Through the process of evolution, humans are gradually losing their wisdom teeth. However, evolution takes time and doesn’t happen overnight. Meanwhile, most people are still born with at least one wisdom tooth. Due to the limited space in our smaller jaws, these teeth can cause problems when they start to grow. Common problems include overcrowding in the jaw and infections, which can be extremely painful. When the pain becomes too much to bear, a visit to the dentist becomes unavoidable.
透過演化的過程，人類正逐漸失去智齒。然而，演化需要時間，並非一朝一夕的事。與此同時，大多數人仍天生會有至少一顆智齒。由於我們較小的上下顎空間有限，這些牙齒在長出時可能會引發問題。常見的問題包括顎部過度擁擠和感染，這些情況可能會令人疼痛不已。當疼痛感變得難以忍受，就會不得不去看牙醫。
