Root Canal or Extraction? How the Decision Actually Gets Made

The choice between a root canal and an extraction is decided by whether the tooth can be rebuilt and supported afterwards, not by which treatment sounds better. Where enough sound tooth remains above the gum and the root is healthy in solid bone, saving the tooth is usually the better long-term option. Where too little tooth is left, or a fracture runs below the bone, removing it is the honest answer — and paying more to keep a tooth that will not last is not a good outcome.

If you have been given both options and want the reasoning explained plainly, ask — you are entitled to understand it.

What is root canal treatment?

Inside every tooth is a soft core — the pulp — containing the nerve and blood supply. When bacteria reach it through deep decay, a crack or an injury, the pulp becomes inflamed and then dies. It does not recover on its own, and the infection eventually travels out of the root end into the surrounding bone.

Root canal treatment removes that pulp, cleans and shapes the canals inside the roots, and seals them. The tooth stays in place and continues to function. It has no living nerve inside it afterwards, which is why a treated tooth becomes more brittle and usually needs a crown to protect it from splitting.

What does an extraction involve?

The tooth is removed under local anaesthetic. A simple extraction is one where the tooth can be lifted out through the socket. A surgical extraction is needed where the tooth is broken at the gum line, heavily curved, or has to be sectioned to come out — the gum is lifted and the tooth removed in pieces.

Removal ends the problem definitively. It also leaves a gap, and what happens to that gap is part of the decision rather than a separate question.

How is the decision actually made?

These are the things being assessed, roughly in order of how much weight they carry.

How much sound tooth is left above the gum

This is usually the deciding factor. A crown needs a band of solid tooth structure to grip — a collar right around the tooth above the gum line. Where decay or fracture has taken the tooth down to or below the gum on one or more sides, there may be nothing for a crown to hold, and a rebuilt tooth would come apart under normal chewing.

A tooth with most of its walls intact is a straightforward candidate to save. A tooth broken to the gum on three sides usually is not.

Where the crack or fracture runs

A crack confined to the crown of the tooth can often be managed. A fracture running vertically down the root, or a break extending well below the bone level, generally cannot be sealed or restored, and the tooth is removed. This is assessed with X-rays and direct inspection, and is sometimes only confirmed once the old filling is removed.

The bone and gum support around the root

Root canal treatment fixes the inside of a tooth. It does nothing for the outside. Where periodontal disease has already taken much of the supporting bone and the tooth is mobile, treating the canals will not give a tooth that stays. In those cases the periodontal condition drives the decision.

Whether the canals can be cleaned and sealed

Some roots are heavily curved, calcified with age, or previously treated and blocked. Where the canal system cannot be adequately cleaned, the success of treatment drops, and that is factored in honestly rather than discovered afterwards.

Which tooth it is, and what it does

A front tooth carries appearance and speech as well as function. A first molar does a large share of the chewing. A third molar with an opposing tooth already missing may be doing very little work, and removing it may cost nothing in function — which changes the arithmetic considerably.

Your general health and your plans

Medical conditions, medications such as bone-modifying drugs, radiotherapy history, and how well the mouth is likely to be maintained all feed into the recommendation. So does what you want, and there is nothing wrong with saying you would rather not have a long course of treatment.

What do the options cost?

These are the figures at Berala Dental. Every one of them assumes your private health fund contributes nothing — in practice a fund may pay some, most, or in some cases all of an item, and a quote can be run against your specific policy. A written quote is provided before treatment begins.

• Root canal treatment: $1,600 to $2,200, depending on the tooth and the number of canals.
• Crown after root canal treatment: $1,500 to $1,800. Most back teeth need one; some front teeth do not.
• Simple extraction: $350 to $550.
• Surgical extraction: $650 to $850.
• Implant to replace the tooth: $4,500, or $5,000 where a bone graft is needed.

Set out plainly: saving a back tooth commonly lands somewhere around $3,100 to $4,000 all in. Removing it is $350 to $850. Removing it and replacing it with an implant is $4,850 to $5,850.

So extraction is the cheaper option on the day, and it is not necessarily the cheaper option over ten years — but that depends entirely on whether the gap needs filling. Which brings us to the part that is often skipped.

What happens to the gap?

Not every extracted tooth needs replacing. A rear molar with no opposing tooth is frequently left alone with no consequence at all, and saying so is part of an honest conversation.

Where a tooth in the working part of the bite is removed and not replaced, teeth either side can tilt into the space over time and the opposing tooth can drift down into it, which changes the bite. The options are an implant, a bridge, or a partial denture, and they are compared in implants versus bridges versus dentures. Berala Dental does not make dentures and refers prosthetic work out; implants are placed in-house.

The point is that the real comparison is not root canal against extraction. It is root canal and crown against extraction plus whatever the gap needs — which may be nothing.

Does Berala Dental do root canal treatment?

Yes. Berala Dental is a general dental practice and provides root canal treatment.

There is no endodontist on site. Endodontist is a protected title under the National Law, held only by practitioners with specialist registration through AHPRA after several additional years of full-time training. Endodontists handle the cases general practice should not: severely calcified canals, retreatment of failed root canals, internal or external resorption, and complex root anatomy. Where a tooth falls into that category, the practice refers rather than persists.

Is one more uncomfortable than the other?

Both are done under local anaesthetic. The pain people associate with root canal treatment is generally the pain of the infected tooth beforehand, and that usually settles once the pulp is removed.

Root canal treatment takes longer in the chair, often across two visits. An extraction is quicker on the day and has a recovery period afterwards, with the socket taking a few weeks to close over. Happy gas is available at $120 for anyone who finds dental treatment difficult.

Quick answers

Is it always better to save the tooth?

Not always, and this is worth being direct about. A natural tooth that can be properly restored and supported is generally the better long-term option. A tooth that cannot be restored, or sits in bone that no longer supports it, is not made better by expensive treatment. Keeping a tooth is a good goal, not an automatic one.

How long does a root canal treated tooth last?

Where the tooth is properly restored, usually with a crown, and the gums are kept healthy, many last for decades. Where it is left without adequate coverage, the most common failure is the tooth splitting under normal chewing, which then means extraction anyway. The restoration afterwards matters as much as the root canal itself.

Can antibiotics fix it instead?

No. Antibiotics can settle a spreading infection and are sometimes used alongside treatment, but they do not reach inside a dead tooth and they do not remove the cause. The infection returns once the course finishes. See the warning signs of a dental abscess.

What if I do nothing?

An infected tooth does not heal. It typically progresses to an abscess, and can flare into a spreading facial infection. Waiting also tends to remove the option of saving the tooth, because more structure is lost in the meantime.

Getting a straight answer on a tooth

A focused consultation on one specific problem is $80, with any X-rays clinically required included in that fee. A full treatment plan — examination, imaging and a written plan — is $120, or $150 with the principal dentist. Prices assume no health-fund contribution. General information on root canal treatment is published by healthdirect.
