So sorry to hear about this, but it sounds like it is necessary for him. I would first make sure you are using a quality probiotic daily -life9 can be opened and swished in the mouth before swallowing to help with dental health. Mightypro is a child friendly alternative. There is also an entire course in the courses section to check out with tons of helpful info on how to use cell salts and work on gut health and the like. I would do a detox after his procedure (also check out the courses on that) and work on dental health and remineralization if needed!
