Dentist Fissure Sealing: How It Helps Protect Teeth from Decay

Yoga Nathan • September 25, 2026

Keeping teeth healthy is not only about brushing and flossing. Some areas of the mouth are naturally harder to clean, especially the deep grooves found on the chewing surfaces of back teeth. This is where dentist fissure sealing can be useful.

At Weston Creek Dental Care, fissure sealants may be recommended as part of preventive dental care for children, teenagers, and some adults. They help protect vulnerable tooth surfaces and may reduce the risk of decay developing in difficult-to-clean areas.

What Is Dentist Fissure Sealing?

Fissure sealing is a preventive dental treatment that involves applying a thin protective coating to the grooves and pits of a tooth.

Molars and premolars often have deep natural grooves on their chewing surfaces. Food particles and bacteria can collect in these areas, and a toothbrush may not always reach them effectively.

A fissure sealant creates a smoother surface over these grooves, helping make the tooth easier to clean and reducing the chance of bacteria becoming trapped.

Why Are Fissure Sealants Used?

Fissure sealants are mainly used to help prevent tooth decay.

Even with good brushing habits, some people have deeper grooves in their teeth that are more likely to hold food and plaque. Sealants provide an extra layer of protection over these high-risk areas.

They are commonly recommended for newly erupted permanent molars in children, but adults with healthy, deep grooves may also benefit in some situations.

How Does the Fissure Sealing Procedure Work?

The process is usually simple and does not involve drilling when the tooth is healthy and free from decay.

The dentist first cleans and dries the tooth. A preparation solution may then be applied to help the sealant bond to the enamel. After this, the sealant material is placed into the grooves and hardened.

The treatment is usually completed within a short appointment.

Does Fissure Sealing Hurt?

Fissure sealing is generally a comfortable procedure.

Because the sealant is placed on the outer surface of the tooth, there is usually no need for injections or local anaesthetic when the tooth does not require other treatment.

Patients can normally return to their usual activities after the appointment.

What Does a Fissure Sealant Feel Like?

A new sealant may feel slightly different when you first bite down, but this sensation usually becomes less noticeable quickly.

Your dentist will check your bite after placement and make adjustments if required.

Who May Benefit from Fissure Sealants?

Fissure sealants are often recommended for children once their permanent back teeth have erupted.

Children can be more vulnerable to tooth decay while they are still developing strong brushing habits. Protecting deep grooves during this period can be helpful.

However, fissure sealing is not limited to children. Teenagers and adults may also be suitable candidates if they have deep grooves that are difficult to keep clean and no existing decay in those areas.

Fissure Sealants and Children's Dental Care

Permanent first molars usually appear during childhood. These teeth need to last for many years, making early preventive care particularly important.

Your dentist can assess the shape of the tooth, the risk of decay, oral hygiene habits, and previous dental history before recommending a sealant.

How Long Do Fissure Sealants Last?

Fissure sealants can remain in place for several years, but they are not permanent.

Normal chewing can gradually wear down the material. Regular dental check-ups allow the dentist to inspect the sealants and determine whether any areas need to be repaired or replaced.

Good oral hygiene is still important even when a sealant is present.

Can You Still Get Tooth Decay with a Sealant?

A sealant protects only the area where it has been placed. Other parts of the tooth can still develop decay if plaque is not properly controlled.

This means fissure sealing should be used alongside regular brushing, flossing, dental check-ups, professional cleaning, and healthy eating habits.

Fissure Sealing as Part of Preventive Dentistry

Fissure sealants work best as part of a wider preventive dental routine.

Regular check-ups allow your dental team to look for early changes in the teeth and gums. Fluoride, good home care, dietary habits, and professional cleaning can also help protect oral health.

Preventive care aims to reduce the likelihood of dental problems before they become more complicated.
