Bad taste under new porcelain veneers?

I recently had 10 porcelain veneers placed on my top teeth about three weeks ago. For the past week or two I've had a bad taste coming from the front left eye tooth area of the veneers. I'm brushing 3 x a day and flossing twice a day with a mouthwash routine. This isn't an issue of cleanliness. I also don't believe my teeth all the sudden started rotting once the veneers were placed but all I taste is rot and almost as if I can suck it out of the tooth as I let saliva build in my mouth.
