In a survival situation, I might try something my oral surgeon did for a tooth I just had removed because of a benign infection that I and my family dentist buddy missed ----who I went to in the Spring and didn't detect the decay, there was a sensitivity we thought was receding gums for at least 6 months.
4 weeks ago I associated it with an infection in my cheek and some weird neurological sensations in my cheek.
I started Augmentin and Flagyl right away, got an appointment later in the week, family dentist filled one tooth #15 and prepped #14 for the surgeon to do a root canal, bone graft to build it up for a titanium stud, wrote a script for the same AB's, and got me in fast with the surgeon.
A few days later surgeon extracted the root, showed me a concoction of Augmentin and Flagyl and cadaver bone powder he mixed and packed into where the root was.
Stitched it up, sent me home with a script for the same AB's ---and oxycodone I really didn't need.
Playing with the missing tooth spot and a loose stitch with my tongue now. The stitches have come loose a tiny bit two times and my SO clipped them. SO looked at this one this morning and said it was a loop and didn't want to clip it.
Have a second follow apt the end of this week. Will get it clipped.
Cost LOL! ~$400 for the family dentist, $2200 for the work done so far to do the root canal and bone transplant
Have to wait 5 months for the bone to be reinforced and heal.
Then--- ~$2000 for the titanium stud and THAT has to heal for 5 months.
Then back to my family dentist for a crown, about $1200.
Assuming no complications.
In a survival situation, I'd study -or get someone to- the cavity, clean it mechanically [Dremel or eBay tools] if the pain could be withstood, put in a tiny amt of clindamycin or Augmentin and fill it with the fluorinated glass ionomer.
LOL!!!!
Then have it fixed ASAP.
