For protrusion, torsion and invagination of single tooth, porcelain crown correction can generally be considered. Porcelain crowns are priced according to the material, generally about 800 cobalt-chromium porcelain crowns and 2000-4000 all-ceramic crowns. But when it comes to real correction, it's like 14 people standing in a narrow space, and one person is crooked, so everyone must move to make room for this person, and only then can there be a neat team. Therefore, even if a tooth is to be corrected, it is because of different regions, materials, ages and expenses. The basic error correction fee is 8000 yuan.
