A toothache is a pain felt by one or more teeth. It can be caused by a variety of issues, such as tooth decay, cavities, gum disease, infection, abscesses, and trauma to the mouth. A root canal may be needed if an infection is present or if there has been severe damage to the tooth.

Feeling pain in the teeth can be related to other health issues as well. For example, if you experience ear pain and you have a tooth that is decayed or infected, the infection may spread from the tooth into the sinus cavity and cause severe pain in the forehead and cheeks in addition to your teeth. This is commonly referred to as sinusitis. When the sinus cavity becomes inflamed, it may cause additional pain in your ears and overall discomfort in your face. This type of pain may also be present in your nose, throat, and eyes.

If you are experiencing severe pain, there may be an underlying issue that needs treatment. Schedule an appointment at our dental office.


The sinuses are air-filled spaces within the bones of the face. There are four sets of sinuses, one set on each side of the face. The sinuses produce mucus, which drains into the nose through small openings.

Sinusitis is the inflammation of nasal passages caused by allergies, colds, or infections of the nose. When sinuses become inflamed, they can swell and put pressure on the sinus walls. This can cause pain in the upper jaw and even headaches. The pain can also spread to the cheeks, forehead, and eyes.

If these symptoms occur more than 12 times per year for at least three months without improvement with treatment, it is referred to as chronic sinusitis. Chronic sinusitis is more common in people with allergies, asthma, thick mucus membranes, and structural issues such as crooked teeth or a misaligned bite.

A sinus infection occurs when bacteria infect the sinuses, which are hollow cavities in the skull that are connected to the nasal cavity. It can cause pain, pressure, congestion, and drainage in the nose or down the back of the throat.

To treat it, your doctor will likely prescribe antibiotics to fight the infection. In cases of severe sinusitis, you may need surgery to clear out your sinus passages.

If you have chronic sinus infections that last longer than a few weeks, you may have allergies or a deviated septum that is causing your issues. In these cases, treating the underlying condition may get rid of your symptoms.
