Braces elastics: what those rubber bands are for
Braces elastics (rubber bands) are a key part of orthodontic treatment that work with your brackets and wires to correct your bite and tooth position. Wearing them consistently as directed by your orthodontist is essential for treatment success.

How Elastics Work
Braces elastics — those small rubber bands you see on braces — do far more than add color. They apply gentle, steady pressure to move your jaw and correct your bite, working alongside your brackets and wires. While the brackets guide the up-and-down movement of individual teeth, elastics pull your upper and lower teeth into the right relationship. This coordination is why your orthodontist’s instructions about wearing and positioning them matter so much.
Wearing Your Elastics as Directed
Your orthodontist will show you exactly where to hook each elastic and how to position them — whether vertically, horizontally, or diagonally. Wear them exactly as shown, even if it feels awkward at first. The more consistently you wear them, the faster and more predictable your results.
Remove elastics only to eat and brush your teeth, then replace them immediately. Many patients find it helpful to carry a small pack with them so they can replace elastics right after meals. The goal is 20–22 hours per day of wear for most bite corrections; your orthodontist will confirm the right schedule for your case.
If an elastic breaks during the day, replace it as soon as you can. If you notice one is missing and don’t catch it for hours, don’t worry — just put on a fresh one. Consistency over perfection matters more than a single missed hour.
What to Do When You Run Out
Your orthodontist provides elastics at each visit, and the supply is meant to last until your next appointment. If you run out early — because you’ve lost some, they’ve worn out, or you simply miscounted — contact your orthodontist’s office immediately. Many practices can mail you extras or have replacement packs available for pickup. Some offices also teach patients how to contact them between visits for supplies.
Never try to reuse old, stretched elastics or make your own. Elastics are manufactured to precise specifications, and using worn-out or improvised ones can slow your treatment or cause problems.
Important: Don’t DIY Your Braces Mechanics
If an elastic feels like it’s in the wrong spot, pulling too hard, or just doesn’t seem right, don’t adjust it yourself. Contact your orthodontist. The same goes for any bracket that feels loose, a wire that’s poking, or any other issue with your braces. (See our guides on what to do if a bracket breaks and wire poking your cheek for urgent situations.)
Orthodontic treatment relies on precise pressure applied in the right direction and at the right intensity. Even a small misplacement of an elastic can affect how your bite develops.
Eating and Cleaning with Elastics
Remove your elastics before eating — they can get stained, damaged, or tangled on food. Hard, sticky, or crunchy foods can also damage your elastics and braces. For details, see our guide on what to eat with braces.
After eating, rinse your mouth and brush your teeth before replacing elastics. Food trapped under elastics can lead to plaque buildup and decay.

Frequently asked questions
Why do I need elastics if I already have braces?
Elastics work with your brackets and wires to correct your bite — how your upper and lower teeth meet. The brackets move your teeth vertically; elastics add the pull needed to align your bite, which is just as important as straight teeth.
What should I do if I run out of elastics before my next appointment?
Contact your orthodontist's office right away. They can often mail or email you replacements, or advise you to pick up a new pack. Don't try to stretch old elastics or go without; consistent wear is key to staying on schedule.
Can I adjust my elastics myself or use different ones?
No. Only your orthodontist should place or change elastics. Using the wrong size, thickness, or placement can damage your teeth or derail your treatment. If an elastic breaks or feels wrong, contact your orthodontist before the next visit.
