I found out that xylitol powder could reduce the amount of bad bacteria in your mouth! It kills plaque! How do I know this? I saw it on the telly (Korean health channel). It will get rid of tooth decay and periodontal disease. My source is https://www.healingteethnaturally.com
I use a xylitol powder on top of my pea size tooth paste (you're really not suppose to use more than a pea size of tooth paste).
Also, you're not suppose to rinse out your mouth with water after brushing your teeth.
You're only suppose to brush gently for 3 minutes, then spit out the tooth paste foam in your mouth.
I also do oil pulling. I use coconut oil and do it for at least 20 minutes to an hour.. depending on how much time I have. If I'm in a hurry.. I'll only do it for 20 minutes.
You can also swish wheatgrass powder (1/8 tsp) with a small shot glass of water for 5 minutes.
If you want to go all out, just buy some liquid chlorophyll (unflavored) and add one drop of it into your drinking water. Drink that everyday for health benefits!
