Chew sugar-free gum after meals

Chew sugar-free gum for about 20 minutes after eating as an optional adjunct to routine tooth cleaning.

At a glance

What we know: Sugar-free gum may be a useful oral-care adjunct, but caries findings are tentative and it does not replace fluoride brushing or interdental cleaning.
What’s uncertain: Caries findings are tentative and studies vary; the evidence does not establish xylitol as the uniquely effective ingredient.
First step: If gum suits you, choose a sugar-free product and chew for about 20 minutes after a meal.
Before you try it: Do not use gum instead of fluoride toothpaste, brushing, or cleaning between teeth. All precautions

Takeaway

A systematic review of 12 studies found a tentative reduction in caries increment with sugar-free gum, but the studies varied and were generally moderate in quality. The American Dental Association describes it as a possible adjunct to twice-daily fluoride brushing and daily cleaning between teeth, not a replacement. The evidence does not justify treating xylitol as the uniquely effective ingredient.

Practical steps and precautions

How to try it

If gum suits you, choose a sugar-free product and chew for about 20 minutes after a meal.
Use it only as an optional add-on to twice-daily fluoride-toothpaste brushing and daily cleaning between teeth.
Do not assume a xylitol product is required; the gum’s chewing action and saliva stimulation are part of the proposed rationale.

Precautions

Do not use gum instead of fluoride toothpaste, brushing, or cleaning between teeth.
Stop if chewing aggravates jaw pain, and choose a product labelled sugar-free rather than one containing sugar.
