Apart from surface staining can drinking a lot of tea harm teeth?

Question

Answer 1

Drinking herbal tea may damage teeth, dentists have warned.

Researchers at the University of Bristol Dental School have found these teas erode the enamel or protective layer on teeth.

Some are even more harmful than orange juice, which is very acidic and is known to harm teeth.

However, one of the UK's leading manufacturers of herbal tea, Twinings, rejected the claims.

I think perhaps that traditional tea has no harmful properties that will harm you outside of surface stains as you mentioned.
