Fissure sealants are protective coatings that seal over the top of molar teeth to prevent decay from developing in the deep grooves where toothbrush bristles cannot reach.
It is a preventive treatment and recommended once the back permanent teeth have erupted.
How are they done?
The grooves of the teeth are cleaned and then the surface is etched using a special blue gel. The gel is washed off and the liquid sealant applied. Once the dentist has ensured that all the grooves have been filled with the liquid, the material is hardened using a bright light. There is no need to numb the teeth, as the process is quite passive. Just like painting nail polish on a fingernail.
Over time part of the sealant material may chip away through normal wear and tear. This is observed at regular check-ups. More sealant can be placed as required.
The bite may feel a little different initially however, this sensation is temporary.
Conscientious home care including brushing every morning and night, flossing once a day and regular six monthly check-ups to review the sealants.
