question: Hello doctor,My 7-year-old child had a small filling about a month ago in his top premolar (baby tooth). Two weeks later he said it hurts a little when biting and with temperature. I have taken him to two different pediatric dentists who did X-rays and did not see any cracks in the filling or infection. Occlusion was also checked, and the tooth was polished down a bit. He still complains of minor pain in the tooth when biting hot and cold.
