Why do old people put dentures in water? The complete guide

Millions of Americans rely on dentures, and proper maintenance is a cornerstone of their daily routine. A common practice for many is soaking them overnight, but understanding exactly why old people put dentures in water is key to appreciating its importance for dental and overall health.

Quick Summary

Soaking dentures in water or a cleaning solution prevents them from drying out, which can cause the material to warp and lose its fit. This vital habit also helps sanitize the appliance by killing bacteria and gives oral tissues a necessary rest.

Key Points

• Prevents Warping: Soaking dentures in water keeps the acrylic material hydrated, preventing it from drying out and losing its proper shape and fit.

• Controls Bacteria: Overnight soaking, especially with a denture cleanser, kills harmful bacteria and removes plaque, reducing the risk of oral infections and bad breath.

• Rests Oral Tissues: Taking dentures out at night gives the gums and soft tissues a break from constant pressure, which promotes healing and prevents irritation.

• Enhances Hygiene: Soaking is more effective than brushing alone for disinfecting the microscopic pores of the denture material where bacteria can hide.

• Prolongs Appliance Life: Proper nightly storage and cleaning prevent brittleness and damage, extending the functional lifespan of the dentures and protecting your investment.

Preventing Warping: The Main Reason for Soaking

One of the most fundamental reasons for the practice is to prevent the dentures from drying out. Most dentures are made from porous acrylic material. If this material is left to dry when not in use, it can become brittle and lose its shape. This warping can lead to an improper fit, causing discomfort, rubbing, and painful sores on the gums. Storing them in water ensures the material remains hydrated and maintains its original form, which is essential for a stable and comfortable fit.

More Than Just Hydration: Enhancing Hygiene and Health

While hydration is critical, soaking is also a powerful tool for maintaining excellent oral hygiene, especially in later life. Like natural teeth, dentures accumulate bacteria, plaque, and calculus throughout the day. Leaving this buildup unchecked can lead to several health issues:

• Oral Infections: Unclean dentures can harbor fungi like Candida albicans, leading to conditions such as denture stomatitis, which causes redness and irritation of the oral tissues.
• Bad Breath: The accumulation of bacteria on the denture's surface can lead to foul odors, which regular rinsing cannot fully eliminate.
• Gum Disease: For those with partial dentures, bacteria can transfer to remaining natural teeth and gum tissue, increasing the risk of gum disease.
• Pressure Sores: Plaque buildup can alter the surface of the denture, creating uneven pressure points that lead to sores and irritation on the gums.

Giving Gums a Rest: The Nightly Decompression

Removing dentures at night serves a crucial purpose beyond simply cleaning them. It provides a much-needed rest for the gums and soft tissues in the mouth. Throughout the day, the pressure of biting and chewing is absorbed by these tissues. Allowing the gums to breathe overnight promotes circulation and gives the tissues time to heal, reducing swelling and the development of sore spots. Most dentists recommend taking dentures out for at least eight hours every day for this reason.

Choosing the Right Soaking Solution

Not all soaking solutions are created equal, and some can even damage dentures if used incorrectly. Here is a comparison of common options:

Feature	Plain Cool Water	Commercial Denture Cleanser	Mild Soap
Primary Function	Hydration	Cleaning & Disinfection	Cleaning
Benefits	Prevents warping; simple and safe	Kills 99% of bacteria; removes stains and odor	Non-abrasive cleaning
Disadvantages	Less effective at killing bacteria and removing buildup	Can contain chemicals; requires thorough rinsing	Must be thoroughly rinsed to avoid taste/ingestion
Best for	Routine overnight storage for hydration	Comprehensive overnight cleaning and sanitizing	Gentle daily or occasional cleaning

A Guide to Proper Soaking and Care

Following a consistent daily and nightly routine is the most effective way to ensure dentures remain clean, hygienic, and well-fitting for years to come. The American College of Prosthodontists provides valuable guidelines.

1. After Meals: Remove and rinse your dentures under running water to clear away food particles. Doing this over a folded towel or a sink filled with water will cushion them if they are accidentally dropped.
2. Brushing: At least once a day, use a soft-bristled denture brush and a non-abrasive denture cleanser to gently brush all surfaces of the appliance. Regular toothpaste can scratch the material, creating microscopic grooves where bacteria can grow.
3. Nightly Soak: Place the dentures in a glass or denture container filled with lukewarm or cool water, or a recommended denture-cleaning solution. Never use hot or boiling water, as this will cause the material to warp.
4. Morning Rinse: Before reinserting your dentures, rinse them thoroughly to remove any residual cleaning solution. If a cleanser was used, this prevents irritation to your gums.
5. Clean Your Mouth: Use a soft-bristled brush to gently clean your gums, tongue, and the roof of your mouth. This helps stimulate circulation and removes bacteria.

Understanding the Dangers of Not Soaking

Ignoring the nightly soaking ritual carries significant risks that can compromise both the health of the mouth and the lifespan of the dentures. The acrylic base is designed to remain moist; allowing it to dry out, even for a short period, can permanently alter its shape and make it ill-fitting. This can lead to persistent gum irritation, painful sores, and a heightened risk of infection. Furthermore, neglecting proper cleaning allows harmful bacteria and plaque to build up, contributing to bad breath and oral infections like thrush. Taking proper care of dentures is not just about cleanliness; it's a vital part of a comprehensive oral health strategy, particularly for older adults.

Frequently Asked Questions

Can I use hot water to soak dentures?

No, you should never use hot or boiling water to soak dentures. The high temperature can cause the acrylic base material to warp and lose its precise shape, which will result in an uncomfortable or loose fit.

Is it okay to sleep with dentures in my mouth?

It is not recommended to sleep with removable dentures in. Your gums and other oral tissues need a break from the pressure of the appliance. Removing them allows the tissue to rest and helps prevent inflammation and irritation.

Is soaking in just plain water enough for cleaning?

While plain water will keep dentures hydrated and prevent warping, it is not enough for thorough cleaning. It's best to use a denture cleanser solution or mild soap to effectively kill bacteria and remove plaque buildup.

What is denture stomatitis?

Denture stomatitis is a common oral infection that causes the tissue under the denture to become red and inflamed. It is often caused by a buildup of fungus and bacteria on an unclean denture.

What should I avoid using to clean my dentures?

Avoid using regular abrasive toothpastes, bleach, or other harsh household cleaners. These can scratch, discolor, or weaken the denture material. Stick to non-abrasive denture cleaners or mild soap.

How often should dentures be cleaned and soaked?

Dentists recommend a daily routine of cleaning and soaking. This includes rinsing after every meal, brushing at least once daily with a denture brush, and soaking them overnight.

What should I do if my dentures feel loose?

If your dentures feel loose or cause discomfort, it is important to see your dentist. An improper fit can cause irritation and sores. Your dentist may need to reline or adjust them.
