Enlarged tonsils usually affect the operation when straightening teeth. 1. When tonsil hypertrophy is more obvious, when correcting teeth, such as grinding teeth or pulling out wisdom teeth, the operation during orthodontic treatment is likely to be affected because the site is adjacent to and closer to the tonsils. 2. In addition, tonsil hypertrophy is often caused by inflammation and infection, if orthodontic treatment at this time may require tooth extraction or other treatment of the teeth, which may cause the release of bleeding in the mouth, triggering infection, leading to serious tonsil hypertrophy, and may even cause tonsillitis, peritonsillitis and so on. Tonsillar hypertrophy is generally recommended not to correct the teeth for the time being, need to actively cooperate with the doctor to take treatment, when the tonsils return to normal, and then orthodontic.
