All About Orthodontic Elastics (Braces Bands)
If your orthodontist has just handed you a little bag of rubber bands and told you to start wearing them, it’s normal to wonder what they actually do and whether they really make that much of a difference. At Orthodontics at Parramatta, we see this with patients often, and the ones who understand how elastics work are the ones who get the best results.

Your orthodontist will show you exactly how to wear them at your appointment.Invisalign revolutionised modern orthodontics with a near-invisible series of aligners that gradually adjust teeth. But with innovation comes investment, and Australians often wonder: How much is Invisalign?
Orthodontic elastics are small rubber bands that connect your upper and lower braces to help correct your bite.
They work alongside your braces but only do their job when worn consistently, usually 22 hours a day.
Missing elastic wear is one of the most common reasons treatment takes longer than expected.
What Do Rubber Bands Do on Braces?
Metal braces and ceramic braces are very good at straightening individual teeth, but they work within a single arch at a time. When the upper and lower jaws need to move relative to each other, that’s a different kind of force altogether, and that’s what orthodontic elastics are for.
Braces bands attach to small hooks on your upper and lower brackets and apply gentle, continuous pressure across the jaws. Over time, that pressure shifts the bite into the correct position. Depending on your case, elastics might be correcting an overbite, an underbite, or a crossbite.
When Do You Start Wearing Braces Rubber Bands?
Not everyone needs elastics, and those who do don’t usually start wearing them straight away. They’re typically introduced a few months into treatment, once the individual teeth have been straightened enough for the jaw correction phase to begin.
At our Parramatta clinic, treatment is mapped out from the start using our iTero 3D scanning system, so your orthodontist will already have a clear picture of your bite and when elastics are likely to be introduced.
How Do You Wear Braces Elastics Correctly?
Your orthodontist will give you a specific configuration for your case, but the general rules are the same for everyone:
- Wear them for around 22 hours a day, removing them only to eat and to brush and floss.
- Put a fresh pair in straight after eating, not an hour later.
- Change them at least once a day. Elastics lose their tension over time, so a fresh pair each morning keeps the force consistent.
- Wear them on both sides unless told otherwise, since wearing one side only can pull the jaw unevenly.
- Don’t double up. Two elastics don’t mean faster treatment – they can cause damage.
What Are Class II and Class III Elastics?
These are the two most common elastic configurations, and they work in opposite directions.
- Class II elastics run from the upper canine down to a hook on the lower molar. They’re used to correct an overbite, pulling the lower jaw forward relative to the upper.
- Class III elastics run the opposite way, from the lower canine up to a hook on the upper molar. They’re used to correct an underbite, where the lower jaw sits too far forward.
Some patients need a different configuration entirely. What matters is the specific setup your orthodontist prescribes, not the general category.
What Happens If You Don’t Wear Your Elastics?
Unlike braces, which are fixed and apply continuous force, elastics rely entirely on the patient wearing them consistently. If you skip them for a day or two, the teeth and jaw can begin shifting back, meaning treatment takes longer.
Patients who wear their elastics consistently and as prescribed generally finish treatment on schedule, and those who don’t often find themselves in braces for longer than originally planned.

FAQs
Usually, a few months into treatment, once the individual teeth have been aligned. Your orthodontist will introduce them when the time is right for your case.
Around 22 hours a day. They should only come out for eating and for brushing and flossing, then go straight back in.
The teeth and jaw can start to shift back, and treatment progress slows or reverses. Consistent wear is what makes elastics work. Missing the occasional hour is fine, but regularly skipping them will extend your treatment time.
At least once a day. Elastics lose their elasticity over time, so changing them daily keeps the force consistent.
There’s usually some soreness when you first start wearing them, similar to the tenderness after a braces adjustment. It settles within a few days as your mouth adjusts.
It’s best to contact your orthodontist for a resupply rather than buying generic ones, since elastics come in different sizes and strengths, and the wrong ones can cause problems. Your clinic can provide the right ones for your prescription.
