Sun Weilian, Department of Stomatology, The Second Hospital of Zhejiang University School of Medicine: Hello! ”What you have is probably a “pregnancy tumor”, which is a kind of gum tumor. Generally, this is because of untreated or poorly controlled periodontitis before pregnancy, and after pregnancy, due to changes in hormone levels, some of the gums in the teeth will proliferate and form gingival tumors. Gingival tumors are treated with regular periodontal therapy, and depending on the case, a decision is made whether periodontal surgery is needed to remove the gingival tumor. Some smaller gingival tumors will shrink significantly or even disappear after thorough periodontal treatment. Gingival tumors are prone to recurrence. Larger gum tumors must be treated thoroughly periodontally first and then undergo periodontal surgery to remove the gum tumor after the periodontium has stabilized, do not rush, or it will be more likely to recur. For the sake of your own periodontal health and the health of your future baby, women of childbearing age should always remember to get their mouths checked before pregnancy, especially for oral diseases such as periodontitis, obstructed teeth and dental caries! Severe uncontrolled periodontitis can lead to miscarriage, premature birth, low birth weight babies, etc., and has an impact on the whole body health of the pregnant woman. Please pay attention to oral health and treat oral diseases as early as possible to prevent problems before they occur!
