Schwarz Palatal Expander Appliance for Kids

What is the Schwarz Expander Appliance?

Upper Schwarz Appliance


The Schwarz appliance is a removable retainer-like device that straightens teeth by stimulating the jaws to slowly grow larger. More space in the mouth helps teeth fit better and be less crooked. The Schwarz stimulates the jaws and face to grow wider, taller and more forward. The result of therapy is more 3D space in the mouth and nasal passageways. Our Schwarz therapy helps our patients, not only have a better smile, but also sleep, breathe and posture in a healthier way.

The Schwarz is only worn at night and is taken out during the day. It is not worn while eating. Oral hygiene is very easy since the appliance is removable. The treatment does not hurt because expansion pressure is very light compared to braces and conventional orthodontics. As long as the appliance is worn every night, designed properly and adjusted as advised, the treatment will go as planned.


What is our Schwarz Therapy About?


Drs Gary Adams and Viet Le welcome you to our practice. If you are looking for information about the Schwarz appliance therapy, you have found the right place. Many of our patients are children who have crowded teeth, tied tongues, and mouth breathing problems. Some also have posture and sleep disordered breathing issues. We integrate orthodontic expanders (such as Schwarz), chiropractic services, breathing exercises and myofunctional or tongue correction therapy. Our therapy helps our patients have a straighter smile, sleep better and live a pain-free and healthier life. We are located in Vienna Virginia near Tysons Corner and just outside of Washington DC.


Goals of Schwarz Appliance Treatment:


  • Improve facial growth and profile
  • Improve smile
  • Optimize tongue function
  • Establish healthy breathing patterns
  • Create a good bite
  • Balance upper and lower jaw relationships
  • Establish healthy posture


Why Do Teeth Get Crooked?


Teeth become crooked because of poor tongue function, unhealthy mouth breathing patterns and a diet consisting of foods that are too soft. This is why kids mouths and faces do not grow large enough for all their teeth to fit and bite properly. If tongue and breathing problems are not corrected, your child will fall behind again in their development 1-2 years after appliance therapy. That is right, the teeth will get crowded and crooked all over again, if the root cause of developmental problems are not corrected. Kids continue to grow till at least the age of 19.


What Causes Small Jaws and Faces?


Poor tongue movement is the root cause of underdevelopment of the face. Tongue pressure naturally expands the mouth and lower part of the face. Tongue ties cause diminished range of motion of the tongue. The tongue does not move out far enough and cannot reach the palate easily. Tied tongues often get pointy and curl down when extended out of the mouth. There is a sequential cause and effect relationship in the following order:


  1. Tongue Tie
  2. Poor Tongue Function
  3. Under Development of the Palate and Nasal Passageways
  4. Poor Nasal Breathing
  5. Mouth Breathing


How to Correct Tongue Ties


Tongues can be untied with a soft tissue laser.  It is very quick, mostly painless and there is not bleeding. The dentist needs to verify the tongue is functioning correctly at the time of the procedure. Untying the tongue alone is not enough. The procedure is called a “functional tongue untie.”


What is Myofunctional Therapy


Myofunctional therapy is basically tongue physical therapy. Tongue exercises to achieve healthy movements. If tongue therapy and exercises are done with a functional untie procedure, tongue reattachment is less than 20%. Without myofunctional therapy, tongue reattachment is closer to 80%.


How to Correct Mouth Breathing Patterns


  1. Remove all Tongue Ties
  2. Myofunctional Therapy
  3. Orthodontic Expanders to correct jaw and facial under growth
  4. Breathing Exercises to restore proper nasal breathing patterns
  5. Posture Therapy with a chiropractor or qualified PT


The Lower Schwarz Device

Lower Schwarz Device


The lower Schwarz device stimulates the lower jaw to grow wider.  The mandible can also grow forward or anteriorly. Mandibular anterior growth is also called mandibular repositioning. Mandibular repositioning is done by adjusting the bite area on the upper appliance to a more forward position. This is also how the jaws grow naturally when things are growing normally.


Schwarz is our Favorite Kids Expander


The Schwarz is our most popular expansion appliance for children. Dr. Adams likes the Schwarz because it is very versatile and effective in a wide variety of different orthodontic cases. The Schwartz is very easy to tolerate because it only needs to be worn at night and it is removable. Unlike braces and other fixed expanders, the appliance does not get in the way of daily activities and is not worn during meal time. The appliance does not hurt when being adjusted.


Expanders We use for Children

  1. ALF appliance
  2. Myobrace
  3. Twin Block
  4. Crozat
  5. Healthy Start


What is An Expander Anyway?


We prefer the use of the term “growth appliances.”  They are small retainer-like devices that promote growth of the jaws. The goal is to grow the jaws into a more optimal size and shape. Growth appliances work by applying a light force in the direction the jaws need to grow. They are not mechanical devices and do not cause pain. The appliance mimics tongue pressure and encourages proper tongue position. Appliance therapy is synergistic with swallowing and tongue movement.


How Long is Schwarz Appliance Therapy?


Most kids only need to wear the appliances at night for 6-9 months during treatment. The appliances are usually not worn during the day or while eating. The patient is usually seen in the office every 5-7 weeks. During the office visits we will evaluate the growth, adjust the appliances and verify patient compliance. Treatment is usually performed between the ages of 5 and14 years of age.
