It promised a set of gleaming white, perfectly straight gnashers without the need for costly and painful dentist appointments.
Wow. As someone with a set of "British" teeth - i.e. slightly crooked and less than blindingly white - I was intrigued.
Now, obviously, I did not click on the ad's link. I am not that stupid. However, I did consult Professor Google to find out more. It seems that you can purchase these wondrous plastic dentures online, for a ridiculously low cost. You soak them in hot water to soften them up then click them over your existing teeth. As they cool they sort of adhere to your teeth and form an aesthetically pleasing veneer.
I am not entirely sure if you can eat with these magic teeth or how easy if is to pry them loose, but the videos seem to suggest that we can all look like Hollywood stars with lots of gleaming pearly smiles.
Or we could just continue with whatever nature has given us and still be able to chew our rusks.
