A patient is given a local anaesthetic for dental treatment. Which instruction is safest until normal sensation returns?
Correct answer: C. Avoid biting the cheek or tongue
- A. Chew food on the numb side
- B. Test hot drinks before swallowing
- C. Avoid biting the cheek or tongue
- D. Massage the numb area firmly
Explanation
Loss of sensation can cause accidental biting or burns, so the patient should avoid chewing and hot drinks until sensation returns. Firm massage does not restore nerve function and may injure the tissue.
