What would you do if you once had a fractured root in a tooth?

I had gone to the dentist and he said a root was fractured so the tooth , he said, had to be pulled. I bought an electric toothbrush and began having toothaches in my molars when waking up. They continued most mornings. I switched and bought a baby toothbrush and would you believe it the toothaches stopped. I feel if I tell him they were hurting he’d want to extract them. But since they stopped hurting I won’t mention it. What would you do?
