Tea and Your Teeth
Tea, whether black, green, or herbal, has both benefits and drawbacks when it comes to oral health:
-
Benefits: Green and black tea contain polyphenols that can reduce bacteria and promote oral health.
-
Concerns: Tea is slightly acidic and contains natural pigments (tannins) that may stain your teeth over time. Black tea, in particular, is known for causing discolouration.
What Happens If You’re Drinking Water After Tea?
Drinking water after tea is not harmful—in fact, it can be beneficial for your teeth:
- Washes Away Acids: Tea can lower the pH in your mouth, making it slightly acidic. A sip of water helps neutralise acids and protect enamel.
- Prevents Stains: Water rinses away tannins and pigments before they settle on your teeth.
- Reduces Dry Mouth: Tea contains caffeine, which can reduce saliva flow. Drinking water helps keep your mouth hydrated.
So, drinking water after tea is actually a good oral care habit.

Common Myths About Tea and Teeth
-
Myth: Drinking water after tea causes tooth sensitivity.
Fact: Sensitivity is more often linked to enamel wear, gum issues, or very hot tea, not to water. -
Myth: Green tea doesn’t stain teeth at all.
Fact: While lighter than black tea, green tea can also cause staining over time.
Tips To keep Teeth Safe While Drinking Water after Tea
- Drink water afterward – particularly if it’s black tea or green tea.
- Use a straw to minimise contact with your teeth.
- Don’t add sugar – sweet tea is more likely to cause decay.
- Brush after 30 minutes – brushing right after acidic beverages can damage softened enamel.
- Drink herbal teas conscientiously – they are often more acidic than you would guess.
