Causes

The most common cause for an infection of the pulp (pulpitis) is a deep cavity. This enables bacteria to enter the tooth's interior and infect all of the soft tissue. However, other irritants can also lead to such an infection, such as: mechanical strain (blows, shocks, consistent grinding) and thermal irritation. In the course of time, these irritations add up until they result in an infection. The mechanical strain can also lead to fine tears which make it easier for bacteria to enter the tooth.

The tooth can react by becoming very sentitive to heat or cold or it can develop a lasting ache. The results of an infection can also remain undetected until they are discovered during the course of a dental examination.If this infection is not treated, the bacteria can bring on the purulent destruction of the jawbone. Other organs can become infected, resulting in sickness and a weakened immune system.
