Dental: my adult friend (all natural top and bottom teeth) saw general dentist yesterday who said that in office whitening would not help. she drinks coffee and some wine. teeth look brown. (i whiten at home custom trays). her to give up?

Tooth Whitening: Whitening can only do so much, especially if your friend's teeth are naturally dark. But why give up? She can try the procedure, either at home or in office. If it works, great... if it doesn't, so be it. Not harm will be done, and the cost is not prohibitive. Do not expect miracles or guarantees.

Don't give up: What was the reason the Dentist said whitening would not work? Trays work for some people, not all, but there are other alternatives. Before throwing in the towel it would be wise for your friend make an appointment with another Dentist for a second opinion.
