A dentist for McKinney families, on Custer Road in Frisco.

McKinney has grown by about a fifth since 2020 — from roughly 195,000 people to around 236,000. That figure is the reason this page exists: a great many people reading it moved here recently, have not found a dentist yet, and are starting from the beginning here — not switching from somewhere else.

It is also a young city. Around a quarter of McKinney is under eighteen, against about one in ten over sixty-five. In practice that means the appointment most households here are trying to book is a family one — a child's first visit, a teenager who needs a mouthguard before the season, two or three people seen in the same trip, saving three separate afternoons.

And more than a quarter of households in McKinney speak a language other than English at home. That is not a detail we mention for the sake of it — it is why eight languages are spoken across our team, and why the person explaining a treatment plan to your parent can often do it in the language your parent thinks in.
