(1) It hurts during orthodontics. Generally, it hurts for about 2-3 days after you go to see a doctor for a follow-up visit, that is, after the doctor applies force to your appliance. Generally tolerable, it is a feeling of pain. Very few people are particularly sensitive to pain and take painkillers, but they stop taking them once or twice.
(2) The pain in the correction process is not a problem at all, and it is within the tolerable range. After correction, the most important thing to pay attention to is maintenance. You should insist on wearing a dentist's tailor-made maintenance device to maintain the correction effect to the end and give up all previous efforts.
(3) Why does it hurt? Periodontal membrane is composed of nerves, blood vessels and cells, and there is also a dental band connecting teeth and alveolar space. When the tissue is deformed, the blood circulation is blocked, forming a state of hypoxia. At this time, the surrounding cells will release some neurotransmitters to stimulate the nerves and inform the brain. When a tooth is subjected to a slight and persistent external force such as orthodontics, the tooth itself will not be painful, but this force will squeeze and pull the periodontal ligament between the tooth and alveolar bone.
