Dental sealant isn't a necessary cavity preventing treatment for all children, dental experts say. It doesn't need to be applied to all back teeth. And it can't be applied on a smooth surface, so sealant won't prevent cavities from forming between teeth, even if the surface of the teeth have been sealed.
