The outer layer of epithelium is called the parietal layer. Blood is filtered out from the capillaries through the visceral layer of epithelium into the capsular (Bowman's) space, and can move out from here into the proximal convoluted tubule.

The Average Lifespan of Dental Crowns. Generally, dental crowns last between five and 15 years. We've seen some crowns last even longer, up to 25 or 30 years. Because crowns should last at least five years, most insurance companies will pay if the crown needs to be replaced anytime after those first five years.
$2000 is on the higher end for a crown,but,I would assume that the materials being used are of the highest quality and the level of care is top notch..meaning....the crown should last you way longer than a cheaper crown.Sure,you can get a crown for under $800,but,I would be cautious about its quality and longevity.
