We have said this one before, and you have probably heard it repeatedly. However, sugar is one of the worst things you can eat for your teeth. It just might be the worst thing, short of battery acid. Nevertheless, the pH of some kinds of soda is not far from that of battery acid. Think of your mouth as a battlefield, and it is fighting to protect your entire body. When you eat sugar, you feed the enemy attacking your body, the bad bacteria. That harmful bacteria will feast on the sugar and proliferate inside your mouth until you end up with nasty cavities and the need for fillings.
Eating ice cubes seems harmless enough. You can get your cold fix without any of the sugar that you would typically find in ice cream and soda by munching down on some ice cubes. And let’s face it: some people are obsessed with ice. It might not be a full ice cube, of course. It seems as though soft drink cups filled with crushed ice will do the trick for those longing for that cold crunch. However, dentists say that eating ice cubes is pretty bad for your teeth. The habit may be a symptom of a medical issue, such as pica (eating things that are not usually considered foods and have no nutritional value). The ice can damage the nerves in your teeth and even lead to fractures and loss of enamel. Many people who eat ice do so because they are deficient in iron or because they struggle with anxiety.
Are you a nail-biter? If not, chances are good you know an individual who is one. It’s one thing to have a hangnail and want to correct it on the spot (if you don’t have clippers). However, you might even know someone who chews their nails down to the nubs, sometimes causing them to bleed. This bad habit is a big no-no, both for your nails and teeth. Your fingernails harbor more bacteria and viruses than you have ever heard of. What do you think happens to your mouth when you start using your teeth to bite them off? You bring all those nasty bacteria into it, setting yourself up for infection. To make things worse, your fingernails can both chip and crack your teeth and, when inside your mouth, cause abrasive damage that makes your mouth even more susceptible to infection. For people who have braces on their teeth, the potential for damage is even more significant. Go to the store, pay two dollars for a pair of nail clippers, and start clipping your nails like an adult.
