Can a root canal tooth get infected?
A root canal removes the pulp of a tooth that’s been infected or damaged by tooth decay or other injuries. Root canals can save teeth and are considered very safe. Root canal infections aren’t common, but there’s a small chance of a tooth becoming infected even after a root canal is performed.
Can a root canal fail?

What is endodontic access and why is it important?
Let me start with the endodontic meaning: access is the first step in doing a root canal procedure, and it’s one of the most critical aspects of endodontic therapy. If you successfully prepare the tooth you’re working on to give yourself proper access to the root canal system, you’re improving your prospects for success immeasurably.
Where is the access cavity for a molar root canal?
First molars. The access cavity should be rhomboidal in outline, and positioned in the mesial two-thirds of the tooth. The palatal canal entrance is the largest canal and is located in the middle of the palatal half of the tooth and is usually the easiest canal to locate due to its size and position.
How do you prepare the access cavity for endodontic treatment?
Figure 2: Access cavity of a lower first molar; note the three canal orifices are connected by developmental (dark) lines. Access cavity preparation may be divided into four stages: Preparation of the tooth for endodontic treatment Removal of the roof of the pulp chamber and coronal pulp tissue Creating straight line access.
Where are the buccal and lingual canals on a molar?
(b) Access cavity and radiograph of a lower first molar with four root canals, note that the buccal and lingual canals can be found on either side of the mesial to distal mid-line (yellow line) of the tooth.
