Dental sealants are a type of protective coating applied to the chewing surfaces of permanent back teeth (premolars and molars) to help prevent tooth decay. They are most commonly used in children and teenagers, as they are effective in preventing cavities in the early stages.
The process of applying dental sealants is quick, painless, and non-invasive. Here's how it typically works:
Cleaning: The dentist or dental hygienist will clean the teeth thoroughly to remove any plaque and food debris.
Isolation: The teeth being sealed are isolated with cotton rolls or a dental dam to keep them dry during the procedure.
Etching: The chewing surfaces of the teeth are usually etched with an acidic solution or a gel to create a rough surface. This step helps the sealant adhere better to the tooth.
Application: The dentist or dental hygienist applies the dental sealant onto the prepared tooth surface. The sealant is a liquid or gel-like material that flows into the deep grooves and pits of the teeth.
Curing: Some dental sealants are self-curing, meaning they harden on their own. Others may require the use of a special curing light that helps to speed up the hardening process.
Once the dental sealant is in place and hardened, it forms a protective shield over the tooth's chewing surface. This barrier helps to prevent bacteria, plaque, and food particles from accumulating in the deep grooves and pits, reducing the risk of tooth decay.
Dental sealants can last for several years, but they need to be checked regularly during dental visits to ensure they are intact and functioning properly. If a sealant becomes damaged or worn down, it can be repaired or replaced as necessary.
It's worth noting that dental sealants are just one part of maintaining good oral hygiene. Regular brushing, flossing, and routine dental check-ups are also essential for maintaining optimal oral health.
