Dental Sealants at Oaks Dental (Fissure Sealants)

A simple, preventative treatment designed to shield your teeth from decay — before it ever has a chance to begin. 

Some areas of your teeth are naturally more vulnerable to cavities, especially the deep grooves found on the chewing surfaces of the back teeth. These grooves can be narrow, uneven, and extremely difficult to clean properly, even with attentive brushing. At Oaks Dental, we use dental sealants as a gentle, effective way to protect these grooves and support your long-term oral health.
Sealants are one of the easiest steps you can take to reduce your risk of needing dental treatment in the future. They are quick, painless, and ideal for both children and adults who want to take a preventative approach to their oral care.

What are fissure sealants?

Fissure sealants (sometimes called tooth sealants) are thin, tooth-coloured protective coatings that flow into the grooves of molars and premolars. These grooves, known as “fissures,” can be deep and narrow — so narrow that even toothbrush bristles cannot reach the bottom. When plaque and food accumulate in these areas, they can create ideal conditions for decay.

A fissure sealant acts like a protective barrier, shielding the tooth surface from bacteria and making the grooves smoother and easier to clean. Once applied and set, the sealant blends seamlessly with the tooth and feels completely natural.

Sealants are:

  • Non-invasive
  • Painless
  • Quick to apply
  • Long-lasting
  • Suitable for all ages

Most importantly, they help reduce the likelihood of developing cavities in the most cavity-prone areas of the mouth.

 

How do fissure sealants work?

Molars and premolars naturally erupt with tiny pits and grooves. Some are shallow, while others are extremely deep or V-shaped. When these grooves trap food and bacteria, the enamel becomes vulnerable.

Sealants help by:

  • Smoothing the chewing surfaces, making plaque easier to remove
  • Creating a physical barrier that blocks bacteria from settling in the grooves
  • Reducing the risk of decay, especially in newly erupted molars
  • Supporting long-term dental health, particularly in growing children

While brushing and flossing remain essential, sealants give these hard-to-clean areas an added layer of protection.

 

How do fissure sealants work?

We make the process comfortable and straightforward from start to finish. Here’s what a typical appointment looks like:

Thorough cleaning of the tooth

We start by removing plaque or debris from the grooves so the sealant can bond properly.

Tooth preparation

A gentle conditioning gel is applied to the chewing surface. This helps the sealant material adhere securely.

Rinsing and drying

The tooth is rinsed and dried carefully to ensure the surface is ready for the sealant.

Application of the sealant

The tooth-coloured liquid is brushed into the grooves, where it flows and settles seamlessly.

Hardening the sealant

A small curing light sets the material within seconds.
No drilling.
No needles.
No discomfort.

From start to finish, the entire process is quick and relaxed, making it ideal for patients of all ages — including young children or those who prefer simpler dental visits.

How long do dental sealants last?

Sealants generally last several years, depending on your bite, eating habits, and oral hygiene. During your routine check-ups at Oaks Dental, we check the condition of your sealants and can reapply or repair them if needed.

Maintaining good oral hygiene at home and attending regular check-ups will maximise their longevity.

Frequently Asked Questions

    Are sealants only for children?

    While children benefit greatly from sealants on newly erupted molars, adults with deep grooves or a history of cavities may also be good candidates.

    Do sealants replace fluoride treatments?

    No. Sealants protect the grooves of the teeth, while fluoride strengthens enamel surfaces. Together, they offer complementary protection.

    Will the sealant be noticeable?

    The material is tooth-coloured and blends naturally. Most people cannot see or feel it once applied.

    Can sealants wear down?

    Sealants can gradually wear over time, especially in people who grind their teeth. Regular check-ups allow us to monitor and repair them if needed.

    How soon can I eat after the appointment?

    You can eat right away. The material hardens instantly under the curing light.

    Are sealants safe for kids with new adult teeth?

    Yes. Sealants are commonly used to protect newly erupted molars, which are particularly vulnerable during the early years of development.
