Ayurvedic oral hygiene includes cleaning your tongue in the morning after brushing your teeth. Most people often develop a coating on their tongue during the night. This mixture of toxins and bacteria is often a cause of bad breath, periodontal disease or tooth decay. Under no circumstances should the tongue coating get back into the body. The easiest way to clean your tongue is with a special tongue cleaner. This only takes a few seconds, but has an excellent effect on your overall well-being.
