Top Causes of Teeth Staining

One of the biggest complaints heard in cosmetic dentistry offices is stained teeth. Yellow teeth make your smile dull and can actually make you look older. Fortunately, with teeth whitening treatments, your dentist can restore a whiter look to your teeth so you’ll be happy to flash your smile again. After teeth whitening treatment, you can maintain your results for longer by avoiding these common causes of teeth stains.

Coffee and Tea

Coffee and tea are notorious for causing teeth stains. Their dark colors cling to the surfaces of your teeth, and over time, the stains become deeper and deeper. If you are someone who likes to sip coffee or tea throughout the day rather than simply drinking a cup and moving on, then your staining is likely to be even worse, since you bathe your teeth the discoloring liquids for an extended period of time. After teeth whitening, you can reduce the impact of coffee and tea on your newly whitened teeth by drinking them with a straw, so the liquid doesn’t have to swish across your teeth. Drinking a cup quickly and rinsing your mouth with water can also help.


Berries may be a healthy choice, but yellow teeth could be the cost for this snack pick. The dark colors in berries will stain your teeth the same way they stain your clothes. The impact is the same whether you eat the whole fruits, drink them in juices, or eat them in jams. You don’t have to cross berries off the menu completely. Simply eat them without lingering over them, drink plenty of water, and consider a glass of milk afterwards to reinforce your enamel and reduce staining.


Certain medications, particularly some antibiotics and antihistamines, can cause deep teeth stains that are resistant to whitening treatments. Talk to your doctor about this potential side effect. If this kind of staining does occur, veneers can help.
