Children’s tooth decay pain can be relieved by medication, surgery, other treatments and general measures. 1. Medication: Children need to use fluoride under doctor’s instruction, such as sodium fluoride glycerin paste, etc. For children with severe pain, they need to take ibuprofen, acetaminophen and other painkillers as prescribed by the doctor. 2. Surgical treatment: For children with defective dental tissues, surgical treatments such as amalgam filling, inlay restoration and composite resin direct bonding restoration should be considered. 3. Other treatments: In the early stage of the disease, remineralization therapy and fissure sealing can be considered for treatment. 4. General measures: Children need to strengthen the management of oral hygiene, reduce sugar intake, and pay attention to relieving tension, anxiety and fear. Usually, children with tooth decay need to strengthen their daily life management, go to the hospital in time, and get treatment as soon as possible to avoid delaying their condition.
