Broadway star Marissa Jaret Winokur (“Hairspray”) has joined the cast of “Retired at 35” (9 p.m., TV Land), now entering its second season. For the uninitiated, “Retired” follows the travails of a New York City burnout, David (Johnathan McClain), who decides to “retire” to Florida. This upends the plans of his harried parents (George Segal and Jessica Walter), who were about to embark on their “golden years.”

Winokur plays David’s sister, Amy, who competes with him for their parents’ time, attention and affection. If shows were judged by casting alone, “Retired” would be a hit. Unfortunately, contrived situations and obvious dialogue can scuttle a series with even the best talent.

• Does America have a dental crisis? “Frontline” (9 p.m., PBS) examines the enormous social and financial costs arising from the poor-to-nonexistent dental care available to millions of Americans who are poor or barely getting by.

”Dollars and Dentists” shows how many people forgo dental care entirely, leading to serious health problems and surgery that can lead to bankruptcy. Medicaid has also been burdened by excessive costs for surgeries, often performed in emergency rooms, which could have been prevented with regular checkups and dental care. Even poor families who are entitled to dental benefits often have trouble finding a dentist who will treat them.
