Your wife's excellent dental exam is so encouraging for her and all of us!! I too am only a 5 minute swisher, and within the first week of swishing I did notice increased teeth whitening and by the 2nd week a little less gum redness. I had this thing about not getting all the oil and hence germs out of my mouth after my swishing as I could always feel a residue, so I did a little research and found another component to add to my oil swishing regimen that eliminated my oily residue sensation and has really enhanced my gum healing. I have a dental appt. next month which will be the true test, but after adding the 2nd component my gums are now pink not red, and pretty tight with no further bleeding even with flossing. For those interested in my 2nd dental regimen component go to the web site of holistic dentist Dr.Behm at saveyourteeth.com. I oil swish in the am and do Dr.Behm's Secret in the pm.
