Let’s break down what orthodontic elastics are, how they work, and how to use them safely and effectively.
What Are Orthodontic Elastics?
Orthodontic elastics, sometimes called rubber bands, are small, stretchy loops made of medical-grade latex or synthetic materials. They’re different from the tiny ligatures that hold wires onto brackets — these elastics attach to hooks on your braces or aligners to apply directional force.
That force helps move your teeth and jaw into the correct position, especially in cases where bite correction is needed. Whether you’re dealing with an overbite, underbite, or crossbite, elastics help fine-tune those shifts that braces or aligners alone may not fully correct.
Types of Orthodontic Elastics and Their Functions
Not all elastics serve the same purpose. Depending on your treatment plan, your orthodontist might prescribe different configurations based on your bite and goals. Here are a few common types:
- Class I elastics — Used within one arch to close gaps or adjust position
- Class II elastics — Connect the upper teeth to lower molars, often for overbites
- Class III elastics — Connect lower teeth to upper molars to help correct underbites
- Vertical elastics — Help align your upper and lower teeth vertically
- Cross elastics — Used to fix crossbites or correct midline discrepancies
Your orthodontist will show you exactly where to place your elastics based on your individual case. Following their instructions closely is essential for getting the right results.
How to Put On Orthodontic Elastics
It may take a little practice, but once you get the hang of it, applying elastics becomes part of your daily routine. Here’s a safe and effective way to do it:
- Wash your hands before handling the elastics.
- Use a mirror to help you see where to place them (at least at first).
- Hook one end of the elastic onto the prescribed bracket or aligner hook.
- Stretch the elastic and hook the other end to the opposite location as directed.
- Double-check placement to make sure it matches what your orthodontist showed you.
You might be given a small tool (like a hook) to help place them more easily. With time, most patients can do it quickly and without a mirror.
How Often Should You Wear Your Elastics?
Consistency is everything with orthodontic elastics. In most cases, you’ll be told to wear them:
- 20 to 22 hours per day
- At all times except while eating or brushing
- Replacing them at least once or twice daily
Elastics lose strength as they stretch throughout the day. That’s why changing them out regularly is essential for keeping consistent pressure on your teeth and jaws. If you forget to wear them or remove them for long periods, you may prolong your treatment or undo previous progress.
Common Mistakes to Avoid
Orthodontic elastics are simple to use, but some common mistakes can compromise your results. Here’s what to avoid:
- Doubling up on elastics unless directed — More isn’t better and can harm your teeth or roots.
- Skipping days — Inconsistent use delays progress and confuses your teeth.
- Using damaged or expired elastics — Old elastics lose strength and elasticity.
- Incorrect placement — Always follow the exact configuration your orthodontist recommends.
If you lose your supply or run out early, contact your orthodontist immediately. Don’t try to substitute them with rubber bands or other materials — it’s not safe and won’t give you the same results.
What to Expect When You First Start Wearing Elastics
When you first start wearing orthodontic elastics, it’s normal to feel some soreness. That pressure means the elastics are doing their job. Over-the-counter pain relievers can help, and most discomfort fades within a few days as your mouth adjusts.
If you continue to experience pain beyond the first week or if you notice any damage to your brackets or aligners, check in with your orthodontist. They may adjust your prescription or placement.
Tips for Success With Orthodontic Elastics
- Keep extra elastics with you — Store a few in your backpack, purse, or car.
- Set reminders — Especially at first, to help you stay consistent with wear time.
- Monitor progress — Small improvements over time help you stay motivated.
- Communicate with your orthodontist — If you’re unsure about anything, ask.
How Orthodontic Elastics Fit Into Aligners
Yes — elastics are used with clear aligners too! Many patients with Invisalign or similar systems will receive elastic hooks or cutouts on their trays for this purpose. Just like with braces, the elastics provide the additional force needed for certain movements that aligners alone can’t achieve.
