Same feeling here. Dental seems particularly fraught (though maybe I just pay more attention to it out of interest). I know the cycle time between press releases/hype and actual application can be the better part of a decade, so I assume that's coloring my perception too.
re: dental in particular - It seems like enamel regeneration and stem-cell-based tooth replacement have both been in the news year-after-year without applications actually coming to market.
