About Pain

Reversible pulpitis
Symptoms include transient pain or sensitivity resulting from many stimuli, notably hot, cold, sweet, water and touch. The pulp is still considered to be vital. This means that once the irritant is eliminated, usually by removal of decay and the placement of a filling, that the pulp will return to its normal, healthy state.

Irreversible pulpitis
Symptoms associated with irreversible pulpitis may include dull aching, pain from hot or cold (though cold may actually provide relief) lingering pain after removal of a stimulus, spontaneous pain, or referred pain.

Apical periodontitis
apical periodontitis can be symptomatic or asymptomatic at different stages of their development and progression.
Most cases of apical periodontitis are asymptomatic.Symptomatic apical periodontitis may appear in a tooth with previous asymptomatic apical periodontitis.
This may either reflect a natural shift in the balance previously established between the bacteria and the host or occur in response to Root-Canal-Treatment (endodontic flare-up).

Acute apical periodontitis
pain,tenderness to bitting pressure, percussion or palpation as well as swellings.The symptoms may vary from mild to severe.

acute apical abscess
spontaneous pain, tenderness of the tooth to pressure, pus formation and eventual swelling of associated tissues.

Pain after a root-canal-treatment
Post-operative pain and/or swelling resulting from bacterial, mechanical or chemical irritation to periapical tissues by Root-Canal-Treatment.
It is normal to experience some discomfort for a few days after root canal treatment. A post root-canal-treatment pain should be expected if the tooth was seriously painful before the procedure. The tooth might feel tender when biting or chewing and may even appear to feel loose. These symptoms are can be said as acute apical periodontitis started by Root-Canal-Treatment.
