Many people have dark teeth due to Tetracycline stain. Many have been told that their staining is due to Tetracycline and it is, in fact, not due to Tetracycline. No matter what the cause, there is hope with deep bleaching. Deep bleaching involves a very specific technique with a combination of home use trays that are designed and fabricated to seal the bleaching material on the teeth and an office treatment that uses unique bleaching chemicals that whiten deep into the teeth. Treatment involves three visits and a commitment to nightly home treatment. The results are incredible.
