As a dentist with years of experience, I have witnessed the detrimental effects of tooth decay on my patients' oral health. It is a common issue that affects people of all ages and if left untreated, it can lead to serious dental problems such as cavities, gum disease, and even tooth loss. That's why it is crucial to take preventive measures to stop tooth decay from worsening. Dental sealants are a thin, plastic coating that is applied to the chewing surfaces of the back teeth (molars and premolars).
These teeth have deep grooves and pits that make them more susceptible to decay. The sealant acts as a barrier, protecting the teeth from bacteria and food particles that can cause cavities. The sealant is usually made of a clear or white resin material that is painted onto the teeth. It bonds quickly to the tooth surface and hardens into a protective layer. It is virtually invisible and does not affect the appearance or function of the teeth.
How Do Dental Sealants Help Prevent Tooth Decay?
The main purpose of dental sealants is to stop tooth decay.They do this in several ways:
- Sealing off vulnerable areas: As mentioned earlier, the back teeth have deep grooves and pits that are difficult to clean with regular brushing. These areas are prime spots for bacteria and food particles to get trapped, leading to decay. By sealing off these areas, dental sealants prevent bacteria from reaching the tooth surface.
- Smoothing out rough surfaces: The resin material used in dental sealants fills in any rough or uneven surfaces on the teeth, making it easier to clean them. This reduces the chances of plaque buildup and helps keep the teeth clean and healthy.
- Protecting against acids: When we eat or drink, the bacteria in our mouth produce acids that can erode the tooth enamel and cause decay.
Dental sealants act as a barrier, preventing these acids from reaching the tooth surface and causing damage.
Who Can Benefit from Dental Sealants?
Dental sealants are most commonly used in children and teenagers, as they are more prone to tooth decay due to their developing oral hygiene habits. However, adults can also benefit from sealants, especially if they have deep grooves and pits on their back teeth or a history of cavities. Sealants are typically applied as soon as the permanent molars and premolars erupt, usually between the ages of 6 and 12. However, they can also be applied to baby teeth if they have deep grooves and pits that put them at risk for decay.The Process of Applying Dental Sealants
The process of getting dental sealants is quick, painless, and non-invasive. It can be done during a routine dental visit and does not require any numbing or drilling. Here's what you can expect during the procedure:- Cleaning: The teeth that will receive sealants are thoroughly cleaned to remove any plaque or food particles.
- Drying: The teeth are then dried with an absorbent material to ensure that the sealant bonds properly.
- Etching: A special solution is applied to the tooth surface to roughen it up. This helps the sealant adhere better to the tooth.
- Application: The sealant is painted onto the tooth surface and allowed to bond for a few seconds.
- Hardening: A special light is used to harden the sealant, making it strong and durable.
Maintaining Dental Sealants
Dental sealants can last for several years with proper care.Here are some tips to help maintain your sealants and stop tooth decay from worsening:
- Practice good oral hygiene: Brush your teeth twice a day with fluoride toothpaste and floss daily. This will help keep your teeth clean and free of plaque and bacteria.
- Avoid hard or sticky foods: Chewing on hard objects or eating sticky foods can damage or dislodge the sealants. Try to avoid these types of foods, especially in the first few days after getting sealants.
- Visit your dentist regularly: Regular dental checkups are essential for maintaining good oral health. Your dentist will check on your sealants during these visits and make any necessary repairs or replacements.
In Conclusion
Dental sealants are a simple yet effective way to prevent tooth decay.They act as a protective barrier, sealing off vulnerable areas of the teeth and preventing bacteria and acids from causing damage. Getting sealants is a quick and painless process, and with proper care, they can last for several years.
