Hyrax Expansion Appliance

  • The expansion appliance is an excellent appliance intended to widen the upper jaw.
  • Please activate the appliance once a day. Find a good time to activate the appliance and try to stick to that routine to avoid missing any activations. However, if you should miss an activation, do not activate it twice the next time.
  • Speaking with the appliance will take some getting used to. But it can be done, as all of our patients will verify.
  • Pressure will be felt on the teeth. Pressure might also be felt at the cheekbones or a tingling might be felt at the tip of the nose. These are all normal.
  • A dramatic space will appear between the two front teeth sometime in the first week or two. This is also normal, and will close later.
  • It is important that the appliance be kept very clean. Use your toothbrush vigorously. You will not jog it loose.
  • There are no dietary restrictions. However, we ask that you do not chew gum or have any sticky candy.
  • If necessary, Advil or Tylenol every 4 to 5 hours may be used.
  • If the expansion appliance should come loose, and they occasionally do, please call the office immediately to have it recemented. Do not continue to activate the appliance.
  • Please make sure you have another appointment scheduled. Careful monitoring of this fast acting appliance is critical.
  • If you should have any questions, please do not hesitate to call the office.
