Almost 90% of Americans have some degree of decay in their teeth, according to the NIH.


Even with dedicated brushing and flossing, it can be difficult to clean the deep grooves and pits on molars. Dental sealants can help with this issue. Acting as a protective barrier, dental sealants are a proven and highly effective method for preventing tooth decay.


Are you curious about the advantages of dental sealant application and sealant effectiveness? Many people also ask, "Are dental sealants safe?" Read on to learn about dental protection methods in detail.

What Exactly Are Dental Sealants?

Dental sealants are thin coatings of plastic. Each one is applied to the chewing surfaces of one's back teeth. It mainly involves the premolars and molars.


Such areas are especially prone to cavities due to their uneven surfaces, which can easily trap food particles and plaque. Once applied, the sealant quickly hardens and creates a smooth, protective layer. It shields tooth enamel from harmful bacteria and acids.


Think of it as a tried and true shield for your teeth. While it doesn't replace brushing or flossing, it offers added protection in vulnerable spots.

What to Expect From Dental Sealant Application

The dental sealant application process is both quick and pain-free. It's often completed in one dental visit.


The following is what you can expect during your visit to SmileOn Dentistry:


  • Cleaning
  • Preparation
  • Application
  • Curing



The whole process tends to take no more than a few minutes per tooth and doesn't require any drilling or numbing. As such, it's an ideal choice for patients of all ages.

Are Dental Sealants Safe?

Yes, dental sealants are safe. You'll be relieved to know that the American Dental Association endorses them, especially for children and teens. The same is true of the Centers for Disease Control and Prevention.


There has been some concern in the past regarding the presence of BPA (bisphenol A) in sealant materials. However, the amount of BPA exposure from dental sealants is extremely low, far less than what a person would encounter from everyday items like plastic containers or even dust. The ADA maintains that dental sealants are a safe and effective treatment for cavity prevention.


At SmileOn Dentistry, we prioritize patient safety by using the highest quality, BPA-free sealant materials approved by the ADA.

Who Can Benefit from Dental Sealants?

While dental sealant application is most commonly associated with children and teenagers, adults can benefit too.


Ideal candidates include children from six to 14 years old. Sealants are most dependable when put on as soon as the permanent molars come up from the gums. Teens prone to cavities are also good candidates.


Cavity-prone adults are yet another group. If your back teeth have deep grooves or fissures, sealants can help protect those areas.


Don't forget about patients with early signs of decay. Sealants can sometimes be used to halt the progression of those cavities before they require fillings.


SmileOn Dentistry offers personalized evaluations to determine whether you or your child is a candidate for dental sealants.

Sealant Effectiveness

Sealant effectiveness has been extensively proven, and the reality of its benefits is impressive. Dental sealants shrink the risk of cavities in one's molars by a significant amount in the first two years after application. They continue to protect against cavities for up to four years, but at a less effective level.


When maintained properly, sealants can last much longer. By stopping food and bacteria from getting trapped in hard-to-clean grooves, they significantly reduce the likelihood of decay. It's true even for those who are diligent about their brushing and flossing habits.


At SmileOn Dentistry, we perform routine evaluations during checkups to ensure your sealants remain in optimal condition. Overall, it reinforces your smile's defense against cavities.

The Lifespan of Dental Sealants

It's true that sealants provide excellent cavity prevention. Still, they should be part of a comprehensive dental protection strategy, which includes:


  • Brushing twice daily with fluoride toothpaste
  • Day-to-day flossing
  • Fluoride treatments, especially for children and patients with weakened enamel
  • Routine dental exams and professional cleanings
  • A thoughtful diet that puts a limit on sugary and acidic foods


At SmileOn Dentistry, our holistic approach to oral care ensures you have every layer of protection necessary for a healthy, lasting smile.
