I was wondering if anyone knew of home remedies to whiten the teeth...I am poor and can not affort to go to the dentist to whiten my teeth so I want to try something that won'r cost me a arm and a leg.
Be careful with the hydrogen peroxide, it's a known carcinogen as is the alcohol you find in your Listerine mouthwash.
Don't be overly aggressive with your brushing when using the baking soda, it can scratch the enamel of your teeth (just like comet on a bathtub). Dipping a wet toothbrush in baking soda once or twice a week may help whiten your teeth.
You should determine if the stains are intrinsic (internal which means the above solutions won't help) or extrinisic (caused by your diet and habits).
