<s>[INST] Hello my 5 year old daughter had like a temp filling done on Wednesday the uv light ones, she didnt have any drilling done or anything but that night she woke with tooth ache bought some medicine and was fine but now her cheek is quite swollen, I didnt know if this was due to as they was pressing the filling on she was screaming and moved a lot and disrupted the nerves and wil calm down in few days? [/INST] Hi Sir/Mam, I can understand your children problem. When ever a tooth decay develops sensitivity, it means the decay has entered second layer of the tooth. When there is pain or swelling in relation to decay tooth it means it has entered third layer of tooth which has nerves and blood vessels. Once the decay enters the third layer, root canal treatment(in adults) or lumpectomy is the permanent solution. But since your child had bad experience with the previous appointment. You can wait for one more month taking medications. If again pain and swelling develops you can proceed with root canal treatment. Hope your query is answered. For further queries please don't hesitate to contact me. </s>
