What Happens When Root Canal Treatment Fails
Saving the tooth usually follows a two-step path.
Why a problem returns years later
Root canal treatment cleans, shapes and seals the space inside the root. Canals are not always a single straight tube — there can be side branches, joining canals and sharp curves, so parts may not have been cleaned completely the first time. The other route is later leakage: if bacteria seep past the margin of the filling or crown, the canal is recolonised, and a fractured crown, a lost temporary filling or new decay does the same. Symptoms are typically pain on biting, a recurring small swelling on the gum, or a lesion seen on a radiograph with no complaint at all.
Retreatment: redoing the root canal
In retreatment the tooth is re-entered, the old root filling removed completely and the canal system cleaned and shaped again; working under magnification can reveal an extra canal missed the first time. The canals are then disinfected, refilled and the restoration renewed. It is tried before surgery because the source of the problem is usually bacteria inside the canal, and treating the source directly makes more sense. It takes longer than the first treatment and often needs more than one visit; a crown may have to be removed or drilled through, meaning a new crown afterwards.
When apicoectomy is considered
- When retreatment is impossible or has not sufficed
- A separated instrument or blockage that cannot be removed
- A post whose removal would endanger the root
- A periapical lesion that does not shrink after retreatment
- A few millimetres of the root tip are removed and sealed
- It cannot be used where there is a vertical root fracture

Choosing a Filling Material: What the Decision Rests On
Choosing a filling material is not merely an aesthetic preference. The size of the cavity, which tooth it is in, the strength of the chewing forces and whether moisture can be controlled all shape the decision together.
Composite: today's standard
Tooth-coloured, it bonds chemically to the tooth, and that bond allows less sound tissue to be removed. It sets immediately under a curing light, so no waiting is needed. Its limits appear in very large cavities and in subgingival areas where moisture is hard to control.
Onlays and inlays: between a filling and a crown
Where the loss of tooth substance is too great for a filling to carry but not so great as to require reducing the whole tooth for a crown, an onlay is used. Made in a laboratory and bonded to the tooth, it supports the remaining walls and prevents the tooth splitting under chewing. In back teeth it is safer long term than a very large composite.
How many times can a filling be replaced?
Each replacement removes a little more tooth tissue, so a tooth cannot be filled indefinitely. Once the remaining walls are thin enough to flex under chewing, the next step is an onlay or crown rather than another filling. Making that transition in time prevents the tooth being lost to a vertical fracture.
