My husband took our 4 year old daughter to the dentist a few days ago (it was her first visit) My husband pointed out a that her front tooth has a little spot on it to the dentist. The dentist said it is a cavity and minor cavity and made an appointment to fill it. My husband said that this cavity did not show up in the xray. I am concerned that maybe our daughter doesnt need a filling done. Her tooth is not dark, the color is slightly different from the rest. I dont know what I should do.
