tooth stain remover pen

[artdecomirror]

can anyone recommend a tooth whitening pen for stains caused by black tea?
i've got airflow cleaning booked but it's not for a while and want to just minimise a couple of the worst marks in the interim.

I bought the Philips zoom pen (came from the US) and I really find that it has improved the stains on my front teeth. Well worth the money imo 😊

This sounds strange but the best and cheapest thing I have bought is a wisdom stain eraser which is basically a tooth handle with a fine pumice. Has removed calculus.
i brush with bicarbonate of soda made into a paste with hydrogen peroxide.
Eat an orange daily for the citric acid( rinse afterwards) Use any whitening toothpaste.
Cheaper than any bleaching trays etc too
