A tooth growing outward from the upper gums is mainly due to insufficient eruption position of the teeth, which may be the maxillary cuspids, maxillary wisdom teeth, etc.
1. Maxillary cuspids: Because the maxillary cuspids erupt later than the premolar and lateral incisor on both sides, there is often a lack of eruption position and lipward eruption, resulting in a tooth growing outward from the upper gums.
2. Maxillary wisdom teeth: Because of the mismatch between the amount of teeth and the amount of bone due to the evolution of human beings, the maxillary wisdom teeth often appear to have insufficient eruption position and erupt in the labial direction, which results in a tooth growing outward from the upper gums.
There may be other reasons why the upper gums grow a tooth outward, it is recommended to go to the hospital in a timely manner, improve the examination to clarify the cause of the disease, under the guidance of the doctor to give targeted treatment or treatment.
