Palate expanders are orthodontic devices used primarily in children to widen the upper jaw. By expanding the palate, these devices create more space in the mouth, which can help correct various dental issues such as crowded teeth, crossbites, and impacted teeth. Understanding the types of palate expanders, how to adjust them, and the best care tips can make the process smoother and more effective for both patients and their caregivers.
What Are Palate Expanders?
Palate expanders, also known as palatal expanders, are devices that gradually widen the upper jaw (the maxilla) over time. The goal is to increase the width of the mouth, allowing teeth to align properly and providing more room for new teeth to emerge. They are often used in paediatric dentistry because children’s bones are still growing and are more malleable, making it easier to correct alignment issues early.
Why Are Palate Expanders Needed?
There are several reasons why an orthodontist might recommend a palate expander:
- Crowded Teeth: When there isn’t enough space in the mouth for all the teeth to fit properly, a palate expander can create the necessary room.
- Crossbite: A crossbite occurs when the upper teeth sit inside the lower teeth when biting down. Expanding the palate can help align the teeth correctly.
- Impacted Teeth: If a tooth is trapped beneath the gums due to lack of space, expanding the palate can help the tooth emerge properly.
- Breathing Issues: In some cases, a narrow palate can lead to breathing problems, such as sleep apnoea. Expanding the palate can open up the airway and improve breathing.
Types of Palate Expanders
There are several types of palate expanders, each designed to address specific dental issues. Understanding the different options can help you and your orthodontist choose the best device.
1. Rapid Palatal Expander (RPE)
The Rapid Palatal Expander is one of the most commonly used devices. It consists of a screw located in the centre of the device, which is attached to the upper molars with metal bands. The screw is gradually turned, usually with a special key provided by the orthodontist, to widen the palate quickly over a short period.
2. Slow Palatal Expander (SPE)
The SPE works similarly to the RPE, but the expansion occurs more gradually. Instead of rapid adjustments, the screw is turned more slowly over a longer period, allowing for a more gradual widening of the palate.
3. Removable Palatal Expander
As the name suggests, these expanders are removable. It’s typically used for less severe cases and consists of a plastic body with metal springs or screws. The device is less invasive and allows for easier cleaning, but it requires discipline from the patient to wear it 24 hours a day.
4. Surgically Assisted Rapid Palatal Expander (SARPE)
In some cases, especially in adults where the palate has already fused, a Surgically Assisted RPE may be necessary. This procedure involves a minor surgical operation to separate the bones of the palate before using a palatal expander to achieve the desired width.
5. How to Adjust Palate Expanders
Adjusting a palate expander is a crucial part of the treatment process. The frequency and method of adjustments depend on the particular expander and the patient’s situation.
6. Adjusting a Rapid Palatal Expander
For an RPE, adjustments are usually made daily or every other day. The orthodontist will provide a special key that fits into the screw mechanism of the device. By turning the key as instructed, the screw is activated, gradually pushing the bones of the palate apart.
Step-by-Step Adjustment:
- Insert the key into the hole in the centre of the device.
- Gently push the key toward the back of the mouth until it stops.
- This will create a new hole.
- If you don’t complete the rotation, the new hole won’t appear.
- Remove the key carefully without reversing the turn.
- Repeat the process as instructed by the orthodontist.
Adjusting a Slow Palatal Expander
The process for adjusting an SPE is similar to that of an RPE, but the adjustments are made less frequently. Your orthodontist will provide instructions based on your treatment plan.
Removable Palatal Expander Adjustments
For a removable expander, adjustments may be made by the orthodontist during regular visits, or they may provide instructions for at-home adjustments. It’s important to follow the orthodontist’s guidance carefully to ensure the device works effectively.
Post-Surgical Adjustments for SARPE
For those with a SARPE, adjustments typically begin a few days after surgery, under the close supervision of the orthodontist. The adjustments are usually similar to those of an RPE, but the orthodontist may make the initial turns to ensure proper healing.
Caring for Your Palate Expander
Proper care of your palate expander is essential to ensure the device works effectively and to maintain good oral hygiene. Here are some tips to help you care for your expander:
Maintain Good Oral Hygiene
Brushing your teeth and the expander itself is crucial. Food particles can easily get stuck in the expander, leading to plaque buildup and potential cavities.
Brushing Tips:
– Use a soft-bristled toothbrush to clean around the expander.
– Consider using a water flosser to clean hard-to-reach areas.
Avoid Hard or Sticky Foods
Certain foods can damage the expander or get stuck in the device, making it difficult to clean. Avoid hard foods like nuts and sticky foods like caramel to prevent any issues.
Foods to Avoid:
– Popcorn
– Chewing gum
– Hard candies
– Sticky toffees
Monitor for Discomfort
It’s normal to experience some discomfort after adjusting the expander, but severe pain or irritation should be reported to your orthodontist. They may need to adjust the device or provide additional care to alleviate the discomfort.
Signs of Concern:
– Persistent pain
– Swollen or bleeding gums
– Difficulty swallowing
Follow Up with Your Orthodontist
Regular check-ups with your orthodontist are crucial to monitor the progress of your treatment. They will ensure the expander is working correctly and make any necessary adjustments.
