Johnny Dang hooked up with Paul Wall to become Johnny the Jeweler, an only in Houston tale of a Vietnamese immigrant made good.  As Eyder Peralta tells it:

Seeing the market for a jewelry repair shop, he set up shop weekdays in a flea market selling $30 name plates and cut-rate high school graduation rings. Weekends he set up a table on campus, repairing jewelry. Soon he’d made enough to rent a space at the mall.

Meanwhile, Paul Wall was working the streets, selling mix tapes. He was heading promotion teams for national labels and his local fame grew under the shadow of the legendary DJ Screw. It was by chance that he stopped at Dang’s store one day in 1998.

As I understand it, Paul Wall built his grill biz on Dang’s expertise but already knew a lot about the business of teeth.  Peralta continues:

Dang fashioned Lil Jon’s $60,000 fang grille, and bottom grilles for Chicago rapper Kanye West. And he’s made, at $30,000 a pop, a good share of the diamond pendants worn by Swisha House record label artists.

Once a one-man operation working from his garage and a flea market booth, Dang is now riding high with a celebrity clientele and 45 employees.

An interview with Paul Wall about the grill biz last spring seemed a little confused by the name of Dang’s shop, TV Jewelry, but does communicate the sense in which Paul Wall has connected the hip hop scene with Dang and helped create Johnny the Jeweler.
