Hi @MonkeyOwl and welcome,
Personally, your stacks didn’t sound like “too much” to me (I sometimes use twice your amount lol) even though “less is (often) more”, as they say.
Have you tried Bacteria Destroyer, in addition to teeth/gum fields? As you know, bacteria can be among the main causes of cavities. Maybe you also lack some minerals and/or other nutrients. Or you may also be ingesting some foods prone to create cavities, etc.
Other members would probably have additional suggestions.
Edit:
I was going to suggest Advanced Healing but it can be a bad idea if you’re currently lacking minerals/nutrients, since it’s a quite strong and “demanding” field. That is, your problem may not be only a bucco-dental one, but the symptom of another health condition (happening synchronistically but independently from the fields you’ve been using so far).
Anyway, in order to relieve more localized pains/problems, I suggest you the Healing card on Patreon (you already subscribed, right?). Be sure to use the Attunement one beforehand.
Here’s also the link from the forum:
Keep us updated :)
