Pit & Fissure Sealants

What are Pit & Fissure Sealants?

Pit and fissure sealants are preventive dental treatments applied to the chewing surfaces of molars and premolars, where deep grooves can trap food and bacteria. These areas are harder to clean and more prone to cavities, making sealants an effective way to reduce decay risk.

A sealant is a thin resin coating painted onto the tooth surface, then hardened with a special light to create a smooth, protective barrier. The procedure is quick and painless. While commonly used for children with newly erupted permanent teeth, sealants are also beneficial for adults at higher risk of tooth decay.

Procedure of Pit and Fissure Sealants

1. Cleaning the Teeth

Before the sealant is applied, the teeth must be thoroughly cleaned and dried. The dentist or dental hygienist will use a dental handpiece or air polisher to remove any plaque and debris from the teeth.

2. Isolation of Teeth

The tooth is isolated to keep it dry during the application process. Cotton rolls or a dental dam may be used to keep saliva and other fluids from contaminating the tooth surface.

3. Acid Etching

A special etching gel is applied to the tooth surface for a few seconds to create a rough surface that the sealant can bond to. The gel is then rinsed off and the tooth is dried.

4. Sealant Application

The sealant material is applied to the chewing surface of the tooth using a brush or an applicator. The material is typically a type of resin that hardens when exposed to a curing light.

5. Curing

The sealant is cured by shining a special light on it for a few seconds. This causes the resin to harden and form a protective barrier over the tooth surface.

6. Checking the Bite

After the sealant is applied, the dentist or dental hygienist will check the patient’s bite to ensure that the sealant is not interfering with the way the teeth come together.

The entire procedure of applying sealants is relatively quick and painless, taking only a few minutes per tooth. Sealants can last for several years before they need to be reapplied.
Overall, they are a safe and effective way to prevent tooth decay in the back teeth. They are particularly useful for children and teenagers who may have difficulty cleaning their teeth properly, as well as for adults who are at higher risk for cavities. If you are interested in getting sealants for yourself or your child, talk to your dentist or dental hygienist to see if this treatment is right for you.

Benefits of Pit and Fissure Sealants

Protects vulnerable areas

Sealants cover deep grooves on chewing surfaces to prevent food and bacteria buildup, reducing decay risk in areas difficult to clean by brushing alone.

Prevents cavities

By sealing these vulnerable areas, they can prevent cavities from forming in the first place. This can save patients time and money on future dental treatments.

Safe and painless

Sealants provide a safe, pain-free dental solution. The coating is applied to the tooth’s surface and hardened with a special light, with no drilling or injections needed.

Long-lasting

They can last for several years with proper care. This means patients can enjoy the benefits of this preventive treatment for an extended period of time.

Suitable for all ages

Sealants suit patients of all ages—commonly recommended for children and teens at higher decay risk, yet equally beneficial for adults with deep tooth grooves.

How are pit and fissure sealants applied?

The process of applying sealants is quick and painless. First, the teeth are thoroughly cleaned and dried. Then, an acidic solution is applied to the chewing surfaces of the teeth to help the sealant bond to the enamel. After a few seconds, the acid is rinsed off and the teeth are dried again. Finally, the sealant material is applied to the grooves and crevices of the teeth and hardened with a special light.

How long do pit and fissure sealants last?

Pit and fissure sealants can last for several years, but they do require periodic monitoring and maintenance by a dentist.

How effective are pit and fissure sealants at preventing tooth decay?

Research has shown that pit and fissure sealants are highly effective at preventing tooth decay in the deep grooves and crevices of the teeth, especially when combined with good oral hygiene and regular dental check-ups.
