A natural [Ayurvedic] oral care protocol: The first thing in the morning, scrape your tongue with a tongue scraper or the back of a spoon to remove any mucus especially on the back of the tongue. The tongue should be pink and clean.

After each meal follow these three steps:

• Brush with a simple tooth powder such turmeric powder with cinnamon powder and a little neem powder. You can just use turmeric but many other substances depending on the condition of your teeth and gums can be used.   Salt can also be used or added in small amounts. Sea salt is also a very effective way to clean your teeth when you don't have any other choices. Charcoal, on the other hand, works very well in times of infection even for a tooth ache.  If you are not ready to make your own tooth powder, I recommend these brands: Auromere and Theraneem.  (Of course, don't use any commercial brands especially with fluoride and don't us baking soda as it is too harsh).
• After brushing, rinse the mouth thoroughly and gargle with a disinfecting formula such as filtered mineral water with 1 tsp. of Himalayan salt, a pinch of baking soda (aluminum free), about 10 drops of tea tree oil and 3 drops of clove oil (optional).
• Next, after brushing and rinsing, do oil pulling by taking about 2-3 tsp. of sesame oil (not coconut oil) in your mouth and "pull and push" the oil between the teeth for about 5 minutes before spitting out the oil.  You can massage your gums too if necessary.
• Then, in between meals clean your teeth and massage your gums with a wooden tooth stick (Miswak stick). Carefully scrape away any buildup of bacteria, food or plaque around the gum line both on the inside and outside of the teeth.
