I used to have that on occasion, but for some reason it would randomly go away. I used to brush my teeth often/hard but no longer do, maybe that's why? I also had receding gums when I did that. Now I brush them once a day and more softly and my gums are healthier, no translucent teeth, and I never have cavities. Not sure if this is the sole reason but it may be.
