Dental Sealants: Patient FAQs

April 10, 2023

Dental sealants are made of body-safe plastic polymers

Dental sealants can be one of the most effective routes of cavity protection for children, teenagers and adults. Sealants act as a thin plastic barrier, keeping bacteria and food debris out of tooth crevices and preventing cavities from forming. They are also placed to stop the earliest stages of decay rather than placing a filling. Sealants are painless to install and can provide years of lasting protection.


What are dental sealants made out of?

Dental sealants are made of body-safe plastic polymers. The material is in a liquid form, so it can be painted onto a tooth and then cured with a UV light until it is in a hardened state. The process only takes a few minutes for your dentist or hygienist to apply the sealant to each tooth.


Who needs dental sealants?

Dental sealants are often recommended for children because they are prone to cavities at such an early age. However, adults without decay or fillings in their molars can also benefit from them.


How long do sealants last?

Dental sealants are highly recommended in part because they can be applied once and offer some level of protection for several years. According o the CDC, sealants may protect against 80 percent of cavities for up to 24 months but offer around 50 percent protection for as long as four years. 


Will you be able to see the dental sealants?

Dental sealants are clear once cured. Therefore, they do not change the appearance of a tooth at all. In fact, most people would never know a dental sealant was in place unless they were told because the protective layer is so difficult to see. 


How well do dental sealants work?

Dental sealants can work exceptionally well. We often neglect good brushing and flossing habits, especially with the teeth further in the back of the mouth. The sealants protect the tooth from acidic, sugary foods that can contribute to decay when brushing habits may not be at their best. 


Are dental sealants safe?

Dental sealants are considered safe. The material used is safe for the body and the likelihood of the sealant coming off and causing problems is extremely low. Very rarely, someone may have a mild sensitivity to the materials used due to an allergy. However, any allergies will be discussed before treatment.  Are you looking for an easy way to lower your risk of cavities? Reach out to discuss dental sealants and schedule an appointment.
