Yes, there are many products made for home use, which can be used to whiten or bleach discolored teeth and they're usually in form of gels, strips, tooth pastes, bleaching pens, chewing gums, and so on, containing specific oxidizing agents like hydrogen peroxide or carbamide peroxide. Using such at-home tooth whitening products for lightly stained teeth is usually more cost effective than in-clinic dental bleaching procedures. For heavily stained teeth, however, in-clinic dental bleaching is recommended.
