Abstract: This is a case of a patient presenting to his general dental practitioner (GDP) with altered sensation in his lower lip with no obvious cause. Due to a prompt referral, the patient was investigated and diagnosed with an extramedullary presentation of multiple myeloma. A numb lip can present in general dental practice, although this is not common. There are several causes, for example, dental infection or fractured mandible.

Clinical relevance: It is very important for the dental practitioner to recognize when there could be a potential sinister underlying cause and prompt referral, under the two week rule referral system, is indicated.

Objective: To understand the importance of numb lip as a symptom and refer under the two-week rule when an obvious cause cannot be identified for persisting numbness.
