If your orthodontist has recommended a Rapid Maxillary Expander (RME), you might have several questions about what to expect. This guide will walk you through everything you need to know from how long you’ll need to wear the appliance to the importance of proper oral hygiene during treatment.
How Long Do I Have to Wear the RME?
The RME is typically worn full-time for 3 to 9 months. The treatment consists of two phases:
- Activation Phase (First 2-3 Weeks)
- During this period, you will need to adjust the RME daily by turning the expansion screw. This process gradually widens the upper jaw by creating a small gap between the two halves of the upper jaw bone.
- Retention Phase (Remaining Months)
- After the desired expansion is achieved, the RME remains in place without further adjustments. This allows new bone to grow in the created space, stabilizing the expansion.
Once the expansion is complete, a fixed brace is often placed to maintain the width of the upper jaw and align the teeth properly.
Will I Need Another Brace Later?
Yes, in most cases, a fixed brace will be required after the RME treatment. This helps to straighten the teeth and maintain the newly widened arch.
Tooth Brushing & Oral Hygiene During RME Treatment
Maintaining excellent oral hygiene is essential while wearing an RME to prevent dental problems. Here are some important tips:
- Brush your teeth for at least 2 minutes, twice a day using a fluoride toothpaste.
- If possible, carry a toothbrush with you and brush after meals or snacks.
- Keep the RME clean to avoid plaque buildup, which can lead to decay and permanent damage to the teeth.
Failure to maintain good oral hygiene can result in cavities, gum disease, or staining around the appliance.
How Often Will I Need Appointments?
- Weekly appointments are usually required during the activation phase (first few weeks).
- Once the expansion is complete, appointments become less frequent but remain necessary to monitor progress.
Do I Still Need to See My Regular Dentist?
Yes! It is important to continue regular check-ups with your dentist during orthodontic treatment. Your dentist will monitor your teeth for signs of decay and other potential oral health issues.
What Should I Do If I Have a Problem with the RME?
If you experience any discomfort, breakage, or difficulty with the appliance, follow these steps:
- Stop turning the expansion screw immediately.
- Contact your orthodontist for an appointment as soon as possible.
- Do not wait for your next scheduled visit, as a damaged RME could delay your treatment or harm your teeth.
For urgent issues, reach out to your orthodontic clinic using their daytime emergency contact number.
What is the Purpose of RME?
Rapid Maxillary Expansion (RME), sometimes called rapid palatal expansion, is a technique used to widen (expand) the upper jaw (palate) when it is too narrow. This helps create more space for teeth to align properly and improves overall dental function.
How Does the RME Work?
Your upper jaw is made up of two halves, which are naturally joined in the middle. The RME appliance gently pushes these two halves apart and holds them in position while new bone fills in the gap under the gum.
Stages of Treatment
- Start of Treatment: The RME is placed and begins to expand the upper jaw.
- During Expansion: A small gap may appear between the two front teeth—this is normal and will close naturally within three months.
- After Widening is Complete: The appliance remains in place to allow bone to stabilize.
- Final Stage: A fixed brace is often needed to straighten the teeth and maintain the expansion.
What Are the Main Parts of an RME?
The RME appliance is a custom-made fixed brace designed to fit your mouth. It is attached to the upper teeth and cannot be removed.
Types of RME Designs
- RME with Metal Bands – A metal framework with an expansion screw in the center. It is attached to metal bands cemented onto the back teeth.
- RME with a Plastic Splint – Instead of metal bands, the appliance is cemented firmly to the back teeth using a plastic splint.
Expansion Screw
- The expansion screw in the middle of the RME must be turned twice a day or as instructed by your orthodontist.
- A special key is provided for this purpose.
How Long Do I Have to Wear the RME?
The RME needs to be worn full-time for 3 to 9 months, divided into two phases:
1. Activation Phase (First 2-3 Weeks)
- The expansion screw is turned daily to gradually widen the upper jaw.
2. Retention Phase (Remaining Months)
- The RME is left in place to allow new bone growth and stabilization.
Once the expansion is complete, a fixed brace is often used to maintain the width of the upper jaw and align the teeth properly.
Will I Need Another Brace Later?
Yes, in most cases, a fixed brace will be required after RME treatment. This helps to properly align the teeth and maintain the new arch width.
Will the RME Be Painful?
You may experience some discomfort for 3-5 days after the RME is fitted. This is normal and can be managed with:
- Mild painkillers (such as those used for headaches – follow dosage instructions).
- Orthodontic wax if the appliance rubs against your lips or cheeks.
- A temporary feeling of pressure on your teeth, which will ease as the upper jaw expands.
Can I Eat Normally with an RME?
Yes, but to protect your teeth and appliance, you should follow these dietary guidelines:
Avoid:
- Sugary snacks and drinks (especially between meals and at bedtime).
- Sticky or hard foods (such as caramel, gum, and mints).
- Fizzy drinks (even diet sodas) and excessive fruit juice.
Modify:
- Hard foods (such as apples, carrots, and crusty bread) should be cut into small pieces to prevent damage to the brace.
Tooth Brushing & Oral Hygiene During RME Treatment
Keeping your teeth and appliance clean is essential to prevent cavities and gum issues.
- Brush for at least 2 minutes, twice a day using fluoride toothpaste.
- Carry a toothbrush for use after meals or snacks.
- Ensure the RME appliance is clean to avoid plaque buildup.
⚠️ Failure to maintain proper oral hygiene can lead to permanent tooth damage.
How Often Will I Need Appointments?
- Weekly appointments are usually required during the activation phase.
- Once expansion is complete, visits become less frequent but remain essential for monitoring progress.
Do I Still Need to See My Regular Dentist?
Yes! Regular dental check-ups are important throughout your orthodontic treatment. Your dentist will monitor your teeth for decay and ensure they remain healthy.
What Should I Do If There Is a Problem with the RME?
If you experience any discomfort, breakage, or difficulty with the appliance, follow these steps:
- Stop turning the expansion screw immediately.
- Call your orthodontist for an appointment as soon as possible.
- Do not wait for your next scheduled visit, as a damaged RME could delay your treatment or harm your teeth.
For urgent issues, contact your orthodontic clinic’s daytime emergency number.
Final Thoughts
Undergoing Rapid Maxillary Expansion (RME) treatment is a crucial step in correcting jaw and teeth alignment. By following your orthodontist’s instructions, maintaining good oral hygiene, and attending regular check-ups, you can ensure a smooth and successful treatment process.
If you have any further questions or concerns about your treatment, don’t hesitate to speak with your orthodontist.
