Patient: I have tetracycline teeth, darker in color, and I don’t know if tooth bleaching and cold laser can be effective. I have heard that porcelain veneers are relatively less abrasive, so I don’t know if I can adapt to them. I want to choose a suitable for myself and the least damage to the teeth. In addition, the material of porcelain teeth is more suitable for all-porcelain or metal porcelain, what are the advantages and disadvantages of each? If the plan can be determined on the day of the visit, can it be done on the same day? The upper and lower teeth are done together? Dental Hospital Restorative Dentistry: The choice of treatment plan for tetracycline teeth depends on whether your teeth are straight and the patient’s own requirements to choose. My treatment principle is a conservative treatment that preserves the dental tissue. The first choice is bleaching, but not if the final result is demanding; porcelain veneers are a very good choice, but the requirements of the doctor is very high, and to have good preoperative communication with the patient; for the treatment of tetracycline teeth I have now basically do not recommend patients to do porcelain teeth, because its preparation is large, and the color is not transparent, patients are often dissatisfied with the very white porcelain teeth after 1 or 2 years, unnatural. I have never seen a patient on the first day to start the preparation of the patient’s teeth. Both the doctor and the patient should be careful, and both should have a lot of preparation to do.
