There’s a chance of endometrial lining growing back even after the procedure, and there’s no sure way of completely removing it forever. But usually, it takes years for the lining to grow back.  Sometimes, there’s a chance the ablation may fail right after the procedure is done too. Several factors are involved, such as age, history of tubal ligation, and uterine size. Some people opt for getting another endometrial ablation procedure done.
