Can grey teeth from probable tetracycline be whitened with KOR? (Photo)

Hi There! Thank you for taking the time to share photos, that is helpful. I am so glad you have taken some steps to help prevent further wear on your teeth. From what I can see in the photos, it does look like Kor could help, but it will take some time and commitment to get the improvement. To fully evaluate, I would need to see the teeth in person!

only option to correct tetracycline staining is veneers or crown, whitening will not help. as u r concern about veneers pricing u can go for dental tourism to reduce costing. you will save upto 70% on total costing. dental tourism is very famous for cosmetic dental procedures and dental implants.

Typically, tetracycline stained teeth cannot be bleached.  These teeth are stained intrinsically, and bleach removes outer staining on the teeth.  A good alternative for you is porcelain veneers.  Although I have not done an exam on you, and I am judging off some blurry photos, you look like you are a heavy grinder, and that you have lost some vertical dimension of occlusion (meaning your bite has collapsed from the grinding).  You will need to do your research and choose a dentist that is very knowledgeable and skilled with teeth like yours.  If you do have a collapsed bite, and you were to put on veneers on the front teeth, they would break because of your bite.  You would need to have your occlusion (bite) restored first, and then have the veneers placed.  Like I said, make sure you do your research on your dentist when you go down this path!

the KOR system would be the next logical step for you if you cannot afford to rebuild your teeth--do realize that un worn front central incisor teeth are about 11mm long--yours look to be about 50% of that length. So even with whiter teeth they are very very worn and short.

Having said that, you should limit your expectations.  Grey teeth in general do not whiten as significantly as yellow/orange teeth.  If anything will help, it is the KöR system, and ONLY the "max" version.Directions must be followed in their entirety.  There can be no short cuts or alterations to the program, or else it simply will not be much different than anything else you have tried.
