The gingivitis can be treated by maintaining dental hygiene, brushing and flossing teeth regularly, periodical dental checkups/ cleaning by a dentist, rinsing mouth with anti-septic mouth rinse and fixing dental restorations. In addition lifestyle changes such as quitting smoking, avoiding alcohol and having a low sugar and well balanced diet will keep the gingivitis away from you.
The first step in your treatment of gingivitis is thorough cleaning your teeth which includes scaling wherein all traces of plaque and tartar are removed. For people having sensitive gums and high buildup up of tartar and plaque the cleaning process is very uncomfortable. In order to clear the bacteria you might be asked to use an antiseptic mouth rinse. You will also be taught the correct brushing and flossing techniques. You have to practice good oral hygiene for life so that your gum problems don't return.
