A few months ago I had pain which I thought was sinus. Dental x-ray showed infection on tooth which already had onlay. Think UK name of tooth is UR4 (first upper pre-molar). Root canal. Endo told prostho not to use post - but prostho insisted on gold post - now more pain. Endo started me on co-amoxiclav and will see me tomorrow for CBCT scan. I'm looking at an extraction, aren't I? 😩
