About 2 weeks ago (maybe 3, but I really think 2) I noticed a brown spot on one of ds's molars (bottom, second from the back).
I am in ds's mouth regularly to clean it - more than just brushing (I do this while he sleeps) and had not seen it until it caught my eye when he laughed one day. It's possible I just had not been looking for it in the right spot - it was kind of on the back top part of the tooth, but when I saw it I was certain it was a cavity.
I began paying extra attention to that spot, which even felt a bit pitted when I would clean it with a tool. I began to follow ds's meals with a xylitol crunchy probiotic and took extra care to clean that spot every night with his normal tooth care, continued to brush with xylitol toothpaste, and also applied a tiny (very, very tiny) bead of Tom's of Maine toothpaste with fluoride to that spot each night.
I was hoping to arrest or at least slow the decay so that we would not need to treat this tooth right away as ds has MAJOR dentist anxiety. (He actually has anxiety issues in general and sensory defensiveness, so combined the dentist is a HUGE trigger... I suspect he would require anesthesia for pretty much any kind of treatment).
Anyway, over the last week the brown spot was becoming harder to find. The last two nights I took a really good look with a mirror and can't see it at all. Where it was brown is now white, like the rest of his tooth, but sort of more translucent in a way that makes it seem like the enamel there is much thinner.
This definitely seems like a good change, but was so much faster than anything I expected.
My question is, what was that, what happened, and how did it happen so quickly?
