Deep bleaching - No success?

[Marina]

What if tetracycline teeth get lighter after 5 weeks of deep bleaching (KOR Whitening), but get dark again 3 days after you stop bleaching? Did it happen to anyone?

Thank you for your post.

Tetracycyline stained teeth are probably the most difficult teeth to whiten. Many times the patients who suffer from tetracycline staining give up on whitening and have veneers placed on their teeth instead.
