Orthodontic elastics, commonly known as rubber bands, are a highly effective component of treatment for patients undergoing braces or clear aligners. These small, removable bands are prescribed to correct bite alignment issues by addressing how the upper and lower teeth fit together. They apply targeted, gentle forces between the jaws, connecting hooks or buttons on the top teeth to those on the bottom in specific patterns. To answer the most pressing question directly: yes, you must sleep with your rubber bands on, as continuous wear is a non-negotiable requirement for treatment success, unless otherwise instructed by your orthodontist.
Required Duration of Elastic Wear
The effectiveness of orthodontic elastics is directly tied to the duration of their wear, making compliance paramount for a successful treatment outcome. Orthodontists typically prescribe an intensive schedule, requiring the elastics to be worn for 20 to 24 hours every day. This near-constant application of force ensures the teeth and jaw structures are under consistent pressure, guiding them into their correct positions.
Nighttime wear is a crucial component, as sleeping represents a substantial block of time utilized for tooth movement. Elastics should only be removed for eating, brushing, and flossing, and must be immediately replaced afterward. Failing to meet the daily requirement by skipping night wear will significantly slow down or stop progress, ultimately extending the time spent in treatment.
How Consistent Force Moves Teeth
The biological process allowing teeth to move through bone is called bone remodeling, which requires a gentle, continuous force to be effective. When elastics apply pressure, they stress the surrounding jawbone. This pressure triggers specialized cells called osteoclasts to break down bone tissue on the side of the tooth where the force is applied.
Simultaneously, on the opposite side where tension is created, osteoblasts form new bone tissue. This coordinated breakdown and rebuilding process allows the tooth to gradually shift into the newly created space, ensuring the bone supports the new alignment. If the elastic force is removed for an extended period, the bone remodeling process can stall or partially reverse. The surrounding tissues will attempt to settle back toward their original positions, undoing achieved movement and slowing future progress.
Troubleshooting Common Elastic Issues
Experiencing initial soreness is a common side effect as your mouth adjusts to the new forces, but this discomfort should diminish within two to three days. Over-the-counter pain relievers and consuming soft foods can help manage this temporary ache. Elastics lose strength and elasticity over time, so they must be changed completely at least once or twice a day to ensure the correct therapeutic force is maintained.
If an elastic band breaks or snaps, replace it immediately with a new one from your supply. Never attempt to double up on elastics to compensate for missed time or breakage, as using excessive force can damage the teeth and roots. If you temporarily forget to replace your elastics after a meal or brushing, simply resume wear immediately and commit to the full required duration for the rest of the day.
