Dental Sealants in Lehi, Utah

What Dental Sealants Are

Dental Sealants are a preventive dental treatment used to protect the chewing surfaces of teeth that are most susceptible to cavities. These surfaces contain natural pits and fissures that are deeper than they appear and are difficult to clean thoroughly with brushing alone. Dental Sealants physically seal these grooves so bacteria and food debris cannot accumulate and initiate decay.

Why Dental Sealants Are Used Instead of “Watching and Waiting”

Cavities on chewing surfaces often begin below the visible enamel surface, meaning damage can occur before it is detectable on an exam. Dental Sealants are used when the enamel is still intact but anatomically vulnerable. Once decay has started within a groove, sealing is no longer appropriate and restorative treatment is required instead. This is why Dental Sealants are preventive, not corrective.

Teeth Commonly Considered for Dental Sealants

Not all teeth benefit equally from Dental Sealants. Dentists assess individual teeth rather than applying sealants universally.

First permanent molars

These erupt early and account for a large percentage of childhood cavities due to deep fissures and early chewing use.

Second permanent molars

These erupt later and are often sealed shortly after eruption if fissure anatomy is pronounced.

Certain premolars

Some premolars have fissures deep enough to retain plaque and may benefit from sealing in higher-risk patients.

Select primary teeth

In children with elevated cavity risk, some baby teeth with deep anatomy may be sealed to prevent early decay.

How Dentists Decide Whether Dental Sealants Are Appropriate

Dental Sealants are recommended only after evaluating whether sealing will actually provide protection for a specific tooth.

  1. The tooth must be fully erupted so the chewing surface is accessible
  2. The fissure anatomy must be deep enough to retain plaque
  3. The enamel must be intact with no evidence of decay
  4. The tooth must be capable of staying dry during placement

If these conditions are not met, Dental Sealants are not appropriate for that tooth.

Dental Sealants Application Process

Dental Sealants are placed using a conservative clinical procedure that does not remove tooth structure.


  1. The tooth surface is cleaned to remove plaque and debris
  2. The enamel is conditioned to allow proper bonding
  3. The Dental Sealant material is placed into the pits and fissures
  4. The material is cured to harden and secure it
  5. The bite is evaluated to confirm normal chewing function

The procedure does not involve drilling, injections, or enamel removal.

Tooth Anatomy That Makes Dental Sealants Effective

Dental Sealants are indicated based on tooth structure, not age or appearance. Molars and some premolars erupt with fissures that narrow toward the base, creating protected spaces where bacteria thrive. These fissures may extend deep into the enamel without being visibly stained or damaged. Dental Sealants are effective because they occupy this space completely, eliminating the environment necessary for decay to begin.

How Dental Sealants Are Maintained Over Time

Dental Sealants are durable but subject to wear from chewing and grinding. During routine dental visits, dentists evaluate whether the sealant remains intact and protective. If a sealant becomes partially worn or lost, it can be repaired or replaced to maintain effectiveness. Sealants do not require special care beyond normal oral hygiene.

When Dental Sealants Are Not Recommended

Dental Sealants are not beneficial for teeth with shallow anatomy, existing decay, or very low cavity risk. Teeth that cannot be adequately isolated from moisture during placement are also not suitable. In these cases, alternative preventive strategies may be more appropriate.

Frequently Asked Questions

  • Can Dental Sealants trap decay underneath?

    No. Dental Sealants are only placed on teeth with intact enamel and no decay.

  • Can Dental Sealants be reapplied if they wear down?

    Yes. Worn or partially lost Dental Sealants can be repaired or replaced.

  • Are Dental Sealants only for children?
