Brian “Baby” Williams, more commonly known by the alias “Birdman,” is perhaps as famous for his grill -- slang for gold jewelry worn over the teeth -- as he is for his rhymes. The music mogul's flashy teeth consist of white gold-plated, diamond encrusted crowns said to have cost $500,000. Birdman's grill is permanently affixed to his teeth, so if you have one like his, you'll have to use cleaning methods that are white-gold friendly and safe to ingest.
Create a “slurry,” or medium-density paste, with baking soda and water. Baking soda is nonabrasive and gentle, so it won't tarnish or scratch white gold or diamonds.
Add a nickel-sized dollop of the baking soda slurry to a soft-bristled toothbrush. Use an extra-soft toothbrush if possible.
Brush the inside, outside and chewing surface of your grill with the brush tilted at a 45-degree angle. Use short, back-and-forth strokes.
Rinse your mouth thoroughly with warm water. Don't use salt water as salt may tarnish white gold over time.
Floss your grill. Wrap 18 inches of floss around your two middle fingers, contour 1 to 2 inches of taut floss between your gold-plated teeth and make a short, back-and-forth motion. Do so between all the teeth in your grill. Use a wax-free, vegan floss to avoid exposing your grill to waxy buildup or scratches.
Repeat this process after every meal, in the morning and before going to bed at night.
