I would suggest a different dentist. My husband has always hated dentists, pain and shots. We recently began seeing a woman dentist who is amazingly gentle and kind. She knows my husband has dementia and takes extra care to laugh with him and keep his attention so that he is willing to be alone with her for appointments and he does not even ask where I am after arrival. She has two small children and is able to handle him easily. This dentist discovered his tongue cancer and removed two of his teeth that were broken then replaced them with a clip in prosthetic device so he could chew better.
