I'm just wondering which does the best job. Cost doesn't matter, I need to know which is faster also. thanks

Recents studies show that: 1. "In-surgery bleaching that require only one visit are to be viewed with scepticism. Patients who had only one session had a higher relapse that those that had 2-3 sessions. Approximately half of the patients with 2-3 in-surgery sessions requested additional home bleaching to improve the result." 2. "It is possible that dehydration of the teeth could be a contributor to the whitening seen in one-visit procedures." In other words, one-visit treatment looks better initially because it dries out the teeth temporarily, but that the teeth rehydrate and change back much of the change. So, go for the home bleaching - it will take longer, but give better results.
