Gum infection is the presence of a harmful and damaging infection in the mouth that causes inflammation and pain in gum and jaw. It is also known as gingivitis, which is the infection of the gum by bacteria which causes inflammation. However, if this condition is left unattended to, it worsens and progresses into a more serious infection known as periodontitis.
According to the American Dental Association, periodontitis and gingivitis are two major reasons why adults lose their teeth.  However, not all gingivitis end up as a periodontitis infection.  Gingivitis is caused by the buildup of bacteria in the plaque and this causes inflammation and swelling of the gums. While brushing, the gums bleed easily and get sore.
Gingivitis only progresses to periodontitis when the former is left untreated. Periodontitis causes the bone and inner layer of the gum to separate from the teeth and form holes. These small spaces formed between the teeth and gum then begin to hold in debris and other food excesses, which causes bacteria to grow, causing an infection in turn. As the disease worsens, most gum tissue and bone gets destroyed and the holes in the gum get deeper. The tooth then loosens and eventually removes completely.
Treatment and Prevention of Gum Infection
Good Oral Hygiene
This is both a preventative measure and a treatment. To practice good oral hygiene, brush regularly, at least twice a day, and also floss at least once a day. Mouthwashes are also good for the teeth. Do not stick to one toothbrush for more than three months. Use toothbrushes that would be gentle on the gum, and not those that would cause the gum to bleed.
If you are confused about what toothbrush, toothpaste and mouthwash to choose from, ask your dentist for suggestion while treating gum infections in the mouth.
