Sinus Problems After A Root Canal? Here’s What You Should Know!

Root canals are a very common restorative procedure that can help save teeth after they’ve been damaged by tooth decay or an impact injury. While most root canals resolve without any major symptoms or post-operative issues, there are some exceptions.

Some patients may experience sinus issues after a root canal. What does this mean, and what should you do if you start to have sinus problems after your treatment? Here are a few things you should know:

Understanding Root Canals And Sinus Issues – How Are They Related?

Only root canals that involve your upper teeth can lead to sinus issues. The lining of the sinus is very thin, and your upper teeth are located extremely close your sinus lining. It is possible for a root canal treatment to damage this thin lining, especially if the dentist who performed your treatment was inexperienced or careless with their tools or the pressure applied.

During and after your root canal procedure, interactions between your upper teeth and your sinuses can cause a number of different problems.

Sinus Issues to Look Out For:

What are the most common sinus issues that patients experience after root canal therapy? Here are a few examples:

  • Sinus communication – “Sinus communication” is a medical term, referring to a very small hole in the sinus lining. This is the most common side effect, and it’s nothing to worry about. Symptoms may include sensations of air rushing over the socket, or fluid going from the mouth to nose while drinking.
    Because the hole is typically very small, it heals on its own in about 2-3 days, and you should no longer have any issues. If you continue to have problems, you should see an experienced family dentist like Dr. Williams or Dr. Ma right away.
  • Root canal failure – If your root canal fails and the source of the infection is not removed, pus will continue to build up in the tip of the tooth root. This may burst through the sinus lining and drain into the sinuses. The most common symptoms of this issue are clogged sinuses on a single side of the face, a constant runny nose, and a metallic or “musty” taste or smell.
  • Accidental puncturing of the sinus lining – This is usually only a problem if your dentist has been careless. If your sinus lining was accidentally punctured during the procedure, this can cause headaches and facial tenderness, along with pressure and sinus pain that does not go away after your root canal.
    A sinus puncture is different than sinus communication. “Sinus communication” refers to very small holes in the sinus which heal naturally, and are not uncommon during a root canal or a tooth extraction. In contrast, a sinus puncture is much larger, and usually requires sutures to heal properly. If this happens during treatment, you should find a new dentist.
