The teeth are the body part that is toughest. The anatomical and chemical makeup of teeth is quite distinctive. The scientific field of tribology examines lubrication, friction, and wear. It is desirable to assess the material qualities, chemical compositions of various materials, and tooth structure in order to comprehend the wear behaviour of human teeth. Human teeth erode quite gradually. Tooth wear is a multifactorial phenomenon that combines physical, chemical, and mechanical processes, in addition to being a complicated process. The tribological behaviour of teeth is greatly influenced and determined by the oral environment in which we live. The wear processes of artificial materials used in dentistry are rather sophisticated given the intricate biomechanics and intraoral environment. Abrasion, attrition, fretting wear, corrosion, and fatigue are some of the main wear mechanisms in our mouth cavity. Various combinations of these activities result in the slow surface deterioration of materials in the oral cavity. Excessive wear may cause early failure, necessitating the replacement of dental implants and restorations. Even though we have achieved incredible progress in the area of dental wear, there is still more research and analysis that needs to be done. This will enable us to develop a bionic design, a tribological design-based therapeutic therapy against dental wear, and a systematic correlation between the tribological behaviour and structure of human teeth. Eventually, more and more study trajectories will point us in the direction of a better treatment prognosis. So maybe these talks will shed some light and offer more information about what has previously been discovered about human teeth
