The least attractive tooth shape is generally considered to be the S-shape in maxillary incisors. This finding is consistent across studies involving dentists, dental technicians, and patients.
Studies and Findings
Several studies have explored the perception of different tooth shapes. A study published in 2016 found no significant difference in the ranking of the S-shaped maxillary incisor as the least attractive tooth shape among different groups (dentists, dental technicians, and patients) [https://discovery.ucl.ac.uk/1496188/1/Leung_201604%20Aesthetics%20paper%20.pdf]. Other research indicates that triangular tooth shapes are also rated as less attractive, particularly in female images [https://www.sciencedirect.com/science/article/abs/pii/S0300571216300653]. Conversely, tapered-ovoid incisors have been identified as the most attractive, while square-shaped maxillary incisors were frequently cited as the least appealing [https://uk.dental-tribune.com/news/tapered-ovoid-incisor-shape-is-most-attractive-in-women/?time=1511349376].
Factors Influencing Attractiveness
The attractiveness of a tooth shape is subjective and can be influenced by various factors, including:
- Overall smile aesthetics: The shape of individual teeth contributes to the overall harmony and balance of the smile.
- Individual preferences: Personal opinions and cultural background can affect perceptions of beauty.
- Symmetry and proportion: Symmetrical and well-proportioned teeth are generally considered more aesthetically pleasing.
It's important to note that while certain shapes are statistically rated lower in attractiveness, individual preferences can vary significantly. A seemingly "unattractive" shape might still look aesthetically pleasing within the context of a person's unique facial features and overall smile.
