Amyloidosis secondary to multiple myeloma is well documented in the literature, with amyloid deposits being found at various sites throughout the oral cavity and systemically. This case emphasizes the importance of a full oral soft tissue examination, including the need to examine mobility of the tissues, as it was the restricted movement of the tongue that ultimately alerted the clinician to the diagnosis. This report also highlights other dental implications of managing patients with multiple myeloma and amyloidosis. Clinical relevance: To provide an understanding of what multiple myeloma and amyloidosis are whilst, importantly, relating this to how these conditions can impact on routine dental treatment.
