Denture care is an essential nursing and CNA skill. Dentures are expensive, fragile, and easy to misplace, so proper handling is just as important as proper cleaning.
Patients who are ill, bedridden, or have limited mobility may need assistance removing, cleaning, storing, and reinserting their dentures safely. In addition to cleaning the dentures themselves, oral care should always be provided to the patient's mouth.
Why Is Denture Care Important?
Proper denture care helps:
Remove food particles and denture adhesive Reduce bacteria on dentures and in the mouth Improve comfort when dentures are reinserted Prevent damage from drops, hot water, or abrasive cleaners Prevent dentures from being lost or mixed up in healthcare settings
The two biggest priorities are simple:
Protect the dentures from damage. Never lose or mix up the dentures. When Should Dentures Be Cleaned?
Dentures should generally be cleaned:
After meals Before bedtime (most patients do not sleep with dentures) Anytime they become visibly soiled
If the patient cannot perform their own oral care, nursing staff should assist with removing the dentures, cleaning them, providing mouth care, and replacing them if requested.
Supplies Needed for Denture Care
Gather all equipment before beginning:
Labeled denture cup Soft-bristled toothbrush or denture brush Denture cleaning paste Kidney basin or emesis basin Towels or paper towels Gloves
Ask whether the patient has their own denture cleaning supplies or a preferred soaking solution before using another product.
What Should You Use to Clean Dentures?
A denture cleaning paste with a soft denture brush is the preferred method.
Regular toothpaste may be used if necessary, but it isn't ideal. Many toothpaste formulas—especially whitening toothpastes—contain abrasives that can gradually scratch the denture surface.
How to Prepare the Sink Before Cleaning Dentures
Before handling the dentures:
Perform hand hygiene. Put on gloves. Cover the work area with towels. Place paper towels over faucet handles to reduce contamination. Line the sink with towels and partially fill it with water.
Padding the sink is one of the most important safety steps. Dentures become slippery during cleaning, and if they're dropped, the towel-and-water cushion helps prevent cracks or breakage.
How to Clean Dentures Step by Step
- Remove the Dentures Carefully
Assist the patient if needed and place the dentures into the labeled denture cup temporarily.
If the dentures were removed at the bedside, perform hand hygiene and change gloves before cleaning them at the sink if necessary.
- Rinse the Dentures
Turn on warm water—never hot water—and rinse away loose food particles and debris.
- Clean the Denture Cup
Wash and rinse the denture cup before placing the cleaned dentures back inside. Never return clean dentures to a dirty storage cup.
- Brush Every Surface
Apply denture cleaning paste and gently clean:
The gumline Front tooth surfaces Back tooth surfaces Chewing surfaces The palate portion of the upper denture The tongue-side surface of the lower denture
Use gentle strokes to thoroughly remove food, adhesive, and debris without bending or dropping the dentures.
- Rinse Thoroughly
Remove all cleaning paste and remaining debris with warm water.
- Store the Dentures Properly
Place the dentures in the cleaned, labeled denture cup.
Cover them completely with water or the patient's preferred soaking solution to help maintain their shape.
Secure the lid before returning the cup to the patient.
Don't Forget Mouth Care
Cleaning dentures is only part of good oral care.
After removing the dentures, clean the patient's:
Gums Tongue Cheeks Roof of the mouth
If the patient wants to wear the dentures afterward, assist with reinsertion once mouth care is complete.
Cleaning Up After Denture Care
After storing the dentures:
Rinse the toothbrush thoroughly. Remove any trapped debris from the bristles. Wash and dry the kidney basin. Drain the sink and remove protective towels. Remove gloves. Perform hand hygiene.
Cleaning the equipment helps prevent bacteria and residue from carrying over to the next use.

Frequently Asked Questions Should dentures be stored dry or in water?
Dentures should generally be kept moist in water or an approved soaking solution to help maintain their shape.
Can you use toothpaste on dentures?
If necessary, yes. However, denture cleaning paste is preferred because many regular toothpastes contain abrasives that may damage dentures over time.
Why should you pad the sink before cleaning dentures?
Dentures are slippery when wet. Padding the sink with towels and water helps prevent them from breaking if accidentally dropped.
Should patients sleep with dentures?
Generally, no. Dentures are usually removed, cleaned, and stored overnight unless otherwise directed by the patient's healthcare provider.
Why should the denture cup be labeled?
A labeled denture cup helps prevent dentures from being lost or mixed up, especially in hospitals and long-term care facilities.
Bottom Line
Knowing how to clean dentures safely is an important part of nursing and CNA practice. Using warm water, a soft denture brush, proper storage, and careful handling helps protect both the patient and the dentures. Always finish with oral care and store dentures in a labeled cup to reduce the risk of damage or loss.
