Catherine -This may seem odd, but i have had exactly the same experience recently. My dentist had given me a "you're nuts" look when I told him. I am having my two back bottom right molars crowned at the same time. After experiencing pain during the grind down of both after the first round of novacaine, he hit me with another series of shots.
Sometime during those last few sticks I felt a tremendous flush of heat and a sudden tinge of pain radiate down the center and right side of my tongue. I knew something was different, but I didn't recognize what until the numbness in my face wore off, while a numb-like feeling remained in my tongue.
Here's what we have in common:
1) I have a numbness radiating in the right-side of my tongue.
2) Everything I eat has a tremendous salty taste, almost directly derived on the right-side. I even seem to taste it from my lips?
I thought I was crazy, or suffering from some weird malady. Thanks for your post.
It's been 2 weeks since the first sticks, and I have had work performed a week later for further prep of the crowns. while I still have some residual numbness, it is diminishing. However, the saltiness seems to remain. If I had to make a guess, soem neural remapping has occured from damage to the nerve.
I have some experience in this area fortunately, as my previous training was in biochemistry and human physiology in college. I feel strongly that given some time, our brains will re-learn to map the incoming signals that have been cross-mapped to reflect the salt-sensation.
