Is there a good tooth "paint"?

Other options may include the following:  Option #1:  Tooth bonding.  This technique works well to whiten your teeth in just one appointment, but needs to be redone every 12-18 months, because they tend to stain faster your normal teeth.Option #2:  Veneers.  You can choose your shade of white and they are extremely stain resistant.  They will last about 20-30 years, if proper dental hygiene is maintained.  Good luck and I hope this helps.

In a nutshell...."no".  If you've bleached and rebleached, and still want your teeth whiter, then you should speak with a cosmetic dentist about your veneering options, either direct composite veneers or porcelain laminate veneers.  Then you can control and choose the color you want.
