Gingivitis, an early and mild form of gum disease, is the only stage of gum disease that's reversible, according to the American Dental Association's Mouth Healthy site. That means the sooner you detect and treat gingivitis symptoms, the quicker your mouth can return to normal.
Mayo Clinic explains that gingivitis occurs when plaque, a sticky substance made up of bacteria, builds on up the teeth and gums. Typical symptoms include gums that are red (instead of pink), bleed easily and are swollen. The gums can also feel tender and soft to the touch. The plaque hardens into tartar, and more plaque builds up on the tartar which then continues to irritate the gums. If you notice any of the above, it's in your best interest to act quickly to help your mouth heal.
