PH should be 7 or better. Color of strips should not matter as long as you use the color code chart that comes with the strips

Mercola has a useful article on the topic as well.
How Coconut Oil Might Combat Tooth Decay

This topic is several months old not but you should watch this video. It is a CBC marketplace program that visited 20 dentists and got 20 different diagnosis all costing thousands of dollars. The patient did not need any work done but the dentists all wanted to do expensive work. Dentists have mortgages to pay and sturent loans to repay and they need the money so they recommend work that is not needed.
Watch the video it is very enlightening....
