Brush with whitening toothpaste.. And then use a damp toothbrush dip into bakeing soda and brush somemore.. Try not to rest lips on teeth.. Keep it on there for as long as possable then rinse.. It's ok to do it everyday.. Peroxide is alright but taste gross and is hard to keep on the brush and if swallowed too much can make you sick!
brush your teeth with baking soda. not the stuff you get from the supermarket though. you are looking for either organic baking soda or 100% sodium bicarbonate. i have used it to brush my teeth for 2 years now due to allergies. i can confirm that it works a lot better than toothpaste for whitening teeth. and it is cheap. just wet your toothbrush and put a pile of the stuff on the brush. then brush
Just drink plenty of milk. You only need to brush your teeth once a month if you drink two cups of milk a day. Trust me, I'm a dentist, and I have to tell people that they have to brush twice a day. But drinking two cups of milk is more efficient. - James K. Wallace, Orthopologist-University of Dallas
