A root canal is a procedure that extracts decayed tissue from inside a tooth, reshapes the canal and replaces it with strengthened filler. There are a number of reasons a root canal may be necessary, including dental injuries, severe decay and infection or inflammation in the tooth pulp. When left untreated, these problems can cause extensive damage to the tooth structure.
Root canals can typically be completed in one visit, although more extensive cases may require another appointment. You will also be able to drive yourself home after the appointment.
