Is it probable that root canal packing can “leak” and infect a salivary gland? My son had two unilateral salivary gland infections in the space of a few months. The hospital CT and dental x-rays didn’t show any problems. We’re not sure why he keeps getting these recurrent infections. (He’s had two root canals with crowns done on his lower jaw just above his infected gland.) Thank you.

It’s possible that a tooth infection could spread to a salivary gland but for that to happen, the tooth would have to be infected. You mentioned the tooth had a root canal treatment so a tooth with this procedure wouldn’t be infected if it healed properly in the first place. And, if it didn’t heal as it should have, this would show in the x-rays.
So the best answer would be “no.” This is because the x-rays didn’t display any tooth infection and there wasn’t any root canal failure so nothing could spread to the salivary gland.
