“What is the best treatment for gingivitis?”

Hello! Regular dental check ups and cleaning would be the first step to get an assessment. There are many different recommendations based on your situation.Thanks

The best treatment for gingivitis is to get a thorough cleaning probably by a registered dental hygienist. Brushing and flossing will help but any accumulation of plaque and calculus below the gum tissue needs a professional to remove completely.

Have your teeth professionally cleaned. A cleaning by your hygienist is the first big step in the treatment of gingivitis. Your hygienist can remove significantly more plaque build-up than you can remove on your own. Hygienists and dentists are also specifically trained to identify the early signs and symptoms of gingivitis to help you get ahead of any issues.
Ask your dentist or hygienist if you’re brushing and flossing properly
