I went to dentist yesterday. Took xray of molar and showed infection around tooth. Nothing was visible to the naked eye. Since I am goin away for a week, they prescribed me clindamycin (150mg 3x a day). 36 hours into antibiotic treatment, pain is 90% subsided, however there is now a bubble next to the tooth. Is this normal? Is this just the infection getting "out"? If so, what happens when it pops? Thanks.
