At Friendly Family Dentistry, we continuously stress to our patients the importance of maintaining a proper oral hygiene routine. Most patients assume that preventing tooth decay is the reason we are so passionate about cleaning teeth properly. While this is absolutely true, maintaining good oral hygiene also helps to prevent other oral health issues that can cause a great deal of damage to your mouth. Gum disease is one of these issues. Gum disease, also known as periodontal disease, is a bacterial infection of the gum tissue.
