A proposed class-action lawsuit filed in Minnesota federal court against Minneapolis-based 3M Co. claims that the company’s Lava Ultimate dental crowns contain defects that cause the crowns to de-bond inside patients’ mouths. The filing by Burns Charest on behalf of dentists in Georgia and Texas is seeking certification as a nationwide class seeking damages and other relief since dentists have been forced to cover the cost of replacing the crowns. “This suit involves hundreds of thousands of 3M Lava Ultimate restorations performed in dental practices throughout the country,” says Burns Charest lead partner Warren T. Burns. “Every day, dentists are replacing Lava Ultimate crowns at great expense to their practices and reputations – all because 3M put a faulty product on the market.”
