Make your own natural teeth whitener! Cheap and healthier way to whiten your teeth with stuff you probably already have sitting around!
2 Tbsp Baking Soda
2 drops lemon oil (lemon juice will work too)
1 drop water (enough to make it into paste)
Get your teeth as dry as possible and gently brush the mixture onto your teeth. Let it sit for a minute and then repeat until desired whiteness is achieved!
