Why Should My Child Get a Palatal Expander?
Choosing a palatal expander can significantly improve oral health and overall well-being. For starters, it addresses issues of overcrowding, which can lead to misaligned teeth and potential oral health problems in the future. By creating more space, it facilitates proper alignment, setting the foundation for a healthier smile.
Additionally, a palatal expander can correct crossbites, which, if left untreated, might cause jaw pain and uneven tooth wear. By expanding the upper jaw, palate expansion can also improve breathing by opening up the nasal passages, which is particularly beneficial for children who experience sleep apnea or chronic mouth breathing.

The Benefits Of Palatal Expanders
Corrects Crossbites
A palatal expander effectively addresses crossbites by widening the upper jaw, ensuring proper alignment between the upper and lower teeth. This not only improves oral function but also enhances the overall aesthetic of your smile.
Prevents Overcrowding
By creating additional space in the mouth, a palatal expander prevents overcrowding, paving the way for straighter teeth and reducing the likelihood of needing more invasive orthodontic treatments and surgeries later on.
Improves Breathing
The expansion of the upper jaw can lead to better airflow through the nasal passages, improving breathing patterns. This can be particularly beneficial for children with sleep-related breathing issues, contributing to better sleep quality and overall health.
The Palatal Expander Treatment Process

The journey begins with a comprehensive consultation at San Marino Orthodontics, where Dr. Siu or Dr. Chee will conduct a thorough examination of your child's oral structure. This includes taking X-rays and dental impressions to assess the need for a palatal expander. During this visit, they will discuss the treatment plan, address any concerns, and provide detailed information on what to expect throughout the process.

Fitting the Expander
Once the decision to proceed with a palatal expander is made, a custom appliance is crafted to fit your child's mouth perfectly. During the fitting appointment, the expander is carefully placed and adjusted to ensure comfort and effectiveness. Instructions on how to activate the expander, typically involving turning a small key, will be provided. This step is crucial for gradually widening the palate over the treatment period.
