1) Crunch on ice and popcorn – Teeth are tough and made to last a lifetime eating a normal diet, but they do have a breaking point. Ice is tough – tough enough that glaciers carve mountains and an iceberg could peel open the Titanic. Chewing ice is a common habit; but even if this doesn’t cause a major break, it can lead to a network of tiny cracks that can develop serious problems as time goes on. Popcorn has its own dental dangers. Kernel husks can easily become wedged between teeth or under the gums causing irritation. Unpopped kernels can crack or break teeth.
DO & DON’T
2) Use a straw/don’t swish – The impact of sweet and/or acidic drinks can be cushioned by getting into the habit of drinking through a straw aimed toward the back of the mouth. Swishing a drink through the teeth, however, intensifies the effect of both sugars and acids.
3) Use water as a mouthwash – Water makes the perfect rinse to clear sugars and acids after eating or drinking.
DO 4) Be careful brushing – Brushing is recommended after every meal. However there’s an exception; if one has just consumed an acidic food or beverage, they should rinse with plain water to clear the mouth, and then wait at least a half-hour before brushing.
After the acid bath, tooth enamel is more vulnerable to damage. Waiting a while gives saliva a chance to remineralize the (enamel) so the brushing doesn’t worsen the damage.
5) Frequency – The longer food that promotes plaque bacteria stays in your mouth, the worse it is. It takes 20 minutes for the acid attack on your teeth to subside after eating . If what you are snacking on is sticky and clings to your teeth, it is longer. So it’s not necessarily the amount of sweets you eat, but how often you eat them. Having one jelly doughnut or piece of candy per hour will cause more damage than having 10 of them at the same time.
