Question
My child is 8 years old and just had an upper front tooth replaced. It seemed to be a cavity before. After the tooth was replaced, I noticed a gum bump. What could this be, and will it interfere with the new tooth?
Answer
Based on your description, this condition may be due to the recurrence of decay in the remaining milk tooth, which causes another abscess to appear on the gum. Since the permanent tooth is erupting, this situation requires timely dental treatment at a hospital. In some cases, root canal treatment may be necessary, including drilling, root canal irrigation, nerve calming, and finally root canal treatment, to ensure complete healing.
