Why Sinus Infection Tooth Pain Occurs

Sinusitis, more commonly referred to as a sinus infection, occurs when the nasal passage cavities become swollen and inflamed, according to the Mayo Clinic. The sinuses are unable to drain which allows a mucus build-up. It's usually caused by the common cold but can also result from allergies. Once the sinuses are blocked, the moist environment created by an excess of mucus creates a fertile ground for infections. Another symptom that could affect your oral health is bad breath from postnasal drip, according to the American College of Allergy, Asthma & Immunology.

In many instances, the cause of tooth pain is evident (take a long gulp of some cold water on that tooth for confirmation). But a sinus infection can be the culprit due to the main mantra of real estate: location, location, location. The roots of the upper molars are in close proximity to the sinus cavities. So when the sinuses become infected and swollen, the resulting pain is often mistakenly believed to have originated in the teeth. If you think you have a sinus infection, make an appointment to see your doctor. Over-the-counter medications might offer some pain relief but a physician will best be able to determine your course of treatment.

In addition to seeing your doctor – who might prescribe an antibiotic for pain relief – you can try some home remedies from the U.S. National Library of Medicine as well. Use a warm compress on your face several times each day. Increase your fluid intake as a means of thinning the mucus. Inhale steam from a hot shower several times a day and use a humidifier in your bedroom when sleeping. Alleviating your tooth pain will result from treating the sinus infection.

While sinus infection tooth pain is one specific cause of teeth turmoil, do your best to avoid all types of toothaches. That starts with regular check-ups from your dentist. They will be able to diagnose potential issues, such as cavities or gum disease, which may result in a toothache. Your dentist and dental hygienist can also help you develop a good oral care plan that involves brushing twice a day and flossing daily. Use toothpaste. It fights cavities, prevents tartar build-up and stops bad breath.
