Things to Know About Using Dental Sealants For Cavity Prevention

When it comes to maintaining oral health and preventing cavities, dental sealants have become a valuable tool in the dentist's arsenal. These thin protective coatings have made a significant impact on cavity prevention, especially among children and teenagers. Dental sealants offer a non-invasive and cost-effective way to safeguard your teeth against decay. In this comprehensive guide, we'll delve into five essential things you should know about dental sealants. From understanding what they are to their benefits and the procedure itself, we'll equip you with the knowledge to make informed decisions about incorporating dental sealants into your oral care routine.

What Are Dental Sealants? 

Dental sealants are thin, protective coatings applied to the chewing surfaces of molars and premolars. These back teeth have grooves and fissures that can trap food particles and bacteria, making them susceptible to cavities. Sealants act as a barrier, sealing off these vulnerable areas and preventing the accumulation of harmful substances. Typically, they are made of a plastic resin material that bonds to the tooth's surface, creating a smooth, protective layer. Sealants are most commonly used on the permanent molars of children and teenagers, but adults can also benefit from them.

How Do Dental Sealants Work?

The key to dental sealants' effectiveness lies in their ability to create a physical barrier on the tooth's surface. After thorough cleaning and drying of the tooth, the dentist applies a special gel to prepare the tooth's surface for bonding. This gel is then rinsed off, and the tooth is dried again. Next, the sealant material is painted onto the tooth and is either left to harden naturally or cured using a special light. Once set, the sealant acts as a shield, preventing food particles, acids, and bacteria from settling into the grooves of the tooth.

Who Should Get Dental Sealants?

Dental sealants are most commonly recommended for children and teenagers, primarily because their newly erupted permanent molars are at the highest risk of developing cavities. However, adults who are prone to tooth decay and have deep grooves or fissures in their molars can also benefit from sealants. Your dentist will evaluate your dental history, oral hygiene habits, and the condition of your teeth to determine if you are a candidate for dental sealants. In many cases, sealants are applied as soon as the permanent molars come in, usually around the ages of 6 and 12.

Benefits of Dental Sealants 

The advantages of dental sealants extend beyond cavity prevention. Here are some key benefits:

Cavity Prevention: Dental sealants act as a physical barrier, sealing off the grooves and fissures on the chewing surfaces of teeth. This prevents food particles, bacteria, and acids from settling in these vulnerable areas, effectively reducing the risk of cavities. By creating a shield, sealants offer exceptional protection against tooth decay, especially on the back molars.

Cost-Effective Solution: Preventing cavities through sealants is a cost-effective approach to oral care. The expense of applying sealants is typically much lower than the cost of treating cavities and undergoing restorative procedures like fillings or crowns. It's an investment in long-term dental health that can save you money in the future.

Non-Invasive Procedure: Dental sealant application is a non-invasive and painless process. It requires no drilling or removal of tooth structure. This makes it suitable for individuals of all ages, including children, who may have dental anxiety or sensitivity.

Long-Lasting Protection: Once applied, dental sealants can last for several years, providing continuous protection against cavities. While they may wear down over time, they remain effective in reducing the risk of tooth decay. Regular dental check-ups allow dentists to monitor the condition of sealants and reapply them as needed.

Improved Overall Oral Health: Beyond cavity prevention, dental sealants contribute to better overall oral health. By preserving the integrity of the tooth's surface, they help maintain proper dental function and prevent the need for extensive restorative work. This translates to a healthier and more comfortable mouth.

The Application Process

Getting dental sealants is a straightforward and painless procedure. Here's what to expect:

Cleaning and Preparation

The first step in applying dental sealants is to clean and dry the tooth thoroughly. This ensures that the sealant will bond effectively to the tooth's surface. The dentist may use a dental instrument to remove any debris or plaque from the tooth's chewing surface.

Tooth Preparation

To enhance the sealant's adhesion, your dentist will apply a special gel to the tooth's surface. This gel roughens the enamel slightly, providing a better surface for the sealant to bond to. After a brief application, the dentist will rinse off the gel and dry the tooth again. 

Sealant Application

Once the tooth is properly prepared, the dentist applies the dental sealant material to the tooth's chewing surface. This material is typically a thin, plastic resin that flows into the grooves and fissures of the tooth. The dentist carefully paints the sealant onto the tooth, ensuring complete coverage of the vulnerable areas.

Curing (if necessary)

In some cases, dentists use a curing light to expedite the hardening of the sealant. This quick-curing process ensures that the sealant sets firmly and immediately, allowing you to resume normal activities without delay.


The final step involves an evaluation by the dentist to ensure that the sealant has bonded correctly to the tooth. They will check for any imperfections or gaps in the sealant and make any necessary adjustments. Once the application of sealant is successful, you can enjoy the protection it provides against cavities.


Dental sealants offer a simple yet highly effective way to prevent cavities and protect your oral health. Whether you're a child, a teenager, or an adult with susceptible teeth, the benefits of sealants extend to all. By creating a protective shield on your molars and premolars, sealants can save you from the discomfort and expense of treating cavities down the road. Regular dental check-ups are crucial to monitor the condition of your sealants and ensure they continue to provide optimal protection. As part of your oral care routine, consider discussing the potential benefits of dental sealants with your dentist. With this powerful tool in your arsenal, you can look forward to a healthier, cavity-free smile and long-term oral well-being.
