A Las Vegas family has filed a lawsuit against a dentist they accuse of setting their 5-year-old daughter’s mouth on fire during a routine procedure last year. The lawsuit, filed last week against Just for Kids Dentistry & Orthodontics owner Dr. Karan Dhillon, seeks more than $15,000 in damages. The lawsuit alleges the girl’s parents took her to Dhillon’s practice to have several crowns put on her teeth. During the girl’s procedure, a tool called a diamond bur emitted a spark that “caused the throat pack in (the girl’s) mouth to ignite and produce a fire” that lasted a couple of seconds. The girl was rushed to the hospital, where she remained for four days as she was treated for burns to the inside of her mouth. The lawsuit states that some of the girls’ injuries “may be permanent”.
