A new study has revealed that people rate their own smile more highly than their cosmetic dentist, with under-50s being particularly satisfied with their smiles.
Researchers asked 78 patients to rate their own smiles on a scale of one to 100, and then asked their dentists to rate their patients' smiles.
The findings, which are published in the Journal of the American Dental Association, indicate that people are more satisfied with their own smiles than dentists.
While the average patient gave themselves a score of 59.1, dentists' ratings averaged at just 38.6.
When photographs of the patients' smiles were shown to an independent periodontist, the average smile rating was 40.7.
The researchers said: "The fact that the patients had much higher opinions of their smiles than we dentists did is interesting.
"Dentists should be aware that patients who seek aesthetic services may have different perceptions of their smiles than patients who do not express such desires."
