 `What is the bite power of the human teeth?`
 ```Hello abartgirl53! "The biting force value of normal teeth of 770 human subjects were measured by electric resistance strain gnathodynamometer. 365 were males, and 405 females. Their ages ranged from 13 to 49. The results showed that the biting force value of males is larger than that of the females (P < 0.01). In the males, the biting force value of those aged 13-16 gradually increased with age, and the maximal biting force values of incisor, bicuspid, and first molar of all the males were 43.3kg, 99.11kg, and 120.66kg respectively." PubMed - indexed for MEDLINE http://www.ncbi.nlm.nih.gov/entrez/query.fcgi?cmd=Retrieve&db=PubMed&list_uids=7744385&dopt=Abstract "Normal chewing places about 68 lbs/sq inch of pressure on the back teeth. If you intentionally clench your teeth you may increase that force to about 150 lbs/sq inch. However, an individual who clenches and grinds their teeth subconsciously at night can place up 1200 lbs/sq inch of force. That sounds like an industrial grinding machine!" Dental Health Directory Library Bite and Occlusion http://www.dental--health.com/biteocclusionpohl.html "The bite force was measured with the biting fork placed between the first molars and between the incisors, respectively." "The mean values were higher for the males than for the females. In the males the maximal bite force thus measured in the molar region was 39 kg (382 N) and 18 kg (176 N) in the incisor region.corresponding values for the females were 22 kg (216 N) and 11 kg (108 N)."
