The reason is, when the lower back molar tooth is lost, the teeth next to it can tip over into the space left by the missing tooth. In addition, it is very common for the upper opposing tooth to overgrow and once this happens there is no way of pushing that tooth back into its correct position and it usually needs to be removed.
Over time, other problems such as increased spacing between front teeth, abnormal bite characteristics, increased incidence of gum disease, increased decay, increased stresses on remaining teeth, headaches and jaw joint problems usually all occur. |
