Wisdom teeth in the upper teeth that are rotten and loose are usually recommended to be extracted. The teeth that bear the main biting force are the first and second molars, while wisdom teeth do not bear the main biting force. The eruption of wisdom teeth is usually non-orthodontic, so they do not have a normal occlusal relationship, so in the case of wisdom teeth rotting loose, we can choose to remove them. Meanwhile, it should be noted that even if the orthodontically erupted upper wisdom teeth are rotting and loose, we also suggest that we choose to remove them. This is because the wisdom teeth are more backward, more difficult to treat, and the treatment time is longer, the treatment process will cause more pain to the patient, so the treatment is not very meaningful. It is recommended that patients have their wisdom teeth removed in a regular hospital stomatology department.
