Orthodontic elastics, commonly called rubber bands, are used in brace treatment to apply specific, continuous forces. Unlike the wires and brackets that primarily straighten teeth, elastics correct the alignment of the upper and lower jaws to achieve a proper bite. They are designed to work synergistically with the brackets and wires to move groups of teeth or the entire dental arch into their prescribed positions. Because elastics lose their elasticity over time and must be worn consistently, patients require a reliable and ongoing supply throughout their treatment period.
Obtaining Elastics Directly From Your Orthodontist
The most reliable and recommended place to secure replacement elastics is directly from the prescribing orthodontic office. The orthodontist has precise records of the patient’s current treatment phase and the exact specifications required to ensure proper tooth movement. Using an incorrect band can potentially reverse progress or introduce undesirable forces. Patients can request a refill during scheduled adjustment appointments, or contact the office by phone if they run out between visits to arrange mailing or pickup.
In most cases, the cost of the necessary elastics is included within the comprehensive treatment fee, meaning patients usually receive refills without an additional charge. Since the office stocks only medically approved and verified brands, obtaining bands here eliminates the risk associated with unverified sources. This practice ensures continuity of care and adherence to the precise biomechanical plan established for the patient.
Understanding Your Elastics Prescription Details
Understanding the specific details of the elastic prescription is necessary for safe and effective treatment. Each package of orthodontic elastics is labeled with two specific metrics that define its function: the diameter and the force rating. The diameter, often measured in fractions of an inch (e.g., 1/8″, 1/4″), dictates how far the elastic must stretch between the attachment points. The force rating, measured in ounces (e.g., 3.5 oz, 6.0 oz), determines the amount of continuous pressure applied, and orthodontists select this specific combination to achieve a biomechanically sound movement rate.
Applying an elastic with the wrong specifications can have unintended consequences for treatment progress. For instance, an elastic that is too strong can cause excessive pressure, potentially damaging tooth roots or leading to pain. Patients should always verify the diameter and force rating against their current prescription package before considering alternative sources for replenishment.
Sourcing Elastics from Retail and Online Vendors
While the orthodontist’s office is the preferred source, patients sometimes seek alternative vendors for convenience or in an emergency. Online retailers, including large marketplaces and specialty dental supply websites, offer a wide variety of orthodontic elastics. The convenience of these platforms allows patients to quickly replenish their supply without needing an office visit or waiting for postage. However, purchasing elastics online carries an inherent risk regarding product authenticity and quality control.
Bands sold by unverified third-party sellers may be counterfeit or made from substandard latex or synthetic rubber, potentially breaking easily or failing to deliver the specified force. Inaccurate force delivery can slow or even reverse the intended movement, disrupting the biomechanical plan, so patients should look for reputable manufacturers to ensure quality assurance.
Physical retail locations, such as drug stores and pharmacies, occasionally stock common sizes of orthodontic elastics, but availability is often sporadic. Any purchase made outside of the prescribing office must precisely match the diameter and force ratings found on the patient’s current prescription packaging. Patients should always be cautious when using these alternative sources and should contact their orthodontist before relying solely on them for their ongoing supply.
