How to Use Dental Sealants to Prevent Tooth Decay

According to the National Institute of Health, tooth decay is the most common chronic illness in the United States, with millions of people affected by minor to severe cavities. This common oral health issue is why dentists recommend that children get dental sealants as a preventive measure. Continue reading to learn more about how dental sealants work to protect your child’s teeth from decay.

How tooth decay forms

The sugars in food and beverages combine with bacteria in the mouth, forming plaque, a sticky and clear coating that adheres to the teeth's surface. Plaque slowly accumulates along the gum line and persists if proper oral hygiene practices are neglected. To protect against plaque, it is important for children to brush their teeth twice a day for at least two minutes each time and to floss daily.

If plaque remains on the teeth for too long, it breaks down the minerals in the enamel, leading to dental decay. Cavities, also known as “tooth decay,” develop as holes inside the teeth. A dentist must remove the decay and restore the lost tooth structure with dental fillings.

Dental sealants can help your child avoid tooth decay

Dental sealants are an excellent method to maintain a child's oral health and prevent decay. Molars and premolars, which are more prone to decay, benefit from dental sealants. Molars have deeper grooves at the back of the mouth, making them hard to reach and more susceptible to cavities. According to the American Dental Association, dental sealants can reduce the risk of cavities by up to 80 percent.

By adhering to the teeth, dental sealants fill fissures and pits, protecting the child’s enamel against plaque and acidic substances. These areas can trap food particles, making it challenging for a toothbrush to clean. Dental sealants help prevent decay, leading to complex restorative procedures such as crowns and root canals. With proper care, dental sealants can last up to 10 years.

Consult your child’s dentist

While regular brushing and flossing can help prevent cavities, they do not provide a foolproof guarantee. If parents have concerns about tooth decay, it is important for them to consult a pediatric dentist regarding dental sealants and other preventive oral health measures. Early intervention is essential because even seemingly minor oral issues like tooth decay can cause irreversible damage in the future.
