Fissure Sealants
The chewing surfaces of your back teeth (molars and premolars) contain natural grooves and pits, known as fissures.
Care that starts with you.
Overview
What you should know
These areas can be deep and narrow enough that a toothbrush bristle can't fully clean them, making them particularly vulnerable to decay. Fissure sealants are a thin, protective coating applied to these surfaces, acting as a barrier against plaque and food particles.
At Footscray Dental Studio, fissure sealants form part of our preventive approach, particularly for children as their adult molars come through.
What's Involved
Applying a fissure sealant is a quick, straightforward process:
- Cleaning and preparation — the tooth surface is thoroughly cleaned and dried.
- Application — a liquid sealant material is applied into the grooves of the tooth.
- Setting — the sealant is hardened, often using a special curing light, forming a smooth protective layer.
- Check — your dentist checks your bite to ensure the sealant feels comfortable.
No drilling or anaesthetic is required, making it a comfortable option, including for younger patients.
Benefits of Fissure Sealants
- Creates a protective barrier over hard-to-clean tooth surfaces
- Quick and painless to apply, with no drilling involved
- Can reduce the risk of decay in molars and premolars
- Particularly useful for children as their adult teeth emerge
- A cost-effective, preventive alternative to treating decay after it occurs
Who May Benefit Most
Fissure sealants are commonly recommended for:
- Children, as their permanent molars erupt (generally around ages 6 and 12)
- Patients with deep grooves or pits in their back teeth
- Patients with a history of decay in molars or premolars
- Adults at higher risk of decay who haven't previously had sealants applied
Is this right for you?
Who It's Suitable For
Fissure sealants are commonly recommended for children as their adult molars come through, though they may also be suitable for adults at higher risk of decay in these areas. Your dentist will advise if sealants are appropriate for you or your child during an examination.
Caring for Sealed Teeth
Sealants support—but don't replace—good oral hygiene. Continued brushing, flossing and regular check-ups remain important, and your dentist will monitor the condition of sealants at future visits.
