You have tried several things but have not had any luck. You tried topical anesthetic on the soft palate, salt on her tongue, and having her lift her foot. What should you do?

• Skip the images.

• Take extraoral images to gather diagnostic information.

• Switch to a different type of intraoral receptor (film, PSP, or sensor).

• Inject a local anesthetic on her patient’s throat and try again.
