Thoughts? could my teeth change their color by drinking black tea?

Staining: Your teeth may stain by drinking dark liquids.

Tea can stain: Black tea can stain teeth and everyone differs in how much this happens. So try to limit the amount of tea you drink. Drink more water, this is better than too much caffeine.

Black tea: Coffee and tea can cause external staining of teeth, but do not change the actual color of teeth. Brushing properly after drinking these liquids limits the staining. It's also dependent upon the frequency of use. A dentist can always professionally clean your teeth and remove the staining.
