I understand your problem katherinz, my teeth are also stained and yellowish I was very much worried, this is really very embarrassing. I feel shy in front of my friends, others people. I tried some home remedies to whiten my teeth, these helped me to some extent but after eating something my teeth again turn yellowish. So, I consult a dentist, he suggested me to make use of the Alta Teeth Whitening Product. I used it and you won’t believe from the very first use I started getting result, it works great and within one week my teeth becomes white, shiny. It is completely safe and I personally recommend you to try it once. Even you can consult a dentist also about it.
I hope after that your mother must get convinced. Good Luck!!!!
