The survivor, Kyleigh Scott, is Dr. Wilstead's patient who came for a wisdom tooth extraction.
Scott had been headbutted by a former partner two years ago, leading to a damaged front tooth.
She also said she was waiting until she received her tax returns to fix all of her teeth. However, Dr. Wilstead decided to fix her tooth for free of charge.
The grateful Scott teared up as she thanked the dentist profusely.
In his Facebook post, Dr. Wilstead said that this was a "moment I will cherish forever."
