Sealants
When Dr. Jackie applies a dental sealant, she paints a plastic coating on top of your teeth. This makes your teeth smooth, getting rid of the rough edges, depressions, and grooves that are commonly found on teeth. It is essentially a protective coating against tooth decay and cavities.
The most common place to paint sealants is on back teeth since they are often irregular. They can also be very hard to reach, even if you brush your teeth regularly. Dr. Jackie uses it more on children though she does perform sealants on adults too!
