Modal analysis is carried out to test the natural frequencies of certain human teeth, including central incisors (Cls), canines (CAs), first premolars (FPs) and first molars (FMs). A total number of 1007 teeth are tested, taking into account tooth type, oral location, age and gender, to analyse the effects of the above-mentioned factors on the natural frequency of the sample teeth. The results reveal that no significant difference in the natural frequency is noted among teeth in the four different intra-oral quadrants. Nevertheless, tooth type and age elicit an effect upon the value of the natural frequency of teeth. On the other hand, the mean value for the natural frequency of Cls (1.27±0.15kHz), CAs (1.30±0.15kHz), FPs (1.27±0.15kHz) and FMs (1.16±0.12kHz) for males are significantly lower (p
