Dental Sealants.

Dental sealants are a thin protective resin flowed into the deep pits and grooves on the chewing surfaces of the back teeth — grooves that can be narrower than a single toothbrush bristle, where decay often starts simply because a brush cannot reach inside.

Think of it the way you already think about sealing a wood deck before the weather gets to it, or putting a screen protector on a new phone: a thin, clear layer placed over the most vulnerable surface before any damage begins — not after. It is one of the simplest, most cost-effective steps in preventive dentistry, and it is the same logic you apply to the things you protect every day.
