What Are Dental Sealants?
Dental sealants are thin, protective coatings applied to the chewing surfaces of the back teeth (molars) where cavities most often occur. The sealant quickly bonds into the depressions and grooves of the teeth, forming a protective shield over the enamel. The process is quick and painless and can be completed in a single visit.
How Do Dental Sealants Work?
The chewing surfaces of molars have deep grooves that can trap food and bacteria, making them more susceptible to cavities. Even with regular brushing, it is difficult to clean these grooves thoroughly. Dental sealants act as a barrier, sealing out food and plaque. Studies have shown that sealants can reduce the risk of decay by nearly 80% in molars, making them an effective preventive measure.
Who Should Get Dental Sealants?
Children and Teenagers:
Dental sealants are most commonly applied to children’s and teenagers’ permanent molars as soon as they erupt, which is around ages 6 and 12. This is when the risk of cavities is highest.
Adults Without Decay or Fillings in Molars:
Sealants can also be beneficial for adults who have healthy molars with deep grooves and are at a higher risk of developing cavities.
People with Special Needs or Those at Higher Risk of Tooth Decay:
Some individuals may have a higher risk of decay due to various factors, such as medical conditions or certain medications that cause dry mouth. Sealants can provide added protection.
Benefits of Dental Sealants
Painless and Quick Application:
Applying dental sealants is a non-invasive procedure that takes just a few minutes per tooth. There is no need for anesthesia or drilling.
Cost-Effective Preventive Measure:
Preventing cavities with sealants is much less expensive than treating cavities with fillings or other dental procedures.
Long-Lasting Protection:
Sealants can last up to 10 years with proper care. During your regular dental visits, your dentist will check the condition of the sealants and reapply them if necessary.
Reduces the Need for Future Dental Work:
By preventing cavities early, sealants can help avoid more extensive dental treatments in the future.
How Are Sealants Applied?
Cleaning the Teeth:
The teeth that are to be sealed are thoroughly cleaned.
Preparing the Teeth:
The chewing surfaces are then treated with a special gel that roughens them slightly, allowing the sealant to bond more effectively.
Applying the Sealant:
The sealant is painted onto the tooth enamel, where it bonds directly to the tooth and hardens. A curing light may be used to help harden the sealant.
