What Happens If You Leave a Single Missing Tooth Unreplaced? Setting Out the Evidence on Drifting, Cleaning and Chewing｜證據鏈

Whether to replace a tooth after losing it cannot be settled by the line "the other teeth are bound to fall over". What the existing systematic evidence can better support is this: when posterior occluding pairs are clearly reduced, overall masticatory performance may become worse. Most studies of this kind, however, observe shortened dental arch — that is, several posterior teeth or several occluding pairs missing — which is not a synonym for an adult who has lost a single tooth. At present this corpus contains no direct systematic review showing that the loss of a single permanent tooth in an adult causes adjacent teeth to drift or creates areas that cannot be cleaned; data on the early loss of primary teeth in children cannot be extrapolated to adults. Nor do the existing reviews support treating one or more missing teeth as a settled cause of temporomandibular disorder — in other words, it cannot be written as "missing teeth inevitably lead to TMD".

FAQ

If I lose one tooth, will the tooth next to it certainly fall over?
At present this corpus contains no direct systematic review on the drifting of adjacent teeth after an adult loses a single permanent tooth. The review of early primary tooth loss in children supports space maintenance, but growth, eruption and the adult situation are different, so it cannot be extrapolated directly [F4].
歯を一本失ったら、隣の歯は必ず倒れてきますか？ — 現時点でこの資料群には、成人が永久歯を一本失ったあとの隣在歯の移動に関する直接のシステマティックレビューはありません。小児の乳歯早期喪失のレビューは保隙を支持していますが、成長、萌出、成人の状況は異なるため、そのまま外挿することはできません [F4]。
