How a Dental Sealant Can Keep Teeth Clean

Dental Sealants Santa Rosa, CA

Your dentist might recommend dental sealant if some of your teeth are vulnerable to decay. These restorations serve as a barrier that keeps food particles, bacteria, and acids out of the grooves of their biting surfaces.

Oral bacteria feed on the sugars in food particles stuck on teeth after meals, and they excrete acids that cause tooth decay. These acids eat away at the structures of teeth.

Dental sealants are varnish-like materials that are painted on teeth surfaces. They are made from composite resins like those used for dental bonding, but it comes in liquid form, allowing it to seep into the grooves of teeth. When exposed to ultraviolet light, the sealant hardens up, forming a barrier that protects teeth from decay for up to five years.

How dental sealant keeps your teeth clean

Tooth decay is one of the most common issues dentists deal with. Brushing twice daily and flossing once a day is an effective way to protect teeth against decay, but some teeth are easier to clean than others. For example, the molars in the back of the mouth are often the hardest to clean, and children, in particular, struggle with cleaning them.

That allows food particles to stick to them for longer periods, giving oral bacteria the fuel they need to make acids that damage teeth. A dental sealant closes up the grooves of a tooth’s biting surface, preventing food particles and bacteria from making contact with them. It also evens out the tooth’s biting surface, making it easier to clean.

The process

Applying dental sealants is a non-invasive process that does not cause the patient any pain. It often starts with the dentist examining the patient to determine if the teeth being treated have existing decay. Any issues detected are usually addressed before proceeding with sealants.

Here is what the procedure looks like:

  • The patient’s teeth are cleaned and dried to start the treatment
  • A gel that contains an etching solution as its main ingredient is applied to the teeth being treated to roughen them. This leads to a stronger bond with the sealant
  • The gel is rinsed off the patient’s teeth, and their teeth are dried
  • The sealant is then brushed onto the pits and grooves of the teeth being treated. It seeps into all the crevices on the biting surface, sealing them
  • The sealant is hardened with ultraviolet light to complete the process


Covering teeth with dental sealants gives them a protective shield that prevents debris, bacteria, and acids from getting into their pits and grooves. The sealant protects the patient’s teeth 24/7 for up to five years.

Dental sealants are not a replacement for good oral hygiene. Patients still need to protect their teeth by brushing and flossing regularly.
