Do you know that teeth whitening is a multi-billion industry? But most of these whitening products have harsh chemicals which can slowly erode the enamel and leave your teeth feeling sensitive. The whitening chemicals also get absorbed through the skin of the mouth. Here are some safer ways to whiten your teeth instead.
1. Coconut oil pulling or swishing

Oil pulling is an Indian remedy used to improve the oral health and cleanse the mouth. The process is very simple and inexpensive; all you need to do is take one tablespoon of virgin coconut oil and simply swish it around in your mouth for 15-20 minutes. After moving the oil around your mouth spit it out and thoroughly rinse your mouth with water.
