Gum pain in children may be caused by gingivitis, apical periodontitis, periodontitis and other diseases, which can be treated with medication, surgery and other treatment measures. 1. Gingivitis: For gum pain caused by gingivitis, parents can use anti-inflammatory rinses such as Compound Chlorhexidine Gargle and Compound Borax Gargle under the guidance of the doctor, as well as non-steroidal anti-inflammatory drugs such as Ibuprofen Suspension Liquid and Acetaminophen Granules orally. If the child’s gum shape can not return to normal, you can take gingivoplasty and other surgical treatment. 2. Periapical periodontitis: Periapical periodontitis can also lead to gum pain in children, and it requires a complete root canal treatment to cure. 3. Periodontitis: For gum pain caused by periodontitis, parents can use antibacterial agents such as chlorhexidine acetate solution and borax gargle as prescribed by the doctor. Children with periodontitis can also undergo surgical treatment, such as bone grafting, flap surgery, dental implants and other surgical procedures. When children have symptoms of gum pain, parents should bring their children to the doctor in a timely manner, follow the doctor’s instructions for treatment, and use medication as prescribed by the doctor.
