You said that, that white spot may work it's way out trough the sinus, what that means ? Or if it stays there and don't go anywhere, I should have a sinus surgery to get it out ? I can try to go to the ENT dr. with these x-rays and ask him to look at the ct scan again. And there comes my question again , would the dental ct scan show better about this white spot ? or a different dental x ray ?
