In brief: Depends

35% carbamide peroxide is very effective on most discolored teeth.
You will usually see an improvement after three applications. However, some teeth are very resistant to bleaching particularly teeth that are grey. Since the results vary from patient to patient there is no way to accurately answer your question.
