Getting a palate expander, MSE, or MARPE orthodontic appliance is an exciting step toward creating a healthier, more functional smile, but let’s be honest: eating with an expander can feel a little awkward at first.
Whether your child just started treatment with a traditional palate expander (RPE), or you’re adjusting to MARPE or MSE orthodontic treatment as an adult, it’s completely normal to need a little time to adapt.
Certain foods may suddenly feel difficult to chew, food can get stuck more easily, and speaking and swallowing may feel different for the first few days.
Fortunately, the adjustment period is temporary for most patients.
Customized Expansion Treatment for Kids, Teens & Adults
At Matsumoto Orthodontics & Periodontics, Dr. Matsumoto helps patients of all ages navigate expansion treatment comfortably and confidently.
As a board-certified orthodontist who is nationally recognized for MARPE and MSE treatment, he customizes every treatment plan based on the patient’s stage of growth, anatomy, and goals.
This guide will help you understand how to eat with an expander, what foods to avoid, and how to make the adjustment period easier. Let’s dive in:
TL;DR: Quick Tips for Eating with an Expander
- It’s normal for eating to feel awkward for the first few days after getting a palate expander, MARPE, or MSE appliance.
- Soft foods like yogurt, pasta, mashed potatoes, smoothies, soups, scrambled eggs, and soft fruits are usually easiest during the adjustment period.
- Sticky, crunchy, hard, and chewy foods are some of the main palate expander foods to avoid because they can damage the appliance or get trapped underneath it.
- Most patients begin feeling more comfortable eating with an expander within about 1–2 weeks.
- Taking smaller bites, chewing slowly, and drinking water while eating can make meals much easier.
- Food getting stuck in the appliance is completely normal, and using a Waterpik® or rinsing with water can help keep the appliance clean.
- Dr. Matsumoto customizes expansion treatment based on age and skeletal development, using RPE for younger children, MSE for skeletal maturing patients, and MARPE for adults and older teens.

Why Eating with an Expander Feels Different at First
Palate expanders work by gradually widening the upper jaw. Because the appliance sits against the roof of the mouth, your tongue suddenly has less room to move naturally at first.
This can temporarily affect:
- Chewing
- Swallowing
- Speech
- Tongue placement
- How food moves around your mouth
For many patients, the biggest challenge is simply learning a new “routine” for eating. Your tongue and muscles adapt quickly, but there’s definitely a short learning curve in the beginning.
Patients with MSE or MARPE appliances may also experience mild pressure or soreness during active expansion, especially after adjustments.
How long does it take to get used to eating with an expander?
One of the most common questions parents ask is: How long does it take to get used to eating with an expander?
For most patients:
- The first 3–5 days are the biggest adjustment period.
- Eating starts feeling noticeably easier within 1–2 weeks.
- Speaking and swallowing usually normalize fairly quickly as the tongue adapts.
Younger children often adapt surprisingly fast. Adults and teens in MARPE or MSE treatment may take a little longer to adjust because skeletal expansion in mature patients is typically more advanced.
The key is consistency. The more you practice eating and speaking normally, the faster your mouth learns to adapt.
A List of Foods to Eat with a Palate Expander
Choosing softer foods at first can make meals much more comfortable while adjusting to the appliance.
Here’s a helpful list of foods to eat with a palate expander:
Soft Breakfast Foods
- Scrambled eggs
- Oatmeal
- Pancakes
- Yogurt
- Smoothies
- Soft fruit
- Cottage cheese
Easy Lunch & Dinner Foods
- Pasta
- Rice
- Soft sandwiches
- Mac and cheese
- Soup
- Mashed potatoes
- Soft cooked vegetables
- Shredded chicken
- Meatballs
- Fish
Snacks & Treats
- Applesauce
- Pudding
- Ice cream
- Bananas
- Soft muffins
- Protein shakes
- Soft granola bars
As soreness decreases, most patients can gradually return to a more normal diet.
Which Foods to Avoid with a Palate Expander
Certain foods can bend, loosen, or damage the appliance, especially during the early stages of treatment.
Some of the main palate expander foods to avoid include:
Sticky Foods
- Gum
- Caramel
- Taffy
- Starburst®
- Gummy candy
Hard or Crunchy Foods
- Popcorn
- Ice
- Hard pretzels
- Nuts
- Chips
- Hard candy
Tough or Chewy Foods
- Bagels
- Thick pizza crust
- Beef jerky
- Tough steak
These foods can get stuck underneath the appliance or place excessive pressure on it.
Top Tips for Eating with an Expander
If meals feel frustrating at first, these simple tips for eating with an expander can help tremendously.
- Take Smaller Bites
Large bites are harder to control while your tongue is adjusting. Smaller bites make chewing easier and help prevent discomfort.
- Chew Slowly
Eating slowly gives your mouth more time to coordinate around the appliance. Most patients notice improvement quickly once they stop rushing meals.
- Drink Water While Eating
Water helps wash food away from the appliance and can make swallowing easier.
- Cut Food into Smaller Pieces
Especially during the first week, cutting foods into bite-sized pieces can make eating much more manageable.
- Use a Waterpik® or Rinse Frequently
Food getting trapped underneath the appliance is extremely common. A Waterpik® or thorough rinsing after meals helps keep the appliance clean and comfortable.
- Be Patient with Yourself
This adjustment period is temporary. Most patients improve dramatically within the first couple of weeks.
Different Palate Expanders for Different Stages of Growth
Expansion treatment is not one-size-fits-all. The right appliance depends on the patient’s age, stage of skeletal development, anatomy, and overall treatment goals.
As a board-certified orthodontist who is nationally recognized for MARPE and MSE treatment, Dr. Matsumoto custom-designs expansion treatment for children, teens, and adults using advanced imaging and highly individualized planning.
Different types of palate expanders include:
RPE (Rapid Palatal Expander)
Traditional palate expanders are typically used for younger children whose bones are still growing and more responsive to orthopedic expansion.
MSE (Maxillary Skeletal Expander)
MSE treatment is often recommended for skeletal maturing patients, including many teens and young adults who may require a more advanced form of expansion.
MARPE (Miniscrew-Assisted Rapid Palatal Expansion)
MARPE treatment is designed for skeletally mature older teens and adults. These fully customized appliances are used for more advanced expansion cases and are carefully tailored to the patient’s anatomy and treatment needs.
Because of Dr. Matsumoto’s unique dual training in orthodontics and periodontics, along with his nationally recognized expertise in MARPE and MSE treatment, patients travel from across the country to seek his advanced approach to expansion therapy.
