Dental Sealants – Extra Protection for Your Back Teeth

Dental sealants are a preventive marvel, thin, protective coatings applied to the chewing surfaces of premolars and molars. These teeth have fissures and pits that are hard to keep clean, making them prime spots for decay. Sealants fill in these grooves, creating a smooth surface that is easier to brush and less prone to plaque build-up. Commonly offered to children as soon as their permanent molars appear, dental sealants are also beneficial for adults at risk of decay, helping preserve your smile for years to come.

What exactly are dental sealants, and how do they prevent tooth decay?
Dental sealants, also known as pit and fissure sealants, are either resin or glass ionomer-based coatings applied to the back teeth’s biting surfaces. They act as a physical barrier, covering the grooves and pits where food and bacteria can hide. This smooth, protective seal helps prevent decay in those hard-to-reach areas by keeping out plaque and enhancing cleanability with your toothbrush.

Who benefits most from sealants, and can adults get them too?
Sealants are most often recommended for children and teenagers when their permanent molars emerge (typically between ages 6 to 14), as these teeth are particularly cavity-prone. However, adults with deep grooves in their molars or a history of decay may also benefit. Sealants offer added protection and are suitable for anyone at a higher risk of developing cavities, regardless of age.

What does the treatment involve? Is it painful or time-consuming?
Not at all! Sealant application is simple, painless, and quick. First, your dentist or hygienist cleans and dries the tooth, then applies a special solution to help the sealant bond. The liquid sealant is painted onto the grooves and hardened with a curing light. The process usually takes just a few minutes per tooth and requires no drilling or anaesthetic.

What are the types of sealants, and are there differences in effectiveness?
Sealants come in two main types: resin-based and glass ionomer cement (GIC). Resin-based sealants offer excellent retention and durability. Glass ionomer sealants release fluoride over time and bond well in slightly moist conditions, but may not last as long. Research shows both types are effective, though each suits different clinical scenarios and patient needs.

How long do dental sealants last, and how are they maintained?
Sealants can typically last between 5 to 10 years, depending on wear and care. During regular dental catch-ups, your dentist will assess your condition and may reapply or repair them if necessary. They remain effective only with good oral hygiene, so continue brushing twice daily with fluoride toothpaste and cleaning between your teeth.
