Are you obsessive about your teeth? If so, you probably don't do any of these things that can be ruining your pearly whites.

I recently was talking to a friend of mine who works at a grocery store. I'm not sure how accurate this is but he told me that teeth whitening products are one of the most popular items that are stolen from their store.

Instead of committing a felony, maybe you should consider stop doing these things that can be ruining your teeth.

Things every day that can ruin your teeth by eroding and staining the tooth enamel -- something that cannot be replaced. identified the six worst things we do, often not even realizing it, that ruin our teeth. From black coffee to red wine, find out the top 10 foods and drinks that are most likely to turn your pearly whites into mellow yellows.

When you eat a large meal in one sitting, your mouth produces a lot of saliva, which helps wash away the food particles that can cause tooth decay. But when you snack, you don't produce as much saliva so your teeth aren't being cleaned naturally. The worst snacks for your teeth are carb-rich, including chips, crackers and even bananas. These foods actually work with bacteria to begin the decay process that will eventually destroy teeth. The solution: Brush your teeth after eating a snack. It's even more important than brushing after meals.

Diet soda
If soda is sugar-free, it must be OK for your teeth, right? Wrong. The acids in diet drinks, including citric and phosphoric, damage the tooth enamel. If you consume a lot of diet soda, it means your teeth are continually under acid attack. That can lead to tooth erosion. The solution: Drink water immediately after you drink diet soda to neutralize the acid attack.

Birth control
The Pill works by tricking your body into thinking it's pregnant, which isn't good for your teeth. These hormones can lead to periodontal disease, an infection that occurs when your immune response can't compensate for the amount of bacteria in your mouth. The solution: See your dentist every three months for a cleaning, as opposed to the normal six-month interval.

Your toothbrush
Many people think the harder the bristles on a toothbrush, the better they must be, but it's just the opposite. Hard brushes can actually cause gums to recede, exposing the root of the tooth. The solution: Use a soft bush, which more effectively removes plaque and bacteria without hurting your teeth.

Tooth whitening is safe. What is not safe is doing it too often, since excessive whitening can damage not only your teeth, but also your gums. In addition, beware of the teeth whitening pop-up shops at your local mall. The staff is not necessarily trained or licensed in teeth whitening, and consumers have walked out with burned lips and gums. The solution: Be smart about whitening. If you have questions or concerns, ask your dentist for advice.
