Why Candidates Fail the Mouth Care (Oral Hygiene) Skill
The resident must be positioned upright at 45–90 degrees before mouth care begins — providing oral care to a flat resident creates aspiration risk and is a critical failure. Candidates must clean the tongue, gum line, and inner cheeks, not just the tooth surfaces. If the resident cannot spit effectively, the candidate must suction or wipe residual toothpaste from the mouth before completing the skill.
How this skill is evaluated
The evaluator scores each skill on a pass/fail checklist. You do not get partial credit. A single critical error — or several minor ones — will fail you on this skill entirely. You must pass all 5 randomly selected skills to pass the clinical exam.
The 5 Most Common Failure Points
Forgetting to raise the head of the bed — this increases aspiration risk.
Not brushing the tongue.
Using too much toothpaste — a pea-sized amount is correct.
Not protecting clothing with a towel.
Removing gloves before all oral care equipment is cleaned and put away.
