Types of Dental Sealants
There are different types of dental sealants. Your dentist will choose the best one based on your teeth and your risk of developing cavities.
Resin-Based Sealants
These are the most common types of dental sealant. They are strong, long-lasting, and help protect the chewing surfaces of back teeth from cavities.
Glass Ionomer Sealants
These sealants slowly release fluoride to help protect teeth. They may be recommended for patients who have a higher risk of tooth decay.
Your dentist will recommend the type of dental sealant that is best for your oral health.
How Long Do Dental Sealants Last?
A common question is how long do dental sealants last. With proper oral hygiene and regular dental checkups, many sealants remain effective for 5 to 10 years. During routine examinations, your dentist will check each sealant for signs of wear or damage and repair or replace it if necessary to maintain protection.
Dental Sealants for Cavities
Dental sealants for cavities are designed to help prevent new cavities rather than treat existing tooth decay. If a cavity is already present, your dentist will recommend the appropriate restorative treatment, such as a dental filling, before considering a sealant for other healthy teeth. Early examinations help identify the best preventive approach for each patient.
Using Dental Sealants for Sensitive Teeth
Some patients ask whether a dental sealant for sensitive teeth is appropriate. If tooth sensitivity is caused by exposed grooves or early enamel wear without decay, a sealant may provide additional protection in selected cases. However, sensitivity can have many causes, including cavities, gum recession, or cracked teeth. Your dentist will determine the underlying cause before recommending treatment.
