When disc brakes for high performance cars arrived on the scene we began to hear of warped brake discs on road going cars, with the same analyses and diagnoses. Typically, the discs are resurfaced to cure the problem and, equally typically, after a relatively short time the roughness or vibration comes back.
As a result, the cheek teeth, like the incisors, have evolved to continuously grow throughout life. In other rodents, the diet of tubers, seeds, and grain requires little chewing, resulting in little wear of the cheek teeth.
Most adults will get 32 permanent teeth in all : 8 incisors, 4 canines, 8 premolars (biscuspids) and 12 molars. The last set of 4, the tertiary molars, are called wisdom teethâ¦, and they are often removed because of various problems. Some individuals will have fewer teeth, but they are usually missing molars.
