It is common for orthodontists to see patients whose upper teeth protrude beyond the lower teeth. Typically, this condition is due to a small lower jaw that is positioned further back than it should be. At Sudbury Orthodontics, 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 don’t struggle to learn to chew their food with their lower jaw in this new position.

Wearing a Herbst Appliance

However, by simply practicing speaking/reading out loud, your speech will return to normal quickly. It’s also common to notice that you salivate more than you usually do, but this will decrease as you become accustomed to wearing the appliance.

It’s important for patients wearing a Herbst to avoid eating certain kinds of foods. Cold foods like frozen drinks, ice cream, and ice should not be consumed, because 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 you notice any soreness developing inside your cheeks, it’s important not to try to adjust the Herbst yourself at the risk of derailing your treatment plan. Instead, call our office for an appointment so we can make the necessary adjustments for you.

Forsus 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 until your teeth adjust and the pain subsides. If you have any discomfort, you can take regular over-the-counter anti-inflammatory medication for relief. Also make sure to clean the appliance regularly by gently brushing the coil and other metal pieces to remove any food particles or build-up.

The Forsus appliance can break so opening your mouth too wide, biting on the appliance, or playing with it is strongly discouraged. However, if your Forsus appliance does break, contact your Sudbury orthodontist immediately to schedule an appointment. Our friendly staff will ensure the Forsus is repaired quickly to get your treatment back on track.

Expansion Therapy

Opened mouth expansion therapy

The expansion appliance is designed to create a wider space in the upper jaw. This appliance is attached to the upper molars using 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.

Temporary Anchorage Devices – TADs

Teeth with traditional metal braces and temporary anchorage device - 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. However, TADs are now a better option as they are smaller, more discreet, and more efficient while also requiring less effort from the patient.

TADs are not recommended for all patients though. In fact, these anchorage devices may not be needed at all for some. If you would like more information about TADs and how they can potentially prevent you from needing orthodontic headgear, visit your Sudbury, Espanola, or Parry Sound orthodontist.
