Is toothbrushing behaviour habitual? Cues, context, motivators and patient narratives

Abstract

Objectives Toothbrushing is generally considered as a key self‐care behaviour necessary for maintaining good oral health. Although twice‐daily brushing is widely recommended as beneficial since this provides both biofilm removal and a regular application of fluoride, some people such as those with low socio‐economic (SES) backgrounds often brush less regularly. Habit theory identifies that behaviours become habitual when they are undertaken repeatedly in response to a particular cue within a stable context. Once behaviour becomes automatic, long‐term maintenance is more likely even if motivation wanes. Establishing toothbrushing as a habitual behaviour is therefore an intervention strategy which may help reduce health inequalities. Therefore, the objective was to more fully understand the nature of toothbrushing behaviour in adults and what prompts its instigation and execution in the morning and evening, in order to inform the design of interventions in this area. Methods Twenty‐nine semi‐structured interviews were undertaken in an urgent dental care centre in a deprived area of North West England. Thematic analysis using a framework method was used to code the data into theoretically derived categories. Results Morning toothbrushing was found to be strongly integrated into cleansing routines and was identified as a behaviour predominantly initiated in response to visual cues. Some toothbrushing behaviour was prompted by internal cues, expressed as strong feelings or urges. These were more related to night‐time toothbrushing habits. Common morning motivators were aesthetics and social acceptability. Evening motivators were relatively idiosyncratic. Cleaning of the mouth following a hard, manual working day emerged as a strong driver for low SES males. Conclusion Understanding the nature of habitual morning and evening toothbrushing is important for the design of effective behavioural interventions, especially those aiming to achieve sustainable improvement in the frequency of night‐time toothbrushing.

Early childhood caries prevalence and associated factors among preschoolers aged 3–5 years in Xiangyun, China: A cross-sectional study

“…Regular toothbrushing with a fluoridated paste is generally considered a fundamental self-care behavior for preventing caries and maintaining oral health ( 30 , 31 ). According to a systematic review, children brushing their teeth less frequently have an increased risk of developing new carious lesions than those brushing more frequently, which was more pronounced in primary than permanent dentition ( 32 ).…”

Oral health behaviors for young low-income urban children during the COVID-19 pandemic: a mixed methods analysis

“…Our ndings emphasize previously described social and programmatic structures that support consistent brushing behaviors. While it is well known that daily routines are critical for maintaining behaviors such as brushing, 19,21 our results highlight the importance of social presentability and accountability as motivators for establishing those routines. During interviews, parents explained that when children did not have to be anywhere, brushing routines changed.…”

Evaluation of the Effects of Mouthwash on the Morphology and Cell Viability of Osteoblast-Like Cells

“…Chemical plaque control is the most commonly recommended means of oral hygiene after periodontal surgery [6]. However, mouthwashes should not be considered a substitute for daily brushing and flossing [16,17]. Swallowing or ingesting mouthwash should be avoided whenever possible [18] and can cause vomiting, nausea, or intoxication [19].…”
