A Comprehensive Guide to Choosing the Right Dental Health Insurance for Your Family

Dental insurance seems straightforward. You pay a premium and in return, the insurance helps cover the cost of dental care. Yet, as with all types of insurance, the details can be more complicated: Most people have a general sense of what their medical insurance does and does not cover, but far fewer understand their dental benefits. Dental insurance plans often have a low annual maximum, high deductibles, lots of exclusions for expensive treatments, and waiting periods before they’ll cover work more involved than a cleaning. For many cost-conscious patients, dental insurance is useless for anything other than preventive care.

What public healthcare does and doesn’t cover

Public healthcare systems often do not fund the kind of everyday, out-of-hospital dental care that adults need. Some children get access to basic government-funded programs – the Child Dental Benefits Schedule (CDBS) in Australia gives eligible children a capped amount to spend on services like check-ups, x-rays, and fillings. But once those children age out of the program, and for all the other adults in the house, private dental insurance becomes the only practical barrier between your wallet and dental bills.

That insurance gap matters. About 38% of Australians aged 15 and over avoided or delayed a visit to the dentist due to cost. (That’s an Australian Institute of Health and Welfare stat, not just something we made up, we promise!) That figure is alarming, but what it highlights even more is that skipping the dentist is something many people are prepared to do. If you don’t structure your finances in a way that makes dental manageable, it quickly isn’t.

When it comes to whether your family ‘can afford’ the expense of private dental insurance, the question isn’t one of ‘can we or can’t we afford the premium?’ It’s about ‘how much are we planning to spend on dental each year, are you sure your insurer’s policy structure will result in your lowest annual total (including premiums and out-of-pocket), and is this the right structure for you?’.

General vs. major dental: they’re not the same category

Each dental insurance policy will separate your coverage into a minimum of two, usually three, tiers. These will be called something like general dental and major dental. However, what you need to do is look at what is in each category and the fine print rules that apply.

General dental – the sort of stuff we all should get done fairly routinely. Check-ups, scale and cleans, x-rays, basic fillings, fissure sealants. These are frequent, lower-cost services that most families use at least once or twice a year per person, meaning you will often be more likely to dent your annual limit here than on major dental.

Major dental – the type of non-elective and frequently more complex, often very expensive treatment you end up needing rather than wanting. Crowns, bridges, root canal therapy, endodontic surgery, dentures, surgical wisdom tooth extractions. These are less predictable but significantly more costly when they hit. A single crown (and at least one consultation plus often the root canal to go with it in reality) might cost you $1,500 to $2,500 depending on the material and where you live.

The fine print will often specify that some simpler surgery type things are classified as general dental (removal of wisdom teeth when not impacted plus relaxed/extracted and simple direct stitch surgery for the gum), and some things are neither fish nor fowl and don’t go to either (relatively simple emergencies, say a single chip or minor break in an otherwise healthy tooth that can be simply fixed with composite resin as long as there is no pulp exposure – this was my one emergency dental issue before moving to insurance that was rebated under general).

The other fine print is whether there are distancing rules in place where you can’t use your annual maximum for specific items (achievable, but expensive and non-essential things like bleaching sometimes) if you spend some already on something else or if one type doesn’t count towards the annual maximum they will pay out.

Building your extras policy around your actual dental needs

Most of the time, dental doesn’t come as a stand-alone insurance item. It’s part of an “extras” bundle that includes optical, physiotherapy, chiropractic, and the rest. That creates a decision: do you take a broader extras package that includes dental, or do you go for a dental-heavy policy that may have less generous benefits for everything else?

The right answer depends entirely on how much of the non-dental extras your family actually uses. If nobody in your family wears glasses and you rarely see a physio, then paying higher premiums for optical and physio coverage to get a slightly more generous dental sub-limit is a waste of money. Do the math on what your family spends across all extras categories in most typical years, then compare total out-of-pocket costs – that’s premiums plus what you pay because of benefit gaps – across two or three options.

Choosing a dental cover plan structure built around your actual needs is the only solid way to navigate the trade-off between paying more than you need to for unused coverage versus regretting that you went cheap when major costs hit. This is true of all health insurance, but the less most of us tend to think about extras until we’re sitting in the dentist’s chair or waiting for our new reading glasses, the more prone we are to underinsure.

How waiting periods actually work

Many people don’t understand how waiting periods on health insurance work, especially because they didn’t have to worry about these things the last time they were covered by Mum and Dad’s policy.

Here is how they work. After you join a new health policy, you won’t be able to claim straight away. Health insurance waits until you’ve been with them long enough for it to be “worth it” for them to have you as a customer. This period (usually two months) is your waiting period.

Insurers won’t pay any hospital benefits at all during this time, even for accidents or emergencies. They’ll only pay for hospital treatment after the waiting period for that treatment has expired.

If it’s easier to understand – waiting periods are like the excess you pay on your car insurance, but you spread it out over the year or two before you can use your cover.

This also helps to prevent people from joining a cover only when they know they will need expensive treatment soon.

Waiting periods were another reason I wanted to get my health insurance sorted early this year. It didn’t make sense to pay for something that I wouldn’t be able to claim on for six months or more.

Annual limits, sub-limits, and why the headline number can mislead you

A policy that has a $2,000 annual dental cap sounds pretty good. Except when you realize it is often a lot more complicated than that.

For starters, that $2,000 cap may not apply to everything covered under your policy. Policies often have sub-limits. The $2,000 may cover all dental costs, but it could be split between general and major dental expenses, and possibly orthodontics on top of that.

For example, general dental might be capped at $500 per year, the crown you need might be classified as major dental and have a sub-limit of $1,000 within the total, and orthodontics might have its own limit outside of that to cover your child’s braces.

Suddenly even though you have $1,500 remaining under your overall dental cap, your major dental cap is maxed out and you’ll be paying full freight for the crown. It’s a common trap to fall into.

When it gets complicated is when you are looking at a family policy. The cap might be the same, but is the major dental sub-limit per person, or shared? If one person needs more dental work, can they access the unused portion of their partner’s sub-limit? For some families, this can create real financial stress.

Orthodontic coverage is also a sore point for many families. It often isn’t subject to an annual sub-limit. It has a lifetime limit instead, which can be even more confusing.

Percentage rebates vs. set benefits: which model saves you more

One of the most practically useful distinctions in dental insurance is this. It’s also one no product disclosure really explains. Some policies pay you a percentage of your actual bill – 60 per cent back on any general dental service, for example. Others pay you a fixed dollar amount per service code – $85 for a scale and clean, regardless of what the dentist charges for it.

The first, percentage model, is usually more predictable and in my experience, over a year, performs best when your dentist charges above-average fees. If your scale and clean is $220 and the insurer pays you 60 per cent, you get $132 back and you’re $88 out of pocket. If a set-benefit policy pays you a fixed $85 for the scale and clean, your gap is $135. Of course, the percentage model also works to your advantage when your dentist charges below-average fees.

The set-benefit model can work better when your dentists charge somewhere close to the average the insurer calculates and spreads across the funds members. The way to properly evaluate this is to ring your fund using a current invoice from your dentist. Get them to read out what they pay for each code on that invoice. It’s in their schedule. Compare what they would pay under each model to the real bill and you’ll instantly know which type you own. It takes about 20 minutes and can save you easily a couple of hundred comfortably across a year.

Using the Child Dental Benefits Schedule alongside private insurance

If your kids qualify for children’s government dental benefits programs, don’t presume that your private insurance makes those benefits immaterial. The wiser strategy is using both, in the correct order.

Kids who qualify for children’s government dental benefits programs get a set dollar amount per year for basic dental work. Private insurance is usually a top-up or covers the gap over the government benefit. In a real sense, you can stretch both sources of coverage further – government benefits for the simple, easy, preventative work; private insurance for costs over the government cap or work the government program doesn’t cover.

The defining point for families is that parents, and older teenagers who have aged out of government programs, still need private coverage. The program may be ‘a children’s benefit program’, but adults also require coverage. Don’t find yourself underinsuring the grown-ups in the household just because the kids are covered.

A practical checklist for families reviewing or switching policies

Before you agree to a new policy or renew an existing one, run your family’s situation through these questions:

• What general and major dental work have we needed as a family for the past couple of years, and what are we likely to require for the next couple of years?
• Is it realistic that any of the kids will need orthodontics in the next five years? If so, will the waiting period be adequately covered by a current policy?
• What are the annual per-person limits for general dental, major dental, and orthodontics for each of the policies you’re evaluating?
• Do the policies operate on a percent-of-fee refund model, or a set benefits model, and which is more suitable for the typical range of fees charged by your actual dentist?
• Are there preferred provider networks, and can you access one?
• Finally, if you are considering switching, have you confirmed that your served waiting periods will carry over to the new level of cover?

None of that is particularly complex, but you truly do need to pull out the policy documents and go through the figures. The families who actually come out in front on dental insurance are the ones who do that homework before they sign, not after they’ve had a bad shock.

Dental costs are predictable enough in terms of the categories of treatment likely to come up in any family’s lifetime that, with the right level of cover for your circumstances, you should be able to absorb most of it. That’s the idea. The goal is not to get something for nothing, just to make sure you aren’t losing money.
