Fissure Sealants

Fissure Sealants Mt Gravatt

Dental sealants are thin coatings the team at Trembath Dental use to fill the deep grooves and pits in your teeth

These deep grooves can harbour bacteria and food debris and can be quite difficult to clean.

Fissure sealants are applied to the healthy chewing surfaces of the teeth to prevent dental issues like cavities and decay. Children are more vulnerable to tooth decay due to excessive sugar consumption, which is why fissure sealants serve as an effective preventative measure.


At Trembath Dental, we recommend that children have their first permanent molars sealed as soon as they erupt, which is usually around 6-7 years. The rest of the molars can be sealed as and when they appear, which is usually between 11-14 years. Rest assured, these sealants do not impair the chewing function of teeth in anyway.


Fissure-sealants are made of resin, glass ionomer base, or even a combination of the two. The popular, preferred choice of sealant is that made of resin. Fissure-sealants are thus durable and can last up to ten years if properly cared for.


The application of resin-made sealants is generally quick, straightforward and painless. Dr Trembath will:

  1. Clean the teeth to remove any debris stuck in and around the teeth. A small brush will be placed in a dental drill which uses a spinning action to clean the surface of the teeth;
  2. Condition the surface of the teeth that require sealant. Etching gel is then applied to the surface of the teeth for about 20 seconds to a minute, after which it is washed off. The acidic nature of the gel kills off any bacteria on the teeth and allows the sealant to adhere to the teeth;
  3. Wash the gel off the teeth and dry it using an air gun;
  4. Apply the fissure-sealant, which can be done by pouring it into the fissures of the teeth or painting it on using a brush;
  5. Cure the liquid sealant with a special light. After the sealant has hardened, it is ready to act as a barrier, protecting your child’s teeth from tooth decay and cavities.
