Orthodontic rubber bands, also known as elastics, are small, stretchable loops that apply targeted force to the teeth and jaws. They are frequently used with braces to correct malocclusions, such as overbites, underbites, and crossbites. Elastics create constant tension, guiding the upper and lower dental arches into their planned positions. Since these bands are replaced multiple times daily, patients often need replacements when their supply runs out.
Retail Availability: The Short Answer
The definitive answer to whether you can purchase the correct orthodontic rubber bands at a retail store is generally no, especially for the prescription-grade elastics needed for bite correction. Orthodontic elastics are considered regulated medical devices, and their specific properties are determined by a dental professional. While a local pharmacy or big-box store may carry some non-specific dental supplies, such as dental wax or generic elastic bands, these are not the regulated interarch elastics your orthodontist prescribes. Relying on such generic products is not advised because they lack the specific calibration required for safe and effective tooth movement.
The Importance of Professional Prescription and Sizing
Orthodontic elastics are not standardized; they are highly customized tools selected to achieve a specific biomechanical outcome. The bands are prescribed based on three factors: diameter, force, and material. Diameter determines how far the band must stretch between two anchor points on the braces. The force is a measure of tension, calibrated in ounces or grams, ranging from light to heavy. This specific force calibration is designed to stimulate the biological process of bone remodeling around the tooth roots without causing damage. Using a band with the wrong force or size can move teeth incorrectly, which may prolong treatment or even require corrective measures.
Risks Associated with Non-Orthodontic Bands
Using non-orthodontic bands, such as craft elastics or generic rubber bands, poses significant risks to dental health and treatment progress. These products are made from materials that are not medical-grade and can break down in the mouth, potentially releasing non-sterile or toxic components. More damaging is the application of uncontrolled force, as generic elastics lack the calibrated tension needed for safe tooth movement. Excessive, unregulated force can cause serious complications, including root resorption, where the tooth root dissolves back into the body. Unplanned movement can also lead to the tooth shifting incorrectly or resulting in tooth loss.
Immediate Alternatives and Contacting Your Orthodontist
If you run out of your prescribed elastics, the most appropriate and safest step is to contact your orthodontist’s office immediately. The practice keeps meticulous records of the exact size, force, and brand of elastic you require for your personalized treatment plan. In most cases, the office can mail a replacement supply directly to you or arrange for a quick pickup. Until a new supply is secured, avoid attempting to substitute the elastics with any non-dental product. If the braces hardware is causing discomfort due to the missing band, a small piece of dental wax can be used as a temporary measure to cover a sharp edge.
