In this blog, we’ll break down everything you need to know about dental retainers, from the different types available, how much they cost in Australia, to how to care for them properly. It might not sound super exciting, but trust us, it’s better than having your teeth shift back to square one!
So, you’ve finally finished your braces or Invisalign treatment—congrats! After months (or even years) of straightening your teeth, your smile’s looking pretty spot on. But before you go celebrating too soon, there’s one final step to lock in that smile for good: wearing a dental retainer.
What’s a Dental Retainer Anyway?
A dental retainer is a custom-made appliance that helps keep your teeth in their new, aligned position after you’ve had orthodontic treatment. Your teeth are constantly under pressure from things like chewing, speaking, and even just sleeping. Without a retainer, they can slowly drift back to where they started, and no one wants to waste all that time and money.
Think of retainers as your teeth’s security guard—keeping everything in line and making sure your hard-earned smile stays put.
Types of Dental Retainers
There are a few different kinds of retainers, and the best type for you depends on your lifestyle, personal preference, and what your orthodontist recommends. Let’s go through the main ones:
1. Hawley Retainers (Removable Wire Retainers)
These are the classic retainers you’ve probably seen before. Made with a combination of metal wires and acrylic, they fit snugly over your teeth and are adjustable.
Pros:
- Durable and long-lasting
- Can be adjusted if your teeth move slightly
- Easy to clean
Cons:
- Visible metal wire when you smile
- Can affect speech when you first wear it
- Some people find it a bit bulky
2. Clear Plastic Retainers (Essix or Vivera Retainers)
These are clear, removable retainers that look a bit like Invisalign aligners. They fit tightly over your teeth and are nearly invisible.
Pros:
- Discreet—no one will notice you’re wearing it
- Comfortable and lightweight
- Easy to pop in and out
Cons:
- Not as durable as Hawley retainers
- Can warp with heat (so don’t leave them in a hot car!)
- May need to be replaced more often
3. Permanent (Fixed) Retainers
These are thin wires that are glued to the back of your front teeth, usually on the lower jaw. You can’t take them out—they’re in there 24/7.
Pros:
- You don’t have to remember to wear them
- Always working to keep your teeth aligned
- Invisible from the front
Cons:
- Can make flossing tricky
- Needs regular check-ups to make sure the wire stays intact
- May cause plaque buildup if not cleaned properly
How Much Do Retainers Cost in Australia?
Here in Australia, the cost of a dental retainer can vary depending on the type and where you’re getting it done. Here’s a rough guide:
| Type of Retainer | Average Cost (AUD) |
| Hawley Retainer | $150 – $300 per arch |
| Clear Retainer | $200 – $400 per arch |
| Permanent Retainer | $250 – $500 per arch |
If you lose or break your retainer, you’ll need to pay for a replacement, which is usually the same price. Some orthodontic clinics offer a package that includes a set of replacement retainers, so it’s worth asking about that when you finish your braces.
Also, check if your private health insurance covers orthodontics—some policies will chip in for the cost of retainers.
How Long Do You Have to Wear a Retainer?
The truth is… probably forever. But before you freak out, hear us out.
Right after your braces come off, you’ll likely need to wear your retainer full-time for a few months. After that, you can usually switch to just wearing it at night. The longer you wear your retainer, the better your chances of keeping your teeth straight for life.
Some people wear their retainers a few nights a week even years after treatment—and their smiles still look perfect.
Tips for Retainer Care
Whether your retainer is removable or fixed, taking care of it properly will keep it clean, functional, and odour-free.
For Removable Retainers:
- Clean it daily: Rinse it under cold water after removing it and brush it gently with a soft toothbrush (no toothpaste—it’s too abrasive).
- Deep clean weekly: Use a denture or retainer cleaning tablet once a week to give it a proper clean.
- Keep it in a case: Always store it in a protective case when not in use. Don’t just wrap it in a tissue—it’ll end up in the bin!
- Avoid heat: Don’t leave it near heaters or in hot water—it can warp easily.
For Fixed Retainers:
- Floss carefully: Use floss threaders or special interdental brushes to clean between your teeth and under the wire.
- Regular dental check-ups: Let your dentist or orthodontist check it regularly to make sure it’s still properly bonded.
- Watch what you eat: Avoid biting into hard foods (like apples or crusty bread) with your front teeth to avoid damaging the wire.
What Happens If You Don’t Wear Your Retainer?
We hate to break it to you, but if you skip wearing your retainer, your teeth will move. Sometimes it happens slowly, and sometimes it’s noticeable within weeks. Your teeth have a sneaky way of shifting back to their old positions, especially in the first year after treatment.
If it’s been a while since you wore your retainer and it no longer fits, don’t try to force it. Go back to your orthodontist—they might suggest a new retainer or a short treatment plan to get things back in shape.
Final Thoughts
Retainers might not be the most glamorous part of orthodontic treatment, but they’re absolutely essential for maintaining your results. Whether you go for a clear plastic retainer, a trusty Hawley, or a fixed wire, the key is consistency and care.
It’s a small commitment for a lifetime of confident smiles. So chuck it in your routine, look after it properly, and your smile will thank you for years to come.
