Summary Symmetric, aligned and luminous smiles are usually classified as ‘beautiful’ and aesthetic. However, smile perception is not strictly governed by standardised rules. Personal traits may influence the perception of non‐ideal smiles. We aimed to determine the influence of personality traits in self‐rated oral health and satisfaction and in the aesthetic preference for different strategically flawed smiles shown in photographs. Smiles with dark teeth, with uneven teeth, with lip asymmetry and dental asymmetry were ordered from 1 to 4 as a function of the degree of beauty by 548 participants, of which 50·7% were females with a mean age of 41·5 ± 17·6 years (range: 16–89 years). Self‐assessment and oral satisfaction were recorded on a Likert scale. Personality was measured by means of the Big Five Inventory ( extraversion, agreeableness, conscientiousness, neuroticism and openness ), and the Life Orientation Test was used to measure optimism and pessimism . Of the four photographs with imperfect smiles, dental asymmetry was the most highly assessed in 63% of the sample, and the worst was lip asymmetry, in 43·7% of the sample. Some personality traits (above all conscientiousness and openness ) were significantly correlated with the position assigned to the photographs with dental and lip asymmetry or with misaligned teeth. The extraversion, agreeableness and openness traits were correlated with the self‐perceptions of oral health and aesthetics of the participants. Dental asymmetry seems to be better tolerated than lip asymmetry. Personality traits are weakly but significantly correlated with the aesthetic preference and oral health values, conscientiousness and openness being the most relevant domains in this sense.
