We often hear the phrase “everything in moderation”, but which foods are you eating in moderation? If you have a Coke every other day, that’s 39 grams of sugar with each intake. Sugar is one of the leading causes of tooth decay. In fact, certain harmful bacteria feed off sugar. These bacteria create acids which destroy the tooth enamel and also form cavities.

So before your next grocery, carefully take note of your food intake and consult this list to know which snacks and beverages you should avoid.


This one is fairly evident.  Candies are bad for your teeth in a number of ways: besides the obvious high sugar concentration, their hardness can actually trigger a dental emergency due to the risk you have of chipping a tooth.

The sticky candies are just as harmful; sticky foods tend to stay affixed to teeth for longer periods of time.

TIP: If you can’t resist sticky candy or the dried fruit you find in trail mix, be sure to rinse your mouth with water and brush and floss thoroughly.


Surprisingly, citrus foods and drinks have high acid concentrations. Too much acidic food intake can destroy the enamel, the layer over your tooth protecting it from plaque and acids. Your tooth enamel plays an important role in keeping your teeth from decaying. So try your best to retain healthy habits that will prevent your enamel from eroding.

TIP: Avoid adding lemon to your water.


These caffeinated drinks aren’t terrible for you, as long as you resist adding sugar. But the fact that most people dread hearing is that drinking coffee or tea frequently is likely to stain your teeth and also causes dry mouth.

TIP: Drink lots of water in between your caffeinated beverages!


Easier said than done, of course. Unfortunately, potato chips are one of the worst snacks for your teeth. Because they’re filled with starch, remnants tend to get trapped between your teeth.

TIP: Floss immediately after consumption in order to remove all the food particles that lead to plaque build-up.


Alcohol causes dry mouth and extreme dehydration. You’ve probably experienced these symptoms after a few drinks. If you drink excessively, you’ll find that over time, they produce less saliva to hydrate their mouth, which in turn can lead to tooth decay or gum disease.

TIP: Limit your alcohol consumption, but when you do drink, have large quantities of water in between glasses.


A funny thing to add to the list, but it’s true that many people have a habit of chewing on the ice cubes floating around in their drink. While ice doesn’t contain any sugar or other additives, its extremely hard surface can be terribly damaging to your teeth.

TIP: Instead of chewing, let your ice melt in your drink!
