MARPE in Denver: Adult Palate Expansion Without Jaw Surgery

You sleep eight hours and still wake up tired

A lot of adults have lived with the same things for so long that they have started to call them normal. Waking up with a dry mouth. A partner who says you snore, or that you stop breathing for a second. Clenching your jaw. Headaches that show up before lunch. Feeling foggy no matter how early you went to bed. These are common, but common is not the same as healthy, and they can sometimes be connected to an upper jaw that developed too narrow, leaving less room for nasal breathing and tongue posture.

• You wake up tired even after a full night of sleep
• You breathe through your mouth or wake up with a dry mouth
• A partner notices snoring or pauses in your breathing
• You clench or grind, or your teeth are worn down
• Your palate is high and narrow, or your teeth feel crowded
• You were told braces alone would not fix your bite or breathing

If three or more of these sound like you, it is worth understanding why. The good news is that even though your jaw stopped growing years ago, there is now a way to widen the upper jaw in adults without traditional jaw surgery. If you are looking for an adult palate expander in Denver, MARPE is one of the main non-surgical options we evaluate for narrow upper jaws.

Straight teeth do not always mean a healthy airway

This is the part most people are never told. Braces and clear aligners move teeth, but they do not change the structure of the jaw itself. You can have a perfectly straight smile and still have an upper jaw that is too narrow, sitting too far back, or both, quietly limiting the space your airway has to work with.

When the upper jaw is narrow, the floor of the nose is narrow too. That means smaller nasal passages, more resistance when you try to breathe through your nose, and a tongue that has nowhere good to rest. Over time the body compensates in ways you can feel: mouth breathing, clenching and grinding, tight muscles in the head and neck, and broken-up sleep. Addressing the teeth without addressing the structure underneath leaves the real cause in place.

Not all airway trouble is full sleep apnea

One thing that surprises a lot of adults is that airway problems sit on a spectrum, and you do not have to have sleep apnea, or even snore, to be affected. It runs from normal breathing, through snoring, to something called upper airway resistance syndrome, and then to obstructive sleep apnea. Many people land in the middle and have never been told there is a name for it.

This matters for MARPE because widening a narrow upper jaw tends to help most on the earlier end of that spectrum, narrow jaws, nasal restriction, and milder breathing concerns. Knowing where you fall is the first step, which is why a proper evaluation, and a sleep study when one is warranted, comes before any talk of treatment.

What MARPE is, in plain English

MARPE stands for miniscrew-assisted palatal expansion. You may also see it written as MASPE. They are the same appliance, the difference is only the pace: the R is for rapid expansion and the S is for slow. Dr. Vanderstelt almost always uses a slower rate of expansion now, because it is gentler on the bone and the surrounding tissue and is generally safer. The appliance itself is a custom, 3D-designed expander attached to the upper jaw using a few small temporary screws, anywhere from four to ten depending on your age and bone thickness. Because the screws anchor into bone rather than only pushing on teeth, it can gradually open the natural seam in the roof of the mouth in adults, the same expansion that used to require surgery.

MARPE compared to your other options

There is no single treatment that fixes the airway for everyone. The right path depends on your anatomy, your symptoms, and what a proper diagnosis shows. Here is how the main options compare at a high level.

Often the best outcomes come from a team: an orthodontist for the structure, plus ENT and sleep physicians, and sometimes a myofunctional therapist for tongue and breathing habits. Dr. Vanderstelt’s role is to evaluate the jaw and airway and guide you through that process rather than send you to a single device and hope it works.

MARPE vs jaw surgery for adults

A lot of adults arrive having been told that jaw surgery is their only option for a narrow palate, and the relief on their face when they learn that is not always true is the reason this section exists. MARPE and jaw surgery solve different problems. Neither is automatically better. The right answer depends on what your 3D imaging shows about the width and the front-to-back position of your jaws.

Sometimes the honest answer is a combination, or a referral, and Dr. Vanderstelt would rather tell you that than sell you an expander that cannot do the job. You can read more about how the jaw and airway are evaluated together on the orthodontic treatments page, or see a plain-English primer on how jaw expanders work before any treatment is chosen.

An orthodontist who is going through it too

Most orthodontists who offer MARPE have never worn one. Dr. Vanderstelt is a board-certified orthodontist with training in airway-focused care, and she is personally undergoing the same adult MARPE treatment she recommends to her patients. She can tell you what the first day actually feels like, what the activations are like, and what to expect along the way, because she lived it.

Common questions about MARPE in Denver

Common questions about MARPE in Denver

Can adults really get a palate expander, or is it only for kids?

Yes, adults can. Traditional expanders relied on the jaw still growing, which is why they were used in children. MARPE anchors into the bone with small temporary screws, so it can open the seam in the roof of the mouth even after the jaw has matured. For some adult patients, this may allow skeletal expansion without traditional jaw surgery.

How do I know if my upper jaw is too narrow?

Some common signs are a high, narrow palate, crowded teeth or teeth that were crowded before braces, a crossbite, chronic mouth breathing, and a tongue that does not have room to rest against the roof of the mouth. None of these confirm it on their own. The only way to know is a 3D look at the actual width of your jaw and nasal floor, which is part of the workup at your first visit.

Is there an age limit for MARPE?

There is no strict cutoff, but biology matters. The seam in the roof of the mouth fuses more firmly with age, so older adults sometimes need more screws for anchorage, and in some cases a small surgical assist to help the expansion. Dr. Vanderstelt uses your 3D imaging to see how mature that seam is and to give you a realistic picture of what to expect for your age and anatomy.

How long does MARPE treatment take in adults?

With the slower, gentler expansion Dr. Vanderstelt favors, the active widening happens over a span of weeks to a few months through small activations at home. After that, the expander stays in place to let new bone fill in and stabilize, typically around nine to twelve months total. Your exact timeline depends on how much expansion you need and how your bone responds, which Dr. Vanderstelt reviews with you using your 3D scan.

Does MARPE hurt?

The small screws are placed with the palate numbed for comfort, similar to other dental anesthetic. Most people describe pressure rather than pain during the turns, and any soreness is usually manageable with over-the-counter pain relievers for a few days. Dr. Vanderstelt has the expander herself, so she can walk you through exactly what to expect. If you are weighing comfort more broadly, this overview of whether orthodontic treatment is painful goes into more detail.

Will MARPE cure my sleep apnea or stop my snoring?

MARPE is not a stand-alone cure for sleep apnea, and any honest provider will tell you that. By widening the upper jaw and nasal passageway it can improve nasal airflow and is most appropriate for narrow jaws, nasal restriction, and milder breathing concerns. A sleep study is needed to understand the full picture, and more significant cases may need jaw surgery or a team approach with ENT and sleep physicians.

MARPE or jaw surgery, which one do I need?

It depends on whether your issue is width or position. MARPE widens a narrow upper jaw without an operating room and works well for nasal airway restriction and crowding. Jaw surgery moves recessed jaws forward and is the better fit when the airway behind the tongue is the bottleneck or when the bite problem is more significant. Many adults who were told surgery was their only option turn out to be candidates for MARPE, but the honest answer for your case comes from your 3D imaging.

How much does MARPE cost in Denver?

The cost of adult palate expansion with MARPE depends on case complexity, whether surgical assistance is needed for screw placement, and the length of follow-up orthodontic treatment. At Aligned Orthodontics on South Pearl Street, pricing is reviewed in detail at your consultation, and flexible payment plans are available to fit different budgets. Insurance coverage for airway treatment varies, so coverage is best discussed for your specific situation at the visit.

What happens at the first appointment?

Dr. Vanderstelt does a thorough evaluation of your bite, facial structure, and airway, including a low-radiation 3D CBCT image and an iTero digital scan of your teeth. You can read more about how 3D imaging guides modern orthodontics. From there you look at the imaging together and talk through whether MARPE, another option, or a referral to a partner provider makes the most sense for your goals.

Where is the office and who do you serve?

Aligned Orthodontics is at 1215 S Pearl Street in the Platt Park neighborhood of south Denver, near Wash Park and just south of I-25. Patients travel in from across the Denver metro, including Washington Park, University Park, Cherry Creek, and the DU community, for airway-focused orthodontic care.
