Permanent molars (around age 12) are the most likely to benefit from sealants, therefore it is optimal to apply the fissure sealant soon after the teeth have erupted, before they have a chance to decay.
Deep and stained fissure (left) is cleaned confirming no decay is present (centre) before the sealant is applied (right).
The procedure is relatively simple and quick and does not require drilling or the removal of any tooth structure. A sealant can last for as long as 5 to 10 years but should be checked at regular dental appointments to see if they require re-application. The use of fissure sealants can save time, money and the need for dental fillings.
