Primary prevention
Good oral hygiene and proper fitting of dentures reduce the incidence of angular cheilitis. A decrease in angular cheilitis was noted in patients ages 60 years and older who chewed gum containing xylitol or chlorhexidine acetate and xylitol.[20]
Secondary prevention
Xylitol gum or petroleum jelly are recommended for use in the lip folds to prevent maceration.[20]
