Toothache or Sinus Problems? How to Tell the Difference

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.

I've been coming to this practice for years now since moving to the Raleigh area. The office is always clean and organized and the staff have always been friendly and communicative. Also, the TV's mounted to the ceiling are a nice touch! I've been seeing Dr. Laster for several years before our insurance changed causing me to change to Dr. Rensch. Both are so easy to talk to and always made me feel at ease.

From beginning to end 5/5! I thought I was experiencing a dental 911. I submitted an inquiry at 11:30pm and by 8am the next morning, Deidra (front office staff) was already leaving me a message. She was so sweet and patient at 8am lol. After our initial conversation, I informed all follow up dentists “I found my dentist office” but thank you so much! Today I was welcomed with the same energy from Diedre to Britany then finally Dr.Wrench. The music playing throughout the office was fantastic; ie music selection and volume. The TV’s on the ceiling and wall made my procedure so painless and enjoyable! I watched an entire Christmas movie lol! Dr. Wrench (apologies for spelling) made my teeth absolutely perfect! I left telling my friends and family I have a million dollar smile! 😊 I can tell he wanted them perfect and he did! Thank you all so much for being amazing! Sincerely, Your next patient.

Dr. Laster and Dr. Rensch go above and beyond for their patients. I have seen both for various treatments and I always feel comfortable and heard. They take time to listen and to talk with you. They explain your options and work with you to develop the best plan for your care. They are always upbeat and positive and you can tell they truly love what they do. The front desk staff is exceptional as well. Deidre is so caring and very sweet. She’s efficient, understanding and conscientious of your time. I highly recommend.

Connections Dentistry was great! The staff is so friendly and truly cares about their patients. My appointment was quick, and honestly the best dental experience I’ve had. They are great about offering helpful solutions without making you feel like you are being reprimanded… which was the reason I was putting off the dentist. 100% recommend!
