Tooth infections can be massive tricksters. I had two infected teeth which did not hurt, so I put off having them pulled for a long time, I can't remember how long. Then, when they went to pull them, the nerves would not accept anesthesia. This was a nightmare for both oral surgeons and me. A man in another state finally got them out, but said I'd need general anesthesia if I tried that again. Now, I watch the situation more carefully. Teeth cost me at least 20% of my annual income. More than that if you count going out of state as I had to do twice.
I don't remember getting sleepy from this, however, Just very anxious.

Some might say, why don't you get dentures. Can't because I have bony growths in the palates which are painless and harmless but make x=rays a contortionist situation, and preclude wearing dentures. So implants it is, and I'm grateful I do very well with those, having strong jaw bones. But they cost a fortune. I am working on #9 and 10 now, the implants are in (look marvelous, they say) and the ceramic tops will go on in a couple of weeks. This procedure is MUCH easier than having badly infected teeth pulled.
