The common cause of orthodontics is uneven or protruding teeth. Most orthodontists rely on tooth extraction to make room for the displacement and arrangement of the whole row of teeth. If the teeth are slightly irregular, the teeth are large enough or the gap between the teeth is large, there is no need to extract teeth, but it is also possible to use molars instead of extracting teeth. I don't think you need to worry too much about not pulling out your teeth. The key is to get the best results. The doctor said it was conservative treatment not to pull out the tooth first. If tooth extraction is needed, it will not affect the health of teeth. Don't be afraid of pain Don't be afraid. I know that teeth play a very important role in a person's overall image.
