?
| Teeth | When to seal |
|---|---|
| First permanent molars | Around age 6 |
| Second permanent molars | Around age 12 |
| Premolars | If they have deep grooves |
| Baby molars | Sometimes, if high cavity risk |
The sealant procedure
Step 1: Cleaning
The tooth is cleaned and dried thoroughly.
Step 2: Conditioning
A special gel is applied to roughen the tooth surface slightly. This helps the sealant bond.
Step 3: Rinsing and drying
The gel is rinsed off and the tooth is dried again.
Step 4: Sealant application
The liquid sealant is painted onto the chewing surface.
Step 5: Curing
A special light hardens the sealant in seconds.
The whole procedure takes only a few minutes per tooth and is completely painless.
How long do sealants last?
Sealants can last 5 to 10 years with proper care. Dr. Dash checks sealants during regular checkups and reapplies them if they wear down.
Are sealants safe?
Yes, dental sealants are safe. They are made from dental resin and contain very low levels of BPA, which is not considered harmful. The benefits of preventing cavities far outweigh any minimal risk.
The American Dental Association and the Indian Dental Association both endorse dental sealants as a safe and effective preventive treatment for children.
Sealants and fluoride: how they work together
Sealants and fluoride protect teeth in different ways:
| Protection | Sealants | Fluoride |
|---|---|---|
| What it protects | Chewing surfaces of back teeth | All tooth surfaces |
| How it works | Physical barrier | Strengthens enamel |
| Best for | Grooves and pits | Smooth surfaces |
| Applied by | Dentist | Toothpaste, water, dentist |
Both are important for comprehensive cavity prevention. Dr. Dash recommends both sealants and fluoride treatment for children at high risk of cavities.
When sealants may need reapplication
Sealants can wear down over time, especially if your child:
- Grinds their teeth
- Chews hard foods frequently
- Eats sticky candies regularly
- Has habits like chewing on pens
Dr. Dash checks sealants at every 6-month checkup. If a sealant is chipped or worn, she can reapply it quickly and painlessly.
Sealants vs fillings
| Factor | Sealants | Fillings |
|---|---|---|
| Purpose | Prevent cavities | Repair cavities |
| Tooth reduction | None | Removes decayed tooth |
| Cost | ₹500 - ₹1,500 per tooth | ₹800 - ₹2,500 per tooth |
| Pain | Painless | May need anaesthesia |
| Time | 5 to 10 minutes per tooth | 20 to 40 minutes |
Sealants are a preventive treatment. Fillings are a repair treatment. Prevention is always better.

Caring for teeth with sealants

Sealant cost savings over time

| If 2 molars get cavities | ₹1,600 - ₹5,000 (fillings) | ₹0 (prevented) | ₹1,600 - ₹5,000 |
| If cavity reaches pulp | ₹3,000 - ₹10,000 (RCT + crown) | ₹0 (prevented) | ₹3,000 - ₹10,000 |
| If tooth is lost | ₹25,000 - ₹50,000 (implant) | ₹0 (prevented) | ₹25,000 - ₹50,000 |
Sealants are one of the most cost-effective preventive treatments in dentistry. A small investment now can save significant costs and pain later.

Frequently asked questions

Are sealants painful? No, sealant application is completely painless and does not require drilling or anaesthesia.
How much do sealants cost? Sealants cost ₹500 to ₹1,500 per tooth at YourDentist.
Do sealants really prevent cavities? Yes, sealants can reduce the risk of cavities on molars by up to 80%.
Can adults get sealants? Yes, adults with deep grooves and no decay can also benefit from sealants.
Do sealants contain BPA? Sealants contain trace amounts of BPA, but the level is extremely low and not considered harmful. The protective benefits far outweigh any minimal risk.
Can sealants come off? Yes, sealants can wear down or come off over time. Dr. Dash checks them at every checkup and can reapply them if needed.
Are sealants visible on teeth? Sealants are clear or tooth-coloured and are not noticeable when your child smiles or talks.
Can my child eat normally after getting sealants? Yes, your child can eat normally immediately after the procedure. There are no restrictions.
How are sealants different from fluoride treatment? Sealants protect the chewing surfaces by creating a physical barrier over grooves and pits. Fluoride strengthens all tooth surfaces by making enamel more resistant to acid. Both work together for complete protection. Dr. Dash recommends both for children at high cavity risk.
Can sealants be applied over early cavities? In some cases, sealants can be applied over very early, non-cavitated lesions to stop progression. Dr. Dash will assess whether the decay has gone too deep for sealant application. If it has, a filling is needed instead.
Are sealants covered by insurance? Some dental insurance plans cover sealants for children under a certain age. We provide detailed invoices with procedure codes for insurance submission. Check with your provider for coverage details.
