Since my reactions will be different than other people's, please do not go by my reactions. But after 4 hours, I noticed I was getting a headache, slight swelling in my mouth and touge and a sence of something not right. I tool it out, all reactions went away. I waited till the next day and tried again and same thing happend again. I did however like the feel of the material as it was hard and smooth.

So that is why it is very important that you do a cheek and gum test. Because once they put it in your mouth, it is hell and I mean hell getting it out along with having the reactions.

Something else to remember is that there is a chance that once you do get a reaction to something that it builds on itself to the point where you are not able to fuction normally. With my 1st situation of the aries and zirconium crowns, the reaction kept getting worse and worse each day and drugs where not stopping it. I know I am more sensitive than most out there so I can feel things right away usually. But if you notice any sort of reactions, just keep in mind that it can get a lot worse over time. Time is the question as it may take years or a matter of hours. But you have to be very aware of how you feel before you test materials in your mouth.
