I've had a try of the Prai Golden Caviar, with the Prai serum underneath and then Decleor oil. Apart from the fact that my face ended up feeling like an oil-slick before it all rolled off, I had this strange sensation with my teeth. It's hard to explain, but it feels as though I'd been chewing on metal foil or something similar - my teeth were all 'on edge'. I wasn't sure what was causing this but I tried the Caviar Gold again and it produced exactly the same result. No other products I have do this, so has anyone else had this sort of sensation from it? I have a gold filling and a metal bridge on my teeth - could there be some sort of reaction with that?
