5. Aiming for the whitest smile of all
Using over-the-counter white smile kits can do more harm than good. Katz says that aiming for the whitest smile no matter the cost can eventually lead to enamel loss, resulting in permanent tooth sensitivity. It’s best to ask your dentist about the product you want to use in order to whiten your teeth.
However, most dentists recommend natural whiteners like strawberries and cauliflower.
6. Chewing pencils
Yep, it happens often than you think… Chewing pencils can lead to stress fractures in your teeth. So, instead of chewing a pencil filled with germs and bacteria, why don’t you squeeze a stress ball? If you do want to chew on something… Try a healthy snack such as almonds, says a dentist at Cosmetic Dental Studios in New York City, Victoria Veytsman, DDS.
