Gingivitis is an inflammation of the gums. This commonly occurs because of films of bacteria that accumulate on the teeth which is called plaque.  A person who has gingivitis will normally have red and puffy gums. Their gums will most likely bleed when they brush their teeth.      

Generally, gingivitis can be resolved with good oral hygiene habits, such as longer and more frequent brushing, and flossing. Some people may find that using an antiseptic mouthwash, alongside proper tooth brushing and flossing also helps.  People that have gingivitis may need to see a dentist more then just twice a year to make sure that dental habits are being maintain and for check ups. Since untreated, gingivitis can progress to periodontitis, which is more serious and can eventually lead to loss of teeth.
