(CNN) -- If you think an electric toothbrush is high-tech, wait until you hear about the Internet-enabled version.
Jesse Schell, a game designer and Carnegie Mellon University professor, says toothbrushes will be hooked-up with Wi-Fi Internet connections within five years.
The point? If the entire Internet knows how often you brush your teeth and for how long, there's an incentive to brush more often.
Toothbrush makers could offer rewards for frequent brushers, too. Say you brush your teeth twice each day for three months. A company like Crest or Procter & Gamble could reward you with coupons for more toothbrushes, since your well-used bristles would probably be frayed by then.
