Extraoral diseases such as dental caries, dental abscess, erosion of tooth enamel, gum diseases, impacted teeth, falling fillings, and sinusitis may be the causes of toothache.

• Tooth caries changes the type of pain depending on the depth of the caries. In mild and early bruises, pain occurs depending on the stimulus (eating and drinking), particularly with sweet foods. In such cases, filling can be done to prevent pain.

• Tootache in deep dental caries is often a very severe throbbing paing. In case of an inflammatory condition such as abscess, there can be swelling large enough to be noticeable from the outside. There may be sensitivity to hot-cold and increased pain when pressing against the tooth. Endodontic treatment (root canal treatment) can be applied to these types of pain.

• The type of pain that occurs in gingival recession due to erosion of tooth enamel, tooth cracks, and gum diseases is sensitivity to heat-cold and sweet-sour. In such cases, it is often enough to apply desensitizing preservatives to the teeth.

• Extraoral diseases such as sinusitis may cause widespread and reflected pain in the maxillary posterior teeth. Sometimes, the problem in the lower jaw molars can be felt as pain reflected in the ear. In such cases, careful and accurate diagnosis is crucial.
