No! All 4 wisdom teeth do not always come in at the same time, but they will always be the last set of teeth to come in. As a general rule of thumb, lower teeth usually erupts before upper teeth and teeth in both jaws erupt in pairs one on the right and one on the left. It is most common for the bottom row to erupt before the top. It is also not unheard of for the top to erupt first and it is also possible for one set to come in while the other doesn’t. Several factors can influence the permanent tooth eruption pattern such as Heredity, how they are growing and the condition of the tooth and size of the jaw.
