If you damage a tooth in an accident here in New Zealand, ACC will often help with the cost of putting it right. It's one of the better parts of our system, and a lot of people don't realise they're covered until we tell them. Here's how it works, in plain terms.
What ACC is, and why teeth are included
ACC is the Accident Compensation Corporation. It's a no-fault scheme, which means it doesn't matter whose fault the accident was. If an injury happened by accident, ACC may help cover the treatment. That cover extends to your teeth and jaw, not just broken arms and sprained ankles.
The key word is accident. ACC covers sudden injuries caused by something external: a knock, a fall, a collision, a bite onto something you didn't expect to be hard. It does not cover the slow, everyday things that happen to teeth over years. That distinction is what most questions come down to, so it's worth getting clear on.
What counts as an accidental dental injury
Most accidental tooth injuries we see fall into a few familiar patterns. A ball or an elbow to the mouth during sport. A trip on the stairs or a fall off a bike. A car or workplace accident. And, more often than you'd think, biting down on something hard that was hiding in your food, like a stone in a bag of nuts or an olive pip.
In each of those cases something external and unexpected caused the damage in one moment. That's the test ACC applies. The injury might be a tooth knocked out, a tooth broken or chipped, a crown or filling smashed, a tooth pushed loose or out of line, or a cut to the lips and gums that came with it.
- 1/A knock to the mouth playing rugby, netball, football or hockey
- 2/A fall at home, on the footpath, or off a bike or scooter
- 3/Biting unexpectedly onto a stone, pip or bone hidden in food
- 4/A car crash or a workplace accident that involved the face
Where ACC stops: wear, decay and grinding
ACC covers injuries, not conditions that build up over time. So it doesn't cover tooth decay, gum disease, or the general wear that comes from years of chewing. If a tooth breaks while you're eating normal food and there was nothing hard or foreign in it, that's usually treated as wear rather than an accident, and ACC won't cover it.
Grinding and clenching sit in the same bucket. The damage they cause happens gradually, so it isn't an accident in ACC's eyes. There's a grey area too: a tooth already weakened by a large filling or old decay might break more easily in a minor knock, and ACC will look at how much of the damage was the accident and how much was the pre-existing state of the tooth. We're honest with you about which side of that line we think a case sits, and ACC makes the final call.
We lodge the claim with you
You don't need to sort out ACC before you come in, and you don't need to fill in forms at home. We're a registered ACC provider, so we lodge the claim with you at the visit. We examine the tooth, take any X-rays we need, note down how the injury happened, and submit the claim electronically. Most of the time you'll have an answer quickly.
It helps if you can tell us clearly what happened and roughly when. If it was recent, that's straightforward. Claims can usually still be lodged for older injuries, but the sooner the better, both for the paperwork and for the tooth. If you're not sure whether something is covered, ring us and ask. Working that out is part of our job, not yours.
Surcharges: what you might still pay
It's important to be upfront: ACC cover usually isn't the whole bill. ACC pays a set contribution towards dental treatment, and that contribution often sits below the full cost of the work. The difference is called a surcharge or a gap, and it's the part you pay.
How big that gap is depends entirely on what the tooth needs, from a simple bond-up of a chip through to a crown or, in a bad break, root canal treatment. Before we start anything beyond first aid, you'll get a written quote that shows what ACC is expected to contribute and what your share looks like, so there are no surprises. If you're airport staff, the 15% airport discount can apply to your portion as well.
If a tooth is knocked out right now
A tooth that's been knocked completely out is the one dental injury where minutes genuinely count, so act before you think about paperwork. Pick the tooth up by the crown, the white part you chew with, and avoid touching the root. If it's dirty, rinse it briefly in milk rather than scrubbing it.
If you can, gently push an adult tooth back into its socket and bite on a clean cloth to hold it there. If you can't, keep it in a cup of milk or tucked inside the cheek, and get to us fast, ideally inside the hour. Ring us on 09 964 0508 while you're on your way. Do not try to re-implant a child's baby tooth, as that can harm the adult tooth forming underneath. Whatever the injury, the ACC side gets handled once you're here.
Quick questions
- Do I have to pay anything if ACC covers my injury?
- Usually yes, a surcharge. ACC pays a set contribution towards the treatment, and the gap between that and the full cost is your share. We show it clearly in a written quote before we start.
- I chipped a tooth biting a stone in my muesli. Is that an accident?
- Very likely, yes. Biting unexpectedly onto something hard or foreign in food is treated as an accident. Bring it in, tell us what happened, and we'll lodge the claim with you.
- My tooth broke while eating normal food. Will ACC cover it?
- Often not, if there was nothing hard or foreign involved. That tends to be treated as wear or a pre-existing weakness rather than an accident. We'll give you our honest read, and ACC makes the final decision.
- How long do I have to make a claim?
- Sooner is better, both for the paperwork and for the tooth, but claims can usually still be lodged for older injuries. If you're unsure, ring us on 09 964 0508 and we'll talk it through.
