Toothbrushing and erosive tooth wear
Erosive tooth wear, also called dental erosion, defines the loss of dental hard tissue (enamel and dentin) caused by acids from food and beverages or from gastric reflux. Tooth wear can also be caused by tooth-to-tooth contact (attrition) or by friction (abrasion), for example from toothbrushing.
Question
What scientific studies or systematic reviews are there on delayed toothbrushing after intake of acidic food and beverage compared to immediate toothbrushing?
Identified literature
No relevant systematic review based on clinical prospective studies were identified. One case control study was identified that investigated the association between timing of dietary acid intake and erosive tooth wear [1].
One systematic review on enamel wear was identified and it summarized in vitro and in situ studies comparing human enamel brushed at different time points after an acid challenge (Table 1) [2]. In addition to the six relevant studies [3-8] included in the systematic review, one relevant in vitro study not included in the systematic review was also identified [9]. The primary studies were not assessed for risk of bias and therefore the results are not presented here.

Included studies | Population/Intervention | Outcome and Results |
Hong et al, 2020, [2] Does delayed toothbrushing after the consumption of erosive foodstuffs or beverages decrease erosive tooth wear? A systematic review and meta-analysis |
||
6 relevant studies on human enamel (3 in situ, 3 in vitro) | Population: Blocks of human enamel exposed to acid challenge (demineralization) Intervention: Storage in saliva or in the mouth before acid exposure, and before toothbrushing (10 to 120 minutes) Control: Toothbrushing immediately after acid exposure |
Erosive toothwear Profilometer or indentation measurements Storage in saliva 30 to 60 minutes (5 studies): SMD −0.15 (95% CI, −0.54 to 0.24) Not significant |
Authors' conclusion: “Delayed toothbrushing after an erosive attack was not effective at decreasing the ETW of human enamel compared to immediate toothbrushing […].”…..”Moreover, since the present findings were based on in vitro and in situ studies, the results must be interpreted with caution. Further randomized controlled clinical trials are necessary to confirm the present findings.” |
