FISSURE SEALING

Fissure sealing is one of the most effective preventive procedures in dentistry. It protects the chewing teeth from caries by sealing the natural grooves in the enamel where food debris, plaque and bacteria collect. Dentists recommend this procedure both for children — right after their permanent teeth erupt — and for adults whose fissures are deep or hard to reach with regular brushing.

Fissure Sealing — Effective Caries Prevention

Fissure caries is one of the most common types of tooth decay. It develops where a toothbrush cannot reach and bacteria build up over the years. Fissure sealing blocks this path at an early stage — before the enamel starts to break down. It is simple, quick and much less expensive than any later treatment.

What Is Fissure Sealing

What Are Tooth Fissures

Fissures are the natural grooves and pits on the chewing surface of the teeth. They are part of the tooth’s anatomy and help grind food. The problem is that some fissures are so narrow that toothbrush bristles physically cannot clean them. This is exactly where plaque and bacteria accumulate, eventually leading to enamel damage.

Fissure Sealing — What the Procedure Involves

Fissure sealing means applying a special protective material — a sealant — to the chewing surface of the tooth. It fills the grooves, creates an even surface and prevents bacteria from coming into contact with the enamel. The procedure is purely preventive — it is performed on a healthy tooth to stop caries from developing.

Why Fissure Sealing Is Done

The main goal is to prevent fissure caries, one of the most common types of tooth decay. Sealing also helps preserve the integrity of the enamel during the first years after a tooth erupts, when it is not yet fully mineralized and is most vulnerable.

When Fissure Sealing Is Needed

Which Teeth Are Sealed Most Often

The procedure is most often performed on molars and premolars — the chewing teeth with a pronounced fissure pattern. They bear the greatest load when eating and have a complex surface that is difficult to clean thoroughly with a brush.

At What Age the Procedure Is Performed

The best time for sealing is within the first 1–2 years after a permanent tooth erupts. In children, this is usually at 6–7 years of age for the first molars and 11–13 years for the second molars. During this period, the enamel is not yet fully formed and the risk of caries is at its highest.

Do Adults Need Fissure Sealing

Yes, provided the tooth is healthy and the fissures are deep. The dentist assesses the condition of the enamel and decides whether the procedure is appropriate. If caries has already started, sealing is not performed and treatment is prescribed instead.

Fissure Sealing for Children

In pediatric dentistry, sealing is one of the key preventive methods. Children’s teeth are more prone to caries: the enamel is thinner, hygiene is often imperfect, and their diet contains more sugar. Sealing the fissures right after a tooth erupts significantly lowers the risk of decay throughout childhood.

The procedure is recommended for primary molars (usually at 3–4 years of age) and for permanent chewing teeth as soon as they appear. The earlier the dentist applies the sealant, the better the chance that the tooth will stay healthy without any intervention.

Parents often ask whether the procedure is painful for a child. Fissure sealing does not require anesthesia, drilling or any mechanical intervention in the tooth structure. The dentist simply treats the surface and applies the material — children tolerate it calmly, without stress or fear of the dentist.

Invasive and Non-Invasive Fissure Sealing

Non-Invasive Fissure Sealing

The non-invasive technique is used when the fissures are shallow, well defined and show no signs of damage. The dentist cleans and dries the tooth surface, applies an etching gel and fills the grooves with sealant. No dental drill is used. This is the gentlest version of the procedure.

Invasive Fissure Sealing

Invasive sealing is indicated when the fissures are very deep or early changes in the enamel are suspected. In this case, the dentist slightly widens the groove with an instrument to make sure there is no hidden caries and to ensure better adhesion of the sealant. The intervention is minimal and cannot be compared to caries treatment.

How the Methods Differ

The dentist chooses between the invasive and non-invasive technique based on the examination and, if necessary, an X-ray. Both methods are reliable — the only difference is the extent of tooth preparation.

How Fissure Sealing Is Performed

Preparing the Tooth

First, the dentist thoroughly cleans the chewing surface of plaque and food debris. Then a special gel is applied that lightly etches the enamel — this improves the bond between the material and the tooth surface. After that, the tooth is rinsed and carefully dried.

Applying the Sealant

The sealant is applied in liquid form and fills all the grooves and irregularities. The material is then cured with a special lamp, which hardens it in just a few seconds. Once it has set, the dentist checks the bite and adjusts the surface if needed.

How Long the Procedure Takes

The whole procedure takes 20 to 40 minutes, depending on the number of teeth. None of the stages cause pain or discomfort.

Fissure Sealing Materials

Which Sealants Are Used

Modern dentistry mainly uses composite and glass ionomer sealants. Composite sealants are mechanically stronger and stay transparent for a long time, which makes it easy to monitor the tooth. Glass ionomer sealants release fluoride, which further strengthens the enamel. The choice of material depends on the clinical situation and the patient’s age.

Are Dental Materials Safe

All sealants used at the clinic are certified and approved for use in both pediatric and adult dentistry. They are hypoallergenic and contain no components harmful to the body.

Benefits of Fissure Sealing

The main benefit of fissure sealing is reliable caries prevention without any intervention in the structure of a healthy tooth. The sealant physically blocks bacteria and food debris from reaching vulnerable areas of the enamel.

The procedure also reduces tooth sensitivity to hot and cold and makes daily hygiene easier — a smooth chewing surface is much easier to clean than deep grooves where plaque settles.

With proper care, a sealant keeps its protective properties for 3 to 5 years. This means a single preventive visit to the dentist can replace several rounds of caries treatment in the future.

Fissure Sealing Cost in Lviv

The cost of the procedure is calculated per tooth — this is standard practice in dentistry. The final price is determined after an examination by the dentist, who will assess the fissures and choose the appropriate technique — invasive or non-invasive.

The cost usually includes cleaning the tooth surface, applying the etching gel and the sealant, and curing it. If several teeth need sealing, this is discussed during the consultation — clinics sometimes offer better terms for a comprehensive treatment plan.

A Dentist’s Recommendation

Fissure sealing should be done as soon as the tooth has fully erupted — ideally within the first year. During this period, the enamel has not yet reached its full density, and the fissures are open to plaque and bacteria. The longer you wait, the higher the risk of caries becomes with every month. I recommend that parents do not wait for the first signs of decay, but come in for a preventive check-up right after a chewing tooth erupts — it takes one visit and keeps the tooth healthy for years to come.

Frequently Asked Questions

Is fissure sealing painful? No. The procedure is completely painless and does not require anesthesia. While the sealant is being applied, the patient may only feel a light touch from the instruments, but no pain.

How long does a sealant last? With regular dental check-ups and normal chewing load, a sealant lasts 3 to 5 years. After that, the dentist assesses the condition of the coating and renews it if necessary.

Does the procedure need to be repeated? Yes, a sealant gradually wears down. During routine check-ups, the dentist checks its integrity. If the coating is damaged in some areas, it is reapplied — this takes very little time.

Can adults have fissure sealing? Yes, if the tooth is healthy and the fissures are deep. There are no age restrictions. The procedure is equally effective for caries prevention in patients of any age.
