What should I do about crooked teeth?

When teeth are severely misaligned, a medical evaluation should be sought to determine the cause and severity. Depending on the degree of misalignment, orthodontic treatments such as fixed braces or invisible aligners may be required to gradually realign the teeth using external force. If the misalignment significantly affects normal occlusion, tooth extraction or dental implants may be necessary in some cases to restore proper dental function. It is also important to avoid不良 habits like nail-biting or pen-chewing, which could worsen the condition.
