Tea is gentle on almost everything except, it turns out, the colour of your teeth. The tannins that give it character are also excellent at staining. Here's how to lift existing tea stains and stop new ones taking hold.
Why tea stains teeth
Tea is rich in tannins, plant compounds that cling to enamel and leave colour behind. Black tea is the worst offender, but even lighter teas add up over time. The staining is mostly on the surface, which is good news - surface stains are the most responsive to both better habits and whitening.
Stopping new stains
Rinse with water after a cup to clear lingering tannins.
Don't brush immediately after acidic drinks - wait a little so you're not brushing softened enamel.
Add a splash of milk - some find it binds tannins and reduces staining.
Stay consistent with brushing and cleaning between teeth.
Lifting stains you already have
For staining that's already set in, whitening is the reliable route. Surface tea stains respond well to both purple optical brightening and gentle peroxide. Our Purple Whitening Strips neutralise yellow-brown tones for an immediate lift, and a daily Purple Mouthwash helps keep that brightness topped up between deeper sessions. Skip the abrasive DIY scrubs - they cost you enamel for a short-term look.
Frequently asked questions

Does green tea stain less?
Generally lighter than black tea, but it can still leave a dull cast over time.
Will I have to give up tea?
No - rinsing, good habits and occasional whitening let you keep the cup and the smile.
