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

Plano is the outlier among the cities we serve, and it is the most useful thing to know about it. While Collin County has been filling up, Plano has grown by under three per cent since 2020 — roughly 285,000 people to 293,000. It is not a city being built; it is a city that was built.

The age profile follows. Nearly fifteen per cent of Plano is sixty-five or over, the highest share of any community on this list, and just under a fifth is under eighteen, the lowest. Dentally that matters more than it sounds: gum disease prevalence climbs steadily with age, and the fillings and crowns placed in the 1990s and 2000s are now reaching the end of what they were built for.

Plano is also the most multilingual city we serve — thirty-eight per cent of households speak a language other than English at home, and nearly three in ten residents were born outside the United States. Eight languages are spoken across our team, and nowhere is that more load-bearing than in a conversation about gum surgery.
