While tooth enamel provides a natural defense, bacteria can easily accumulate in the deep pits and grooves of teeth. This can lead to decay and cavities, potentially requiring extensive and costly dental work. At MyDentist, we offer dental sealants as a proactive solution to safeguard your oral health.
Dental sealants are beneficial for everyone, but they are particularly recommended for children as their permanent teeth emerge. This added layer of protection can help keep children cavity-free throughout their school years. By preventing the need for costly restorative procedures, families can save money, and children can focus on their studies without the distraction of toothaches and dental appointments.

A dental sealant is a simple, non-invasive procedure where a clear or tooth-coloured acrylic coating is applied to the surface of a tooth. This effectively seals the deep grooves where decay is most likely to develop. Sealants are a cost-effective preventive measure, typically less than half the price of traditional fillings, and they do not require any anesthesia or drilling.
Sealants can last for several years, and studies show that the risk of developing a cavity on a sealed tooth is reduced by half within the first five years after application. However, sealants can wear down, chip, or fall out over time. That’s why we carefully check them during every routine cleaning appointment. If a sealant is damaged or lost, we will discuss the most appropriate course of action, which may include reapplying the sealant.
Applying a sealant is a quick and painless process. Typically applied to molars, the procedure begins with a thorough cleaning of the tooth’s chewing surface, ensuring all grooves are free of debris. The tooth surface may then be gently roughened to enhance the sealant’s adhesion. After a quick rinse and drying, the sealant is applied. Finally, the sealant is dried, and the procedure is complete!
In some high-risk cases, we may recommend applying sealants to a child’s primary teeth. Although temporary, these teeth play a crucial role in guiding permanent teeth into their correct positions. Premature loss of primary teeth due to decay can lead to misalignment as other teeth shift to fill the gaps. This can disrupt the proper eruption of permanent teeth. Sealants on at-risk primary teeth help ensure long-term dental health and a smooth transition to healthy adult teeth.
Combined with regular dental checkups, consistent at-home oral hygiene practices, and fluoride use, dental sealants are a vital tool in maintaining healthy, cavity-free teeth.
