Sealants
Dental sealants as a preventive measure to protect your child's teeth from cavities and decay
What are Dental Sealants?
Dental sealants are thin, protective coatings applied to the chewing surfaces of the back teeth (molars and premolars). They are made of a plastic material that bonds to the tooth and creates a barrier that protects the enamel from plaque and acids that cause cavities.
How Sealants Work
The chewing surfaces of the back teeth have deep grooves and pits that can trap food particles and bacteria. Even with proper brushing and flossing, these areas can be difficult to clean thoroughly. Sealants fill in these grooves and create a smooth, easy-to-clean surface that prevents cavities from forming.
When Should Children Get Sealants?
Sealants are most effective when applied soon after the permanent molars erupt. The first permanent molars typically appear around age 6, and the second permanent molars appear around age 12. Applying sealants at these times provides maximum protection during the cavity-prone years.
The Sealant Application Process
- Cleaning: The tooth is thoroughly cleaned and dried
- Preparation: An acidic solution is applied to roughen the tooth surface
- Rinsing: The tooth is rinsed and dried again
- Application: The sealant material is painted onto the tooth
- Curing: A special light is used to harden the sealant
Benefits of Dental Sealants
- Prevent cavities in the chewing surfaces of back teeth
- Reduce the need for fillings and other dental treatments
- Save money on dental care in the long run
- Provide protection for several years
- Are painless and non-invasive
- Can be applied quickly during a regular dental visit
How Long Do Sealants Last?
Sealants can last for several years, but they may need to be reapplied over time. During regular dental check-ups, your dentist will examine the sealants and may recommend reapplication if they show signs of wear or damage. With proper care, sealants can provide protection for up to 10 years.
Caring for Sealants
Sealants require no special care beyond regular oral hygiene practices. Children should continue to brush twice daily with fluoride toothpaste and floss regularly. While sealants protect the chewing surfaces, they don't protect the sides of the teeth, so proper brushing and flossing are still essential.
Are Sealants Safe?
Yes, dental sealants are safe and have been used for decades. The materials used in sealants are biocompatible and have been extensively tested. The American Dental Association and the American Academy of Pediatric Dentistry both recommend sealants as an effective way to prevent cavities in children.
Who Should Get Sealants?
- Children and teenagers with newly erupted permanent molars
- Children at high risk for cavities
- Adults who have deep grooves in their molars
- Anyone who wants to prevent cavities in their back teeth
Cost and Insurance Coverage
Sealants are a cost-effective preventive treatment. Many dental insurance plans cover sealants for children, and the cost is typically much lower than treating cavities that could have been prevented. Even without insurance, sealants are an affordable investment in your child's oral health.
Important Note
Sealants are most effective when applied to healthy teeth without existing decay. Regular dental check-ups help ensure that sealants are applied at the optimal time and that any existing cavities are treated before sealant application.
