< p> Hello, whether you can do orthodontics depends not on your age, but on the specific situation of your teeth, such as severe gingival atrophy, crowded teeth and uneven occlusion caused by bone problems, so it is not suitable for orthodontics. Because gingival atrophy will affect the roots of teeth, and orthodontics is to rebuild alveolar bone. Without the support of gums, hasty orthodontics will lead to loose teeth or damage to teeth. However, the bone problem needs to be comprehensively improved through surgery combined with orthodontics, otherwise, it will not solve the problem if the bill is corrected. < /p> < p> Therefore, in other words, as long as the teeth are in a healthy state and do not belong to bone problems, no matter how old they are, they can be improved by correction, but the orthodontic time is different. Because the principle of orthodontics is to make the teeth move in the specified direction by applying pressure, and when the teeth move to the specified position and fully recover, they will be the same as natural teeth, because the alveolar bone is also being rebuilt during the slight movement of the teeth, and after the reconstruction is completed, it will not have any impact on the oral cavity. < /p> < p> Therefore, as long as it is not a special reason, you can do orthodontics at the age of 25. As long as you follow the doctor's advice, check regularly and do a good job in dental care, you can generally see the orthodontic effect in about 1~2 years. The above is the relevant answer about orthodontics, hoping to help you. < /p>
