Endodontist

Usually because something about your case is more demanding than routine: complex or calcified canal anatomy, a molar with an unusual configuration, previous treatment that needs redoing, a post that must be removed, or pain that has been difficult to attribute to a specific tooth. Referral reflects a judgment that the case will be handled better with specialist equipment and repetition, instead of any deficiency on your general dentist's part.

Typically yes, reflecting additional training, magnification, imaging and the time complex cases require. Whether that is worthwhile depends on the case. For straightforward anatomy, general practice treats root canals perfectly well. For a molar with difficult anatomy or a retreatment involving post removal, the specialist route often has a better chance of success, and a failed attempt followed by referral usually costs more overall than referring at the outset.

Sometimes, and a second opinion is reasonable where the tooth matters and the reasoning is not clear to you. Endodontists can occasionally treat anatomy that could not be negotiated elsewhere, retrieve separated instruments, or manage perforations. What they cannot overcome is a tooth that is not restorable afterwards or one with a vertical root fracture. Ask specifically which of those applies, because those are the limits, not the canal work itself.

Retreatment works through the crown: existing filling material, and often a post and crown, are removed so the canal system can be cleaned and resealed. Surgery, apicoectomy, approaches the root tip through the gum, removing the tip and sealing the canal from outside, and usually leaves the existing crown undisturbed. Retreatment is generally attempted first where feasible; surgery is used where access from above is not possible or has already failed.

Yes, and promptly. The endodontist completes the canal treatment but the definitive restoration, usually a crown or onlay on a back tooth, is normally placed by your general dentist, and it is not optional. A root-treated tooth left in a temporary filling is at real risk of fracturing or being recontaminated. Book that restoration appointment when you book the endodontic treatment instead of afterwards.

Operating microscopes for magnification and illumination, ultrasonic instruments for locating and negotiating difficult canals, and CBCT for three-dimensional imaging are the main distinguishing tools. These make previously invisible canal anatomy, separated instruments and root fractures identifiable in ways a standard setup often cannot, which is why complex or previously failed cases are commonly referred.

Often one to two, though it depends on the complexity of the canal anatomy, whether infection is present that needs time to resolve, and whether retreatment or surgery is involved. Ask at the outset how many appointments are anticipated for your specific case instead of assuming a single universal number.

Yes, and a good one will, since restorability is assessed before treatment begins specifically to avoid starting canal work on a tooth that cannot ultimately be restored. Ask directly whether the tooth has been confirmed restorable and what the specific basis for that assessment is: remaining tooth structure, fracture pattern, periodontal support.

Some tenderness for days afterward is common and expected as inflamed tissue around the root settles. Pain that is severe, worsening, or persists well beyond the expected healing window is not typical and should be reported promptly, not assumed to be normal. It can indicate missed canal anatomy, a crack, or a restoration issue.

Retreatment is the first option considered where the tooth remains restorable and the cause of failure can be addressed: removing the old filling material and often a post and crown to clean and reseal the canal system. Where retreatment is not suitable, apical surgery or extraction with replacement planning are the alternatives, and which applies depends on the specific cause of failure.

No: the large majority of endodontic referrals are for nonsurgical treatment or retreatment, which work through the crown of the tooth instead of surgically. Surgery (apicoectomy) is reserved for cases where conventional retreatment is not possible or has already failed, and it is a distinct, less common pathway instead of the default outcome of a referral.

Often yes, in jurisdictions and insurance arrangements where direct access is permitted. A general dentist's initial assessment and radiographs are still valuable groundwork. If you have persistent unexplained dental pain, calling an endodontic practice directly to ask about their intake process is reasonable, not assuming a referral is mandatory.
