Lil Wayne and Yung Berg have reportedly failed to appear in a New York court today (August 14) for hearings relating to gun charges.

According to TMZ, Wayne's camp claims that the New Orleans bred rapper failed to show because of a dental condition that restricts him from driving.  A reason for Berg's no-show was not given.

Wayne's gun charges from a 2007 arrest.  A .40 caliber handgun was found by authorities in his tour bus last July following a performance with Ja Rule at Manhattan’s Beacon Theatre.

Wayne, who has pleaded not guilty to the weapons possession charges, faces to three and a half years in prison if convicted.

Berg's gun charges stem from an arrest this past weekend.  He also faces charges of marijuana possession and menacing.
