My dentist recommended Listerine Mouth Wash when I had to extract a tooth due to a bad cavity. With regular flossing and Listerine I have found the condition of my oral health improving. There are many flavored variants that you can choose from- my favorite one is the blue one. It leaves your mouth refreshed for hours. It has a nice minty taste. There are no bad smells at all. I have even tried it after eating garlic and I never suffer from bad breath. It is quite strong and may burn the mouth if you have sensitive teeth. Here, you should again visit a good dentist to get the ideal mouthwash for your needs!
