<s>[INST] Hi there, have developed really bad toothache, are on antibiotic & nuromol for three days but not getting much relief. Tooth is a root canal done 10 years ago, have seen a dentist who said it will proberly have to come out, only problem have cycle race on Saturday so if tooth pulled out I cannot compete. Do not want to take to much nuromol as understand not good to be on for to long or is it safe to stay on it for another three days or what are my other pain relief options. regards Peter [/INST] Dear Peter Root canal failure is the common cause. You can ask your dentist to reopen the canal and then continue on antibiotic, you will be relieved of your pain very early and you can participate in your cycle race. Either re RCT or extraction of the tooth can be done on later visit.All the best </s>
