Over the counter systems do not work as well

go to a profesional, to get a deep cleaning, polishing and also to get it done and supervised by an specialist, all those dental companies, that sell products, do not tell the patient, that if teeth are not clean form the bottom, the materials would not work, remember that plaque is always present no matter how hard you brush, or apply materials, go to see professional.there are many systems

Hi There,

Not all enamel is the same.  The uptake on the whitening product can vary.  That being said, I cannot tell why you cannot obtain the brightness you once had.  I would go professional - Zoom Whitening!  That is our favorite brand of in-office whitening treatments.  Call around to offices and see who has done the most.  Then set up an appointment for a consult first.  Maybe there is a reason that dentist can detect clinically.  Best to correct that first so it does not happen again. And always get the whitening trays that go with Zoom.  That will really lock in your color after the in-office procedure.  Best of luck to YOU!

Hi!  If you are not getting results with over the counter whitening, you probably need professional whitening.  Try zoom whitening or Kor whitening.  It should get you better results.
