Reply:Temporary crowns can last a fairly long time, if you are not biting hard on them. Permanent are much better and last for years and years, while a temporary at best can go a year. That's not saying that they can't break or have something happen, but barring unforeseen circumstances, permanent can be a lifetime, while temporary can be a month or two to a year or two.
