Your teeth are one of the few things meant to last eighty-plus years, yet national data shows only about two-thirds of U.S. adults saw a dentist in the past year. Prevention is consistently the least expensive path to a healthy mouth waiting until something hurts almost always costs more, in both money and tooth structure, than catching it early. Three habits make the biggest difference: keep two cleanings a year, replace your toothbrush every three months, and don't skip a checkup just because nothing hurts, early problems are painless by design. Treat your smile like the long-term asset it actually is.
