Yes if it leaks or wasn't done properly. Somewhere in the world there is the worlds worst dentist and someone has an appointment with him Monday morning.
when you get a filling, they drill some of the tooth which has a cavity and fill it. When you get a root canal, they drill all the way down and take out the nerve of the tooth. Getting a root canal is more painful then a filling.
it depends how deep is your cavity .if the cavity is under your gum there are few chance to keep it because to do a root canal or put a crown is necessary remove all cavity and is contraindicated if your cavity is under your gum or close to the root. If the cavity is too big, sometimes there is nothing that can be done and the tooth has to be extracted. But a first molar is a big tooth that is important for chewing. If you lose it, it will affect the other teeth. Therefore if there is anyway to repair the cavity, by either a filling or a root canal, it would be the best option.
Cranial Cavity, Vertebral Canal
Some pharmacies sell a temporary filling material that may relieve some discomfort until you can see a dentist. It is only temporary, and it does nothing to stop decay or infection. If you do not see a dentist soon, you run the risk of needing a root canal or even possibly losing the tooth.
Marrow cavity does not belong.
Marrow Cavity
You are going to have to have an injection whether you have the tooth pulled or root canal therapy. You really need to talk to your dentist to decide what is the best situation for your tooth. If it is just a case of a filling falling out though you shouldn't need root canal therapy but you might still need an injection for the repair of the tooth if the dentist needs to do any work to fill the cavity.
yes
where canal design bed profile is below ground profile or say when canal is in filling we can provide lining in canal.
Yes, the rectum is in the abdominopelvic cavity. But, the anal canal, which is inferior to the rectum is outside of the abdominopelvic cavity.
internal OS
No. The filling came out because there is something wrong. Either there is decay under or around the filling, which caused it to no longer fit the cavity prep, the bite exerted too much force on the filling breaking it loose, or the filling material used has just worn out. In any case, a new filling needs to be placed, and the cause of the failure needs to be determined and corrected. See your dentist before the tooth requires root canal therapy. That can get very expensive.
