Q. Hi, I used to be an nhs dental nurse some years ago and I take care of my teeth and gums. Every dental surgeon I assisted gave their patients’ teeth a full and comprehensive scale and polish as standard. I still receive nhs dental treatment but, since the new scale of charges was introduced a few years ago, neither of the dentists I’ve seen have done much on the scaling and polishing side, with the result that my 5 lower front teeth, for the first time in my life, have became stained. I visited my dentist last week, pointed out to him the stain trapped between my teeth, and told him that my son is getting married soon, so he scraped off the stain on the front surfaces, but not the stain trapped between the very tops of the teeth, and I still have the brown edges. I floss my teeth each day, and I neither smoke nor drink alcohol, strong tea or coffee and I don’t eat much spicy food. I’ve tried a polishing paste, but still the stain remains in between my teeth (my teeth do not overlap). I need something like an abrasive matrix strip to get between the teeth and get the stain off. Do you know of such a product and where I could obtain it? Sorry for the long explanation!
