I can manage to get the toothbrush into my husband's mouth and clean his front teeth and gums but he refuses to open his teeth so that I can get the tooth brush into clean the back of his teeth. I stand in front of him with my mouth open trying to prompt him to do the same, all to no avail. I have tried opening his teeth with my finger, sometimes it works. I have tried offering him a spoon in the hope that he might open his mouth fully for food. Not much success with that. He has beautiful teeth and I dread to think that he may lose them because of poor dental care. He always took such good care of them. Does anyone have any suggestion please?
