Introduction to Dental Sealants

Dental sealants are one form of preventive dentistry. They are used to protect the upper chewing surfaces of the molar teeth from decay. These molar teeth have a rough surface that is useful for chewing food. Unfortunately, the grooves and pits of that rough chewing surfaces are prone to trapping food particles and bacteria. This makes them susceptible to cavities. Sealants are designed to prevent this problem. The sealant is a thin, plastic coating that covers the molar’s chewing surfaces. This prevents food and debris from getting stuck in the rough tooth surface, thus preventing problems with decay.

How Dental Sealants Are Applied.

The process of applying dental sealants is painless and fairly straightforward.

1. Teeth Cleaning: First, the teeth to be sealed are thoroughly cleaned to remove any plaque or food particles.
2. Tooth Preparation: The clean tooth surface is then treated with an acidic solution to roughen it slightly, which helps the sealant bond to the tooth.
3. Sealant Application: After the tooth is rinsed and dried, the sealant material is painted onto the tooth enamel.
4. Curing: A special light is often used to harden the sealant, making it durable and resistant to wear.
5. Once applied, sealants form a protective shield over the enamel of each treated tooth, preventing food and bacteria from getting stuck in the grooves and pits.

The Benefits of Dental Sealants

Decay Prevention

The primary benefit of dental sealants is their ability to prevent tooth decay. Studies have shown that sealants can reduce the risk of decay in molars by nearly 80%. The top surface of molar teeth often have tiny pits and shallow openings that retain food particles. These openings may be smaller than the bristles of a toothbrush, so they are very difficult to clean. Sealants will fill in the tiny openings in the tooth, greatly reducing decay. Yet they still leave the surface of the tooth sufficiently rough for adequate chewing.

Cost-Effective

Sealants are an effective cost-effective preventive measure. As is often the case, prevention is far better than cure. It is far better and less expensive to prevent tooth decay with sealants than it is to repair a damaged tooth.

Painless Procedure and Long Lasting.

The application of dental sealants is quick, easy, and painless, making it an ideal preventive measure for children and teenagers. Once applied, these sealants can last several years, after which they can be reapplied. Regular dental check-ups can help monitor their condition and ensure ongoing protection.

Safe and Effective

Dental sealants are safe for both children and adults. They are an effective barrier against cavities without posing any health risks. While they are most commonly associated with children and teenagers, they are beneficial for patients of all ages.

Who Should Consider Getting Dental Sealants

• Children and Teenagers: As soon as a child’s permanent molars and premolars come in, typically between the ages of 6 and 14, they are at the highest risk of cavities. Applying sealants during this period can protect these teeth throughout the cavity-prone years.
• Adults: Adults who have deep grooves or pits in their teeth that have not yet developed cavities can also benefit from sealants. This preventive measure can help maintain oral health and reduce the need for more extensive dental treatments.
• Patients with Specific Dental Conditions: Those with conditions such as dry mouth, which can increase the risk of tooth decay, may find sealants particularly beneficial.

FAQs About Dental Sealants

Are Dental Sealants noticeable?

Sealants are typically clear or tooth-coloured, they blend in with the natural colour of the tooth. They will not be noticeable when you talk or smile.

How Long Will My Dental Sealants Last?

Sealants may last up to 10 years. The dentist will check the sealants at your regular appointment to ensure they are intact and providing the necessary protection. Obviously, a younger patient will need new sealants when their adult teeth replace the baby teeth.

Do Sealants Replace Fluoride?

No, sealants do not replace fluoride. Both are part of a comprehensive approach to preventing cavities. Fluoride helps protect all tooth surfaces from decay and helps repair early decay.

Why are Sealants only used on Molar Teeth.

The sealants only work to protect a rough surface, such as the chewing surface on top of the molar teeth. They will not bond to a smooth surface, such as a front tooth. The other teeth tend to be easier to clean. Sealants protect the back molars, which are sometime tricky to clean.

Maintaining Sealants

Maintaining good oral hygiene is essential even with sealants. Here are some tips to ensure your sealants last as long as possible:

• Regular Dental Visits: Schedule regular check-ups and cleanings to monitor the condition of your sealants.
• Good Oral Hygiene Practices: Brush twice a day with fluoride toothpaste and floss daily to maintain overall oral health.
• Avoid Hard Foods: Chewing on hard objects like ice or pens can damage sealants, so it’s best to avoid these habits.
