One of the most common questions we get from patients having teeth extractions is how do I prevent dry socket. While most don’t know exactly what it is, they most definitely know one thing- that it is very painful. And they are certainly correct.
Dry socket, also known as alveolar osteitis, is a painful complication that can occur after a tooth extraction, specifically when the blood clot at the extraction site is dislodged or fails to form properly. This exposes the underlying bone and nerves, leading to increased pain and delayed healing.
When asked about dry socket, I first let them know that it is certainly a potential complication following teeth extraction. Then, I re-assure them that is extremely rare- In fact not even a single patient with dry socket during my 27 years of practice. No, it is not just luck! Rather, it is an understanding of the risk factors and how to minimize them.
Smoking, poor oral hygiene, aggressive spitting, and use of straws following teeth extraction, have been cited as chief contributing factors to dry socket. These are primarily patient-influenced factors. But there is also dentist-influenced factors that in my experience, is even more significant. Such factors include prolonged surgery, excessive reflection of gum tissue, traumatic surgical techniques, overheating the bone due to inadequate irrigation during drilling, and excessive bone removal. These factors can disturb the cascade of blood clot formation and wound stability, which in turn can impact the healing biology resulting in poor or prolonged healing, infections, and certainly dry socket.
Hence, to prevent dry socket, we must minimize both patient- and dentist-related factors. Let me Share with you our protocol for minimizing the risk factors for dry socket:
Minimize patient-influenced factors:
- Provide patients with very detailed and easy to understand post-operative instructions. First, we provide patients a written post-operative instructions and then review it verbally line by line to make sure they understand it. Then we send a 10-minute video showing them exactly what to do and not to do during the post-operative period.
- We highlight known risk factors such as smoking, poor hygiene practices, aggressive spitting, and use of straws that can compromise the blood clot.
- During our call to patients on evening of surgery, we encourage them to review the written and video instructions and emphasize good hygiene practices, avoid use of straws in the first 24 hours, and discuss benefits of smoking cessation for those who smoke.
Minimize dentist- influenced factors:
- Use minimally-invasive and atraumatic surgical techniques during extraction
- Avoid raising gum flap to optimize blood supply to the surrounding tissues
- Avoid excessive bone removal when extracting impacted wisdom teeth or broken roots
- Treat the extraction socket, surrounding bone and gum tissue gently and with kindness.
- Use plenty of irrigation during surgical extractions to avoid thermal injury to bone and surrounding gum tissue
- Protect the blood clot using collagen materials plugged into the socket and sutures.
Thorough patient education with clear instructions that are well understood and practiced along with critical surgical techniques by experienced oral surgeons, are the key ways to prevent dry socket following teeth extractions.
