I have never had cavitation surgery , but I am planning too in a year or so. I am sure that if you develop an infection, your dentist can prescribe Antibiotics , your insurance may not pay for it, but Antibiotics are typically inexpensive. So, ask this dentist before hand if they would prescribe Antibiotics in case of an infection, even if you're going long distance and are far away when you get an infection they should be able to wire it to your pharmacy.
Also, look into Colloidal Silver . I plan on using this for my recovery to prevent an infection if my dentist agrees.
I hope this helps, and wishing you all the best,
Ashley
