Warning - long post regarding re-growing teeth coming up. If you're not interesting in that subject you might want to skip this post.
Hi Miles - That cap of yours might get in the way. I've felt like my teeth need to be able to "breath" for the lack of a better word to heal. It's like they need for me to be able to care for and feed them properly. If an infection starts because I ate something wrong I can use colloidal silver so they don't have to fight that and I feel like my teeth absorb things they need directly in the mouth.
My teeth when I was regrowing them just had holes from cavities. When I was eating badly after that they broke and were horrifically painful. They no longer hurt me at all now as long as I don't eat anything bad - but I haven't been eating ideally so no regrowth has happened. I hope that can still happen with them more deteriorated than when I did it the last time. It's still amazing to me though how they react so directly to how I eat. My teeth keep my diet at least ok because if I get too far off track they give me a big kick in the teeth to put me straight.
I would say Miles that there is no downside to eating what is ideal and right for you if anything happens with that tooth or not, because the teeth are a barometer for you health in general - especially your stomach and digestion - so whatever you do for them will benefit the rest of you.
I personally wouldn't take that cap off to see if you can regrow the tooth underneath unless you feel it is hurting you in some way. It takes tremendous commitment, self-restraint and delicate fine-tuning of the diet to get to the point where re-growth occurs and if you don't achieve it, the break down makes the upside not always worth the potential of the negatives with the downside of removing fillings or caps. Root canals though - can be very dangerous to one's health. If there is a root canal closed off under that cap - that's a whole different animal. You would have decide what to do after doing lots of research on the subject first. Thank goodness I never got a root canal done.
Glycerin in toothpastes is really bad I have heard. I found one in the store that feels really great for my mouth. It's called Bee Rescue Propolis toothpaste (gluten free). Ingredients: Water, baking soda, xanthan gum, propolis extract, grapefruit oil, clove oil and tea tree oil. It's the only one I could find in a store that didn't have glycerin.
I'm also growing horsetail plant to chew on later. It's supposed to do good things too.
I didn't use either of these when I had success - so don't be too worried if you can't get them. I just think that any extra knowledge from people that have studied natural tooth care and healing can't hurt.
Another trick is acupressure. Stomach 5 and 6 are powerful points to work if you have pain in your mouth. I bet working the stomach meridian would be helpful with healing teeth as well - but I haven't been trying that. When I get serious about regrowing my teeth again, I will use acupressure as it was one of the only things that could help with the tremendous pain when I ate badly and the regrowth broke down. I'm pretty sure now that the stomach meridian being clear is vital to healthy teeth and that is why diet makes or breaks teeth - so I betcha it is also something that could only help the healing process.
