Whether you need a Val Caron orthodontist for your child or are wondering if Invisalign is right for you, we can meet all your family's orthodontic needs. We strive to provide our patients with state-of-the-art treatments to help them obtain the healthy, straight smiles they deserve.

It is important to take good care of your orthodontic appliances and to follow the directions you receive from your orthodontist. Here is some information about orthodontic appliances and how to care for them.


It is common for orthodontists to see patients whose upper teeth protrude beyond the lower teeth. Most often, this condition is due to a small lower jaw that is positioned further back than it should be. We often have these patients wear the Herbst appliance that encourages the lower jaw to catch up in growth.

While the Herbst appliance is designed to prevent the lower jaw from moving backward, opening and closing movement still occurs easily so patients do not have any problems learning to chew their food with their lower jaw in this new position.

Patients wearing the Herbst appliance must avoid eating certain types of foods. Cold foods like frozen drinks, popsicles and ice must be not be eaten as they will freeze the cement and cause the brace to loosen. Other foods that should be avoided include sticky, chewy and hard foods that can bend and loosen the Herbst appliance.

Your orthodontist will check and adjust your Herbst appliance at your regular appointments. If at any time, you develop sore areas on the inside of your cheeks, do not try to adjust the appliance yourself. Instead, call our office for an appointment so we can make the necessary adjustments for you.

Wearing a Herbst Appliance

When you first start wearing the Herbst appliance, it is common for your mouth to feel full. Speaking will also seem awkward. However, by simply practicing speaking/reading out loud, your speech will return to normal quickly. It is also common to notice that you salivate more than you usually do, but this will decrease as you become accustomed to wearing the appliance.

forsusForsus Appliance

The Forsus appliance is designed to help move the upper molars back while moving the lower arch forward. This appliance, which is used while a patient is wearing braces, consists of a spring coil rod that runs from the upper first molar band down to the lower archwire.

You may notice some discomfort initially, so we recommend eating only soft foods for the first few days after the appliance is placed. If you have any discomfort, you can take regular anti-inflammatory medication for relief. It is important to clean the appliance regularly by gently brushing the coil and other metal pieces making up the appliance.

The Forsus appliance can break so opening your mouth too wide, biting on the appliance or playing with it may cause it to break. If your Forsus appliance does break, contact our office immediately to schedule an appointment so it can be repaired.

expanderExpansion Therapy

The expansion appliance is designed to create a wider space in the upper jaw. This appliance is attached to the upper molars via bonding or cemented bands. The expansion appliance is typically used when the upper jaw is too narrow for the lower jaw or when the upper teeth are crowded or blocked out by the dental arch.

The connective tissue between the left and right halves of the upper jaw is very responsive to expansion in patients who are still growing. Using a special key, the expansion appliance is activated by turning a screw in the center. This puts gradual outward pressure on the left and right halves of the upper jaw to increase the amount of bone growth between the right and left halves of the jaw, resulting in an increased width.

tadTemporary Anchorage Devices – TADs

Temporary anchorage devices or TADs are miniature screws that are positioned in the mouth to serve as fixed anchors for moving specific teeth in a very controlled, predictable manner. Before TADs were developed, headgear was used to move some teeth while keeping others in place or in patients with missing teeth. But TADs are now a better option as they are smaller, more discreet and more efficient while requiring less effort from the patient.

TADs are not recommended for all patients and in fact, these anchorage devices may not be needed at all. If you would like more information about TADs and how they can potentially prevent you from needing orthodontic headgear, please contact us.
