Nearly all the whitening methods are similar in concept, but some are much more effective because of the way the whitening material is delivered to the teeth. Another contributing factor is the concentration of the material, which is why less potent over-the-counter whitening systems usually don't give patients the results they are hoping for.
On the other hand, in-office whitening is the most efficient means of whitening. There are a number of different types used, but the process is very similar for these methods; you can have your teeth whitened in one session and achieve significant results. Most discolored teeth can be lightened to a much whiter shade. Your dentist can give you more detailed information and help you decide which method is more suitable for you and your teeth.
