SmileDirectClub falls in U.S. market debut

A toothache for the online startup that wants to give you straighter teeth.

SmileDirectClub made its stock market dubut Thursday opening on the Nasdaq at $20.55, 11 percent below its $23 IPO price.

A disappointing debut after recent blockbuster IPOs have stumbled, with companies like Uber and Slack getting pummeled by skeptical investors.

The Nashville-based SmileDirectClub sells teeth aligners - an alternative to traditional braces - directly to consumers on its website.

While its losses are growing, the dentistry upstart's revenue has jumped sharply over the past couple years.

But investors seemed to focus on the losses.

A sobering response at a time when other money losing companies like WeWork and Postmates are also planning to go public.
