Dental sealant is a protective layer on the tooth’s grooves, which prevents germs and food from getting trapped inside these grooves. The prevention of tooth decay follows this.
The masticatory surface of a child’s posterior teeth usually has minor grooves. Because they are so thin, even if the teeth are well brushed, they are not easily cleaned, and bacteria and food get stuck in them.
The groove or fissure sealant is applied without anesthesia and cut in approximately 10 minutes. And it can provide perfect protection against subsequent caries. And prevent the pain, cost and complications of future tooth decay.
Dental sealants are usually colourless or the same colour as the teeth. But there are also types of grooves in blue, pink or other colours that can be identified for later follow-up.
It should be noted that the teeth that have been fissured with sealant should be examined every six months to correct part of the groove in case of fracture or paleness.
Usually, the best time to do dental sealant is after the tooth is fully grown and before it decays.
Because the first permanent Asian tooth grows at the age of 6, it is necessary to have a fissure sealant around 6-7. At this age, the child still lacks enough cooperation to complete proper oral hygiene. In addition, because the loss of baby teeth does not accompany the eruption of tooth six, many parents do not even notice the discharge.
The second permanent Asian tooth grows at the age of 11, and this is a good age to make grooves on the 7th tooth.
Fissure sealants and fluoride therapy, especially fluoride varnishes, are two crucial caries prevention treatments.
Sealants are used in cases where caries has not yet occurred in the tooth, or a very initial view of the onset of caries is seen. In these cases, with preventive treatment, we prevent the development of caries. However, if there is caries or the tooth is empty, caries and damaged tooth tissue must be removed first and then filled with restorative metal or tooth colour.
