7. Lemon juice and baking soda for a shiny smile
Give this simple and efficient home treatment a try before investing in teeth whitening bleach products. Lemon juice mixed with baking soda in equal portions works wonders for teeth. This turns into a paste that you apply to your teeth for a few minutes.
But be cautious! Because of its acidity, lemon can aggravate an existing lesion or mouth ulcer. Also, please don't go too far and substitute it for your toothpaste! You're still going to need that, buddy. Regardless of how bright your grin is, no one wants to smell that lemon breath.
