There are many reasons why you may get stains or discoloration on your teeth. Some of the most common causes of stains on the teeth include:
Food and beverages: Things such as coffee, tea, red wine, fruit juice, berries, beets, soda, and dark-colored vinegar can all stain the teeth.
Smoking: Tobacco naturally yellows the teeth leading to discoloration.
Aging: Over time, the outer enamel layer gets thinner from brushing and more of the yellow dentin shows.
Medications: Certain high blood pressure medications, antihistamines, and even antipsychotics can lead to tooth darkening.
Thanks to advancements in teeth whitening technology, teeth whitening can improve a smile. After just one treatment, many patients see their teeth become several shades whiter.
