Rubber bands for braces play a critical role in correcting bite issues, aligning the jaw, and ensuring optimal results that braces alone can’t achieve. Whether you're dealing with an overbite, underbite, or spacing concerns, these elastics provide the precise pressure needed for a balanced, confident smile. Book a consultation with Leaside Orthodontic Centre to learn how rubber bands can accelerate your orthodontic journey.
What Are Rubber Bands for Braces
Rubber bands for braces, or orthodontic elastics, are small, stretchy loops made from medical-grade latex or latex-free synthetic materials designed specifically for orthodontic use. These bands are not the same as the colorful ligatures you see wrapped around brackets — those are mostly for aesthetics and holding the wire in place.
Instead, rubber bands provide extra force to help guide the movement of teeth and jaws in directions that braces alone cannot achieve.
They come in
Various sizes (small, medium, large)
Different strength levels (light, medium, heavy)
Multiple configurations depending on the treatment needs
Did You KnowOrthodontic rubber bands are engineered for precise tension and elasticity, making them safe and effective for daily wear.
Why Are Rubber Bands Used in Orthodontic Treatment
Orthodontists prescribe rubber bands to fine-tune the alignment of your bite and jaws. Here's how they help
Primary Functions
Bite Correction
Rubber bands are often used to correct malocclusions (bite problems) including
Overbite – when the upper teeth overlap the lower teeth too much
Underbite – when the lower teeth extend past the upper teeth
Crossbite – when upper and lower teeth don't align properly
Open bite – when the front teeth don't touch when the mouth is closed
Teeth Alignment
They can assist in moving groups of teeth or even entire arches, especially when significant alignment is needed
Closing Gaps
Elastics apply consistent force to close spaces between teeth or ensure proper spacing throughout treatment
Jaw Positioning
By connecting the upper and lower teeth, elastics help adjust the jaw into proper alignment leading to a more balanced facial profile
Additional Benefits
Help speed up treatment with constant and controlled pressure
Allow for targeted movements braces can’t handle alone
Types of Rubber Bands for Braces
Rubber bands are categorized by purpose, size, and force level
Classification by Purpose

Class I | Same arch (upper or lower) | Minor tooth adjustments |
Class II | Upper front to lower back | Correct overbites |
Class III | Lower front to upper back | Correct underbites |
Vertical | Top to bottom (same side) | Maintain upright tooth positioning |
Cross | Diagonally across mouth | Correct crossbites and midline shifts |
Classification by Size and Force
Size | Force Level | When Used |
Small | Light | Minor corrections or sensitive areas |
Medium | Medium | General bite correction |
Large | Heavy | Severe misalignments or jaw shifts |
Pro Tip

How Do Rubber Bands Work

Depending on your treatment, the bands might be worn in various configurations
Triangular
Box-shaped
Figure-eight
Cross
