2. Yellow or stained teeth
You can breathe easy on this one: Stained or yellow teeth are almost never a sign of serious dental concerns, says Dr. Worth. “These stains develop from drinking coffee, tea, wine, or other dark or staining liquids.” Whitening toothpaste, strips, or a trip to your dentist can solve the problem. “It’s also a good idea to rinse or brush your teeth after consuming these liquids to prevent staining in the first place,” she adds. (Here’s what to look for in whitening toothpaste.)
If the stains are brown or stripe, on the other hand, this could be the result of tetracycline antibiotics you were administered as a child, or from other medications, Dr. Cram adds. “It doesn’t mean the teeth are damaged, but your dentist can take cosmetic steps to remove those stains.”
