How Long Do Dental Sealants Last?

Brushing and flossing are key to a healthy mouth, but some teeth are harder to clean thoroughly than others. Molars and premolars, for example, have deep pits and grooves where food particles and bacteria can stay, increasing the risk of decay.

As a popular pediatric dental treatment, sealants offer an easy protective solution. By applying a thin plastic coating to the chewing surfaces, they block out debris and bacteria, reducing the chance of cavities. So, what are sealants made of, and how long can you expect them to last? Let’s take a closer look.

What are Dental Sealants?

Dental sealants are thin, protective coatings applied to the chewing surfaces of teeth, usually the back teeth (molars and premolars). These teeth have deep grooves where food particles and bacteria can get trapped, leading to decay. 

Sealants fill in these grooves, making the surface smoother and easier to clean.

They are commonly recommended for children as soon as their permanent molars come in, usually around ages 6 and 12. However, adults can also benefit from sealants if they have deep grooves in their teeth that are hard to clean.

How Long Do Dental Sealants Normally Last?

Dental sealants normally last somewhere around 5 to 10 years. However, some can stay intact even longer with good oral care. The longevity of a sealant depends on:

• The kind of material used
• Oral hygiene habits
• Eating habits
• Teeth grinding (bruxism)

Regular dental check-ups are important for your dentist to check whether sealants are still intact or need to be reapplied.

Do Dental Sealants Need Replacement?

Yes, over time, sealants can wear down or chip. If a sealant is damaged, bacteria can get underneath it and cause decay. That’s why dentists check sealants during routine visits. If they notice any wear, they may recommend reapplying the sealant to keep the tooth protected.

Are Dental Sealants Only for Children?

While sealants are most commonly used for children, adults can also get them. Children benefit the most because their newly erupted permanent teeth are more prone to cavities. However, if an adult has deep grooves in their teeth and is at a higher risk for cavities, sealants can be a good preventive measure.

How to Make Dental Sealants Last Longer?

Taking care of sealants is easy and doesn’t require any special steps beyond good oral hygiene:

• Brush twice a day with a good quality fluoride toothpaste
• Floss daily to clean between teeth
• Avoid chewing on hard objects like ice or pens
• Visit the dentist regularly for cleanings and check-ups

Are Dental Sealants Safe?

Yes, dental sealants are safe and have been used for decades. They are made from materials that have been thoroughly tested and approved by dental associations. The process of applying sealants is quick, painless, and does not require drilling.

In a Nutshell

Dental sealants are a great way to protect teeth from decay, especially for children. They typically last 5 to 10 years, but with proper care, they can stay effective even longer.
