Last time i did, she removed my infected rc another molar who gave me nerve pain, and opened up the extraction site from last time and took something out she said i think was an infection about half an inch in diameter.
She probed the extraction site and there was indeed a little canal going up in the bone to my sinus, she put ozone in, cleaned everything nicely, i have high hopes and happy i went.
Now hoping i heal up good.
Btw did see an objective documentary on dental implants and turns out 40% of patients experienced troubles along the way, also has a lot to do with the dentist and the patients health i quess.
