Root-canal treatments are among the most difficult procedures in dentistry. This often leads to a failure of the treatment and a reinfection of the tooth. Lumendo is developing a light-activated, easy-to-use root canal filling material, which can make the treatment faster and easier and improve the treatment outcome, thus helping people to keep their natural teeth longer.
