Oral probiotics are designed to support a healthy balance of bacteria in the mouth. Many people explore them for fresher breath, gum comfort, and overall oral wellness. This guide explains what to look for so you can choose wisely and avoid hype. Probiotics work best alongside proper hygiene, as discussed in our guide on how to improve gum health naturally.
