For teeth whitening - is Biolase better or blue spectrum LED light, or another method?

Independent research into all bleaching techniques show that neither lasers or lights do anything to increase the effectiveness of bleaching products. The very best results come from high concentration in-office bleaching followed by at home bleaching trays.The bleaching products used are what matters, not the  lights or lasers. One of the most effective bleaching products on the market today is KOR bleach; no need to add any lights or lasers that do nothing but add heat to the teeth which increases sensitivity.Good luck!

Please not its the concentration of the material being applied that gets the results!  The light source doesn't make much of a difference in the outcome of the procedure. However one aspect that matters greatly is how often you maintain at home!  Think of teeth whitening like getting a sun tan! The more you maintain, the deeper the glow!All the best,

It has long been proven that the light does little to speed up the whitening. Tray whitening such as KOR, Day White or Opalescense is still the most. Effective. In office whitening does speed up the process but doesn't always get teeth their whitest. Most types of whitening are very safe, but remember this isn't a one time process.
