Titanium Toothpick

No, there is no danger to your teeth from metal utensils because they are softer than enamel. They cannot scratch your teeth in simple use, they're not hard enough. Titanium, on the other hand, is HARDER than enamel. It always scratches your teeth, the same way a diamond abraided against glass always leaves a scratch. The scratch on your tooth is just too fine for you to see, but scratches accumulate. On the mohs scale of hardness, tooth enamel rates a 5. Common steel is 4.5, slightly softer than enamel. Stainless steel is a 5, same hardness as enamel. Like hardness doesn't usually scratch. Titanium is a 6. Harder than enamel. Scratches your tooth. The titanium nitride used in jewelry and probably the toothpick is a 9. Almost as hard as a diamond at 10. Much harder than tooth enamel, and therefore almost certain to scratch it when sharp. So no, you really should avoid using a titanium toothpick on your actual teeth whenever an alternative exists. You are scratching up your tooth enamel.

I think they may be made to scrape the plaque off of titanium rods. I haven't found a toothbrush that can fit between the rods so the plaque builds up eventually. I've been warned not to use anything but my fingernails to scrape the rods myself. I haven't seen the product, so I may be completely wrong. But if that what it's for, I would LOVE to buy one, of it's affordable. It would save me money in the long run. Those office visits for cleaning aren't cheap. At least not those of us who live on a fixed income.

For a second I felt bad for whoever else was getting pinged as this chain of comments waxes poetic, but it's good to see this is just an intimate moment for us to chew the fat. In that vein of thought, perhaps one day they will mount a plaque in your honor for really sticking the landing on these puns. Cheers :D
