Although one of America’s favorite morning and afternoon beverages may be coffee and tea, they have compounds called tannins, which can cause unsightly stains and discoloring of your teeth. Therefore to avoid staining your teeth try and limited the amount of coffee and tea drinking throughout the day.
If you are going to be drinking coffee and tea do so with a straw to limited contact with your teeth. Avoid slowly drinking these types of drinks, it can be fun to hang out at the local coffee house and babying the one cup of coffee during your hour or more stay but it is not so fun for your teeth.
