What's the difference between bleach and laser on teeth whitening?

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

What's the difference between bleach and laser on teeth whitening?
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.
Reply:i best bleach is the chemical and the laser is using bright light to whiten?
Reply:Laser whitening or in-office whitening will do the trick far better and quicker. In-office whitening is usually done in one appt of one hours time. Whereas whitening trays you have made in office and wear home at night, you must wear for one hour each night for about 10 days. See what I'm saying! Both results will be pretty much the same. In-office runs about $600 in canada, and home bleaching runs roughly $300. I know you said price didnt matter just thought I would throw that in! Good luck, and happy whitening!!!
Reply:the home bleaching will take longer to do, but its better if your teeth can suffer from sensitivity as the bleach is not as strong , you will get the same results as laser but it will just take a little longer to achieve and its actually cheaper the home bleaching,


laser whitening can be really sensitive , my teeth went hyper senstive after for a day or so and i know my colleagues have had the same problem,


my opinion is the bleach is better then the laser, and costs less and reduces ure chance of any discomfort , easy winner in my opinion and u can stop when ure happy with the result where as the laser will bleach to a shade u have no control over


good luck
