As we know that the PH ranges from 0 - 14 , ere neutral PH ranges from 7.0 ,so below the the 7 is called acidic and above the 7 PH is called basic / alkaline .
Here our body maintained the PH ranges from 7.35 to 7.45 PH .
according to General of Emergency Medical Services GEMS.
You should know that Toothpaste directly effect in our enamel.
Acidity or basicity depends to our teeth demand ,If you want to whitening you teeth then take paste having 3.76 acidic property and 9.6 basic property. according NATIONAL HEALTH SERVICE.
So an American Association said that for enamel protection the salty paste is favorable . So the PH ranges which best for enamel protection is 6.6 which is very week acidic.
as my opinion 6.8 PH ranges is best because its not contains acidic property and almost contains basic property so excess in every thing is not good you should use which thing containing both quantity.
