Like A Pencil Eraser For Tooth Stains!

 Before After

Now, the very same tooth stain removing rubber polishing tips that dentists have used successfully for more than 40 years are available for at-home and on-the-go use. Tooth Stain Eraser features ultra-fine white aluminum oxide particles in its flexible rubber tips which safely removes stains from tooth surfaces commonly caused by tobacco, coffee, red wine and cola. 


Point shape for between teeth  Bullet shape for flat surfaces 

Using light pressure and an erasing action rub tip on stained areas. Surface stains should come off easily.

Discard erasers before cleaning tips wear to metal posts.
Internal stains cannot be erased. See your dentist. 



The primary objective of this laboratory study was to evaluate the potential of using theSTAINO® Tooth Stain Eraser product to effectively remove stain from natural tooth enamel.
The secondary objective of this study was to evaluate the abrasivity of the product relating to scratching or other deleterious effects on tooth enamel. 


Stain Removal

On light coffee, tea, or tobacco stain.

Visual examination and Colorimetric determinations showed that regardless of the type of stain, removal of the stain from the extracted teeth was generally accomplished after 30 hand strokes with the 400 grit STAINO® Tooth Stain Remover product.

On heavy tobacco stain with calculus.

In general, for total stain removal using the 400 grit STAINO® Tooth Stain Remover 200 strokes were required. It should be noted that very heavy stains were generally associated with calculus build-up on the teeth. The degree of difficulty of removal of the stain was compounded by the removal of the underlying calculus.

Photographs of the stain removal of some heavily stained lower incisors are shown in figures 1-4.

Using the stereomicroscope, it was observed that the enamel surface rubbed with the 400 grit Tooth Stain Eraser had no visible scratches, and remained shiny in appearance.

Using the scanning electron microscope at 400 to 1000X, it was determined that the 400 grit STAINO® instrument created scratches which were generally less than 5 microns in with. See Figure 5.

1. The 400 grit STAINO® Tooth Stain Eraser is capable of removing light and heavy stains of coffee, tea, and tobacco.

2. The 400 grit STAINO® Tooth Stain Eraser creates no visible differences in the enamel surface after rubbing, and the surface remains shiny. Microscopically, it appears that this instrument creates scratches in the enamel surface which are less than 5 microns in width. In the investigator’s opinion these small scratches created may be remineralized by natural salivary constituents and by using remineralizing over-thecounter toothpaste formulation.
