My daughter is fifteen years old, nowadays nothing is going well for her. From early childhood, she is very much concerned about cleanliness. She used to wash the plates which my wife has already washed. Also, she is having a habit of washing her hand often. She is obsessed with dirt and contamination. I hadn’t given much attention to it. For about a week she is suffering from gum recession. I think vigorous brushing is the cause for it. She is having the habit of over brushing too. I am going to book an appointment for gum disease treatment from a clinic in Mississauga ( http://www.parkerhilldental.com/our-services/gum-treatment/ ). But I have no idea about how to make changes in her habits. Can anyone help me with some ideas?
