Assess any pre-existing comorbidities that may predispose to mouth pain. Assess whether the patient is on steroids, which is a risk factor for thrush.
Characterize the symptom (onset, pace)
Ask the patient:
Is this a new or worsening symptom? When did it start or get worse? Any new medications (e.g., steroids)? Has it developed gradually or suddenly? Have you had any issues with pain in your mouth in the past?
Grade the symptom
Ask the patient:
How much pain are you experiencing in your mouth? Are there actual sores in your mouth or on your tongue? Are your tongue/gums swollen? Is the pain leading you to alter your eating/drinking habits? How much fluid are you drinking per day? Are you able to eat enough? Are you able to swallow?
Ask the patient:
Are you feeling weak, dizzy, or confused? Are you in intense pain?
Consider the following in individualizing the intervention: Is the patient a good or poor historian? Any language barriers or cognitive deficits? Is the patient reliable (able to carry out treatment recommendations)? Does this patient have alcohol/substance abuse issues? Does the patient have transportation? Is there sufficient caregiver support?
Patients with newly emergent moderate or worse mouth pain should be evaluated.
Patients with any of the red-flag symptoms should be evaluated immediately.
What do you suspect is the cause of the mouth pain?
