How to remove plaque from dentures instantly

Dentures provide a valuable solution for those missing teeth, enabling them to enjoy a beautiful smile and functional bite. However, like natural teeth, dentures are also susceptible to plaque buildup, which can lead to oral health issues if not properly addressed.

Plaque is a sticky film that forms on the surfaces of false teeth due to the accumulation of food particles and bacteria. If left unchecked, plaque can lead to tooth decay, gum disease, and bad breath, compromising your oral health and overall well-being.

Regular denture cleaning is essential to maintain their shape, keep them pliable, and extend their longevity. Denture wearers have the advantage of being able to remove their dentures for thorough cleaning, which aids in plaque removal.

Instant Tips for Removing Plaque from Dentures

1. Use a Slightly Abrasive Toothpaste

Choose a slightly abrasive denture toothpaste brand, such as Arm & Hammer, specifically designed for denture cleaning. Simply apply a small drop of toothpaste on a toothbrush or a denture brush and gently scrub all the surfaces of the denture, including the nooks and crannies.

2. DIY Baking Soda Solution

Baking soda is a versatile household item that serves as an effective denture cleaner.

  • Create a DIY denture soaking solution using two teaspoons of baking soda and one cup of warm water in a small glass.
  • Submerge the dentures in the baking soda solution and let them sit overnight to break down plaque.
  • The next morning, use a toothbrush to scrub the dentures thoroughly and rinse them under warm running water.

3. Vinegar for Stubborn Plaque

Vinegar’s high acid content makes it a potent plaque-busting agent.

  • For dentures without metal attachments, place them in a medium bowl filled with white or apple cider vinegar until they are covered.
  • Soak the dentures for at least five hours, or overnight if possible.
  • After soaking, use a toothbrush with soft bristles to give them a quick scrub and rinse thoroughly under running water.

4. Effervescent Liquids for Tough Grime on partials

Effervescent liquids create a bubbling effect that lifts tough grime and helps break it down.

  • For partial dentures, cover the piece with hydrogen peroxide and let it work its magic for 12 hours.
  • Remove the denture from the peroxide, and rinse it thoroughly under warm water.

5. Soak Dentures in Saltwater

Create a saltwater solution by adding a tablespoon of salt to a large glass of water.

  • Submerge the dentures in the glass and let them sit overnight to prevent drying and maintain shine.
  • The next morning, rinse the dentures under sink water before placing them back in your mouth.

Deep Cleaning Dentures

It’s recommended that you give your dentures a deep clean at least once a week for thorough plaque removal. 

For instance, you could prepare a DIY bleach denture cleanser by adding one part liquid bleach to ten parts water in a glass or bowl. Submerge the dentures in the bleach water for 30 minutes, then scrub them with a toothbrush and denture toothpaste to reach all small indentations. Rinse the dentures thoroughly under cold water to remove any bleach traces.

Disinfecting Dentures

Disinfect dentures once a week and as directed if receiving treatment for a fungal infection (such as thrush). Always rinse dentures well under running water before placing in your mouth.

Take care with the choice of denture disinfection products as some may cause the metal components of a partial denture to corrode.

If using a commercial denture cleansing tablet (for example, Steradent)

  • The product used should clearly identify whether it is suitable for either full plastic or partial metal dentures or both
  • Follow the manufacturer’s instruction for soaking time.

Allergic reaction to denture cleansers

Persulphate (persulfate), a denture cleanser ingredient, may cause an allergic reaction. This may happen quickly or after many years, even with correct use.

Symptoms of allergic reaction to denture cleanser include:

  • Irritation
  • Tissue damage
  • Gum tenderness
  • Breathing problems
  • Low blood pressure

If symptoms occur remove dentures and refer to a GP or dentist.

Daily Care and Maintenance

  • Practice good daily oral hygiene by brushing your dentures with toothpaste or a denture cleaner after every meal.
  • Rinse your dentures under warm water before putting them in their case to air dry.
  • Avoid using hard-bristled toothbrushes, harsh abrasives, and whitening toothpaste on dentures, as they can damage the prosthetics.

Regular Dental Checkups

Schedule regular dental checkups, ideally once every six months, or as recommended by your dentist. During these visits, ask your dentist to professionally clean your dentures using powerful denture cleaners to remove stubborn plaque effectively.
