I think teeth bleaching is one of the greatest advances in cosmetic dentistry .In the past people with discolored teeth had only one option, crowns!
So many perfectly healthy teeth were ground down needlessly just to change their shade or color. With teeth bleaching this is accomplished very conservatively, safely and for a fraction of the cost.
For the most part there are two ways to bleach your teeth, either in-office or take home. In-office bleaching usually relies on high concentrations of bleach to give you an effect right away. These high concentrations however also can cause a lot of tooth and gum sensitivity and whenever you want to bleach again you need to go back to the office to have it done which makes it the more expensive method. The take home method involves making custom bleach trays, which then you wear in the comfort of your home. This method allows you to choose the strength of the bleach you want to use depending on your tolerance and achieves or exceeds the results of the in-office method. I also like the fact that when the time comes to bleach again you can acquire the bleach from your dentist for a nominal price and not have to pay for a whole bleaching procedure from scratch, more bang for your buck if you ask me.
However before you bleach consider a few factors .Do you have any crowns or fillings on your front teeth? If you do, you have to take into account that bleaching works only on natural tooth structure, so as your teeth get whiter your restorations remain the same color which might not give you the most cosmetic result .So before you bleach, have a chat with your dentist and see where you stand. Your old crowns and fillings can be changed to match your new white teeth but you need to plan for that prior to bleaching. That way you are making the choices for the overall appearance of your front teeth and will not be disappointed with the results or the cost.
