Vaping has become popular in recent years, often viewed as a “healthier” alternative to smoking cigarettes. However, research suggests that vaping isn’t healthy at all—and may do extensive damage to your oral and overall health.

Here are a few common problems vaping can cause for your mouth.

1. Increased bacteria. A 2018 study revealed individuals who vaped had more bacteria in their mouth than those who didn’t. Excess bacteria is associated with tooth decay.
2. Inflamed gums. In 2016, researchers found e-cig use can trigger an inflammatory response from gum tissues.
3. Dry mouth. E-cigarette liquids like propylene glycol are known to cause dry mouth, which can lead to bad breath, decay and even sores.
