Dental Sealants: What Are They and Are They Effective?

Dental Sealants: What Are They and Are They Effective?

September 1, 2021

Brushing and flossing are the primary preventive measures. However, decay may still develop, especially in children because they are prone to cavities. You, therefore, need other preventive measures like dental sealants near you to protect the teeth from decay and cavities.

Dental sealants are thin coatings, usually made of plastic, applied on the grooves of the teeth to shield them from bacterial attacks and decay. They are more suitable for the back teeth because the molars and premolars tend to trap food particles and increase the risk of decay.

Who Can Get the Dental Sealants?

Dental sealants in Dublin are often recommended for children as they are more at risk of cavities. However, adults can also get the coatings if they have healthy teeth free of decay or fillings. Teeth fillings are used to repair decay, and therefore it is not ideal to use sealants. A dentist near you may use dental crowns instead to protect the fillings and restore the function of the teeth.

Are They Effective?

The Center for Disease Control and Prevention recommends dental sealants for school-going children. It is reported that the sealants can prevent decay and cavities by around 80 percent in the first year. Furthermore, children who don’t have sealants are twice more likely to develop decay than those with coatings. However, the effectiveness will reduce as the years go by, and that is why you need to use the sealants with other preventive measures.

Are the Sealants Safe?

There are a few concerns about the BPA levels found in the plastic coatings. Bisphenol A is a toxic substance found in plastic, and it is reported to affect the nervous and the immune system. However, the ADA (American Dental Association) and the CDC report that the levels of the BPA in the sealants are negligible and do not cause any harm.

You may also opt to get the glass ionomer sealants as they don’t contain any BPA and release fluoride. But, these sealants are not as effective and durable as the plastic versions.

How Are the Dental Sealants Applied?

Applying dental sealants is a painless process that only takes a few minutes. Since it is a non-invasive treatment, local anesthesia is not used. The steps include:

  • Our dentist in Dublin will begin the process by thoroughly cleaning the teeth to be sealed.
  • Each tooth is dried up with an absorbent material or cotton, which also helps to keep the teeth dry.
  • An acid solution is applied to the grooves of the teeth to roughen them up and make it easy for the sealants to bond. The teeth are then cleaned and dried before the sealants are applied.
  • The dentist will paint the plastic coating on the tooth, and it bonds immediately. Sometimes, though, a curing light is used to help the sealants harden.

How Long Do the Sealants Last?

Sealants are applied to permanent teeth, and they can last up to a decade. However, they need to be checked regularly for any wear and tear. The sealants can develop tiny cracks and render them ineffective. If the dentist notices any problem, he may change the sealants where necessary or recommend other preventive measures.

Are the Dental Sealant Covered by Insurance?

Most of the dental insurance plans cover dental sealants for children below 17 years. If you want the sealants as an adult, you can use other payment methods. Consult our dental team on the cost of getting the sealants.

What Other Preventive Dental Treatments Can You Use

While they are effective, sealants work best when combined with other treatments like fluoride. Fluoride treatments are recommended for children and those people at risk of decay. Fluoride strengthens the enamel and reverses mild dental cavities. Getting regular dental assessments and cleaning can prevent cavities and gum disease. It also gives the dentist the chance to detect any dental problems on time.
