I've also heard that, because there is no blood circulation in the teeth themselves, infectious organisms can hide inside teeth...am bummed but not surprised Lyme can do this too.
I had a lot of trouble with my gums bleeding despite daily brushing/flossing...and then discovered chewing real chicle-based chewing gum (not the synthetic petroleum-derived gum base used in most common chewing gum brands) has caused my gums to stop bleeding for the first time in my entire life.
I've also had episodes of a few consecutive teeth, or even just one tooth, start hurting and the dentist not able to find anything wrong with the tooth/teeth. More recently I've had episodes of migratory gum pain...my solution is to rub a drop of clove essential oil on the painful location. It burns a little when first applied, but after that the pain goes away. I've also had gum pain migrate to an untreated location in my gums (after Lyme diagnosis), confirming another strange location for the "migratory pain" of Lyme...
I suspect that tooth whiteners probably kill off at least some of the "friendly" bugs in our mouths in addition to cleaning stained teeth, which may explain the increased tooth sensitivity. I doubt if this critter-killing is limited to the area where the whitener is applied...but this is only my opinion.
Tooth health also has a genetic component, according to more than one dentist I've seen. I'm certain genetics play some role in my tooth issues (in addition to the effect of Lyme on teeth).
