Rubber bands with braces, called elastics, connect a hook on an upper bracket to a hook on a lower bracket. They pull the jaws and teeth into a better bite, which brackets and wires cannot do on their own. Most patients wear them most of the day for part of treatment.
If your orthodontist has just handed you a little bag of tiny rubber bands, you probably have questions. Why do you need them now, when the braces seemed to be doing fine? How long do you wear them, and what happens if you forget? Below, we explain what elastics actually do, the common ways they are worn and the habits that keep treatment on schedule.
What Do Rubber Bands Do for Braces?
Brackets and an archwire are excellent at straightening teeth within each arch. They line teeth up, close spaces and rotate crooked teeth into place. What they cannot do by themselves is change how the upper teeth meet the lower teeth, because the upper and lower wires are not connected to each other.
That is where elastics come in. Our post on how braces work explains that elastics connect different brackets to help align the upper and lower teeth, and that the placement of the bands, combined with the steady force from the archwire, builds a balanced, functional bite. In plain terms, the wire straightens and the rubber bands fix the bite.
Elastics are one of the reasons braces can correct bite problems such as overbites, underbites and crossbites. Our braces page lists those bite issues among the problems braces fix for kids, teens and adults, and rubber bands are often the tool doing that work once the teeth are lined up.
Are These the Same as the Colored Bands on Braces?
No, and this trips up a lot of families. The colorful rubber bands that go around each bracket, the ones patients love to customize at each visit, hold the archwire in the bracket. They stay on all the time and only the orthodontic team changes them.
Bite elastics are different. They are small, removable loops that stretch between two hooks, usually from the upper jaw to the lower jaw. You put them on and take them off yourself, and you replace them with fresh ones every day. Clear ceramic braces can use bite elastics too, so the same instructions apply whichever style you chose.
| Colored bands (ligatures) | Bite elastics | |
|---|---|---|
| Where they go | Around each bracket | From a hook on one tooth to a hook on another |
| Job | Hold the wire in the bracket | Move the bite and jaws into position |
| Who changes them | The orthodontic team, at visits | You, several times a day |
| Removable at home | No | Yes, for eating and brushing |
| Used by | Most patients with metal braces | Patients whose plan includes bite correction |
What Are the Common Ways Elastics Are Worn?
The pattern depends on which bite problem is being corrected. Your orthodontist will show you exactly where yours go, often with a drawing or a photo to take home. The most common setups fall into a few groups.
Class II elastics run from an upper front hook, usually near the canine, back to a lower molar. They help correct an overbite where the upper teeth sit too far ahead of the lower teeth. Class III elastics run the opposite way, from a lower front hook back to an upper molar, to help with an underbite. Vertical or box elastics run up and down between upper and lower teeth to close an open bite or settle the teeth together, and crossbite elastics run across from the inside of an upper tooth to the outside of a lower one.
You do not need to memorize the names. What matters is following the pattern you were given, changing the bands when told, and asking at your next visit if anything is unclear. Many patients wear elastics for only part of treatment, often after the teeth are lined up and the wires are stiff enough to handle the pull.
How Do You Put Rubber Bands On?
It feels awkward the first few times and becomes automatic within a week or so. Wash your hands, then hook one end of the elastic onto the upper hook your orthodontist showed you. Stretch the band down to the lower hook and slip it on, keeping it flat rather than twisted. Use a mirror until you know the pattern by heart.
Some patients find it easier to use their fingernails, while others use a small plastic placer tool, which your orthodontic team can show you how to use. Many people put on the side that is harder to reach first. If a hook is hard to see, open wide, relax your cheek and tilt your head toward the light. Keep a bag of elastics in your backpack, purse or car so you can replace a band after lunch or a snack without going home.
How Many Hours a Day Should You Wear Rubber Bands?
Unless your orthodontist tells you otherwise, elastics are usually worn nearly all the time, including while you sleep. They come off to eat and to brush, then go right back on. The reason is simple: teeth respond to steady, continuous force. Wearing elastics for a few hours and then skipping a day lets the teeth drift back, so you lose ground and have to repeat it.
Fresh elastics also matter. Rubber bands lose their stretch as they are worn, so most patients are asked to replace them several times a day, including after meals. A worn-out band is barely pulling, even if it is still on your teeth. Our timeline post on how long braces take explains why steady wear is one of the biggest factors in keeping treatment on schedule.
Do Rubber Bands Hurt?
Expect some soreness for the first few days after you start elastics, or after switching to a stronger pattern. The pressure feels like the tenderness you had when your braces first went on, and it fades as your teeth adjust. The patients who struggle most are the ones who take the bands off when they feel sore, because each restart brings the soreness back.
Soft foods, over-the-counter pain relievers and a warm salt water rinse help the first few days, the same steps we suggest when braces first go on. Our first-week food guide has easy meal ideas. If a hook breaks or a bracket comes loose, you cannot wear the elastic correctly, so call or text the office. Our guide to broken brackets and poking wires covers what to do until you are seen.
Frequently Asked Questions
What happens if I forget to wear my rubber bands?
A missed hour here and there is not a disaster, but regularly skipping elastics slows the bite correction and can add time to treatment. Put them back on as soon as you remember.
Can I eat with rubber bands on?
Take them off to eat and brush, then put in fresh ones. Eating with elastics on stretches and weakens them and can pull them out of place.
What if a rubber band breaks?
Replace it with a new one right away. Carry a few spare bands with you to school or work so a snapped band never means hours without elastics.
How long will I need to wear elastics?
It depends on your bite. Some patients need them for a few months and others longer. Your orthodontist checks the bite at each visit and tells you when you can stop or change patterns.
