Eating with a Palatal Expander: What to Expect & How to Adjust

Getting a palatal expander can feel like a big step in your orthodontic journey—especially during the first few days when you’re adjusting to something new in your mouth. Many patients at Mellion Orthodontics ask how this device will affect daily routines like eating, chewing, and speaking.

If you’re wondering how to eat with an expander, you’re definitely not alone. While the appliance may feel awkward initially, most people adjust quickly with a little practice and a few dietary changes. The key is to start slow, choose the right foods, and keep your expander clean after every meal.

What Does a Palatal Expander Do?

A palatal expander is an orthodontic appliance designed to gradually widen the upper jaw. This helps create more space in the mouth for proper tooth alignment, prevents crowding, and improves bite function. It’s commonly used in children and adolescents, but adults with certain conditions can also benefit from expansion therapy.

At Mellion Orthodontics, expanders are custom-fitted to each patient’s unique anatomy, ensuring a safe, comfortable, and effective treatment experience.

What Eating Feels Like After Getting an Expander

Eating with an expander is different at first because the appliance sits across the roof of your mouth, close to the tongue. After it’s placed, you may experience:

• A feeling of pressure or tightness when chewing
• Slight difficulty swallowing or forming certain words
• A temporary increase in saliva
• Food getting trapped in and around the appliance

These side effects are completely normal and typically go away within the first 7–10 days.

How to Eat with an Expander: Expert Tips

1. Stick to Soft Foods at First

Start with soft, easy-to-chew meals that don’t put much pressure on your teeth or palate. Ideal options include:

• Mashed potatoes
• Pasta
• Applesauce
• Yogurt
• Smoothies
• Scrambled eggs
• Cooked vegetables
• Soups and stews

These will help you ease into chewing while your mouth adjusts to the new appliance.

2. Cut Food into Small, Manageable Pieces

Large bites can be hard to manage with an expander in place. Use a knife and fork to cut food into small, bite-sized pieces, which are easier to chew and less likely to get stuck in the device.

3. Avoid Sticky, Crunchy, or Hard Foods

Certain foods can damage the expander or make oral hygiene difficult. Avoid:

• Gum
• Caramel or taffy
• Popcorn
• Nuts
• Hard pretzels or chips
• Raw carrots or apples (unless cut thin or cooked)

Ask Mellion Orthodontics for a full list of foods to avoid based on your specific treatment.

4. Chew Slowly and Use Both Sides of Your Mouth

Chewing slowly helps you get used to the new sensation. Try to chew evenly on both sides of your mouth to avoid overloading one side or the other.

Hygiene Is Just as Important as Eating

With an expander in place, food particles can easily get trapped—especially near the center screw. Cleaning thoroughly after every meal is critical. Be sure to:

• Rinse your mouth with water or salt water
• Brush gently around the appliance with a soft toothbrush
• Use a floss threader or water flosser for hard-to-reach areas
• Consider an interdental brush for extra cleaning support

The team at Mellion Orthodontics can recommend the best hygiene tools for keeping your expander clean and comfortable.
