Yellow Enamel. I Have Done the Tray Thing That Doctor Sold?

There are different products and different procedures for teeth whitening. If the take home trays did not work for you, your dentist should give you alternatives. Some teeth are harder than others to bring up to a nice white shade. We use Kor Whitening,  which we have had  great results from on all of our patients.  It involves in office whitening which you follow up with take home trays and sometimes, another in office whitening to achieve the desired results.  Talk to you dentist and see what other products and procedures he uses that will bring them up to the shade you desire! 

In-office whitening can be more effective than the trays you have already tried. You may be able to get better results, however with whitening there is no way of know how white your teeth are capable of getting.
