Hi Dr Butt,

I recently decided to give up smoking and tea/coffee as they were beginning to really show on my teeth. As a treat to myself i have decided that i want to have my teeth professionally whitened, but i am not sure what is the safest product/supplier with the best results..

This is where i was hoping your expertise could guide me.

I have done some research, but i am not sure were to look. I am approx a C2 on a professional tooth shade guide, an wish to get to a A1-B1.

Can you please advise, in your opinion, the safest and most affective product for a dentist to use?

Thanks
