My wife had her left lower wisdom tooth extracted about 10 days ago. The tooth was coming out abnormally & had all its roots curled up. Hence, the oral surgeon had to slice the tooth & take it out part by part which took quite a lot of time. However, now after so many days of extraction, she has developed teeth sensitivity in her front 4 teeth, this infact has spread to the upper teeth as well. Even after repeated betadine gargles & rinsing, it doesn't seem to go away. Can anyone suggest here what should be done ?
