Gingivitis is a non-destructive type of periodontal disease, but untreated gingivitis can progress to periodontitis. This is more serious and can eventually lead to loss of teeth. Signs of gingivitis include red and puffy gums, that bleed easily when the person brushes their teeth. Gingivitis often resolves with good oral hygiene, such as longer and more frequent brushing, and flossing. In addition, an antiseptic mouthwash may help. In mild cases of gingivitis, patients may not even know they have it, because symptoms are mild. However, the condition should be taken seriously and addressed immediately.
