Dental sealants are a simple, painless way to protect children’s back teeth from decay - and one of the most cost-effective preventive treatments in dentistry. A thin protective coating is painted onto the chewing surfaces of the molars, sealing out the food and bacteria that cause cavities. Here’s how they work and who benefits.
Sealants work alongside good habits and fluoride, not instead of them. See our cavity-prevention guide for the full daily picture.
Why Back Teeth Need Extra Protection
The chewing surfaces of the back molars are covered in tiny grooves and pits that trap food and plaque - and they’re very hard for a toothbrush to clean fully, especially for children still developing their brushing skills. That makes these surfaces the most common place for decay to start. A sealant smooths over the grooves so plaque can’t settle in them.
How Sealants Are Applied
- Cleaning - the tooth is cleaned and dried
- Preparation - a gel is applied briefly to help the sealant bond, then rinsed off
- Painting on - the liquid sealant is flowed into the grooves
- Setting - a curing light hardens it in seconds
- The whole process is quick, painless, and needs no drilling or anaesthetic
Who Should Have Them
- Children and teenagers - ideally soon after the adult molars come through (around ages 6 and 12)
- Children at higher risk of decay
- Anyone with deep grooves in their back teeth
- Sometimes adults with deep, decay-free grooves
- They’re applied to healthy teeth - not ones that already have decay
Key fact: Sealants are most valuable when applied soon after the permanent molars erupt - around age six for the first molars and twelve for the second. Sealing these teeth early, before decay has a chance to start, is what makes them so effective.
Sealants and Everyday Care
Sealants are a helpful extra, not a substitute for good habits. Children still need to brush twice a day with fluoride toothpaste, limit sugary snacking, and have regular check-ups. At those visits, the dentist checks the sealants are intact and tops them up if any have worn, so protection continues over the years.
Sealants at a Glance
| Question | Answer |
|---|---|
| Does it hurt? | No - no drilling or injection |
| How long does it take? | A few minutes per tooth |
| Which teeth? | Chewing surfaces of back molars |
| Best age? | As molars come through (~6 & 12) |
| Do they last? | Years - checked and topped up as needed |
⚠ Important: Sealants protect the grooved chewing surfaces only - not the sides of the teeth or the gaps between them. Daily brushing and flossing are still essential, and sealants complement them rather than replacing them.
