Chewing gum has a mixed reputation, but the sugar-free kind is one of the simplest habits you can add to protect your teeth between brushes.
It switches on your saliva
Saliva is your mouth’s natural defence. Chewing can increase its flow several times over, washing away food particles and neutralising the acids that bacteria produce after you eat. Less acid means less time for enamel to soften.
It helps enamel repair itself
Saliva carries calcium and phosphate. When acid levels drop, these minerals move back into the tooth surface in a process called remineralisation. Twenty minutes of chewing after a meal gives that repair a useful head start.
Choose the right gum
- Sugar-free only. Gum sweetened with sugar feeds the same bacteria you are trying to control.
- Look for xylitol. This sweetener cannot be used by decay-causing bacteria.
- Keep it short. Around 20 minutes is enough. Long sessions can tire the jaw.
When to skip it
If you have jaw joint pain, clicking, or braces with fixed brackets, gum may do more harm than good. Ask us at your next visit.
Gum is a helpful extra, not a replacement. Brushing twice a day with fluoride toothpaste and cleaning between your teeth still do the heavy lifting.
