Sealants act as a protective barrier by filling and sealing the narrow pits and grooves on chewing surfaces where plaque and food get trapped, reducing the chances of caries in those hard-to-clean areas. They are most effective when placed soon after eruption of the first permanent molars, because these teeth have deep, irregular grooves that are highly prone to decay. If other teeth have susceptible pits and fissures and the child is at elevated caries risk, sealants can be placed there as well. They are not used to whiten teeth, nor do they replace fluoride varnish; instead, they complement fluoride by physically blocking bacterial invasion in vulnerable areas. In practice, after cleaning and isolating the tooth, you etch to create retention, apply the sealant, cure it, and then verify proper bite and retention at follow-up visits.
