What are Dental Sealants?
Dental sealants are a type of protective coating applied to the chewing surfaces of the back teeth, that is the molars and premolars. Their purpose is to protect these teeth from harmful bacteria and acids that can cause tooth decay and cavities. The American Dental Association highly recommends dental sealants for children and adults as a preventive measure against tooth decay.
How Dental Sealants Work
Dental sealants are made of a plastic material that adheres to the tooth surface. Once applied, the sealant quickly hardens and forms a barrier over the tooth enamel. This barrier stops plaque and food particles from settling into the tiny grooves and pits on the tooth surface – an area where most cavities begin. By creating this protective shield, dental sealants can significantly reduce the risk of cavities.
The Application Process
The process of applying dental sealants is simple and pain-free. A dentist or dental hygienist first cleans the tooth surface thoroughly to remove any plaque or food particles. The next step is to dry and apply an acidic solution to the tooth surface, which roughens it lightly to help the sealant bond better to the tooth. Once the solution is rinsed off, the sealant is painted onto the tooth surface. In the final step, a special light is used to harden the sealant.
Who Should Get Dental Sealants?
While dental sealants are primarily recommended for children – especially those with a high risk of tooth decay – there is no age limit for getting sealants. Adults who have no fillings or decay in their molars can also benefit from dental sealants. Remember, the key purpose of dental sealants is to act as a preventive measure against tooth decay. Therefore, they are a beneficial dental treatment for all age groups.
Importance of Regular Dental Cleaning
Besides dental sealants, regular dental cleaning plays a critical role in maintaining good oral health. Dental cleaning by a professional helps remove plaque and tartar that brushing at home may miss. It also helps identify any early signs of dental diseases, allowing for timely intervention and treatment.
Pros and Cons of Dental Sealants
Pros
Dental sealants are effective at preventing cavities – they reduce the risk of decay by nearly 80% in molars. They are quick and easy to apply, and the process is entirely painless. Sealants are also cost-effective, especially when compared to the cost of treating cavities.
Cons
One of the potential downsides is that dental sealants only protect the tooth surfaces where they have been applied, and not the areas between teeth. Hence, regular brushing, flossing, and dental cleaning is still essential. Occasionally, sealants may also peel off and may require re-application.
The Bottom Line
Whether you are an adult looking to protect your teeth, or a parent wanting to ensure the dental health of your children, dental sealants are an excellent way to prevent tooth decay. Coupled with routine dental cleaning, a balanced diet, and regular dental visits, dental sealants can help maintain your oral health in the long run.
