Dental sealants are plastic coatings that offer a simple and effective way to protect your teeth from cavities. The dentist places the sealants directly on the tooth material.
Here is a bit of information about why dentists offer sealants and how they are applied.
Why Do You Need Dental Sealants?
The pits and fissures of the back teeth's chewing surfaces are very deep and narrow, which makes them hard to reach with a toothbrush. As a result, food and bacteria can get stuck in these areas and cause tooth decay over time. The decay can lead to pain, infection, and tooth loss.
Dental sealants create a barrier between the tooth enamel and the plaque that causes cavities. They prevent bacterial acids from accessing the vulnerable areas of the tooth and damaging the enamel.
Who Can Benefit From Dental Sealants?
Dental sealants are most commonly applied to the teeth of children and teenagers when the permanent molars and premolars erupt. The permanent back teeth are more prone to decay because they have deeper and more irregular pits and fissures. The best time to apply dental sealants is soon after the teeth present before they have had a chance to develop cavities.
Nonetheless, dental sealants are not only for kids. Adults can also benefit from sealant applications, especially if they have no fillings or decay in their back teeth. Young adults often have untreated cavities in their back teeth, so dental sealants can help them avoid future problems.
How Are Dental Sealants Applied?
The procedure for applying dental sealants is quick, painless, and non-invasive. Consequently, there is no need for anesthesia. Your dentist will:
- Clean the designated tooth surface and subsequently dry it.
- Apply an acid gel to roughen the tooth surface and help the sealant bond.
- Rinse and dry the tooth again.
- Paint the liquid sealant onto the tooth surface with a small brush.
- Harden the sealant with a special light or let it dry naturally.
The whole application process takes only a few minutes per tooth. The sealant forms a thin layer of plastic over the tooth surface, which will be invisible or slightly white in color. Additionally, the dental sealant will feel smooth when you run your tongue over it.
How Long Do Dental Sealants Last?
Dental sealants can last several years, depending on how well you care for them. If they do wear down or chip over time due to chewing or grinding, your dentist can reapply them.
