My three year old has a newly forming cavity in a cuspid tooth. We have consulted with a dentist in our neigborhood and he has advised us not to treat the tooth with a filling at this time. He suggests just watch the tooth and keep it clean. He says that the tooth should not cause her any pain. That is exactly what I am concerned about. I don't won't her to wait up one morning with a terrible toothache. What do you recommend? I am also concrened that she may have another cavity that maybe I haven't seen. What should I do and is it possible this tooth could cause her pain eventually?
