If it is not improved, the color of teeth will continue to deepen and become dark gray or brown.

2. The degree of tooth coloring is different, the anterior teeth are obviously colored, and the permanent teeth are not colored. After coloring, the teeth will become transparent, the enamel will become thinner, and the tetracycline color in the tooth tissue will not be easily covered. Over time, the teeth are getting yellower and yellower, which seriously affects the personal image.
