I'm a 29-year-old male who got both wisdom teeth on the right side extracted
three weeks ago. The bottom tooth was slightly impacted and only half of the
tooth had broken through my gums. I have read before that it is supposed to
take about a week for the "holes" to close up, but since this has not
happened I wanted to ask whether my situation is normal. My dental health is
otherwise good. I've never had any cavities, but I'm a bit of clencher.

The top socket healed within two weeks to where it was more of an
indentation than a hole, but not much seems to have happened since then. The
bottom socket is still a big  hole where food gets trapped etc (I rinse it
out with a syringe). My dentist told me that it would heal from the bottom
up, but it's hard to how it is progressing, because it's hard to see the
bottom of the hole.

Do I just need to be more patient? Is it possible the whole will not fill up
with tissue?

Thank you!
Marcus
