What is a Bite Block?

As effective as braces are, sometimes they need a little help. Bite blocks, also known as a ramp or turbo, prevent damage to metal braces by restricting the upper and lower teeth from touching. The material is a moldable acrylic plastic that shapes to your teeth and prevents them from coming in contact with the brackets. The plastic is durable enough to withstand pressure from eating and is available in various colors—they can even match the shade of a tooth.

The main functions of bite blocks are to correct a misaligned bite and protect braces brackets. They also help to prevent damage to your teeth while they move during orthodontic treatment. In many cases, the way your top and bottom teeth come in contact can slow the progress of your braces treatment, and an untreated deep bite can result in gum disease and enamel wear, according to the American Orthodontics Association. To keep your braces in working condition, an orthodontist will likely apply bite blocks to either the front two teeth or on the chewing surfaces of your molars so your braces can do their job without interruption.

If your dental professional recommends bite blocks as part of your orthodontic treatment, know that bite blocks are typically only necessary for roughly six to twelve months. You will only need bite blocks until your teeth move into a healthy alignment or your teeth no longer come in contact with the brackets when biting down.
