2. Gum works
If you’re not so keen on carrying your toothbrush wherever you go (who is?), sugar-free chewing gum is a great alternative. Gums that contain the sugar substitute xylitol in particular have been shown in studies to reduce cavities: xylitol fights cavity-causing bacteria and prevents the formation of plaque on teeth. The evidence is so strong that organizations such as the American Academy of Pediatric Dentistry have made statements supporting the use of xylitol gums.
