Andreas Kalcker's protocol J - Dosage: 10 ml. of CDS in a 200 ml. glass of water. Initially, wash your mouth and gargle 3-4 times a day for 3 minutes. Later on, you can do it just once a day. Another way is using a toothbrush to brush the teeth and massage the gums. For deep inflammations, add 1 ml. of DMSO (see below) to the mix. It’s important to rinse the mouth at the end.
It goes on to add more info. You might consider buying some of his books if you are into CDS (as I am).
