Your Local Palo Alto Orthodontist
When it comes to orthodontics, one of the most effective tools we use to create beautiful smiles is the orthodontic expander. At Twin Smiles Orthodontics in Palo Alto, we specialize in creating customized treatment plans that address a wide range of dental concerns. Whether your child needs kids braces, a kids orthodontist, or an RPE orthodontic appliance, we offer a variety of solutions to help improve their oral health and appearance. In this blog post, we’ll explain how an orthodontic expander works, when it’s needed, and how it can benefit your child’s smile.
An orthodontic expander is a dental device used primarily to widen the upper jaw. It’s especially useful for patients whose upper jaw is too narrow, which can cause dental crowding, bite problems, or other orthodontic issues. The expander is typically used in growing children, as it is most effective during the early stages of dental development.
The most common type of expander we use is the RPE orthodontic appliance (Rapid Palatal Expander), specifically the Hyrax expander. The RPE orthodontic appliance works by gradually widening the upper palate to correct alignment issues and create space for the permanent teeth to emerge properly.
An orthodontic expander is particularly valuable for kids orthodontist treatments, especially for children between the ages of 7 and 12. During this phase of dental development, a child’s bones are still growing, making it easier to guide the jaw into proper alignment. By using an expander at this age, we can avoid more invasive treatments in the future, such as tooth extractions or more extensive braces.
The process of using an orthodontic expander is simple. The device is attached to the upper molars with bands and is adjusted regularly (typically once a day) using a small key. The goal is to gradually widen the roof of the mouth, which can take several weeks to months, depending on your child’s needs.
While adjustments may cause slight pressure or discomfort, they are generally painless and typically subside quickly. Our kids orthodontist team at Twin Smiles Orthodontics in Palo Alto will provide detailed instructions and check-ups throughout the process to ensure everything is progressing as expected.
An orthodontic expander is usually recommended when a child’s upper jaw is too narrow or when their teeth are overcrowded. Here are some specific situations in which an expander might be the right choice:
If your child has any of these conditions, their kids orthodontist will likely suggest an orthodontic expander as part of their treatment plan.
While kids braces and an orthodontic expander both help with misalignment, they serve different purposes. Kids braces focus on aligning the teeth and correcting bite issues, while an expander primarily works to widen the upper jaw. In many cases, an orthodontic expander is used first to create space for the teeth before moving on to kids braces for final alignment.
For example, if your child’s teeth are crowded due to a narrow jaw, the orthodontic expander will first widen the upper jaw, creating enough space for the teeth to align properly. Once there’s sufficient space, kids braces can be used to straighten the teeth and correct any bite problems.
The treatment time for an orthodontic expander varies, but typically the expansion phase lasts between 3 to 6 months, with periodic adjustments during this time. After the expansion is complete, the expander will remain in place for a few more months to stabilize the jaw. Once this phase is over, your child may transition to kids braces or another treatment as recommended by your orthodontist.
After the expansion is complete, we’ll remove the expander, but your child may need to wear a retainer to maintain the results. Proper care and maintenance are crucial to ensuring the expansion lasts. Be sure to follow your kids orthodontist’s aftercare instructions carefully.
