Can you catch gum disease when a person has bad breath?

Gum disease, also known as periodontal disease, isn't contagious and is caused by poor dental hygiene, tobacco smoking, and certain medical conditions. Bad breath (halitosis) can be a sign of gum disease, along with other symptoms such as bleeding gums, gum recession, painful chewing, and loose teeth. However, bad breath can have various causes, including poor dental hygiene, foods that cause an odor, and medical conditions. Consulting with a dentist is crucial to determine the underlying cause of bad breath and receive appropriate treatment.
