Tooth extraction is done under local anaesthesia/regional anaesthesia/general anaesthesia by a dentist/oral surgeon.
It is done especially in -
Excessively decayed teeth which are not salvageable
During braces treatment to provide room for malaligned teeth
Excessively mobile/lose a tooth
Impacted teeth/half broken tooth
In a simple extraction after the local anaesthesia is administered, the tooth is initially loosened with the help of an elevator and removed with forceps. After local anaesthesia, you may feel numb at the site extraction and no pain is perceived while extraction.
complex cases require surgical extraction under intravenous anaesthesia/general anaesthesia. The dental surgeon makes an incision over the gum and removes the adjoining bone/teeth for complete extraction.
Risks involved in the procedure include-
severe pain, swelling and redness at the operated site
fever with chills and rigours indicating systemic infection
It normally takes few days to recover completely. The application of ice packs over the cheek at least twice daily for 10 minutes will decrease the swelling and pain at the operated site. It also reduces bleeding from the extraction site.
chlorhexidine gargles/mouth wash helps to decrease infection and improves recovery rate.
Even despite these measures, if symptoms do not subside, please feel free to consult your dentist.
