Brushing and flossing are the best ways to help prevent cavities, but it’s not always easy to clean every nook and cranny of your teeth – especially those back teeth you use to chew (called molars). Molars are rough, uneven and a favorite place for leftover food and cavity-causing bacteria to hide.
A sealant is a protective coating that is applied to the chewing surfaces of the back teeth, filling in the natural pits and grooves. This creates a barrier between food, plaque, acid, and these cavity prone areas. Four out of five cavities in children develop in children’s premolars and molars.
How do sealants work?
Think of them as raincoats for your teeth. When the cavity-causing bacteria that live in everyone’s mouth meet leftover food particles, they produce acids that can create holes in teeth. These holes are cavities. After sealant has been applied it keeps those bits of food out and stops bacteria and acid from settling on your teeth—just like a raincoat keeps you clean and dry during a storm.
When do the molars need to be sealed?
Children and adults can benefit from sealants, but the earlier you get them, the better. Your first molars appear around age 6, and second molars break through around age 12. Sealing these teeth as soon as they come through can keep them cavity-free from the start, which helps save time and money in the long run.
