Toothache is frequently caused by irritation of the nerve supplying the tooth. The irritation may occur as a result of infection or inflammation caused possibly by tooth decay, or periodontal disease.
The teeth consist of an outer layer or coating made of hard enamel, which protects the living part of the tooth, called the pulp. Between the two is a hard thick layer called dentine, which forms the bulk of the tooth. The nerve and blood vessels supply the pulp.
If the layer of enamel is damaged as it can be by acid formed by plaque (the bacterial deposit that adheres to the outer base of the tooth), it will lead to erosion of the enamel, allowing bacteria etc. to enter.
It is important that this is removed, it usually forms due to poor dental hygiene, but some people are more susceptible to its formation than others because of their type of saliva.
In severe toothache the pain can be referred to the ear, there may also be a headache, sometimes a rise in temperature. It is important to visit the dentist as soon as possible to find out the cause, in the interim period it may be necessary to take a painkiller or try homeopathic remedies called Belladonna or Aconite.
It may be necessary to follow a short course of antibiotics and dental treatment will depend on the cause of the toothache. If the tooth is badly decayed extraction may be the only answer. If this is necessary then try using Arnica after an extraction, as this homeopathic remedy is useful to reduce bruising.
