Hi Sunny, I’ve had my share of mouth issues…and experiences from both sides of the dental chair. I was a certified dental assistant for 30+ year and as a cancer/bone marrow transplant patient, I have fun little things happen from time to time…insert eye roll! 🙄
For those moments, which are frequent, I have oral Dexamethasone rinse (prescription steroid) that I swish for 30 seconds and spit out. Along with that there is another prescription: Tacrolimus ointment that I apply to my tongue when needed. You may want to visit with a dermatologist instead of your PCP…just a thought.

Food allergies can really trigger quite a few autoimmune responses in our body. Do you have any other allergies or conditions of inflammation? Sometimes those parallel outbreaks.

As for the Pulling…that is a very old technique. Posted a couple links for you. I use a very high grade coconut oil but other people use Sesame oil or Olive oil. Coconut tastes good and feels soothing to me. Just don’t swallow it when you’re ‘pulling’. However, one drawback with Coconut oil is that it has natural salicylates which can also be an irritant if susceptible. I did smaller periods of 5 minutes instead of the full 20 minutes the first few days just to make sure I didn’t have a reaction. If nothing else it is a good anti-inflammatory/antibacterial product for the mouth.

If you try pulling, let me know what you think! 😄
