A great find!
I bought this tooth brush for my son who is twenty seven. He has special needs and has autism. He has remained filling free but his teeth are very badly stained because he eats dry coffee and tea. It is impossible for his dentist to clean his teeth because he is so fearful so I was delighted to have found this toothbrush which made an immediate improvement of about 85%. It is quite powerful and noisy but I introduced it gradually desensitising him to it. I'm delighted both for him and me. Thank you.
