How to Clean Your Dentures

A simple guide to keeping your dentures and mouth healthy every day.

Why Cleaning Matters: Bacteria and Your Health

Within minutes of putting your dentures in, bacteria begin to stick to the surface. If not cleaned away daily, this builds up into a biofilm. Over time, biofilm hardens into plaque, a tougher deposit that can only be removed by your prosthetist.

Plaque build-up can cause bad breath, gum soreness, oral thrush, and in some people may contribute to chest infections. Daily cleaning keeps bacteria at a low level and protects your mouth and general health.

Step-by-Step Cleaning Guide

1. Rinse Your Dentures

Remove your dentures and rinse them under lukewarm running water to wash away loose food and debris. Try to do this after every meal.

  • Never use hot or boiling water as it can change the shape of your dentures.

2. Apply a Denture Cleaner

Use a denture-specific cleaner or a small amount of mild dish soap with a soft-bristled denture brush. Do not use regular toothpaste as it is too scratchy and can damage the surface of your dentures.

  • Avoid whitening toothpaste and products containing bleach as these can damage your dentures.

3. Brush All Surfaces

Gently brush all surfaces of your dentures including the inside, outside, and chewing surfaces. Pay attention to areas that sit against your gums, and any clips or attachments.

  • Do not scrub too hard as this can cause scratches. Be gentle with any metal clips to avoid bending them.

4. Rinse Thoroughly

Rinse your dentures well under lukewarm running water to remove all traces of soap or cleaner before putting them back in your mouth.

5. Remove Overnight

Removing dentures overnight is generally recommended to give your gums a rest, but this is based on individual need. Some people, such as those who wear a CPAP or sleep apnea device, may need to keep their dentures in at night for the device to fit correctly. Talk to your prosthetist about what is right for you. If you do use a soaking solution, follow the manufacturer's instructions on the packet.

  • Always store your dentures in a container with a lid. Never leave them on a bedside table or wrap them in a tissue. Countless dentures have been accidentally thrown in the bin because they looked like rubbish, and dogs are notorious for chewing them. A dedicated denture container keeps them safe.

6. Morning Routine

Before putting your dentures back in each morning, rinse them under running water. Also gently brush your gums, tongue, and the roof of your mouth with a soft toothbrush to keep your mouth clean and healthy.

How Often Should You Clean?

Daily

  • Brush dentures at least twice a day
  • Rinse after meals
  • Remove dentures overnight
  • Clean your mouth before putting dentures back in

Regular Checkups

  • See your prosthetist every 6 to 12 months
  • Have your dentures professionally checked
  • Ask about fit, wear, and any concerns you have

Struggling with Cleaning? Try an Ultrasonic Cleaner

If you have difficulty gripping or handling your dentures due to arthritis, tremors, or reduced hand strength, an ultrasonic denture cleaner can be a helpful option. These small devices use sound waves to loosen and remove debris and bacteria from all surfaces of your dentures without the need for brushing. They are available at most pharmacies and online. An ultrasonic cleaner works best when used alongside a rinse, not as a complete replacement for brushing. Ask your prosthetist if one might be suitable for you.
