Some of the most common orthodontic appliances used for pediatric patients or in orthodontics in general include: 

Herbst Appliance

In combination with braces, this alternative to traditional headgear helps correct overbites. Herbst appliances are attached to the molars, connecting the upper and lower jaw. This device correctly positions the upper and lower jaw to correct the bite. Benefits of this appliance include an average treatment time of 12 months, a less cumbersome appliance, and more comfortable treatment for patients. 

Palatal Expander

We utilize palatal expanders to help patients with small palates. A palatal expander stretches the palate, or the roof of the mouth, to make room for teeth to develop. Typically, we use a palatal expander for the upper jaw to gradually increase the palate.

We often use the palatal expander during phase one treatment to help young patients develop an even, healthy smile. Palatal expanders can help prevent the need for jaw surgery, braces, or even extractions later on.

Band & Loop (B & L)

A band and loop hold space for missing baby teeth in the back of the mouth until permanent teeth grow. The band and loop consist of a metal band that surrounds a tooth adjacent to a tooth gap. The band is connected to a loop that covers the space above the tooth gap.

Lower Lingual Arch (LLA)

A lower lingual arch is a metal appliance that helps maintain space in the lower teeth. The LLA has bands around the back molars and a wire that fits against the inside of the lower teeth. This appliance prevents the molars from moving forward. We use the LLA for children who have overcrowded teeth.


We recommend retainers for patients after they complete treatment with metal braces or Invisalign. Retainers hold teeth in their new positions to prevent shifting teeth. Wearing retainers as directed can keep teeth straight and prevent problems like an orthodontic relapse. It’s important for patients to wear their retainers as directed to keep teeth in place.
