Toothache after a cold


A cold or a flu-like infection is mainly caused by a variety of viruses.

It is a disease of the upper respiratory tract.

Typical symptoms include: sore throat, cough, runny nose, hoarseness, and sometimes laryngitis .

But even toothache can be a symptom of a cold. This mainly affects the upper jaw tooth area.

Cause is then usually the inflammation of the paranasal sinuses (sinusitis), which may be accompanied by headache and earache .

In general, it can be said that toothache greatly affects the patient and the cold then feels even worse.


A cold, also known as a flu infection, is a disease of the upper respiratory tract, nose or sinuses, which can sometimes affect the throat or larynx. Typical are the above symptoms.

The cause of the less common toothache often lies in a hitherto unrecognized inflammation of the tooth. It comes through the cold to the fore, because the immune system is weakened and the body tries by all means to combat the influenza infection. The suppressed inflammation of the teeth can then no longer be kept in check. The cold acts as an amplifier of inflammation.

Furthermore, however, a cause is conceivable that does not emanate from the tooth itself. By connecting the nose to the paranasal sinuses, inflammation of the mucous membrane inside is possible. Nerve irritation causes pain.

Furthermore, bacteria can enter the middle ear and cause acute inflammation there (otitis media acuta). Due to the spatially close positional relationship, developing pressure pain can radiate on the maxillary teeth. Even headaches are able to cause toothache. These cause the body to become generally more sensitive to pain.

Accompanying symptoms

In this case, all the symptoms of a cold go along with the toothache. Cough, runny nose, headaches and body aches are typical. A middle ear infection causes pulsating pain, hearing loss or ear noises. Furthermore, it is to be reckoned with an increase in pain during physical exertion and when bending over. These are explained by an increase in pressure in the antrum: the posterior roots in the upper jaw are burdened and the teeth hurt. If the symptoms on the teeth last beyond the cold for more than a week, or if a tooth hurts hot, cold, sweet or sour, it is a sign of tooth root irritation and has nothing to do with the common cold. With this disease is not to joke, you should then quickly visit the dentist.

What to do after a toothache after a cold?

Once the cold has started, toothaches can occur quite quickly. In this case, you can use all the usual home remedies that are available to fight cold and toothache. These include: steam baths with chamomile, mouthwashes with sage tea or tea tree oil, chewing cloves or rosemary leaves and an envelope with chopped onions. In the case of a cold, the body needs sufficient hydration and a lot of rest and relaxation. Even hot baths with essential oils have a soothing effect. For this a proper oral hygiene should be kept.

If the home remedies do not provide relief, a supplemental drug treatment can be considered. Pain medications such as ibuprophen or acetaminophen often fight toothache very well. However, it is important to fix the cause of the cold here. Anti-inflammatory drugs are beneficial. Once the cold has healed, the toothache should also improve. If this is not the case, it is possible that tooth inflammation was the cause. Then no self-medication should be done. A quick walk to the dentist is necessary, otherwise there is a risk of spreading the inflammation!


Since the toothache is accompanied by a cold, its duration depends on it. As soon as this subsides, the toothache should also improve. However, if the pain persists even though you feel fit again, the cause may be that the sinusitis is not completely healed yet. The healing of these often takes a little longer than a headache or cough. However, if the pain lasts for more than a week after the cold, a visit to the dentist should take place so that the actual cause can be treated.

Toothache in the upper jaw after a cold

Especially in the upper jaw occur toothache in the context of a cold very often. Especially if the paranasal sinuses are affected by inflammation. It comes to a filling of the cavity through fluid formation and mucosal swelling, which builds up a pressure. This compresses the nerve and causes pain. The pain is often throbbing and can spread over the cheek. Depending on which sinuses are affected, the pain also radiates to the forehead or behind the eyes.

In some people, it feels like the upper jaw teeth are hurting. This is due to the very close positional relationship between the maxillary sinus and the tooth roots, which are separated only by a very thin layer of bone and mucous membrane. These symptoms should not be classified as "real" toothache, as the teeth are not the cause of these sensations. You can also pretty well separate them from each other.

Pain originating from the paranasal sinuses becomes stronger due to an increase in pressure when bending over the head, toothache not. Furthermore, it is possible that the nerve (superior alveolar nerve), which is responsible for the sensor of the maxillary teeth, is clamped or damaged elsewhere. It runs along the floor of the maxillary sinus and is at risk for sinusitis. Since the brain can not tell where the damage is taking place, it then projects the pain onto the entire upper row of teeth. The middle ear infection radiates in the upper jaw area. The healing of these diseases may take a long time. Although you feel fit again, as cough and runny nose are gone, the toothache then last a few days.

Toothache in the lower jaw after a cold

The teeth in the lower jaw are affected in a cold only in very few cases. Only when sinusitis lasts for a long time and can spread due to lack of treatment, the lower jaw teeth begin to hurt. Since this sensation spreads diffusely over the entire face, here often no exact tooth can be named as causer. In addition, it is possible that an infection from the ear, nose and throat area spreads to the salivary glands. Especially in the floor of the mouth, the submandibular gland (Glandula submandibularis) is located in a very close position relative to the lower jaw teeth. The inflammation of this gland (sialadenitis) causes lower jaw pain, which sometimes resembles toothache. Of course, there is also the possibility of a tooth root inflammation in the lower jaw.
