Why when I have rhinosinusitis do I feel like I have a toothache? This question is common to those who, at least once in their lives, have been affected by this disease popularly known as sinusitis, an infectious bacterial process that inflames the cavities around the nasal passages.

The sinuses are aerated cavities inside the bones that are located on the side of the nose or on the cheekbones. Inflammation of the sinuses, caused by rhinosinusitis, occurs when the nasal cavities become swollen and inflamed.

Thus, the sinuses cannot drain the mucus, which can lead to accumulation and, consequently, pain. It is an acute discomfort, sometimes excruciating, because the secretion is retained in one of the sinuses or in all of them. But what is the relationship of these symptoms with the dental arch?

The roots of the upper molars are very close to the sinus cavities. Thus, when the sinuses become inflamed and swollen, it is often erroneously believed that the pain originates from the teeth, when in reality it is the result of rhinosinusitis.

Dr. Ana Paula Fiuza Funicello Dualibi explains that, depending on the case, the pain felt in the sinuses is such that it can radiate to lower areas such as the neck, dental arch and jaw. “In addition, rhinosinusitis can cause headache, pain or facial pressure, nasal obstruction or congestion, purulent nasal discharge, fever, halitosis, earache or pressure in the ears, cough and fatigue, among other classic symptoms of the disease”, he details.

We have already entered winter and at this time the occurrence of respiratory and infectious diseases is common. During the coldest months of the year, the most common diagnoses are allergic rhinitis, asthma, rhinosinusitis, exacerbations of chronic bronchitis, COPD (chronic obstructive pulmonary disease), pulmonary emphysema and pneumonia, in addition to flu and colds.

During this period, low air humidity, sudden changes in temperature and increased air pollution are common, which are worrying factors for those suffering from chronic respiratory diseases.

In addition, on cold days, people tend to spend more time indoors, with little ventilation, which favors the triggering of respiratory diseases and also the transmission of flu and colds and other bacteria and viruses, such as those responsible for rhinosinusitis. The disease can be triggered after a viral infection, for example, which opens a door for the entry of pathogens in the body, which has become more vulnerable due to the infectious action. “Infections are like an invader who enters your house, causes damage and leaves the door open for the entry of strangers”, explains Dr. Ana Paula didactically.

Some simple measures can help prevent complications at this time of year, such as avoiding closed and unventilated environments, washing your hands well, protecting your mouth when you cough, drinking plenty of water, and preventing dust accumulation. It is also recommended to eat well, eating fruits and vegetables and betting on a balanced diet.
