What to Expect With Your Child’s Palatal Expander




One of the most common orthodontic appliances used in young and growing children is the palatal expander. These appliances can look a little intimidating and barbaric at first to patients and parents and the very thought of having to “do the turns” every day at home can seem scary to a lot of parents. Trust me, they are not as bad as they seem.  I have been using expanders successfully in my practice for years and have been thrilled at how well they work for my patients.  So I wanted to share some things with those of you who might have just received, or will be receiving your expander on what can you can expect of having an expander as part of your orthodontic treatment?
Arch expansion is one of the most common ways to eliminate crowding and correcting crossbites in growing patients. I call it a game changer in the realm of orthodontics.  Expanders can easily solve some orthodontic problems that were difficult to solve in orthodontic cases of the past. Expanders have greatly reduced the need for routine extractions, and have eliminated the need for many jaw surgical procedures.
To work successfully, palatal expansion requires that the growth plate in the roof of the mouth (specifically, the mid-palatal suture) has not yet fused. Typically, this fusion usually occurs between 12 and 16 years of age, and usually occurs earlier in girls than in boys.

An expander is attached to the upper arch by bands placed around the upper first molar teeth. There are many variations of expanders being used today in modern orthodontic offices, but at Wheeler Orthodontics we prefers the “HYRAX”—which is short for HYgenic RApid eXpander.  Although there are removable expanders on the market, glued in ones have a very important advantage in that they cannot be lost, taken out, or forgotten.  Hyrax-expanders are easily cleaned!  Also important is that glued in expanders like the HYRAX maintain an intimate contact with the teeth, and the gentle force of the expansion does not overpower the ability of a removable expander to maintain its position in the mouth, where removable ones can be easily dislodged.

While there may be some initial discomfort right after an expander has been placed--just because there has never been anything like that attached to the teeth before--for the most part upper arch expansion is painless. Patients report that they feel a little “pressure” on the teeth, in the roof of the mouth, behind the nose, and even between the eyes as their expander is activated. This pressure fades within minutes.  And keep in mind that an expander does its job in about 3-4 months, then it is removed, so it is not in the mouth for a long time.

Besides pressure, you can also expect your child to speak a little funny for the first couple of days—which will quickly pass.  Additionally, you may hear them slurping as their mouth creates extra saliva after expander cementation. One of the most visible signs that the suture is opening (the desired effect) is the appearance of a space between the upper central incisors. The space is created as the expander pushes the two halves of the palate in opposite directions. Once you have stopped activating the expander, it is normal for the space to close quickly. This occurs by active closing forces that the braces will provide, combined with the help of elastic fibers in the surrounding gum tissues together working to return the teeth together and to close the gap. 

To make the first couple of days more bearable for your child as they adapt to their new expander, you may want to find some fun foods for them to eat that don’t require a lot of chewing. Examples include yogurt, pudding, mashed potatoes, ice cream, etc. A day or two after their delivery appointment, the expander will feel natural in their mouth and normal eating will resume. While expanders are more forgiving of hard and sticky foods than are braces, it is still recommended that patient avoid anything that would get stuck in the expansion screw.  However, we got you covered that situation, as we will give you a gadget that will help you remove anything that gets accidentally stuck around the expander.
Because there is always a potential relapse (movement back towards the original size) if expansion is made to fast, Dr. Wheeler recommends that the expander is only turned once every other day.  This allows for a nice, continuous, and harmonious rate of expansion that is biologically compatible with the tissue of the growth plate and your child’s inherent rate of growth.

One really cool thing expanders can do, besides the obvious effect of making room for the eruption of permanent teeth and in creating jaw harmony, is the ability an expander has of widening the nasal passages and upper airway.  The bone of the palate, is the same bone that makes the floor of the nasal passages.  So orthodontically widening the palate also widens the nasal airway. So you might see this nice side-effect:  Improved nasal breathing in your child.  This improvement can be significant! This can have a life-long improvement in reducing the risk of sleep apnea, sinus and ear infections, mouth-breathing, and snoring, especially as your child moves into adulthood. Sleep can be improved!!

  1. Thank you for the information! My friend was telling me that they have orthodontic plates. Is that the same as the expander? Should I go ask the guys at Perth Smiles?

  2. I'm getting ready to take my son in to talk with an orthodontist in the next week or so. I'm fairly sure that he'll need a palatal expander like that before he ends up getting braces. I'm glad I have a better idea of what to expect with it now than I did before.

  3. I really appreciate you sharing this awesome info! My brother just found out that he needs to get braces, and is way nervous about it. We are looking around trying to find a quality orthodontist that will make him feel better about it all, but we aren't sure what to look for. This helped a ton though, and I feel confident that we will find one soon.

  4. Thank you for your comments. I am happy that the information was useful to you. Using a palatal expander for your child will surely enhance your orthodontist's ability to achieve an excellent orthodontic result. An expander's success comes from its ability to harness your child's inherent growth potential to help tooth movement. By making appropriate room for erupting teeth, long-term stability, function, and esthetics are enhanced.

  5. My daughter's orthodontist recommended a palatal expander, and I've been a little worried. Knowing that the device will work in just a few months is a big relief! Hopefully the pressure created when it is put in won't last very long. http://www.arapahoeorthodontics.com/service/

  20. Upper jaw expansion is a form of orthodontic treatment that is used in specific cases. By widening the circumference of the palate, the perimeter of the dental arch increases to create more space for teeth growth. http://www.southairdriesmiles.com/orthodontics/ orthodontics.

  22. Hello. We had an hyrax installed with our 11 yrs old daughter. After a week or two she got sore nose and a bump on it. We can clearly see that her nose got wider. It looks a bit like a boxer's nose, but not as bad. We are considering to remove the hyrax and hope the process is reversible. Any thoughts about this??

  25. Unfortunately there are a lot of AIDS/Herpes denials on Herbal cures still out there. I did research on them after I was tested HIV/Herpes positive I was so worried am I going to die soon. I continue my search again on herbal remedy for Std, then I found lots of testimony on how Dr Itua Herbal Medicine Cured HIV/Aids, Herpes Virus,Copd, Hepatitis, Diabetes, On websites sharing their testimonies, which made much more sense to me. All the authors pronounce Dr Itua As a man with Good Heart, I pick interest in their testimonies and I contact him about my situation then he gave me procedure how it works, I proceed after one week he courier his Herbal Medicine to me and instruct me on how to drink it for two weeks to cure. I receive His Herbal Medicine so I drank it for two weeks as I was told then after 2 days I go for a test I found out I was cured from HIV/Aids & Herpes Virus, I pay homage to him 2 months ago to his country to celebrate with him on his African festival which he told me it usually happens every year. I know there are lots of (HIV)/Aids&Herpes Virus denials of Herbal Remedy movement the same few doctors and they represent a very small faction of the community. I could have died because I refused Natural Herbs Cures for so long, but luckily, by the grace of God I am alive to tell my story.

  28. I am not sure of the cause of COPD emphysema in my case. I smoked pack a day for 12 or 13 years, but quit 40 years ago. I have been an outdoor person all my adult life. Coughing started last summer producing thick mucus, greenish tint to clear. I tried prednisone and antibiotics, but no change. X-rays are negative, heart lungs and blood and serum chemistries all are normal. I have lung calcification from childhood bout with histoplasmosis.
