Why have the bottom of my teeth turned grey after teeth whitening treatment?
Q. I had zoom 2 whitening done on my teeth 2 days ago but have now found that my two upper front teeth have gone white at the top and a greyish yellow at the bottom. I was told this would go but im very worried as my teeth look worse than they did before the treatment. What has caused this and will it go to white or are my teeth ruined. I had the in chair system done as i thought that would be the best. Im really upset as i had them done for my holiday next week and now im ashamed of my teeth. Please help,
A. It sounds as though you may have tetracycline staining. This is caused from childhood antibiotics that were commonly used in the 70’s and 80’s until it the negative effects on teeth were discovered. Whitening can work but may take a ot longer thena conventionla whitening systems. The results are not guaranteed, but prolonged whitening may have a better effect, but this may cause increased senstivity. Other ways in masking tetracycline staining is with porcelain veneers.
