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

Allen has grown by about eight per cent since 2020, from roughly 104,600 people to 113,400. Alongside Celina at nearly four times its size and Prosper at half again, that makes Allen one of the settled communities here — a city adding households at the edges of what is already built.

Its age profile sits between the extremes: a quarter under eighteen, eleven per cent over sixty-five, and about seven in ten homes owner-occupied. Nearly a third of households speak a language other than English at home.

The dentistry that follows a city like this is unglamorous and it is most of what actually gets done. Households that have been in the same houses for fifteen or twenty years have fillings and crowns of about the same age, and restorations do not last forever. They fail at the margin, quietly, and usually with no pain until late.
