Short answer: The animal names on braces rubber bands are a code that makes it easier to remember the band's inner diameter and the force it applies. This coding is not standardized; each manufacturer uses its own system, and the same animal name can correspond to a different size from one company to another. For this reason, which elastic to wear, how often and where should always be determined by your orthodontist's instructions.
If your dentist handed you a small pack of rubber bands during braces treatment and said, "Change these a few times a day," you may have seen an animal name such as rabbit, fox, elephant or penguin on the pack. This is exactly one of the most commonly asked questions online: what do the animal meanings of braces rubber bands refer to? In short, the animal name is a code that makes it easier to remember the band's diameter and the force it applies. However, this code varies from manufacturer to manufacturer; so thinking that an animal name describes the same size for everyone can be misleading. In this article, we explain what braces rubber bands are for, the logic behind the animal names and how you should use the elastics in daily life.
Why are braces rubber bands called by animal names?
Braces rubber bands are called by animal names because they are made in dozens of very similar diameter and force options; the name lets both the dentist and the patient recognize the pack quickly. Orthodontic elastics are technically defined by their inner diameter in inches and their force in ounces or grams. An expression like "3/16 inch, medium force" is useful in the clinic, but it is hard for a child or teenager to remember.
For this reason, manufacturers have given each size-and-force combination an animal name and, often, a small drawing on the pack. When a patient says, "my rabbit pack has run out," the dentist and assistant can easily tell which elastic is meant in that company's system. In other words, the animal name is not decoration but a practical labeling method meant to reduce confusion.
Braces rubber bands and animal meanings: what does the animal name show?
The animal name basically shows two pieces of information together: the band's inner diameter and the force it applies when stretched. Orthodontic elastic sizes are usually expressed with values like 1/8, 3/16, 1/4 and 5/16 inch; force is divided into classes such as light, medium and heavy. A small-diameter elastic creates a noticeable pull when stretched over a short distance, while a larger-diameter elastic may be suitable for closing a longer distance in a more controlled way.
The most important thing to know here is this: animal names are not standardized. Each manufacturer uses its own coding. An elastic called "fox" at one company may refer to a certain diameter and force, while at another company the same name may correspond to a completely different size or may not be used at all. For this reason, charts circulating online in the style of "this animal means this" give a general idea but are not a reliable source for identifying the elastic in your own pack.
If you want to learn the properties of your own elastics, the right way is to look at the technical information on the back of the pack (the diameter and force statement) or to ask your dentist directly. The choice of elastic is made according to many factors, such as the position of the teeth, the bite relationship, the wire and bracket system used and the stage of treatment you are in. Even within the same treatment, you may be asked to switch to a pack with a different animal name over time.
What is the difference between colored ligatures and inter-arch elastics?
Colored ligatures are small rings that secure the wire to the brackets; inter-arch elastics are bands that apply force between the two jaws or between teeth and that the patient puts on and takes off themselves. These two groups are often confused, yet their roles are completely different.
- Ligature (colored ring): It is placed around each bracket by the dentist and holds the wire in its slot. It is generally renewed at check-up appointments. The color choice is an aesthetic preference; for details, you can look at our page on braces colors.
- Inter-arch elastic: It is attached to hooks on the brackets or to special buttons. It can help position the upper and lower jaws relative to each other, close an open bite or correct the midline. Animal names are used for the elastics in this group.
For more comprehensive information on the types and purposes of inter-arch elastics, you can read our article on orthodontic rubber bands and elastics. In clear aligner treatment, too, similar elastics can be used by attaching them to cut-outs in the aligner or to small buttons bonded to the tooth.
What is a braces rubber band for?
A braces rubber band adds a force in a direction and magnitude that the wires alone cannot provide, helping the jaws and teeth come into the right position relative to each other. The wire is effective at aligning the teeth within their own row; however, to regulate the relationship between the upper and lower jaws, an additional force is often needed.
The way the elastics are attached also varies according to the purpose. Some form a diagonal line from the upper canine to the lower molar, some are attached vertically in the front teeth area, and some connect more than one hook in a triangle or box shape. Which pattern suits you is determined during the exam and treatment planning. If you would like information about the general treatment process, our page on braces treatment can be a good place to start.
How are the elastics attached, and how often are they changed?
Elastics are attached between the hooks your dentist showed you, with a finger or a small tool provided, and in most cases they are replaced with a new one several times a day. Practicing in front of a mirror in the first days makes things easier; within a few days, this becomes a habit for most people.
These are the points to generally pay attention to:
- Wear time: Elastics are generally planned to stay in for most of the day, including at night. If your dentist recommended night-only use, follow that instruction.
- Change frequency: An elastic loses its flexibility over time and its force decreases. For this reason, most dentists ask for the elastics to be renewed after meals or several times a day.
- Eating and brushing: Whether the elastics are taken out while eating and brushing depends on your dentist's instructions. If they are taken out, a new elastic should be put in once you finish.
- Consistency: Wearing them one day and not the next can cause the teeth to move back and forth and can slow progress. Consistency is one of the main factors that determine the effect of the elastic.
A mild aching or feeling of pressure in the teeth in the first few days is common and shows that the teeth are getting used to the force. This feeling generally eases in a short time; if it does not go away or increases, you should let your dentist know.
What happens if the wrong elastic is used?
An elastic of the wrong size, the wrong force or attached in the wrong place may not produce the planned movement and can sometimes lead to unwanted tooth movement. For this reason, the choice of elastic and the way it is attached must be exactly as determined by your dentist.
For example, using an elastic with a heavier force does not speed up treatment; on the contrary, it can create unnecessary load on the teeth and supporting tissues and increase discomfort. A lighter elastic may not show the expected effect. Using a pack of elastics that a friend or relative uses because it is "the same animal" is also unwise, because, as we explained above, the same name can correspond to a different size from different manufacturers.
In addition, stacking two elastics on top of each other in cases the dentist did not recommend, or using an elastic for longer than recommended without changing it, is not right either. The magnitude and direction of the force are part of the treatment plan; changes that seem small can affect the result.
What should you do when an elastic breaks or runs out?
When an elastic breaks, it is enough to take a new one from the pack and attach it the same way; when the pack runs out, you need to ask your clinic for a new pack without waiting for the next appointment. Elastic breakage is quite common and is generally not a sign of a problem.
- Always carrying a few spare elastics with you prevents you from being left without elastics at school, at work or while traveling.
- Calling the clinic in advance when the pack starts running low reduces the risk of going without elastics for a few days.
- If the hook the elastic attaches to has broken, the bracket has come off or a wire is poking into your cheek, do not force the elastic on and let the clinic know.
We covered in detail what can be done in cases such as a wire poking or a bracket coming off in our article on emergencies such as a broken brace or a poking wire. If you would like to get to know the treatment process better, our article on metal braces may also help.

Frequently asked questions
Are the animal names on braces rubber bands the same in every brand?
No. Animal names are each manufacturer's own coding. An animal name at one company can correspond to a different diameter and force at another company. You can learn the properties of your own elastics from the technical information on the back of the pack or from your dentist.
How many times a day should braces elastics be changed?
Because elastics lose their flexibility over time, they are in most cases asked to be renewed several times a day, for example after meals. The exact frequency varies according to your treatment plan and is determined by your dentist.
Will treatment speed up if I wear a stronger elastic?
No. An elastic heavier than recommended does not speed up treatment and can create unnecessary load and discomfort on the teeth. The elastic should be used at the size and force determined by the dentist.
Are colored elastics and inter-arch elastics the same thing?
No. Colored elastics (ligatures) secure the wire to the brackets and are changed by the dentist at check-ups. Inter-arch elastics apply force between the two jaws or between teeth and are put on and changed daily by the patient.
What should I do if my elastic pack runs out?
It is recommended to call your clinic and ask for a new pack without waiting for the next appointment. Even going a few days without elastics can slow the progress of treatment.
