The dentist was amazing. Very good at explaining things. She was so good with my son. I was talking with the assistant and she already started giving my son a shot to numb his mouth. I was very worried my son wouldnt react well to the shot but not one peep out of him. I was very anxious about this appointment and this dentist made me very at ease
