Slightly off topic but, my dentist said that in older people, sometimes, the enamel wears off the tooth and the yellow that can then be seen is the dentine inside the tooth. It doesn't seem fair that years of regular brushing can actually cause yellowing!
I think that must be why some people go for veneers or bonding. I'd love to have all my teeth bonded or veneered but it can be very pricey!
Should the NHS charge for such things?
Churchill to be axed from British banknotes in the name of diversity.
