Cavities are a common and uncomfortable tooth problem. They cause pain and can be quite expensive to repair. Prevention is the best approach to avoiding cavities, and dental sealants are an excellent choice.

How Cavities Form
A cavity is a part of a tooth that has suffered damage, resulting in openings and holes. Cavities occur due to poor brushing habits, consuming snacks and sweet drinks or by having a buildup of bacteria in the mouth. While they can happen to anyone, cavities are more common in older adults. If they are not properly treated, they become larger and may result in tooth loss.

How Dental Sealants Work
Sealants work by getting into cracks and grooves in the teeth that are difficult to reach through brushing. Made up of plastic resins, sealants form a hard, smooth cover that is less likely to store harmful bacteria and plaque. This makes it easier to keep the teeth clean and healthy.

When to Get Sealants
Sealants are normally put on children’s permanent teeth and can also be used on healthy adult teeth. The sealants will last from three to five years and can be reapplied as necessary to ensure optimal oral health.
