Not Every Cavity Needs Filling Today
Modern dentistry has moved a long way from drill-and-fill. Early decay in enamel can often be arrested and re-mineralised rather than cut out, and a tooth that gets its first filling at forty rather than twenty-five is a tooth that will probably still be there at eighty. We treat what needs treating and we monitor what can be monitored — and we tell you which is which.

Why Every Filling Shortens a Tooth's Life
There is a concept in dentistry called the restorative cycle, and once you understand it you will make better decisions about your own teeth for the rest of your life.
A tooth gets a small filling. Fifteen years later the margin leaks, so it is replaced with a slightly larger one, because you cannot make a replacement filling smaller. Fifteen years after that the tooth is now more filling than tooth, so it cracks under load and needs a crown. The crown requires the tooth to be cut down substantially, which sometimes irritates the nerve, which leads to root canal treatment. A root-treated, crowned tooth is brittle, and eventually it fractures below the gum and is extracted. Then you are considering an implant.
Every step in that chain is competent dentistry. Nothing went wrong. The point is that the cycle starts with the first filling, and each step is bigger, more expensive and less recoverable than the last. Which means the single highest-value decision in dentistry is whether to place that first filling at all — and that decision is far less clear-cut than most people assume.
Decay that is confined to enamel and not yet cavitated can frequently be stopped and partially reversed. Fluoride, better cleaning between those specific teeth, changing the frequency of sugar exposure, and in some cases a topical agent will halt it, and the follow-up x-ray in twelve months shows it has not progressed. That tooth stays intact. Fill it instead and you have started the clock. The genuine skill is telling the two situations apart, which requires good imaging, honest judgement and — most usefully — a comparison with what the same tooth looked like last time.
Minimal Intervention Across a Lifetime
The same principle applies differently at different ages.
Children
Fissure sealants close the deep grooves in new adult molars before decay can start — prevention that requires no drilling and no anaesthetic. Early enamel decay in children re-mineralises particularly well because their saliva is working hard and their diet is changeable.
- Sealants over fillings where possible
- Diet frequency, not just quantity
- High-fluoride support for high-risk children
Young adults
The years when most first fillings get placed, and therefore the years where restraint pays off most across a lifetime. A borderline shadow at twenty-two that gets monitored and never progresses is a tooth saved for sixty years.
- Monitor rather than treat where appropriate
- Compare against previous x-rays
- Treat the cause, not just the hole
Middle age
Existing fillings reach the end of their life. The question shifts from whether to fill to whether to replace or repair — a leaking corner of a large filling can sometimes be patched rather than the whole restoration cut out and remade.
- Repair over replacement where sound
- Crowns before teeth split, not after
- Grinding assessed as a cause
Older patients
Root surface decay from gum recession and dry mouth, where the highest-value interventions are often preventive rather than restorative — high-fluoride toothpaste, saliva management and more frequent cleans beat drilling a root surface.
- Medication review for dry mouth
- High-fluoride prescription toothpaste
- Shorter recall intervals
Where This Actually Changes What We Do
Three concrete examples of conservative treatment.
01Monitoring Early Decay
An enamel-only lesion gets photographed and x-rayed, you get a specific prevention plan aimed at that tooth, and we compare in twelve months. If it has not moved, we keep watching. If it has, we treat it, and we have lost nothing by waiting — enamel decay does not progress fast enough for a year of observation to cost you the tooth.
02Imaging That Enables Restraint
You cannot safely monitor what you cannot measure. Digital x-rays and intraoral photographs from the same angles year on year turn a subjective impression into a genuine comparison, which is what makes a decision to wait defensible rather than negligent.
03Additive Rather Than Subtractive Cosmetics
Composite bonding adds material to a tooth without removing enamel and is fully reversible. Porcelain veneers require permanent enamel reduction. For chips, small gaps and edge wear, bonding is often the better answer and it leaves every future option open.

Questions About Treatment Decisions
The questions patients tell us they wish they had known to ask.
- Another dentist told me I need five fillings. Are they wrong?
- Probably not wrong, but possibly reading the same images differently, which is genuinely common and not evidence of anybody acting badly. Borderline lesions are a judgement call, and dentists sit at different points on the intervene-early versus monitor spectrum. What makes the decision better is information: previous x-rays showing whether those specific spots have changed, and a clear statement for each one about whether it has broken through into dentine or is still confined to enamel. Bring the plan and the images and we will go through them with you tooth by tooth.
- Is it dangerous to wait and watch a cavity?
- Not if it is the right cavity and the watching is real. Enamel decay progresses slowly — typically years, not months — so a twelve-month review carries very little risk, and if it has advanced we treat it then having lost essentially nothing. What makes it dangerous is watching without actually reviewing: no follow-up x-ray, no comparison, no prevention plan, and the patient does not come back for three years. Monitoring is an active plan with a date attached, not a decision to ignore something.
- You mention the restorative cycle — does the filling material change it?
- Yes, and this is the main reason composite has largely replaced amalgam beyond appearance. Amalgam has no adhesion, so the cavity has to be cut into a shape that mechanically locks the filling in — which means removing sound tooth structure purely to retain the material. Composite bonds chemically to the tooth, so we only remove what is actually diseased. Over a lifetime of replacements that difference compounds: each cycle starts from a smaller cavity, so it takes longer to reach the point where the tooth needs a crown. Where a cavity is already very large, though, the honest answer is that neither material is right and the tooth needs an onlay or crown to hold it together.
- Should I have my old amalgam fillings replaced?
- Not if they are sound. Replacing a functioning amalgam filling means cutting out healthy tooth structure alongside it and starting the cycle again, for no clinical benefit. Australian and international health authorities do not recommend removing intact amalgam restorations on health grounds, and the removal process itself releases more mercury vapour than leaving them in place. Replace them when they leak, crack, or the tooth around them fails — or, if you dislike how they look, understand that you are accepting a clinical cost for a cosmetic gain and make that choice knowingly.
- How often do I actually need x-rays?
- It depends on your risk, and any practice applying the same interval to every patient is not thinking about it. Someone with active decay or a history of many fillings might need bitewings every twelve to eighteen months. Someone with a stable mouth, no fillings and good hygiene might reasonably go two or three years. The dose from modern digital dental x-rays is very low — a set of bitewings is a small fraction of the natural background radiation you receive in a year in Perth. The right question is not how often, but what specific question will this image answer.
- What is a crack line, and does it need treating?
- Almost every adult molar has visible craze lines in the enamel, and the overwhelming majority are harmless surface features that need nothing. What matters is a crack that goes deeper and moves under load — the classic sign is a sharp pain on releasing a bite rather than on biting down, often on something hard or unexpected. Those need attention, usually a crown or onlay to hold the tooth together, because a crack that propagates into the root means the tooth is lost. So: visible line with no symptoms, monitor it. Sharp pain on release, come in.
- Will you tell me if I do not need treatment?
- Yes, and it happens regularly. There is a reasonable amount of we would leave that alone in a well-run practice. If you have come specifically for a second opinion and we agree with the original plan, we will tell you that too — a second opinion that confirms the first is a useful result, not a wasted appointment.
- Can I have copies of my x-rays?
- Yes, at any time, and you do not need to give a reason. They are your health records and you have a right of access to them under Australian privacy law. If you want to take them to another practice for a second opinion, we will email them across. Any practice that makes this difficult when significant treatment is being proposed is telling you something worth listening to.
