So what do you think of when someone mentions metal in your mouth? Headgear? Braces? Or a toothbrush? This is about the latter.
The TiFinity toothbrush uses titanium bristles to clean your teeth and last for an extremely long time. This toothbrush has a lifespan of 2 years! So what do you pay for a toothbrush that lasts for 2 years? $50. Sounds expensive, and it might be depending on how much you spend on nylon toothbrushes every year. One really cool feature (which is partially why it lasts for 2 years) is that it is impermeable by water, so there isn’t that immense ammount of bacteria that you are/aren’t used to. –Nik Gomez
