What Phase 1 costs, and how to think about the total

Phase 1 treatment at our practice typically runs $2,000–$4,500 depending on the appliances involved — a twin block with built-in expansion, an expander, Invisalign First, partial braces, a habit appliance. It's quoted in writing with its retention included, and alongside it we'll give you an honest expectation of what Phase 2 will involve and cost later.

Why we're candid about the second number

Because a family deciding on early treatment deserves the whole picture. Phase 2 — comprehensive braces or aligners in the teens — is usually still needed after Phase 1. What a well-chosen first phase changes is its character: often shorter, simpler, without extractions, and without the surgical conversation that a skeletal problem left to grow can produce. That is where the value of growth modification sits — not in avoiding Phase 2, but in making it a smaller thing.

When Phase 1 is money well spent

When there's a specific indication: a crossbite steering the jaw, a narrow arch, a lower jaw sitting back, an underbite, severe crowding, a canine off course, a habit reshaping the bite, airway red flags. In those cases the first phase does work that becomes impossible once growth ends, and the total cost over a childhood is frequently lower than a single late, complex phase — or a surgical one.

When it isn't

When a child has mild crowding and a normal jaw relationship and would reach the same result at thirteen in one phase. We'll say so, and monitor for free until the timing is right. A first phase should be able to name what it prevents; if it can't, it's a second invoice. Our payment structure for both phases is on payment plans, and insurance treatment of two phases on insurance in BC.

A worked comparison

Two nine-year-olds with the same pattern: a narrow upper jaw, a lower jaw sitting back, prominent front teeth. Child A has a twin block with built-in expansion at nine — about $3,500 — and a shorter comprehensive phase at thirteen, perhaps $5,500, non-extraction. Child B waits, has four premolars extracted at fourteen to make room, and a full comprehensive case, perhaps $7,500, with a jaw relationship that could only be camouflaged. Child A's total is higher on paper by a few hundred dollars and lower in every other currency: teeth kept, treatment simpler, and no surgical conversation later. We can't promise that outcome for every child — growth varies — but it's the outcome we're aiming for when we recommend a first phase, and it's why we don't regard the second fee as a duplication.

How the two fees are handled

Each is quoted in writing at its own time, each with retention included, each on its own payment plan. Extended-health orthodontic maximums apply across both — a first phase draws down the same lifetime amount — and we'll tell you what will be left for the second. Monitoring visits between the phases cost nothing.

The bottom line

Phase 1 is $2,000–$4,500 at our practice, retention included, quoted alongside an honest expectation of Phase 2. When it's indicated — a narrow arch, a retruded jaw, a crossbite, an underbite — it frequently lowers a childhood's total treatment by making the second phase shorter and non-extraction. When it isn't, we monitor for free. Two fees, one honest picture, both plans through our office.
