I’m Having Sinus Problems After a Root Canal. What Does It Mean?

If you’ve recently had a root canal, but now you’re having sinus problems like post-nasal drip, sinus pressure and congestion and other similar symptoms, you may be wondering if this is related to your recent treatment. Learn everything you need to know about sinus problems after a root canal from Sarasota Bay Dental now. 

You May Have a Sinus Communication Causing Sinusitis-Like Symptoms

This is the most common cause of minor sinus problems after root canal therapy. A sinus communication is a small hole in your sinus lining, which may be opened by your dentist while they are performing a root canal.

This happens because the roots of your upper teeth are extremely close to your sinus lining, which is relatively delicate. When cleaning your tooth during a root canal, your dentist will use a special tool to remove decayed material from the roots of your teeth. It’s possible for them to accidentally poke through the sinus lining and create a very small hole, or sinus communication. 

Usually, this results in symptoms like:

• Feeling air go across the socket of your tooth when you breathe
• A runny nose or post-nasal drip
• Congestion, sinus pressure, and pain

‍
These symptoms are relatively mild. If your sinus communication is small, it will heal on its own, and you will not have to seek further treatment. However, if your pain and discomfort persists or gets worse, you may have a larger hole in your sinus lining, and you may need treatment to close this opening.

Your Root Canal May Not Have Been Successful

An infected tooth can actually cause sinusitis because the roots of your upper teeth are very close to your sinuses. If your root canal is not successful and your tooth remains infected, it may cause sinusitis as it gets worse. This is known as “sinusitis of dental origin.” The bacteria may spread from the roots of your upper teeth into your sinuses, causing a sinus infection. 

If your tooth continues to hurt and feel uncomfortable after your root canal for more than a day or two and you also notice sinusitis-like symptoms, it’s possible that the treatment was not entirely successful. Root canal re-treatment may be required to remove the remaining infected material from your tooth.

Know When to Get Help for Sinus Problems After a Root Canal!
