What Is the Connection Between Molars, Cavities, and Dental Sealants?

Posted .

Today’s blog is going to look at the connection between your molars, cavities, and dental sealants. Taking care of your teeth is essential for the ones you want to keep. This is especially challenging for the teeth in the back which are hard to reach.


These molars are more susceptible to cavities because their chewing surfaces have indentations that let bacteria and food particles hide in. Because of this, the acids they release can erode the molar’s enamel. This creates small holes that allow the acid to attack the dentin and tooth pulp, which damages the tooth from within.


This is where dental sealants come in. As they coat the molar’s top surface to seal in the tooth and keep out cavity-causing plaque. Having a sealant treatment is both quick and painless and is done on primary and secondary molars when necessary. In just a few steps, your molars can be fortified against decay. Let’s take a look:


– The tooth’s surface is cleaned with a paste and rotating brush.

– The tooth is rinsed with water and thoroughly dried.

– An acidic solution is applied to the grooves of the molar for several seconds to create a rough surface for the sealant to adhere to.

– Once the tooth is dried, the sealant is applied to the tooth.

– Depending on the sealant material, it may be hardened using a light.


Once the sealant hardens, it is a hard coating that you can chew on to help keep cavities out.
