Tooth wear has emerged as a notable oral health concern that can negatively impact quality of life. Although Parkinson’s disease (PD) is associated with poorer oral health compared to healthy populations, research specifically addressing tooth wear in PD remains scarce. Data on its prevalence and contributing factors in this group are particularly limited. This review examines the existing evidence on tooth wear in PD, highlighting reported prevalence, potential risk factors, and avenues for future investigation. A search of PubMed yielded four relevant studies, comprising one case report and three surveys. These studies indicate that PD patients may experience more pronounced tooth wear than healthy individuals. Additionally, connections between tooth wear and factors such as bruxism, temporomandibular disorder (TMD) pain, and oral health-related quality of life (OHRQoL) have been suggested. Due to the limited number of studies, definitive conclusions about the scope of tooth wear in PD cannot be drawn. However, the following propositions can be considered: (1) tooth wear may be more frequent in PD patients compared to healthy controls, (2) risk factors common in the general population could be more prevalent among PD patients, and (3) multiple overlapping factors may contribute to tooth wear, influencing its development and severity in this population.
