The Benefits of Fissure Sealants for Children and Adults

As dental professionals at My Local Dentists, serving families across Sydney, we are dedicated to helping patients of all ages achieve healthy, long-lasting smiles. One often-overlooked but highly effective preventive dental treatment is the use of fissure sealants. Designed to protect teeth from decay, fissure sealants offer a simple, pain-free solution for both children and adults. In this blog, we explore the numerous benefits of fissure sealants, answer common questions, and debunk myths to help you make informed decisions about your oral health.

What Are Fissure Sealants?

Fissure Sealants are thin, plastic coatings applied to the surfaces of the teeth that are grooved and creviced—primarily the sides and biting surfaces of the molars and premolars but sometimes even on the surfaces of the front teeth if they are grooved or pitted. Sometimes the teeth have grooves and pits that can easily trap food particles and bacteria, making them especially vulnerable to cavities. Sealants create a protective barrier that blocks out plaque and acids, significantly reducing the risk of tooth decay. Much like how school books have a plastic contact cover on books to protect the books and keep them clean, fissure sealants are designed to protect the teeth from plaque, germs and tooth decay and keep them clean.

Sealants are typically applied in a quick and painless procedure that does not usually require drilling or anaesthesia. The dentist cleans the tooth, applies an acidic gel to roughen the surface, rinses and dries the tooth, and then paints on the sealant, which is hardened using a special UV curing light.

Who Should Get Fissure Sealants

Who Should Get Fissure Sealants?

Children and Teenagers

Children between the ages of 6 and 14 are particularly susceptible to cavities in their molars. Applying Fissure Sealants soon after their permanent molars come in can protect these vulnerable teeth during the cavity-prone years. Not everyone’s teeth are the same but fissure sealants will be especially useful if the teeth are really grooved and creviced and easy to catch plaque and stains.

Adults

While sealants are often associated with children, adults can also benefit—especially those who are prone to decay, have deep grooves in their molars, or have not previously had cavities in those teeth. Preventive care isn’t age-specific, and many adults can turn to Fissure Sealants to protect their teeth and help them last longer.

High-Risk Individuals

Patients with certain medical conditions, such as dry mouth (xerostomia) or those undergoing orthodontic treatment, may also benefit from sealants as part of a comprehensive preventive care strategy.

Benefits of Fissure Sealants

Benefits of Fissure Sealants

1. Effective Cavity Prevention

According to the Centers for Disease Control and Prevention (CDC), sealants can reduce the risk of cavities in molars by nearly 80% in children and adolescents. By providing a physical barrier against plaque, food particles, and bacteria, sealants significantly lower the chance of decay.

2. Cost-Effective Preventive Measure

Preventing cavities before they occur can save money on more extensive treatments like fillings, root canals, and crowns. Fissure Sealants are a relatively inexpensive option, often covered by health insurance, especially for children.

3. Quick and Painless Application

The sealant procedure is straightforward, non-invasive, and typically completed in just one dental visit. This makes it ideal for children and individuals with dental anxiety.

4. Long-Lasting Protection

Fissure Sealants can last between 5 to 10 years with proper care, making them a durable and reliable solution. Regular dental checkups will help your dentist monitor and maintain the sealants.

5. Enhanced Oral Hygiene

By smoothing out the chewing surfaces of molars, sealants make it easier to brush and remove food particles. This promotes better overall oral hygiene, reducing the risk of other oral health issues.

6. Suitable for All Ages

Whether you’re 7 or 70, Fissure Sealants can play a vital role in your oral health strategy. They are especially useful for patients who are at a higher risk for decay or those with deep grooves in their teeth.

How Long Do Fissure Sealants Last?

Fissure Sealants can last anywhere from five to ten years, depending on several factors:

  • Oral Hygiene: Proper brushing and flossing extend the life of your sealants.
  • Diet: A diet high in sticky, sugary foods or an acidic diet can wear down the sealant faster.
  • Tooth Grinding (Bruxism): This can cause sealants to chip or break.
  • Chewing Habits: Chewing on hard objects like pens or ice can damage sealants.

During your routine check-ups at My Local Dentists, your dentist will inspect the condition of your sealants and reapply them if necessary to maintain optimal protection.

Common Myths About Fissure Sealants

Myth #1: “Sealants are only for kids.”

Truth: While children are the primary candidates, adults can also benefit from sealants, especially if they are cavity-prone or have not had previous decay.

Myth #2: “Sealants contain harmful chemicals.”

Truth: Fissure Sealants are safe and approved by dental associations worldwide. Some concerns have been raised about BPA in dental products, but the levels in sealants are extremely low and considered safe by the Australian Dental Association. Visit the ADA website on Fissure Sealants.

Myth #3: “Sealants are a money-making scheme.”

Truth: Sealants are a preventive treatment that saves money in the long run by avoiding more costly and invasive procedures. At My Local Dentists, we prioritise your health and recommend sealants only when they are in your best interest.
