Jim Wood tells a story about teeth that makes him smile. Wood — a dentist and a state assemblyman from Sonoma County — remembers the time a patient of his who was an elementary school teacher told him about a student suffering from serious dental problems. The little girl’s family was poor and they lived in a rural area. They couldn’t find a dentist to treat her. The family lived too far for them to travel to Wood’s office in Cloverdale. But Wood was able to find a dentist closer to their home to treat the girl.
