Why SPEED?

SPEED Braces have revolutionized orthodontics by eliminating the need for the elastics that traditional braces require to straighten teeth. Instead, SPEED Braces use an energy-storing component called a ‘Spring Clip’ to straighten teeth. The SPEED Spring Clip works like a computer chip inside your braces. The Spring Clip is ‘programmed’ by your orthodontist when SPEED Braces are placed on your teeth. The Spring Clip, made of a ‘Super-Elastic’ space age material, then follows the programmed instructions by applying a light continuous force to gently move teeth to their correct position. Only SPEED Braces contain a ‘Super-Elastic’ Spring Clip. The result is greater comfort, and potentially fewer appointments and more ‘SPEEDy’ treatment. SPEED Braces are small; typically 1/3 smaller than traditional braces, and they look great! SPEED’s small footprint results in less food trapping, so good oral hygiene is easier to maintain throughout your treatment.
