The usual consequences of leaving some gingivomas untreated include increased size, infection, and loose or displaced teeth. However, in the case of gestational gingivomas, there are no adverse consequences to leaving them untreated, and they may subside on their own after delivery. Gingivoma is an inflammatory growth in the periodontal membrane and connective tissue of the gums, which can be divided into fibrous gingivoma, pregnancy gingivoma, and giant cell gingivoma. If fibrous gingivomas and giant cell gingivomas are not treated in a timely manner, the size of the growths will increase, which will affect the aesthetics to a certain extent. Moreover, the increased size makes it easier to be bitten, which can lead to ulcers and increase the chances of complications and infections. In addition, as the growths continue to increase in size, they are prone to cause further damage to the alveolar bone, so the teeth may become loose or shifted. However, pregnancy-related gingivomas are usually left untreated with no adverse effects, and may subside on their own after the pregnancy is over. In conclusion, patients with gingivomas need to go to the hospital in a timely manner, strengthen their daily life management, and actively treat them if necessary.
