My teeth need whitening. Badly.
Scale & polish help to remove the obvious stains, as does airflow treatment, but does nothing for the yellowing!
So people, please tell me, are there any otc whitening treatments that actually work?
I've been reading up on whitening strips and was thinking about giving them a go.
I'd rather avoid spending hundreds on professional whitening if I can help it, but I will go down that route if it's the only option.
