How Do Dental Braces Work

close up of bracesPeople need dental braces for a variety of reasons such as an overbite or an underbite, known as misaligned teeth or crooked teeth that need to be straightened for cosmetic or health reasons.

Your orthodontist will conduct a complete check of your teeth, this includes x-rays and teeth impressions. A treatment plan will then be made to decide what work is needed.

Dental braces work by applying continuous pressure to your teeth. Due to this pressure, over time the teeth will move in the direction that is desired.

Traditional dental braces have brackets and wires design.

Bracket Design

Each tooth that needs to be moved will have a bracket placed on it. This is a metal, rectangular shaped piece of apparatus that is attached to the tooth to enable wire to slide through.

The brackets are attached to the tooth enamel. A bracket is made for each tooth so that when the wire is placed into it, the tooth will start to moved into the desired position.

Arch Wire

The arch wire that is used is held in place by an elastic band. Arch wire is made from different materials and comes in a variety of sizes. The orthodontist rotates teeth to enable the tops of the teeth to align. Once the wire returns to it’s shape, the tooth will move to a more suitable position.

Wires are changed often. Smaller wires move up to thick, heavy, rectangular wires so that the slot of the bracket will move the tooth to where it should be. Heavy wire cannot be used at the start as it is unable to fit into the slot.

Bone Response

Bone remodeling enables tooth movement which is how dental braces are successful. The cells known as osteoblasts and osteoclasts are essential in successful correction of teeth.When the braces are applied, osteoblasts make new bone at the negative pressure part of the tooth and osteoclasts remove bone on the positive pressure side of the tooth. This is called bone deposition and reabsorption.

There are many types of dental braces. Your orthodontist will go over what type of dental braces would offer the best fit for your teeth. An experienced orthodontist will give you individual guidance to ensure the best possible results.
