Q. My teeth are slightly yellow and this is really affecting my confidence, brushing them isnt making any differnce, also on one side at the back of my teeth i have a yellow build up of plaque which looks horrible i think its tartar, my dentist does not have a hygenist at the momentand so cant offer me treatment for this as it is a privite treatment. and every dentist i call says they cant clean and whiten my teeth as i am not registered with them, is there anywhere i can go to get my teeth cleaned and whitened without moving dentist? also would loke to do this as soon as possible. apart from the yellow i have two metal fillings at the top back of my teeth and two white fillings at the bottom.
