Acute pulpitis is the intense inflammation of the tooth pulp. Acute pulpitis comes with severe pain, which lasts a few minutes (or can also be continuous) and is caused by a stimulus such as cold or warm. Puplitis is commonly characterized by continuous pain even after the cessation of the stimulus action. In advanced stages (acute purulent puplitis), the pain becomes unbearable. Sometimes, it may even occur automatically, without a cause or stimulus.
The cause of pulpitis may be tooth decay, an injury to the tooth from an accidental fall or some work done on the tooth (filling, grinding to get a crown etc). In its early stages, acute pulpitis may not be damaging to the pulp, but if it’s not treated properly, purulent pulpitis – detrimental to the pulp of the tooth – may appear. In the very early stages, acute pulpitis is a condition theoretically reversible. In most cases, the treatment of choice involves the removal of the pulp (root canal therapy).
