Last time I took my daughter (nearly 4) to the dentist she wouldn't open her mouth at all whereas the previous two times she opened it very briefly for the dentist to look in. We are going again on Mon - any ideas of what I can try?!
ds went through a phase of this and Our dentist was brilliant, she gave ds a ride in the chair, let him play with the mirror, chatted to him, made him laugh etc. She never pushed him to look in his mouth and eventually he was fine.
