Dental sealants are thin, protective coatings made of plastic or other dental materials that are applied to the chewing surfaces of the back teeth (premolars and molars). Their primary purpose is to prevent tooth decay by creating a smooth, protective barrier over the natural grooves and fissures of the teeth where food particles and bacteria are likely to accumulate. Sealants are particularly effective in preventing cavities in children and teenagers but can be beneficial for adults as well.

The application of dental sealants is a quick, painless, and non-invasive procedure. First, the teeth are thoroughly cleaned and dried. An acidic solution is then applied to the chewing surfaces to roughen them up, helping the sealant bond effectively. After rinsing and drying the teeth again, the sealant is painted onto the tooth enamel, where it bonds directly and hardens. Sometimes a curing light is used to help the sealant harden.

Dental sealants can protect teeth from decay for many years, but they need to be checked for wear and chipping at regular dental visits. On average, sealants can last up to 10 years, but they may need reapplication or repair over time.

While sealants are commonly recommended for children and teenagers as soon as their permanent molars and premolars come in, adults without decay or fillings in their molars can also benefit from sealants. Sealants can be a protective measure for anyone who is at risk of dental caries.

Most people do not notice any difference in their teeth after sealant application. Sealants are incredibly thin and only fill the pits and grooves of molar teeth. They are designed to be smooth and comfortable, not affecting the way your teeth feel when you bite down.

Sealants are primarily used on healthy teeth without decay. However, in some cases, a dentist might decide to apply a sealant on a tooth that has early signs of decay, to prevent further damage. Sealants are not a substitute for fillings in teeth with cavities.

Dental sealants are safe and effective, with no significant side effects or risks. The materials used in sealants are biocompatible and approved for dental use. Allergies to sealant materials are rare, but it’s important to inform your dentist of any known allergies or sensitivities.

Studies have shown that dental sealants can reduce the risk of decay in molars by nearly 80%. They are highly effective as a preventive measure against cavities, especially in conjunction with good oral hygiene practices.

While sealants are an effective preventive measure, they do not replace the need for good oral hygiene practices. Regular brushing and flossing, along with professional dental cleanings and check-ups, are essential for maintaining overall oral health.

The cost of dental sealants can vary depending on factors like location, dental practice, and the number of teeth being sealed. Many dental insurance plans cover sealants for children and teenagers, recognizing them as a preventive measure. It’s advisable to check with your insurance provider and discuss the cost with your dental clinic.
