In the case of "dolor post extractionem" (infection-based pain after an extraction), the blood clot disintegrates in the alveola as a result of bacteria population. The result is an empty alveola, sometimes accompanied by a bad odour and severe, dull pain. Therapy consists of bacteria combat. Bacteria responsible for complicated wound healing are fought with disinfecting insertions. Rinsing and medicinal inserts are repeated daily until symptoms have disappeared. Analgesic agents or antibiotics are prescribed if necessary.
