Keep having constant dreams over a period of time about teeth falling out..?

I've had the same recurring dream since i was a teenager, I'm now in my late 20s. I've always read about this and these dreams are said to be linked to insecurity. I must point out though, I've always been consciuos about my my teeth. Even now that i have veneers (porcelain teeth) and they look great, I still have these dreams, but now i dream my veneers fall off.
