Sorry to hear about that broken tooth.... Hard to say if you should continue to oil pull or not. If it were me, I´d continue: but honestly don´t know if this would be a good thing or not. After the oil pull, I usually brush teeth with a 1:1 mixture of himalayan Sea Salt and Sodium Bicarbonat, which IMO works at re-mineralising and helps to keep the bacteria down.
Best of luck with your decision.
