What Types of Teeth Whitening Are There? How Air Polishing, Light-Assisted Whitening and At-Home Whitening Work — and the Different Problems They Address｜證據鏈

In the dental surgery, the term ‘teeth whitening’ actually refers to two things with entirely different mechanisms: The first is removing material attached to the tooth surface. Tea stains, coffee stains and tobacco stains are forms of extrinsic stain: material deposited on the tooth surface. Air polishing belongs to this category — the literature classifies it as a cleaning instrument used to remove soft deposits and stains. It addresses ‘material that has become attached’, not the colour of the tooth itself. The second is using peroxides to change the colour of the tooth itself. Light-assisted whitening (in-office whitening) and at-home whitening both belong to this category. They use hydrogen peroxide or carbamide peroxide, which acts within the tooth structure. These two approaches cannot replace one another, nor should they be compared as though they were the same thing. If tea and coffee stains are the problem, a cleaning procedure is the appropriate direction; if the tooth itself looks yellow, a bleaching procedure is required. For bleaching, the literature contains three fairly consistent findings that differ somewhat from common marketing claims:

Per that revised version: (1) the statistics are corrected from p = 0.95 / 0.85 to p = 0.76 (colour change) and p = 0.65 (the intensity of post-treatment sensitivity); (2) a new statement is added that the risk of sensitivity is higher with in-office bleaching (p = 0.09); (3) the conclusion is corrected to state that light activation did not increase the intensity but did increase the risk of sensitivity. All three points have been applied to this card. ⚠️ The PubMed abstract still shows the uncorrected version, so looking the paper up on PubMed will show the old figures)（https://pubmed.ncbi.nlm.nih.gov/38371984/）

FAQ

Does air polishing count as whitening?
No. The literature classifies air polishing as a **cleaning instrument** — in its section on clinical implications, a systematic review states that low-abrasion powders (erythritol and glycine) **are recommended for removing soft deposits and stains** [F1]. It addresses extrinsic deposits attached to the tooth surface, with the aim of restoring the tooth's original colour. It is peroxide bleaching that changes the colour of the tooth itself — that is the subject of another category of literature. **The two cannot replace one another.**
エアポリッシングはホワイトニングですか？ — いいえ。文献ではエアポリッシングを**清掃器具**に分類しています。あるシステマティックレビューは、臨床的意義の項で、低研磨性パウダー（エリスリトール、グリシン）が**軟性沈着物とステインの除去に推奨される**と説明しています [F1]。対処するのは歯の表面に付着した外因性沈着物であり、目的は歯を本来の色に戻すことです。 歯そのものの色を変えるのは、過酸化物による漂白処置であり、別の種類の文献が検討しているものです。**両者は互いに代替できません。**
