What are Dental Sealants?
Dental sealants are a thin coating of plastic material that is applied to the chewing surfaces of the back teeth (molars and premolars). These teeth have pits and grooves that are difficult to clean, and bacteria can easily accumulate in them, leading to cavities. Sealants protect these teeth from decay by sealing off the pits and grooves, making it easier to keep them clean.
The Indications for Dental Sealants
Dental sealants are indicated for a variety of reasons, including:
1. Children and Adolescents
Children and adolescents are the most common candidates for dental sealants. This is because their teeth are still developing, making them more prone to cavities. Sealants can be applied as soon as the permanent molars come in, and they can be re-applied as needed.
2. Adults with Deep Grooves
Adults who have deep grooves in their teeth may also benefit from sealants. Even though they may have been brushing and flossing regularly, it can be difficult to reach all the nooks and crannies in the back teeth. Sealants can seal off these areas, preventing bacteria from causing cavities.
3. Patients with a High Risk of Cavities
Patients who have a high risk of cavities, such as those with dry mouth, a history of cavities, or poor oral hygiene, may also benefit from dental sealants. Sealants can provide an additional layer of protection against decay.
Exceptions to Indications for Dental Sealants
Although dental sealants are beneficial for many patients, there are some exceptions to their use. Dental sealants are not indicated for:
1. Teeth with Existing Cavities
Sealants are not meant to be used on teeth that already have cavities. The decayed tooth structure must be removed, and a filling or crown should be placed before applying a sealant.
2. Teeth with Fillings or Crowns
Sealants cannot be applied to teeth that already have fillings or crowns. The sealant will not adhere properly to the surface and may cause problems with the existing restoration.
3. Patients with Allergies to Sealant Materials
Patients who have allergies to the materials used in dental sealants should not have them applied. The dentist will use an alternative treatment option to protect their teeth.
The Benefits of Dental Sealants
Dental sealants offer many benefits, including:
1. Protection against Cavities
Sealants provide a barrier against cavities, preventing bacteria from accessing the tooth surface.
2. Cost-Effective
Sealants are a cost-effective way to prevent cavities. They are much less expensive than fillings or crowns.
3. Easy to Apply
Sealants are easy to apply, taking only a few minutes to complete. They are painless and do not require any drilling or removal of tooth structure.
The Bottom Line
Dental sealants are a highly effective way to prevent cavities, especially for children and adolescents. However, they are not indicated for all patients, and there are some exceptions to their use. If you are interested in dental sealants, talk to your dentist to see if they are right for you.
