Brushing and flossing are the best ways to prevent tooth decay, but cleaning every corner and gap of the teeth (especially the posterior teeth used for chewing (called molars)) is not always easy. Molars are rough and uneven, and are places where residual food and bacteria that cause tooth decay are hiding.

However, there is another safety net that can help keep your teeth clean. It is called sealant and is a thin protective coating (made of plastic or other dental materials) that can adhere to the chewing surface of your back teeth. They are not a substitute for brushing and flossing, but they can prevent tooth decay from forming and even prevent the early stages of tooth decay from becoming complete tooth decay.

In fact, sealants have been shown to reduce the risk of decay of molar molars by nearly 80%. This is especially important for children's dental health. In October 2016, the Centers for Disease Control released a report on the importance of sealants to school-age children, and only 43% of children 6-11 years of age knew about it. According to the CDC, "school-age children without sealants have almost three times as many cavities as children with sealants."


How does sealant work?
Think of them as raincoats for teeth. When the bacteria that cause tooth decay that live in everyone's mouth encounter residual food particles, they produce acids that can form holes in the teeth. These holes are cavities. After applying the sealant, it prevents food debris from entering and prevents bacteria and acids from depositing on the teeth, just like a raincoat can keep you clean and dry during a storm.

Who can get sealant?
Both children and adults can benefit from the sealant, but the sooner the sealant is obtained, the better. Your first molar appears around 6 years old and your second molar ruptures around 12 years old. Once the teeth run in and seal them, they can be protected from tooth decay from the beginning, which helps save time and money in the long run. Ask your dentist if the sealant is a good choice for you and your family.

How to use sealant?
This is a quick and easy process. Before placing the acidic gel on your teeth, your dentist will clean and dry your teeth. This gel will roughen the surface of your teeth, so a firm bond will form between your teeth and the sealant. After a few seconds, your dentist will rinse off the gel and dry your teeth again before applying the sealant to the groove of the teeth. Then, your dentist will use a special blue light to harden the sealant.

Can the sealant be placed on the cavity?
The sealant can be used in areas that decay early to prevent further damage to the teeth. Because some sealants are transparent, your dentist can pay close attention to the teeth to ensure that the sealant works properly.

are there any side effects?
Apart from possible allergies, the sealant has no known side effects.

Is there BPA in the sealant?
Yes, there is very little BPA in the sealant, but it is not enough to cause any harm to you or your loved ones. In fact, you only need to touch the receipt, use cosmetics or contact with dust, and you will be more exposed to BPA.

How long can the sealant last?
Sealants usually need to be used for several years before they can be reused. During your regular dental visit, your dentist will check the condition of the sealant and can reapply the sealant as needed.

Does the dental plan cover sealants?
Some plans do cover sealants, so please call your dental welfare company to find out what coverage you have.
