In treatment room 1 of his practice, dentist Dr. Dietmar Oesterreich (Vice President of the Federal Dental Association in Germany) welcomes a new patient.
Sylvia M.* neither complains of toothache nor has she come for a routine check-up. “I want my teeth to be as white as they used to be,” she says, pointing to her discoloured teeth. She suspects her intense coffee enjoyment. The two upper middle incisors appear particularly dark. A detailed examination of the findings does indeed reveal the presence of dyes, but the discoloration of the two incisors has another cause. An x-ray brings it to light, and the 30-year-old patient remembers: “Since I was 16, the incisors have been treated at the root”. Over the years, the root canal filling has made the teeth look darker and darker. Dr. Oesterreich also points out the dark plastic fillings in the lateral, upper incisors. “Fillings do not change due to whitening, we have to replace them afterwards.”
