Someone told me that brushing with a mixture of lemon juice, salt, and baking soda would be good for whitening teeth... would this work? or is it bad for my teeth?
--------------------
Lemon juice may make ur teeth look good and clean temporarily, but then your teeth becomes even yellower. And lemon juice is a citrus - VERY high acid. It erodes the enamel and makes ur teeth sensitive and takes off what you put on the teeth like calcium. Baking soda once again can whiten the teeth but is still harmful to the enamel. For both of these (and salt) I recommend NOT over-doing it. Salt is by far the best, but for lemon juice and baking soda, keep it to a minimum. And make sure you brush with normal toothpaste after using baking soda
