Types of Orthodontic Appliances — MBraces in Bristol, Rocky Hill & Waterbury, CT
Orthodontic treatment uses a variety of appliances — both fixed and removable — to guide teeth and jaws into their ideal positions. At Mbraces, Dr. Mazumder selects the appliances best suited to each patient’s specific diagnosis and treatment goals. Below is an overview of the most common appliances used in our Bristol, Rocky Hill, and Waterbury offices, along with guidance on how each one works and what to expect during treatment.
Elastics (Rubber Bands)
Orthodontic elastics — commonly called rubber bands — are small elastic loops that stretch between hooks on upper and lower brackets or bands. They are used to correct the fit between the upper and lower teeth, addressing overbite, underbite, and bite alignment issues that braces alone cannot fully correct. Elastics must be worn consistently and exactly as Dr. Mazumder prescribes in order to be effective. Wearing them only part of the time or stretching the same band too long before replacing it significantly reduces their effectiveness and can extend treatment time.
Headgear
Headgear is an external orthodontic appliance used to treat significant overbites (upper jaw forward of the lower) or underbites (lower jaw forward of the upper). It works by applying gentle, controlled force to restrict or redirect the growth of the upper jaw and upper teeth. Headgear is typically prescribed for growing children, as it takes advantage of the jaw’s natural development. It is most effective when worn consistently for the number of hours prescribed each day — usually during evening and nighttime hours.
Herbst® Appliance
The Herbst® appliance is a fixed orthodontic device used to reduce overbite by encouraging the lower jaw to grow forward while holding the upper molars back. Unlike headgear, the Herbst appliance is cemented to the teeth and works continuously — patients do not need to remember to wear it. It is used primarily for younger, still-growing patients and is typically worn for 12 to 15 months. Because it is fixed, patients adapt quickly and find it easy to incorporate into daily life. The Herbst appliance is often combined with full braces for comprehensive treatment.
Palatal Expander
A palatal expander is used to widen the upper jaw (palate) by gradually applying gentle pressure to the upper molars. This is done to create more space for crowded teeth, correct posterior crossbites, and improve the relationship between the upper and lower jaws. Dr. Mazumder will provide specific instructions on when and how to adjust your expander using a small key. Once the desired expansion is achieved, the expander remains in place for several additional months to allow new bone to form in the expanded area, solidifying the correction and preventing regression.
Retainers
Retainers are one of the most important parts of orthodontic treatment — and they come after the braces come off. Once teeth have been moved into their new positions, they need time to stabilize as the surrounding bone and tissues adapt. Without a retainer, teeth will gradually shift back toward their original positions, undoing months or years of treatment. Retainers may be removable (worn at home and at night) or fixed (thin wires bonded to the back of the teeth for continuous retention). Dr. Mazumder will provide detailed instructions on how long to wear your retainer and how to care for it. Consistent retainer wear is the key to maintaining your results for life.
Separators (Spacers)
Separators are small rubber doughnut-shaped pieces placed between the back teeth before orthodontic bands are fitted. They create a tiny gap between the teeth so that bands can be slipped on comfortably at the next appointment. Separators are typically left in place for one to two weeks and are removed just before banding. During this time, avoid sticky or chewy foods, toothpicks, and flossing the teeth where separators have been placed — these can dislodge them prematurely. Some mild pressure or soreness is normal and typically resolves within a few days.

Frequently Asked Questions — Types of Orthodontic Appliances
How important is it to wear my rubber bands as directed?
Extremely important. Elastics work only when worn consistently. Wearing them sporadically — or not at all between appointments — can significantly slow your treatment progress and in some cases reverse corrections that have already been made. Always follow Dr. Mazumder’s instructions about when and how long to wear your elastics.
How do I take care of a palatal expander?
Keep the expander clean by rinsing after meals and gently brushing around it with a soft toothbrush. Avoid very sticky or hard foods that could dislodge or damage it. Dr. Mazumder will show you exactly how to use the adjustment key and how often to activate the expander during your treatment phase.
Can I eat normally with a Herbst appliance?
Most patients adjust to the Herbst appliance within a few days and resume eating normally. As with all fixed orthodontic appliances, it is best to avoid hard, sticky, or chewy foods that could damage the appliance. Cut hard foods into small pieces and chew on both sides evenly.
How long do I need to wear my retainer after braces?
Retainer wear is typically most intensive immediately after treatment and gradually reduces over time. Many orthodontists recommend wearing a retainer at night indefinitely to prevent any shifting. Dr. Mazumder will provide a personalized retention protocol based on your specific treatment and the stability of your results.
What should I do if my separator falls out?
If a separator falls out a few days before your scheduled banding appointment and the gap between the teeth feels established, it may not need to be replaced. However, if it falls out early in the process, contact our office so we can assess whether replacement is necessary before your next visit.
Is headgear only for children?
Headgear is most effective during the growing years when jaw position can still be influenced by external forces. Adults can still benefit from certain types of orthodontic forces, but true skeletal headgear correction generally works best in children and early adolescents. Dr. Mazumder will determine the most appropriate treatment for each patient’s age and development stage.
Will I need all of these appliances during my treatment?
No. Most patients use only a subset of the appliances described on this page. The specific appliances you need depend entirely on your diagnosis. Dr. Mazumder will develop a customized treatment plan that includes only the tools necessary to achieve your goals safely and efficiently.
