Pain after stomatological treatment is a frequent but marginalized problem. It is an often effect after the anaesthetics stop working. This type of pain may last from one day to even 2-3 weeks. The reason of feeling pain is a mechanical injuries of tissue during the surgery or irritation of strongly nerved tooth pulp or cementum fibers. The method is to deliver painkillers and ant medicines for the time of regeneration of damaged tissus. Thanks to this type of medication the patient doesn’t feel any pain and discomfort related with the dental treatment. Adventages of using painkillers are: no pain after the anaesthetics activity time, shorter time of regeneration of damaged tissues, reduction or elimination of hypersensitiveness after the treatment. In addition to painkillers there is a possibility of using Bioptron lamp therapy which makes the regeneration time shorter and reduces pain and swelling.
