Fissure sealants are a preventative dental treatment used to help protect teeth from decay. They are most commonly applied to the back teeth, where deep grooves can make thorough cleaning more difficult.

At East Coast Bays Dental, fissure sealants are used as part of a preventative approach to oral health. They are carefully assessed and, where appropriate, recommended to support tooth decay prevention, particularly for children and adolescents.

What are fissure sealants?

Fissure sealants, sometimes referred to as dental sealants, are a thin protective coating applied to the chewing surfaces of teeth. They flow into the natural grooves, known as fissures, and harden to form a protective barrier.

These grooves can trap food and bacteria, increasing the risk of decay. Sealants for teeth help reduce this risk by making the tooth surface easier to keep clean.

When might fissure sealants be recommended?

Fissure sealants may be recommended for children or teenagers when permanent back teeth first come through, as these teeth are more vulnerable to decay in the early years.

They may also be considered for adults with deep grooves in their teeth or a higher risk of tooth decay. Your dentist will assess tooth shape, oral hygiene, and decay risk before recommending sealants.

Sealants are not required for everyone, and their use is always based on individual clinical need.

What to expect during fissure sealant treatment

Applying fissure sealants is a quick and non-invasive procedure. The tooth is cleaned and prepared before the sealant material is applied and set in place.

Most of the time, no drilling or injections are required, and the process is generally comfortable. Once applied, sealants begin protecting the tooth straight away. Your dentist will check the sealant at routine visits to ensure it remains intact and effective.

Supporting tooth decay prevention

Fissure sealants work best when combined with good oral hygiene and regular dental check-ups. Brushing twice daily, cleaning between teeth, and attending routine examinations all help support long-term oral health.

Sealants do not replace brushing or flossing, but they can provide additional protection for teeth that are more prone to decay.
