It is important to maintain good oral hygiene to treat gingivitis. Brush your teeth twice a day with fluoride toothpaste and use dental floss or interdental brushes to clean between your teeth. Avoid smoking and excessive use of alcohol, as they can worsen gingivitis. If gingivitis continues or worsens, it is advisable to consult a dentist who can, if necessary, perform a professional cleaning or prescribe appropriate treatments. Regular dental visits also help prevent the recurrence of gingivitis.
