Toothache or Sinus Problems? How to Tell the Difference

May 23, 2023

Woman sneezing into a tissueContrary to what you might have heard, an occasional toothache isn’t normal. It is often a symptom of an untreated dental issue, like a cavity or an infection. With no treatment, you can eventually lose your tooth. However, dental pain is also linked to sinus problems. How do you know if your toothache requires a trip to your emergency dentist or if your sinuses are the culprit? Here’s what you need to know to make the best decision for your smile.

Can Sinus Problems Cause Toothaches?

Your maxillary sinuses are located on either side of your nose by your upper back teeth. Your sinuses are responsible for producing mucus to keep your airways clean and moist. However, allergies, illnesses, and infections can cause a buildup of mucus that can lead to pressure in the sinuses. 

With your teeth in close proximity, irritated sinus can cause dental pain. If your pain isn’t localized to a single tooth and it affects your upper molars, it’s likely your sinuses are responsible for your toothache.

Home Remedies to Treat Sinus Congestion

Treating your sinus issues will stop your dental pain. You can try many home remedies to reduce the pressure, like:

  • Stay Hydrated: Drink plenty of water to stay hydrated. Healthcare professionals recommend drinking at least eight 8-oz glasses of water daily.
  • Steam: Steam can help loosen mucus to treat nasal congestion. Opening the airways will reduce congestion and alleviate your dental discomfort.
  • Sinus Flush: A sinus irrigator can clean mucus from your nose to reduce inflammation.
  • Decongestants: use a decongestant to reduce sinus irritation. However, don’t use the medication for more than 3 days or your sinuses and nose can become too dry.

Home Remedies for Toothaches

While waiting for your sinus pressure to subside, you can manage any dental discomfort using a few tips:

  • OTC Pain Relievers: Take an over-the-counter pain reliever
  • Cold Compress: Apply a cold compress to the affected tooth.
  • Saltwater Rinse: Rinse your mouth with salt water to reduce bacteria, inflammation, and pain. Gargling with it can treat a sore throat caused by post-nasal drip.
  • Soft Foods: Eat soft foods that require minimal chewing until your pain subsides.

If your toothache doesn’t improve after resolving sinus congestion, it’s time to visit your dentist. If your pain affects a single tooth, do not wait to schedule an appointment. Your dentist will get you into the office quickly to provide the personalized solution you need to stop your pain and safeguard your smile.
