|As a rule, tooth pain or toothache associated with the pain appearing around the teeth or jaws. In the majority of cases, toothaches are induced by either tooth or jaw problems, like a cavity, an exposed tooth root, a cracked tooth, gum disease, disease of the jaw joint, or spasms of the muscles used for chewing. The rigour of a toothache can vary from mild to chronic and agonizing. Besides, the pain may be deteriorated by chewing or by extreme cold or heat. A careful oral examination, including dental x-rays, can assist in determining the cause, whether the toothache is coming from a tooth or a jaw problem.|
Sometimes happens that pain around the teeth and jaws comes as the symptoms of diseases of the heart, for example such as angina or heart attack, or of the ears, such as inner or external ear infections, and sinuses, like air passages of the cheek bones. The pain of angina, which is because of the poor supply of oxygenated blood to the heart muscle owing to narrowing of the arteries, usually happens in the chest or arm. Nevertheless, in some cases of angina, a toothache or jaw pain, are the only signs of heart problem.
In addiction, infections and diseases of the ears and sinuses can also cause toothache. Therefore, evaluations by both dentists and doctors are sometimes needed to identify medical illnesses causing toothache. Or else the common dental causes of toothache include dental cavities, dental abscess, and gum diseases, irritation of the tooth root, cracked tooth syndrome, temporo-mandibular disease, impaction, and eruption.
However, the most common cause of toothaches is dental cavities (holes in the two outer layers of a tooth, called the enamel and the dentin). The enamel is the outer white hard surface and the dentin is the yellow layer placing just beneath the enamel. Both layers build the protection of the inner living tooth tissue called the pulp. Pulp is the tissue where the blood vessels and nerves are. Some certain bacteria in the mouth change simple sugars into acidic solutions. The acid softens, and, together with saliva, destroys the enamel and dentin, creating small holes, or cavities. In actual fact, small, shallow cavities are not that aching and may go overlooked by the patient. As for the larger deeper cavities – they can gather food particles. As a result the inner living pulp of the affected tooth gets irritated by bacterial toxins or by foods that are cold, hot, sour, or sweet, provoking toothache.
Traditionally, treatment of a small and shallow cavity involves a dental filling, using amalgam, composite resin or glass ionomer cement. Nevertheless, in the case of a larger cavity, an onlay or a crown is capped on the affected area. Treatment of a cavity that has permeated deep enough and injured the pulp needs either a root canal procedure or extraction of the affected tooth. Injury to the pulp can cause death of pulp tissue, resulting in tooth infection, or dental abscess. The root canal procedure involves removing the dying pulp tissue, therefore avoiding or removing possible tooth infection, and replacing it with an immobile material. This procedure is used in a challenge to save the dying tooth from extraction and is very aching.
