It’s like when people have cancerous tumours removed. On the one hand, in many cases, they need to be removed to preserve life; on the other hand, the patient will have to make changes in their life otherwise, they would return. Lipomas would be the same in that if the root causes aren’t dealt with, it’s likely that they would come back in the same place or elsewhere.
In Jeffery’s patient’s case, I suspect the teeth would have been the source of taxing the system and leading to the loss of latency and resources. Like when you stop eating inflammatory foods, the inflammation in the gut goes away.
