crowns

I have seen a lot of post on this forum that complain about pain after having a crown put on or having pain under the crown after having them awhile.  Some even think that they may have abscesses growing in the roots/canals of the crowned tooth.  I thought that the whole point of a crown was to protect damaged teeth especially from bacteria that will lead to abscesses.  Others say that their crown does not fit right.  Has anyone had a real great experience with their crown?  How long are crowns suppose to last.

i have one crown for a few months that has a sharp edge and since the tooth is badly cracked underneath it cant be removed so i hope they can file it to remove the ledge that sticks out over the back of the tooth. i have had another crown for 30 years without a single problem. just because a tooth has a crown things can still happen like root fractures but without a crown chances of loosing a cracked/root canaled tooth dramatically increases. if you crown a molar get gold. its much stronger and has less impact on surrounding teeth and gums. it will also last much longer. remember most people post here because they have a problem the majority of people dont have problems and therefore have no reason to post on a dental forum.
