green tea, rinsing, bite guards, pockets, and gray teeth

Hi Ellie,

Thank you so much for your great work and information. I have been doing your regimen for about 3 weeks now. I am so glad I have more guidance in this arena and know now about PH, etc.
Some questions for you:
-I am a big green tea drinker in the morning. How long should I wait after brushing/rinsing before drinking my tea?
- you say a quick rinse with Listerine, at 30 secs max. Doesnt it take 30 secs minimum to kill the bacteria? confused about this part...
- I wear a bite guard and have been told it is autoimmune? Not sure what this means? I would love to stop using it at some point but my teeth have been badly damaged from grinding apparantly.
- I have a lot of pockets so I rinse for 2 mins with Closys, and follow the rest religiously, will they go away with this method?
- I have a gray tint to my teeth and I have not seen anything in your literature about gray vs yellow. Will they whiten too as they get healthier?

Thanks again,

Clark
