Whilst the research is still early on and fairly limited, and only at trail stage, it certainly looks like applying the Q10 directly to your teeth is an effective way of combating oral problems, gingivitis, bleeding gums etc.
The trial is indicating that the Q 10 is effective on its own, or when coupled with a program of scaling plaque from the teeth.
Teeth problems can beset many of us, and so any positive results are great news. I've certainly told my son about the research and hope he makes use of the advice!
