Retainers & Appliances

Retainers

When we remove your braces, we will begin the retention stage of your treatment. The retention phase lasts for a minimum of 24 months. Your final orthodontic result depends on your retainers, so follow through with the hard work you’ve put in so far. Remember to remove your retainer before brushing, and brush your retainer before placing it back in your mouth.

Hawley Retainer

The Hawley retainer, one of the most common types, is a removable retainer made of a combination of metal wires and sturdy acrylic, and is designed to keep your teeth in place. This retainer is specially made from impressions of your teeth so that it fits snugly and comfortably in the roof of your mouth, while any wire or acrylic framing keeps your teeth in perfect position. The acrylic can also be personalized with a large number of colors and/or patterns.


Essix Retainer

The Essix retainer is a transparent removable retainer that fits over the entire arch of teeth. Similar to Invisalign® trays, Essix retainers have no wires. They are inexpensive and easier to wear. They can be used for other treatments as well, including tooth movement and bridges.





Lingual Bonded

Bonded lingual retainers are cemented directly to the inside surface of your lower canines (eye teeth). This is one of the best ways to prevent your lower teeth from shifting as it is permanently attached! Patients with bonded lingual retainers must be careful with their bite as the bonding material may break due to incorrect biting and cause teeth to shift quickly. As with removable retainers, it is important to keep them clean. When brushing, make sure to carefully clean the inside of your lower teeth as well as the wire.

If your retainer breaks at any time during treatment, please do not adjust it yourself. Call us immediately to schedule an emergency appointment.

Appliances

Headgear | Herbst Appliance | Nance Appliance | Thumb/Finger Appliance
Lip Bumper | Tongue Thrusting Appliance

Headgear

Headgear is often used to correct an excessive overbite. This is done by placing pressure against the upper teeth and jaw, which would hold the teeth in position or help move them into better positions. The severity of the problem determines the length of time headgear needs to be worn. The key to success with your headgear appliance is consistency. Headgear must be worn a certain number of hours per day, and if not, it must be made up the following day.

Headgear should never be worn while playing sports and should also be removed while eating or brushing your teeth.


Herbst Appliance

One of the most common problems orthodontists treat is the discrepancy that occurs when the upper teeth protrude beyond the lower. Ordinarily, when we see a patient with the upper teeth protruding, we tend to think that the upper jaw and teeth are too far forward; but, more often than not, this condition is due to a small lower jaw that is further back than it should be. With these patients, we would like to encourage the lower jaw to catch up in growth, and braces like the Herbst appliance help this happen.

Even though the Herbst appliance prevents the lower jaw from moving backward, opening and closing movement still occur easily, and patients do not have any problems learning to chew their food with their lower jaw in this new position.

As with all kinds of braces, patients with Herbst appliances need to be careful about what they eat. For instance, cold foods such as ice slushes, Popsicles and ice will freeze the cement and make the brace loosen. Sticky foods such as caramels, bubble gum and candy suckers will pull the brace away from the teeth. Hard foods like crisp vegetables and hard candies will bend and loosen the Herbst appliance, too. So stay away from these foods during your orthodontic treatment.

Your Herbst appliance will be checked and adjusted at your appointments. If, sometimes between appointments, you develop some sore areas on the inside of your cheeks, please do not try to adjust the appliance yourself. Call for an appointment so that the necessary adjustments can be made.


Nance Appliance

The Nance Appliance is used to prevent upper molars from rotating or moving forward after you’ve worn a headgear, a Wilson’s arch or any other appliance to move your molars back. Some patients wear the Nance Appliance while they are awaiting their bicuspids to grow into place.

The appliance is made of two bands that are cemented onto the first molars and a wire spans the roof of the mouth from one molar to the other. An acrylic pad or “button” covers the wire that touches the roof of your mouth directly behind your front teeth.

Patients should always brush around the bands daily. Do not eat sticky, chewy candy as it can loosen your appliance.


Thumb/Finger Appliance

Sucking is a natural reflex that relaxes and comforts babies and toddlers. Children usually cease thumb sucking when the permanent front teeth are ready to erupt. Typically, children stop between the ages of 2 and 4 years. Thumb sucking that persists beyond the eruption of primary teeth can cause improper growth of the mouth and misalignment of the teeth. If you notice prolonged and/or vigorous thumb sucking behavior in your child, talk to your dentist.

One solution to thumb sucking is an appliance called a "fixed palatal crib." This appliance is put on the child's upper teeth by an orthodontist. It’s placed behind on the upper teeth on the roof of the mouth. The crib consists of semicircular stainless steel wires that are fastened to molars using steel bands. The stainless steel wires fit behind the child's upper front teeth, and they are barely visible. The crib usually stops the habit of thumb sucking within the first day of use.


Lip Bumpers

We like to avoid pulling teeth as often as possible, so we use lip bumpers on our patients who need to create more room for their crowded teeth. The lip bumper is a wire on the lower jaw that extends from one molar to another and keeps lips and cheeks from touching your teeth. When you move your mouth or speak, your lips and cheeks push on the bumper, and the bumper applies pressure to the teeth. This pressure pushes the molars back, creating more space for overcrowded teeth.

If you have a lip bumper, please remember to leave it in while eating, but do not eat hard or sticky foods. Proper, thorough brushing should remove any food that gets stuck in your lip bumper.


Tongue Thrusting Appliance

Tongue thrusting occurs when the patient presses his or her tongue against the front teeth, usually when swallowing, speaking or resting the tongue. If thrusting is constant, this can cause problems with teeth alignment and must be fixed.

We prefer to correct tongue thrusting by giving patients a tongue thrusting appliance. This appliance, similar to a mouth guard, is usually worn at night. Other times, a more permanent appliance is prescribed and can be only be adjusted by our office.
