What an expander does
The upper jaw grows in two halves that fuse in the mid-to-late teens. Before fusion, a fixed expander can gently and progressively widen the palate, correcting crossbites, creating space for crowded adult teeth, and often improving nasal breathing room. It's growth guidance rather than force: timed right, the body does most of the work.
What to expect
- The expander is fitted to the upper back teeth and sits in the roof of the mouth
- A tiny key turn (we teach parents) activates it on the schedule Dr Anand sets
- Pressure is felt for a day or so after turns; speech and eating adapt within days
- A gap often appears between the front teeth, a good sign the suture is responding; it closes naturally or with later alignment
- Active expansion takes weeks; the expander then stays in place for some months while new bone stabilises
Expansion works best while the jaw is still growing, one more reason an early assessment around age 7–8 pays off.
