Dental Sealants

The Preventative Power of Dental Sealants

To conquer the fear of cavities let us take a deep dive into dental sealants. When it comes to oral health, everyone wants the best possible care for their teeth. Regular dental check-ups and maintaining oral hygiene are undoubtedly essential, but what about those of us who are prone to cavities despite our best efforts? Genetics and tooth structure can put some of us at a higher risk of developing tooth decay. Enter dental sealants, an efficient solution to this problem.

Unraveling the Mystery of Dental Sealants

Introduced in the 1960s, dental sealants have proven to be a remarkably effective tool in the battle against cavities. Within the first two years post-application, these sealants have demonstrated impressive efficacy, reducing the occurrence of cavities by up to 80%. 

What Exactly Are Dental Sealants?

First and foremost, dental sealants are thin plastic coatings. Dentists apply them to the chewing surfaces of our teeth, especially the molars and premolars. In fact, their main purpose is to act as a protective barrier. Consequently, sealants smooth out our teeth’s surfaces and prevent food particles and bacteria from getting trapped in the nooks and crannies.

Who Can Benefit From Dental Sealants?

Dentists don’t restrict dental sealants by age, but they most commonly recommend them for children, especially as their permanent teeth start to emerge. However, adults with deep pits or fissures in their teeth can also benefit. Moreover, sometimes on rare occasions, even baby teeth might be deemed suitable candidates.

The procedure itself is straightforward and, most importantly, pain-free. After cleaning and drying the chewing surface of the tooth, they paint the sealant. They then use a special light to harden the sealant, ensuring a strong, smooth shield over the tooth.

Who Should Consider Dental Sealants?

Primarily, children and teenagers often get dental sealants. However, adults without prior dental issues like decay or fillings in their molars can also find this treatment useful. If you’re susceptible to decay, especially on the back teeth, think about sealants.

Generally, kids should receive sealants once their permanent molars and premolars emerge. This ensures protection during the most cavity-susceptible years, from age 6 to 14.

Some children might also benefit from sealants on their primary (baby) teeth, especially if those teeth have significant grooves. Baby teeth pave the way for permanent teeth, making their health paramount.

Popularity of Sealants

Sealants rank high among preventive dental treatments. In the U.S., about 42% of 6-11-year-olds and 48% of 12-19-year-olds have sealants on their permanent teeth.

No special preparations are required for sealants. Your dental professional will handle everything during a standard visit, starting with a thorough tooth cleaning.

  4. Fourth, teeth are rinsed and dried.
  5. Fifth, the sealant material is painted on the tooth enamel.
  6. Sixth, a curing light is used to harden the sealant.

Advantages and Drawbacks:

Let us dig down the what are the advantages and drawbacks of using dental sealants. 


Regular oral care might not reach every dental crevice. Sealants help by guarding these areas from cavity-causing elements like bacteria and plaque.


  1. Sealants typically last for around five years, necessitating replacements.
  2. They can’t be used on teeth with existing decay or fillings.
  3. Improper placement might trap bacteria, leading to cavities.

It’s wise to consult with your dentist about sealants’ suitability.

Post-Procedure Insights:

Basically, post-procedure insights will be dealing with recovery, durability, and dietary regulations.

1. Recovery:

Post-sealant placement, you can immediately resume regular activities.

2. Durability:

Indeed, dentists advise periodic replacements even though tooth sealants can last up to five years.

3. Dietary Recommendations:

While you can eat and drink immediately post-application, avoid extremely hard or sticky foods as they might damage the sealants. Moderate consumption is best.

When to Consult Your Dentist

Routine dental check-ups should occur at least biannually. This is the perfect time to discuss dental sealants. If you notice oral health changes like tooth or gum pain, it’s vital to see your dentist.

Are Sealants Essential?

The necessity of sealants varies. They can significantly decrease the risk of cavities, especially in children. 

For instance, kids aged 6-11 without sealants are thrice as likely to get cavities. Sealants are cost-effective and can prevent future invasive dental treatments. However, they’re unsuitable for those with fillings, crowns, or partially emerged teeth.

For a thorough understanding of sealants and to determine if they’re a fit for you or your child, consult your dental professional.

Tackling the Burning Questions

Many might wonder about the potential risks associated with dental sealants. One primary concern involves the potential for allergic reactions. It’s vital to discuss any allergies with your dentist before the procedure. 

The materials used, including plant/synthetic resins and glass ionomers, are of medical grade and generally safe. Additionally, although sealants contain trace amounts of BPA, the American Dental Association has found no evidence linking BPA in dental-sealants to any adverse health effects.

Furthermore, as for the longevity of dental sealants, they’re designed to last up to a decade. However, this duration can vary based on personal habits and the natural wear and tear our teeth undergo. Over time, sealant for teeth might come loose or fall off, but regular dental visits can address such issues promptly.

There’s also a distinction between dental-sealants and fillings. Additionally, while sealants prevent damage, fillings restore teeth that already have damage.

Curious about whether dental sealants are the right choice for you?

 It’s worth bringing up during your next dental check-up. Dental professionals can offer guidance tailored to individual needs, whether those are cosmetic, preventive, or restorative.

The Wayforward:

In essence, sealant for teeth might be the protective measure you’ve been searching for. They provide a reliable defense against cavities, ensuring that your smile remains as radiant and healthy as ever. 

A note from Bakery Hill Dental Clinic

Dental sealants function similarly to raincoats for your teeth. Sealants protect your teeth from disease-causing microorganisms in the same way that a raincoat protects you from the weather. Sealants aren’t perfect, but they can lower your risk of cavities greatly, providing you with the best opportunity for healthy teeth and gums.
