Toothache can be caused by several factors.
Toothaches, frequently caused by caries reaching the tooth nerve, are characterised by a strong, throbbing pain. This pain tends to worsen when lying down, particularly at night, making it challenging to identify the tooth involved. It may temporarily ease after taking a painkiller.
Toothache can also be attributed to periodontal disease. In this case, the pain is gravative, becoming more pronounced when chewing. Unlike other cases, the affected tooth is easily identifiable and may exhibit signs of mobility.
Toothache can also result from dysodontiasis, the improper eruption of a tooth, typically the wisdom tooth. This condition occurs when a part of the tooth remains covered by the inflamed gum, leading to pain. This is called pericoronitis, characterised by well-localized pain, redness, and swelling of the gum surrounding the tooth, often accompanied by pus. The pain may radiate to the throat and ear, making chewing and swallowing difficult. In some cases, it can also cause fever and swelling of the lymph nodes.
