What causes Broken Dentures?

Bad Cleaning

One of the most common causes is improper cleaning of dentures, which may include excessive brushing or using abrasive toothpaste or cleaners.

This can cause the plastic part of dentures to become brittle and eventually crack.

Improper Fit

Another reason why dentures may break is if they weren’t fitted properly in the first place.

They may be too large for the mouth, which can lead to them slipping out when biting into food and either being cracked upon impact with a hard surface or doing significant damage to the gums when forced out.

Additionally, it’s important for users to note that wearing dentures during sports activities could put extra stress on the appliance leading to breakage.


Natural changes in your mouth, such as bone loss from periodontal disease, can cause your denture fit to change over time due to reduced jawbone support, leading to loose-fitting dentures that are more likely to break if knocked around too much.

Wear and Tear

One of the more common reasons for broken dentures is wear and tear, as repeated insertion and removal of false teeth over time can lead to cracks or fractures.


Accidents are also a potential cause of damaged dentures; if the denture user falls or is in an accident, the artificial teeth can suffer significant damage.

How can I maintain my dentures?

In addition to brushing your dentures every night, there are other steps you can take to maintain them properly. First, avoid using any abrasive materials or products when cleaning your dentures.

This includes regular toothpaste and harsh chemical cleaners. Use only soft bristled brushes specifically designed for use with dentures.

It is also important to soak your dentures in a cleansing solution overnight. This will help remove plaque and bacteria that can lead to staining, discolouration, and bad breath.

Soak the dentures in an effervescent cleaner like Polident or Efferdent that contains an active ingredient called sodium perborate, which helps break down food particles and loosens plaque deposits.

Be sure to rinse the dentures thoroughly after soaking, as some of these solutions may contain harsh chemicals that could cause irritation if left on the surface of the denture.

It is also wise to visit your dentist to check your dentures periodically for any signs of wear or damage, especially if you usually struggle with chewing or talking with them in place.
