This young man came to our office in serious pain. It was finals season at his high school, so he was under pressure. He was also malnourished and chain smoking--a lethal trio! He had Acute Necrotizing Ulcerative Periodontitis, a severe type of gum disease brought on by a weak immune system and stress. After completing a full-mouth scaling and root planing you can see that even one week later his tissue are so much healthier. His pain was gone and he even passed his final exams!
