Hi Robert
I am Cm from India. I am not sure this work for you, but we are using this herbal method for us. Try yourself with confidence. Mix Sea Salt and Pepper to with clove oil to use to wash/brush your teeth everyday. Clove oil is not important. Rinse your mouth at least 6 to 10 times after brushing. Take enough time for brushing teeth.
Do not eat sweets after 6 PM.
Use only normal cool water to wash your head.
You may have to use some tablets for release pain for the first time.
Best of luck
Have wonderful days.
