Can any members  (with real experience of teeth whitening) share a suggestion of where to get this service e.g:

 

- name of clinic / approx location in CM

- rough details of pricing

- how many visits

- how successul was the overall treatment? e.g. Just 10% improvement ---- returned to pure 100% white.

 

Thanks
