The use of adult toothpaste can improve breath. Adult toothpaste usually contains bacteriostatic ingredients and fluoride, which can effectively clean bacteria and food residues in the mouth and reduce the generation of bad breath. In addition, some adult toothpastes also contain breath refreshing ingredients such as mint, which can make your breath more fresh. However, only using toothpaste can not completely solve the problem of bad breath. It is also necessary to pay attention to oral hygiene, brush teeth regularly, use dental floss and mouthwash, and maintain good eating habits and living habits to effectively improve breath.
