The most common cause of pain while chewing can be traced back to a damaged tooth. This is mostly attacked by tooth decay, which fights its way through the healthy hard tooth substance and migrates towards the tooth pulp. Tooth decay is bacteria that arise from plaque and process sugar. The end products of this processing process are organic acids that demineralize the tooth, i.e. break down the hard tooth substance. This creates a hole. This usually causes pain even if there is no chewing load, when the caries is already more advanced.

At Chewing force load But even "normal" tooth decay can lead to pain, as food components press on the affected area. Particularly sweet and acid Foods, an example of which would be gummy bears, cause toothache. When the strain subsides, the pain is no longer present. The causes of tooth decay are primarily in the poor oral hygiene, whereby the plaque is not completely or partially removed and thus the bacteria optimal breeding ground is offered.

But also one poor diet, by many sugary and acidic foods, or a possible genetic predisposition, promote the development of caries. If the first symptoms are ignored, the tooth decay will progress and also affect other areas of the masticatory system. The further stages can also be considered as a cause of toothache when chewing.


Is pulpitis present (Dental nerve inflammation) or if the tooth nerve is already dying or dead, pain can be increased when chewing. It is not only important whether there is food, but also how firm it is and whether it is warm or cold. In pulpitis, for example, the pain is much worse with cold food than with warm food.

Pulp necrosis

If the tooth root has died, however, there may also be freedom from pain, as the tooth root contains the important nerve fibers, which then no longer allow forwarding. The bacteria can progress so far that the tooth support system can be affected, so that at the end of the Tooth loosened is, or has to be pulled. If, accordingly, pain occurs when chewing, a check-up at the dentist is advisable in order to diagnose the caries as early as possible.

Toothache after a filling

In addition to the cause of tooth decay, a tooth that has already been filled with a tooth can also trigger toothache. The pain is in this case rather pulling, especially present with hard food and subsided again after a certain time. This sensitivity is due to the fact that the dental nerve was severely irritated due to the treatment and needs a certain regeneration time. However, these symptoms should subside, otherwise the filling material may not be correctly connected to the tooth, which means that the filling acts like a spring when chewing and has to be replaced.

Toothache after a root canal treatment

Even after a root canal treatment, there may still be pain in the neighboring teeth. Starting from this position, toothache when chewing after a visit to the dentist is not uncommon, as the tooth is irritated and has to come to rest. When a tooth is drilled, heat, pressure, and high forces are exerted on the tooth nerve, which must recover from the irritation.

Toothache under a crown / bridge

Toothache while chewing can also occur under a crown or bridge. If the crown is newly inserted, it is likely that the jaw joint will have to get used to the position of the teeth again. If the symptoms persist, it is necessary to check the bite again (occlusion), possibly with grinding back the crown. Caries or inflammation of the pulp (pulpitis) are also possible triggers for toothache under a crown.

Misalignments of the teeth

Another possible cause of toothache when chewing is when the teeth are not correctly matched to one another and do not mesh optimally when chewing. These Pain usually spreads widely and can even affect the temporomandibular joint, as it can become inflamed with permanent incorrect loading and cause pain with any movement of the mouth. Too high a filling or a tooth crown can prevent the correct bite. This is particularly possible with larger interventions such as a bridge, an implant or a full denture. But even in this case you have to wait a certain amount of time, since you have to adapt physically and mentally to the new, unfamiliar situation in your mouth.
However, if you continue to experience chewing discomfort after a long period of time, it is advisable to have another check with your dentist. He or she can renew the filling or correct the new denture until it has found the right fit and the normal bite is guaranteed, so that the toothache when chewing subsides.


Bruxism is a common misuse nowadays. This is an unconscious clenching and grinding of teeth, usually at night. This will make the Teeth exposed to high forces and also the temporomandibular joint is affected, so that by the persistent improper loading, Pain when chewing may occur. A tooth that is permanently incorrectly loaded can die because the strong pressure damages the tooth nerve.

In addition to the causes mentioned, "sinusitis" (Sinus infection), to Pain in the teeth and thus also lead when chewing. The paranasal sinuses include the maxillary sinuses, the frontal sinuses, the ethmoid cells and the sphenoid sinus. The disease is usually associated with fever, headache and general depression. Viruses, bacteria or allergies are the most common triggers.

Is the Inflamed maxillary sinus, this painful stimulus continues to the teeth. Especially when chewing, the pain is aggravated due to the pressure sensitivity in the upper jaw. The proximity of the roots of the molars to the maxillary sinus is also important for this interplay of pain.

Concomitant symptoms

Noticeable symptoms of chewing pain are a Crunching or cracking in the jaw joint. The joint may be overloaded or irritated. When the joint disc is already worn out, the bones rub against each other, causing a sharp pain and a radiating pain to the teeth. This accompanying symptom is often seen in patients with Bruxism, i.e. those who constantly grind their teeth and in which the articular cartilage is already damaged. It can also too Headaches and migraines come and indirectly to Loss of appetite. This is an inverse protective mechanism used by the body to escape the pain.

If the cause is too much filling, another symptom is the lack of contact with other teeth. If the filling is too high, one speaks of an early contact. On the one hand, one tooth receives too much chewing force, on the other hand, the jaw joint is steered into the wrong path of movement. The headache described above can also be caused by a Sinusitis come. If you have a sinus infection, the maxillary sinuses are also affected. On the one hand, the cold leads to a feeling of pressure and headaches, as the cavities are filled with too much nasal secretion and fluid. On the other hand, the nerves of the upper molars are squeezed by the weight of the liquid, especially if there is additional pressure from the other side while chewing.

Toothache after a root canal treatment

Most of the time, there is already pain before the root canal treatment, which does not go away immediately after the treatment. In root canal treatment, the tooth nerves are torn off from the large nerve at the tip of the root.This rupture has to take a few days to recover. Since every tooth is individual, one can never predict that the treatment will be a success. Some of the root canals are so curved that bacteria cannot be completely removed from them. Germs can therefore still remain in the tooth and continue to cause pain. The pain can also come from a filling that is too high or too wide, which is placed at the end of the treatment.

Toothache after a filling

Pain after a filling is not uncommon. On the one hand, an injection is given before the filling therapy so that you do not feel any pain. As soon as the anesthesia wears off, pain may reappear. They come from the fact that a large part of the damaged hard tooth substance is removed, which actually serves as protection. Depending on how deep the filling goes and how far it protrudes to the nerve, the tooth pulp is irritated. Another reason is that the tooth is additionally irritated during the treatment from drilling and grinding and from the cold water. The most common reason is too much filling, or a filling that was placed too close to the neighboring tooth. The first contact comes with the filling when chewing. The entire chewing force is transferred to a single tooth and its ligaments.

Toothache only when eating hard foods

There can be several reasons why one or more teeth hurt, especially when chewing hard foods. If you speak of hard food, it is still “softer” than the hard tooth substance itself, otherwise the tooth would break. But if the tooth is weakened by caries, it gives way to the pressure. Tooth decay makes the tooth porous and hollow. If something hard presses on the chewing surface, this pressure is transferred to the nerves via the softened enamel and the even softer dentin. The cause of the pain can also be am Teeth-supporting apparatus lie. When chewing, the tooth is pressed into its tooth socket. With hard food that doesn't just give way, all the more so.

The fibers that hold the teeth are stretched. In the event of inflammation of the gums and the remaining periodontium, this reacts to the heavy load with pain. The pain can also arise in the temporomandibular joint. If the food is so hard that it cannot be easily bitten into, the jaw joints are stressed unevenly. If you only chew on one side, the opposite joint is lifted off its hinges. The pain arises from the fact that the bones of the joint head and socket rub against each other. The pain pulls from the temporomandibular joint and radiates into individual teeth. Often it is not possible to pinpoint the pain at all.

Pain in the crown

When preparing a crown, the protective tooth structure, namely the Enamel removed. One speaks of one Grinding trauma if the tooth is not sufficiently cooled with water during the treatment. However, it also happens Irritation because the cold water is too cold for the tooth and nerve. When inserting the crown, for example a ceramic crown, the tooth is first etched with a high-percentage hydrofluoric acid preparation. The tooth also hurts when chewing if the crown is too high, i.e. if it does not sit correctly or if the tooth with the crown comes into contact with the opposing tooth too early. If the crown is too close to the neighboring tooth, they will be pushed apart. Then the neighboring teeth usually also hurt as soon as chewing pressure comes on the tooth with the crown.

Toothache with a cold

When you have a cold, the sinuses, including the maxillary sinus, filled with nasal secretions and fluid. Since the maxillary posterior teeth and the canines with their long roots protrude to the floor of the maxillary sinus and sometimes even into it, pain can occur. When chewing, the teeth are pushed further into their tooth socket. The nerves and blood vessels enter and exit at the tip of the root and are squeezed between the chewing pressure and the fluid in the maxillary sinus. It can also occur with a cold Inflammation of the gums come. With this type of inflammation, any kind of touch that cannot be avoided while chewing and eating is painful.

Duration of the toothache

Toothache while chewing should only last as long as you are chewing. One can no time how long such pain lasts and when it should be gone. It is important to find out the cause of this pain and treat it. Physiologically, it is normal for it to hurt when you bite a hazelnut, for example. The jaw and teeth are not designed for this.If the pain only persists while chewing, the cause may be one of the reasons described below. But if they occur spontaneously while chewing and don't fade away after eating, something may be broken off, broken or dislocated. Pain when chewing, and especially pain that lasts for a long time, should definitely be examined by the dentist.


Depending on the cause, there is one different treatment to strive for. However, if you experience pain symptoms, a dentist or in the case of inflammation in the head area ENT doctor or General practitioners.

If the cause is dental, the dentist can treat the tooth decay, replace the filling, grind in the crown or rework the full denture so that a correct bite on healthy teeth is guaranteed. Until treatment can be pain medication, such as Ibuprofenor Paracetamol, used to relieve pain. Also common home remedies, such as Cool, Clove oil, Rinse with Camomile tea or one disinfecting mouthwash, as Savoy cabbage leaves can be used as a means of relief. However, even in this case, the cause is not combated, only the symptoms are alleviated.


Toothache that occurs while chewing are No rarity and affect many people. On average, everyone suffers from a cold at least once a year, which can spread to the paranasal sinuses and must therefore be considered as a trigger for toothache.

A good oral hygiene significantly reduces the risk of tooth decayso that a toothache triggered by this or pain that may arise as a result of the treatment can be well controlled and prevented. Toothache is intensified or triggered by the high forces that act when chewing, but which are essential for chopping up daily food, but this can be treated well and efficiently with a visit to the dentist, so that you can enjoy eating the morning cereal again to get.
