Tooth deformity should be treated as soon as possible, and the best time to correct it is deciduous teeth, permanent teeth and mixed teeth. The time for early treatment and correction is also short. Don't miss the best correction opportunity. If you miss the best correction time, you can wait until 18 years old for adult orthodontics. Stomatological Hospital I trust Xinya Stomatology, which is the best choice because of its advanced equipment and technology and high doctor qualification.
