Importance of Saliva in Preventing Tooth Decay

Saliva is largely composed of water, but it also contains compounds known as salivary mucins. These compounds give saliva its slippery feel, but they also help keep teeth healthy. According to a recent study in “Allied and Environmental Microbiology,” salivary mucins suspend oral bacteria and limit their ability to adhere to teeth.

Streptococcus mutans, the bacterium responsible for cavities, lives naturally in the mouth. They form a community that is densely packed and secrete sticky substances that form a biofilm. When you eat, the bacteria release acids, and these acids erode the enamel on your teeth. Over time, this can lead to cavities. Current prevention tactics include dental sealants, which cover the chewing surfaces of teeth, and fluoride, which hardens the enamel to make it less penetrable.

This recent discovery may offer another option that allows dentists to use natural processes to combat cavities. Additionally, it underscores the importance of having adequate saliva flow. Patients with dry mouth due to medication use, smoking, or other factors may need to take additional steps to keep their mouth properly lubricated and comfortable. Adequate hydration, sugarless chewing gums, and prescription saliva replacement products can all be helpful. If you smoke, quitting can help protect your smile and your health.

To keep teeth their healthiest, patients should continue brushing and flossing after meals and getting professional cleanings at least twice a year.
