Dentist Questions sinus infection

Can sinus infections cause tooth pain?

I have a sinus infection, but I noticed that my teeth are actually hurting with it. I'm only taking decongestants for it until I can go to the doctor. But in the meantime, can sinus infections really cause tooth pain?

Yes! Typically sinus infections put pressure on the upper back molars and can mimic a tooth ache.
Yes-- I have had many patients come to me on an emergency basis for perceived tooth pain ("upper molars") only to learn that they have a sinusitis.
Yes, pressure from a sinus infection can cause tooth pain or sensitivity. Usually this can be treated with antibiotics.
A sinus infection does not cause tooth pain per say. However, having a sinus infection can make the upper teeth feel as though you are experiencing tooth pain due to proximity of the sinus to the upper teeth root ends. For a sinus infection see your primary care doctor to rule out a sinus infection before seeking out a dentist.
Yes when you have sinus infection the pressure from the sinus can make your teeth feel in pain because is certain places the roots of your teeth are very close to the sinus which can cause referred pain.
Yes, sinus problems can cause pain in your upper teeth. The roots of your upper teeth are separated from some of your sinuses by only a thin membrane.
A few years ago my wife showed up at my office with a severe pain in her upper teeth. Based on her dental history, I was sure that the pain could not be caused by damage to her teeth. After taking a panoramic x-ray to rule out other possible toothache causes, I noticed a remarkable sinus infection. Consultation with an ear-nose-throat (ENT) specialist, confirmed my initial finding of an acute sinus infection.

Toothache can cause feelings that could be associated with sinus infections and vice-versa, because they share a nerve. Patients with headaches, nose congestion and even fever, may not realize that these symptoms could be related their simultaneous toothache. Going to a dental office is the best thing to do in these circumstances. A dentist can make an accurate diagnosis based on a clinical exam and an X-Ray.
Yes, indeed, a sinus infection can cause tooth pain especially in the upper jaw in your posterior teeth. The nerve that innervates those teeth passes in the sinus, so if it is infected, you might experience dental pain. However, the pain will go away once the infection clears. If it does not, consult a dentist.
Yes, for sure. The roots of your teeth are right near the sinus.
A maxillary sinus infection (maxillary sinusitis) can cause a tooth or several back teeth to hurt and feel as if they are extruding from their sockets. Have to get an xray to exclude any pathology related to the tooth.
Sinus infections can cause tooth pain. Sometimes the roots of the teeth are right next to the sinuses and pressure can build up in the sinus and cause discomfort in the teeth. I would follow up with an ENT and your dentist to rule out other causes of the tooth pain.
Great question! It can cause tooth pain because the nerves for the upper back teeth can sometime extend into the sinus. One way you can tell if it is sinus or an actual tooth ache due to a deep cavity is lay down and see if the pain goes away in your tooth. If it does, then it is more than likely sinus however, to make sure I would see a dentist.
Sinus infections can cause your teeth to hurt. In order to properly diagnose your situation, I recommend that you see a dentist.
Yes. A sinus infection can cause toothache. Best to see your internist. You may have to take antibiotics.
Yes, sinus infections can cause tooth pain. Other common occurrences that can cause tooth pain are allergies and changes in barometric pressure.
Yes, pressure in the sinus can compress the nerves that provide sensation to our teeth causing pain in the maxillary teeth.

A sinus infection can definitely cause tooth pain. Pressure develops in the sinus which rests on top of the tips of the roots of posterior teeth. Because nerve endings enter your teeth at the tips of the roots this area is compressed when sinus is inflamed due to infection or allergies and this can lead to tooth pain. You should also be aware that a tooth infection can travel to the sinus leading to an infection in the sinus.
Your sinus cavities are above your teeth. Sometimes the roots of your teeth are in your sinus cavities. When you have a sinus infection, your sinus tissue is swollen and filled with material, mucus, and pus. Your body is fighting the infection. Besides having your nose blocked, this added material is putting pressure on the area above your teeth. Sometimes when patients come in with their upper teeth hurting, nose drainage you maybe placed on an antibiotic. Once the infection clears and your teeth are not hurting, the pain was caused by the infection process placing pressure on your teeth.
Absolutely! Especially on the top rear teeth. It will feel like a toothache due to the fact the sinus pressure is pushing on the nerve exiting the apex (or tip) of the tooth root!

Have a great day!

Most definitely. The Maxillary sinus is in your cheek and the nerves to the upper teeth travel along the floor of that sinus. If there is a disturbance in the sinus, such as an infection the nerves to the teeth in that area can get aggravated and simulate a toothache. This can also happen from seasonal allergies or if you have a cold. Keeping the sinus clear with antihistamines usually helps greatly in relieving this issue.
Yes, they can. But the same applies the other way; teeth problems can also cause sinus symptoms; I would highly advise you make a dental appointment for a consultation.


Dr. Andy Gaertner.
Yes, often when patients have a sinus infection the increased pressure can put pressure on the top teeth and create tooth pain. If this is the case the tooth pain should be relieved when the sinus infection is resolved.
This is a difficult question to answer without any X-rays or a clinical exam. However, the posterior teeth (the molars) roots often are in the vicinity of sinuses and if teeth are compromised, i.e., defective root canal or issues with teeth. Therefore, patients often can have either problems and have pain. It should be correctly diagnosed and treated.
Yes, sinus infections can absolutely cause tooth pain. The best course of action is to see your dentist asap to determine if this is dental or sinus related pain. If you are able to take Ibuprofen, the studies indicate this is the best medications to alleviate teeth pain until you are able to see your dentist or physician (I would recommend an ENT).
Good luck!
Sinus infections, in fact, can cause back teeth to hurt. Also, a tooth going bad and getting infected can cause sinus infections. You may want to have your teeth checked out by the dentist first.
Hope this helps!

Yes, they can... especially the upper back molars as the roots of those teeth are usually very intimate with the floor of the sinus. I would see your MD and then give it time for the sinus infection to clear. If you still have tooth pain after that, see your friendly dentist as you could have a tooth infection as well.
Yes, any kind of sinus inflammation/infection can make the teeth in that area ache. A good test I give my patients to discern between sinus and tooth is to have them jump up and down a few times...if you feel that in your mouth - it's more than likely a sinus issue.
