You mean like this? So do I bite before the silicone is injected or after? Because what I did was the silicone was injected into one ear with my mouth closed then after awhile, I was told to open. Then after that, I had to close my mouth again for the other side, then injected into the other ear, then mouth opened for about 5-10mins. Then close the mouth.
No, not like that. Take a look at this video, you should get what I meant. I'm at a lost of words to explain this for some reason.
