Pain on the crown
When preparing a crown, the protective hard tooth substance, i.e. the enamel, is removed with abrasives. It is called grinding trauma if the tooth is not sufficiently cooled with water during the treatment. However, irritations also occur because the cold water cools the tooth and the nerve too much.
When inserting a crown, for example a ceramic crown, the tooth is first etched with a high percentage hydrofluoric acid preparation. When chewing, the tooth also hurts if the crown is too high, i.e. if it does not fit properly, 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 are pushed apart. Then the neighboring teeth usually hurt additionally as soon as chewing pressure on the tooth with the crown is applied.
Toothache with a cold
In the case of a cold, the paranasal sinuses, including the maxillary sinus, are filled with nasal secretions and fluid. Since the upper lateral teeth and the canines with their long roots reach to the floor of the maxillary sinus and sometimes even into it, pain can occur. When chewing, the teeth are pushed further into their dental cavity.
At the tip of the root, the nerves and blood vessels enter and exit and are squeezed between the chewing pressure and the fluid in the maxillary sinus. In addition, gum inflammation can occur when you have a cold. With this type of inflammation, any kind of touch hurts, which cannot be avoided when chewing and eating.
Duration of toothache
Toothache when chewing should only last as long as you chew.It is impossible to give a time how long such pain lasts, and when it should be gone again. It is important to find out the cause of this pain and treat it. Physiologically it is normal that it hurts when you bite a hazelnut, for example.
The jaw and teeth are not designed for this. If the pain persists only when chewing, the cause can be one of the ones described below. However, if it occurs spontaneously while chewing and does not subside after eating, it may be that something is broken, broken or dislocated. Pain while chewing and especially pain that lasts longer should definitely be examined by a dentist.
