HI
your crumbled tooth seems to have draining Pus from the case history you have cited. broken down (Crumbled teeth), often leads to pulp exposure and subsequent pulpal and peri- apical inflammation (i.e., inflammation in the socket of the teeth around the tips/ apices of teeth). During such inflammation, Abscess formation takes place. AND IT IS THE FACT THAT LOCAL ANESTHETICS LIKE
NOVOCAINE OR ANY OTHER DOESN't WORK SOMETIMES IN PUS LADEN AREA.
You haven't mentioned which teeth and in which jaws, as it is related to area/ techniuque of anesthetic injecton. if you don't wish for a General Anesthesia, you can try the following, for
Local Anesthesia only to become effective
1) take antibiotics like
AUGMENTIN 625 for two times a day for three days to ward off the infection, so tha LA can be effective
2) Ask for around two shots of Local anesthesia and wait for half an hour
3) ask the
dentist to use other alternative techniques of anesthesia like, local infilteration/ pulpla and Periodontal blocks, Nerve Blocks etc
4) Lastly if nothing works out, see a
second opinion from another dentist
