ROOT CANAL OR EXTRACTION AT Second Trimester

Meron po ba here natry magpabunot or root canal sa second trimester? Kamusta po at okay lang po ba si baby? Nainfect molar ko at nagswell na sobrang sakit at 21 weeks, but dentist told me na mas safe pag 7 mos and sabi naman ng OB ko bawal daw. What should I do?
