Ok. X-rays are not that good, it mostly is guesswork. But I remembered other indicator. Does it hurt when you push the roots from outside at your face? Also does it feel mushy or liquid-ly at some point. I had totally painless bag of puss under my eye for 10 years. Only when got infected for the second time, it started to hurt and needed a canal, via which the said puss squirted out. It is like totally new now, did not even need a crown.
