Will this require that I get a root canal as the dentist indicated it might, and shouldn't they have seen this with my previous set of ex-rays last year? Btw, I have no discomfort whatsoever. Thank you for your responses.
Is this a dentist you have seen regularly, or is this a new dentist to you? By "leaking", I'm not sure that the dentist means decayed. You should have this clarified. If there is decay at the margin of the crown(s) on the cheek or tongue side of the crown sometimes it can be removed without taking the crown off. If the decay is in between the teeth there is no way to access the decay without removing the crown and excavating the decay.
It is possible that the decay formed in the last year. But it is sometimes easy to miss decay at the margin of a crown on x-ray unless the angle of the x-ray is just right. Sometimes it just doesn't show, and it's no fault of the dentist.
If however you are not sure you trust this dentist, I would recommend a second opinion.
