Teeth, on the other hand, become the most resilient portion of the body after death, which is why they are frequently found with ancient bones. "Teeth deteriorate readily in life, but it stops when you die," adds Dr. Lazer, noting that the microorganisms that cause tooth decay cannot live after death. Teeth have a high survival rate. Even if a body is burned or buried, its teeth will remain intact. After death, the muscles relax, causing the jaw to drop open. This allows room for the teeth to move around more easily - especially important if you were wearing them when you died. Decomposed flesh and bone don't remain together after death, so teeth aren't as likely to be found with these components. However, depending on the type of death, certain organs may be more likely to be located with particular body parts. For example, stomach contents are usually found in the abdominal cavity, while brain tissue can be found near the head or inside the skull. In conclusion, teeth remain intact after death, allowing us to identify victims even if their bodies are decomposed.
