1) it might not work
3) pain and swelling, bruising
4) depending on where it is being done, you can get a sinus perforation, or damage to the mandibular nerve.
Make sure you know of the alternative of retreating the tooth. 99% of the root canals I see are treated with retreatment first. Apicos are last ditch efforts to save a tooth. Most failures of older root canals are a reinfection. An apico does not deal with that. In general, the apico is only done when the dentist thinks there is a secondary canal at the root tip and they want to cut it out.
Being a diabetic, you are at risk of not healing up as well. The less controlled diabetic you are, the higher the risk involved.
I hope I opened your eyes to further discuss your risks and options with your endodntist before proceeding.
occur with extractions, implants, periodontal surgery, etc. This is the main reason why I recommend re-treatment of the root canal rather than surgery as a first choice. Most endodontists are retreating root canals that did not respond to the original treatment rather than surgery. Re-treatment offers a higher success rate when performed by an endodontist
compared to surgery on an infected root. If the tooth is properly cleaned out, then surgery success rates rise. Of course, re-treatment is usually more time consuming and will damage the crown, necessitating a new post and crown. Surgery is faster, but if it doesn't work, then what?
