Dr Jibreel Oysul, a consultant dental surgeon with Meenakshi Mission Hospital and Research Center, Madurai, Tamil Nadu has extracted, processed and collected 10,000 non-carious human natural teeth since January 2011. He started collecting the teeth for study and research purposes. The collected teeth have gone through 3 stages of sterilization. After he started collecting, he realised that people were losing good teeth because of poor gum maintenance. Dr Oysul started campaigning towards proper oral health and gum maintenance, conducting free dental camps every Wednesday.
