Maintaining oral and dental hygiene
Proper oral hygiene provides the basis for faster healing of the blister. Brush and floss regularly. This prevents the accumulation of bacteria and the exacerbation of inflammation. Use mild mouthwashes and toothpaste without irritating substances.

Licorice extract
Shirinbayan also has anti-inflammatory and antiviral properties and helps to relieve and accelerate the healing process of oral blisters.
