I have a question that I couldn’t find an answer for: Do I need to rinse my teeth after drinking clear, unsweetened herbal tea?
The answer to this question will depend on the kind of tea that you are drinking. Many herbal teas are acidic and if you add some lemon you will definitely find this to be the case.
My suggestion would be to do some of your own pH testing. Also http://www.zellies.com/store.asp?pid=9842
Our pH testing kits are easy to use and give you the answer that you need if you drink this tea often.
Remember that xylitol is not the only tooth protective food you can use. Any dairy (cheese for example), nuts, fresh vegetables and even some fruits like strawberries leave the mouth alkaline. Have some fun and test to see the changes in order to understand mouth pH in relation to the foods you eat.
Good luck and keep in touch,
