Hello Dr Hughes. I hope you can help us. I would like to know if you treat children for orthodontics who have been on biphosphonate treatment for osteoporosis?  My daughter is 14 years old and has been on and off treatment for 8 years.  I have had her on waiting lists for up to two years only to then be told that now they won’t treat her, even though her consultant has said the risks are minimal.  Is this something you or any of your colleagues can advise us on? She is desperate to be treated because she also has overcrowding that can be painful at times. Thank you.
