Are Dental Sealants Harmful to the Teeth and Damage Them?

March 1, 2021

Dental sealants are universally used for safeguarding the teeth against tooth decay and cavities. Children are often recommended dental sealants because they are prone to the two problems mentioned above. Dental sealants for adults are also recommended if they do not have any issues with their teeth.

The significance of dental sealants is to protect against and prevent dental caries. Unfortunately, bonds are the most inadvertently misused product currently. When sealants are applied to the teeth, they have a shelf life of five to ten years, but it is essential to get them checked during regular dental exams. Dental sealants can chip and wear over time, and these occurrences lead to leakage. The leakage traps bacteria and food beneath, causing tooth decay.

When defining dental caries, one must understand that it is an upset in the balance between loss of materials or gain from the tooth’s surface. The lack of nutrients from our teeth develops from the millions of bacteria within our mouths from everyday consumption of foods and beverages, producing acids even as saliva and fluoride provide minerals to our teeth. When you regularly have fermentable carbohydrates and maintain poor oral hygiene with insufficient fluoride intake, the mineral loss is significantly higher than its gain to cause tooth decay.

Dental sealants are a preventive measure minimally invasive to promote early intervention to prevent dental caries from forming in the premolars and molars’ pits and fissures. The pits and fissures are biting surfaces of the teeth and are highly susceptible to harboring plaque and bacteria. The dental sealant seals the holes and cracks to prevent plaque and bacteria buildup. It is not harmful or damaging to the teeth unless you have indications and contraindications for the sealants.

What Are the Indications and Contraindications of Sealants?

The indications for sealants include a history of dental caries, deep pits and fissures, poor oral hygiene, and enamel defects.
The contraindications for sealants are:

  • Shallow pits and fissures.
  • Restored teeth.
  • Good oral hygiene.
  • A high risk of dental caries.

What Happens When Dental Sealants Fail?

The efficacy of the sealant placement from the dentist office near you is the most critical step and reasoning for dental sealant failure. Eighty percent of tooth decay in young children in the pits and fissures and sealants has proven to be an essential tool for prevention.

Unfortunately, the success of the application depends on the placement. Children are recipients of dental sealants on most occasions and must have a clean and dry environment for the application to adhere to and function appropriately. Dentists confront challenges keeping a child fixed and still while the mouth area is clean and dry. The success of sealants is measured by the duration of time the bond remains on the teeth rather than tooth decay experienced in sealed and unsealed teeth. Pits and fissure sealants can prevent dental cavities only when they can retain themselves on the tooth surface.

Dentists use etching systems before applying dental sealants to increase retention. Unfortunately, improper application is the prime reason why dental sealants fail. Clinical evaluation of sealants indicates the sealants were fully retained on 50 percent of permanent teeth for four years. Ninety-five percent of placements were rated as having severe loss of the substance.

What Causes Dental Sealant Failure?

The primary because for dental sealant failure is improper placement because of salivary contamination. The failure has many reasons, including the dentist’s lack of experience, patient cooperation, and inadequate quantities of sealant material used.

Failure of the sealant material over time allows bacteria to leak in to release acids that erode the enamel. Beneath the sealant, the tooth color changes to brown and dark brown and expands over time until it reaches the pulp of the tooth, causing pain besides the need for extensive treatments, including Pulpotomy.

Dental sealants are not permanent applications and last for approximately five years. They are physical barriers on the tooth’s surface. If placed inappropriately, they can lead to the erosion of the enamel. Sealants can wear off from regular wear and tear on the occlusal surfaces and chip away. The problem becomes formidable when the bond wearers begin harboring bacteria underneath, causing decay.

Dental sealants are a preventive measure against tooth decay, but their failure rate is significantly high. However, they are worth the risk because they don’t allow damages to occur on your teeth. So long as the recipient visits an experienced dentist for the application and cooperates with the professional entirely, patients can benefit from having a healthy mouth.
