Palatal Expanders

Help Teeth Grow in Comfortably

Palatal Expanders from Lehigh Valley Orthodontist

A lack of space in your child’s mouth can lead to crossbites or overcrowding. It is important to remediate issues such as these before your child’s jawbone stops growing. This is why you’ll find that many orthodontists, including Exeter Smiles, offer palatal expanders.

These expanders are a simple way to create more space in your child’s mouth, allowing their teeth to grow in straighter and more comfortably. They are typically worn before orthodontic treatment begins and are proven to help decrease the time a child may need to wear braces.

About Palatal Expanders

How do palatal expanders work?

Expanders are secured to the top of your child’s mouth and are cemented over several top teeth toward the back of their mouth.

Unlike adults, a child’s upper jaw is actually in two halves. Over time, these halves fuse together. Expanders help give the jaw more space before this happens.

The expander, which is custom made for each patient, comes in two halves. These halves are then connected by a screw at the roof of the mouth. This screw must be turned every day so that the jaw can expand.

How long must palatal expanders be worn?

Expanders are typically worn for a few months. This time period gives the jaw a chance to expand and gives new bone the opportunity to grow in the gap created by the expanders.

Are palatal expanders painful?

Patients may experience some discomfort after turning the expander’s screw. However, this discomfort is short lived.

Children may also have difficulty eating or speaking at first due to their tongue’s proximity to the expander. However, this difficulty only lasts a short time until they grow used to the expander.

Why may someone need a palatal expander?

The main reason a patient may need an expander is that their mouth is too small to allow for teeth to grow in comfortably.

Other reasons a child may need an expander is if they have:

  • A crossbite: When the upper jaw is smaller than the lower jaw, this can lead to uneven teeth and grinding.
  • Impacted teeth: An impacted tooth is a tooth that has yet to grow in, usually due to a lack of space. An expander can help give the tooth more room.
  • Overcrowding: The mouth is too small to allow for the proper growth of teeth. Overcrowding isn’t only painful, but can also make eating and talking difficult.

How old should a patient be for a palatal expander?

Palatal expanders are most effective in children before they reach puberty since their bones are still growing.

How much do palatal expanders cost?

If our orthodontists in Reading or elsewhere feel that your child requires palatal expanders, the price is included in the cost of braces.

Don’t take our word for it…

I had an amazing experience! All three of my kids received treatment. They love their results! This is my last child in treatment. She started with phase 1 and then rolled into phase2. Look at her amazing results.

Not quite finished with my treatment yet, but I’m blown away by the results so far. Not only are my results amazing but the staff here has been fantastic as well. Everyone I’ve came in contact with has been pleasant and made me feel welcome from the very start. Out of the 4 consultations at different orthodontists in the area, this was my top pick and I’m more the happy with the decision. Couldn’t thank this staff and Dr. Wegrzyniak enough for everything!
Hanna Shank
Exeter Smiles has been great to work with for my daughter’s braces. The braces are affordable and we had excellent service from Taneile in the Harrisburg office!!!!
Kimberly Henninger
I love this place! My appointments were super quick (under 15 minutes each time)! I had super nice people treat me. And I would definitely recommend to a friend!
Alex Freeland
I have 2 of my sons currently in treatment with the Harrisburg office - one with metal braces and one with Invisalign. Both treatments have gone so well. The staff is excellent - always welcoming and smiling. The process has been so easy. Their appointment times work well with our busy schedule. My teenager has so much more confidence with his smile and we are only halfway through his treatment. Very knowledgable and patient with question. Both boys and I recommend this office for any orthodontics needs.
Angelique Hogentogler
I am very pleased with my results. The staff and doctor were very professional. I am very sensitive, and they took their time in every appointment. Keep up the good work staff and doctor!

Sara Heffner
Dr. Wegrzyniak and her team have been amazing during my daughters treatment. Everyone is so nice when we are in the office and you can tell they really enjoy what they do. Insurance and financial department have been easy to work with. Have had changes with my debit card and insurance and they have helped me through that process.
Kyle Fizz
Beautiful office! Friendly staff and doctors! As a dental professional myself I chose to travel to Exeter orthodontics for the quality of work I see them produce for all the communities they serve. Their entire team is well educated and trained! If you are searching for braces go no further… they can provide high quality at an unbeatable price!
Nicole Callahan Tobias
Highly recommend Exeter Orthodontics! Started my braces journey at the beginning of this year (which I have been wanting to do for MANY years) and 9/30 they are coming off. The entire staff is very sweet and patient! Every time I come for my appointment it is hardly a wait Ever. I'm positive I will be very happy with my results. Thank you to all the staff here at the Allentown location.
Keyahra Jade
I am a fairly new patient at the Harrisburg office and have been very satisfied with the level of care and professionalism I have received since day one. Everything is well explained, thorough and affordable. If you need an unexpected appointment (which has happened to me twice now) they make you a priority and squeeze you in which is extremely appreciated! I had to schedule an unexpected appointment just today and Sherry (sp?) was kind, understanding and helpful in getting me scheduled asap. Dr. Wegrzyniak is super nice, knowledgeable and professional as well as the entire staff. I just wish I remembered everyone's names to list them here. I highly recommend Exeter Smiles! :)
Christine Phillips
Exeter Orthodontics have been amazing with my daughter for the last year. Flexible appointments, great prices, staff is so helpful with any questions you have. They always explain what they are doing. Highly recommend this office.
Stephanie Griffith
Every time I come in for an appointment I’m greeted with a smile 🙂 Dr. Wegrzyniak pays extra attention to detail and has always taken her time answering any questions (and trust me I always have a lot!!) I have. I have never felt rushed nor have I never waited more than 5 minutes for my appointment. It seems everyone who works here gets along well with each other and they are always willing and eager to give their co workers a hand if they need it. I would 100% recommend this business to anyone looking for orthodontic work. In a few years when my son is ready for braces, we will be bringing him here! Thank you for my beautiful smile Exeter team!

Chaselyn Holly
We go to the Lancaster office. The staff have been very kind. My son was very anxious about having braces put on but Dez made the experience easier by explaining everything she was doing prior to doing it. She made my son feel at ease and that meant a lot to me. The price is great too! I recommend this orthodontist.

My daughter has been a patient at Exeter Orthodontics for about 3 years now. She has had a wonderful experience. The staff has always been so pleasant and worked well with our schedules. They knew who she was every time she came in and made her feel very comfortable and at home. I would highly recommend this office for any of your orthodontic needs!
Valerie Miller
Always a pleasure to get my teeth worked on at Exeter Smiles! I have been to multiple locations and they are consistently great. I had braces put on as an adult which is not always fun, but it was a great experience because of the team at Exeter Smiles.
Victor Signorelli
We have absolutely fallen in love with exeter orthodontics after being referred here by so many people, my daughter has extreme fear of anything with a dentist and ortho, so I knew it was going to be an uphill battle, but at our consultation with Dr. Pardini and his assistant Chelsea that day they made her super comfortable and were able to really explain step by step. Then on her first day of actually getting the braces on, she had assistant Gabby who was very patient and helpful through all the tears and stress. While the initial thought and experience was not one my daughter preferred, she is now very comfortable with her situation and excited for her next appt.
Nikki Schlegel
I've been going to the Reading location for my braces since last May. All of the staff are so friendly and accommidating--I wish I got some of their names so I could address them in this review! But all of them are just wonderful there, I definitely recommend.

Dr. Pardini and Nick are always patient, kind, and go above and beyond for their patients. It's evident that Dr. Pardini truly cares about his work, and Nick is wonderful at explaining every detail of the Invisalign process. 10/10 would recommend
Ying-Kristine Wang
When I tell you that the staff, particularly Sam, was amazing and Dr. Pardini is always so engaging and informative. I’m 53yo and decided to do something I’ve always wanted and that’s to have a beautiful smile (to match my personality LOL). All of the staff are quite delightful and the affection they show one another is heartwarming. I actually look forward to my monthly adjustments! Thanks Y’all!!! Thanks SAMINTA!!!❤️
Katrina Cheatem
I brought my two boys ages 12 and 14 to Exter for a consultation to straighten their teeth. I was blown away by the customer service. Everyone was so accommodating and patient. The orthodontist explained each child's needs and our options for treatment were offered both verbally and in writing.
Jennifer Marie
Excellent care... we are treated well and we are seeing beautiful results. Other orthodontists dislike what Exeter is doing with their pricing... we love it!
M Riehl
I started my teeth straightening journey later in life as a 38 year old. I asked if that they get me done in under a year, so I could have a great smile for my wedding day. The team delivered! All of my visits were quick and professional. Without a shadow of a doubt, I would recommend Exeter Smiles.
Gene Bound
Great customer service and pricing. They always answer to all my concerns, Jenniffer at the front desk is amazing ! Would recommend this office always. Thank you for my nice smile !

Heather Charron
All the doctors and staff have been polite, friendly and always accommodating. The monthly payment made is very easy to afford getting my boys teeth looking great. So far we have one son who has completed the process and the other in the middle stages. Their teeth look amazing! I will definitely be bringing our daughter here when it's time. With them having multiple offices it makes it convenient to get in quickly when needed. Have and will continue to reccomend them.
Stephanie Vitalo
Very friendly, loved the positive vibes
Dusty Perez
My daughter had a wonderful experience with her braces and spacer! Was amazed how beautiful her smile is! Would recommend them to anyone! Definitely worth the money!!
Lenore Filipovic
Exeter orthodontics has been absolutely amazing through the entire experience. We started out young in place one due to my son having several teeth pulled and we needed a spacer to hold places for permanent teeth that would eventually come in n. Eventually we went into phase two and enjoyed going to every appointment the staff and doctors are all amazing . We recently started the retainer phase and I would high recommend exeter orthodontics . We have had most appointments at the Exeter office with an occasional trip to a few other offices since mY child seems to have killer bite and is extremely hard on devices… if you want a great experience go to Exeter orthodontics … my niece was also a patient and had the same great experience. Also I tried two other orthodontists before choosing Exeter so I did my homework .. Highly recommend
Jaime Fick
Great service staff was very nice they explained everything with details.
Mely Diaz
Dr. Pardini and the team at Exeter Orthodontics in Exton offered me the BEST experience and the BEST price with Invisalign. After multiple consults for Invisalign with various offices in the area, I chose Exeter and I’m so glad I did. The team was always so welcoming and accommodating throughout the entire process. When one of my new trays didn’t fit, they got me a same day appointment within a couple of hours of me calling. All staff were extremely knowledgeable and confident in the care they provided. For anyone needing orthodontic care, I wouldn’t recommend anyone else! Thanks Exeter for giving me the dream smile I always wanted!
Bree Westcott
My daughter has been a patient at Exeter Smiles for 3 years. She completed phase one treatment and is now back for phase 2. All of the doctors and staff have been amazing. Very welcoming environment. Office is always clean. If we need to come in for a broken bracket or a wire poking they have been great with getting us in in a timely manner. Great price, great customer service, great staff. Overall, I would definitely recommend Exeter Smiles.

Lauren Hellerick
We highly recommend Dr. Pardini as the Best Orthodontist. My son had several incidences with broken brackets due to eating hard food, he was immediately seen by Dr. Pardini. Dr. Pardini is very detailed and spends quality time with my son who is afraid of getting braces. Dr. Pardini made it so much easy for my son to receive treatment at Exeter Orthodontics, The staff makes my son feel at home. I would never have thought that my son would say that he LOVE going to the orthodontist, but he did. Exeter Orthodontics is the BEST in PA.and we thank Dr. Pardini for all his dedication and love for caring for patients.

Sara R
This office is amazing! My son, Grant has just started with his braces and they are always responsive and kind. Morgan rocks! Always helpful and quick regarding financial stuff!!

I would highly recommend Exeter Smiles to anyone who is looking for a great orthodontist. 3 of my children have had braces here and I recently went in to have some orthodontic work done. They were very kind and courteous and went above and beyond with my appointment. Dr. Mills is terrific and I appreciate her caring demeanor. Finally, one of my daughter's soccer team is heading to Nationals for US Youth Soccer and the the office was kind enough to be one of her team's sponsors.
