7. Watch what you’re eating
When we go on vacation, we often change our eating habits. We tend to indulge ourselves a lot more, says Dr. MacGregor. “I guess we can’t begrudge somebody some snacks and good times. But the frequency of sugar exposure is very important,” he says. Try to limit the number of times you treat yourself to sweets in a day. Each exposure will make a difference to the health of your teeth.
