Cristian, I have recently developed a brand new presentation on the use of low level frequencies in dentistry I haven't posted here yet. I'd be happy to share it! It covers the use of FSM (Frequency Specific Microcurrent) to relieve pain & inflammation in post-surgery dental patients. It also includes information on how specific FSM can be when addressing oral tissue, and how subtle frequencies have proven effective in treating other oral hygiene issues such as infection. If you'd like it, I can email it to you. My email is [email protected]. Have a great day!
