Denture Liners: The Pros and Cons

How can you tell if the discomfort you’re experiencing is due to the dentures’ fit? You may have worn the denture for many years without problems, and now it may be the reason for your pain.

In this blog, we’ll review the warning signals that can help you identify if an ill-fitting denture is to blame for your discomfort and what you can do about it. 

Even if you just got a new denture, it can still be ill-fitting if it was poorly made or if your mouth has changed since you got the old one. We also discuss the long-term effects of a denture that doesn’t fit right and what happens if the problem is ignored.


What symptoms do I look for?

Discomfort and pain can grab our attention very strongly, especially when they make it hard for us to enjoy our food. If you’ve been wearing dentures and have recently started experiencing discomfort when chewing, it may be time to get a new set. It hurts if the denture moves about in your mouth as you eat. When you bite down hard, the denture moves to a different spot, which is uncomfortable. 

If you do nothing, you will have inflammation and soreness in your gums. Looking in the mirror, you might notice little blister-like ulcers, poor breath, and maybe even bleeding. If you push through the pain in your gums, it will become continuous. One of the risks is getting an infection. 

If the side effects worsen, you may have trouble swallowing food, talking, and breathing. You may be perplexed why this is now occurring with an older denture that has worked fine. You may need clarification about the skill of your oral health provider or the suitability of your new denture.

What causes an ill-fitting denture?

New dentures

Dentures can first feel uncomfortable in the mouth, but this is to be expected. If your mouth is healing from extractions, it may feel uncomfortable and rub your gums, causing sore spots. This can make it hard to tell if the problem is the denture or something else.

However, an oral health professional typically monitors new denture users throughout this transition. If you have any problems, you can bring them up, and they will figure out if it’s due to a bad fit or just a typical settling-in period.


Pre-existing dentures

Even at their best, dentures can’t fully replace natural teeth if you’ve lost them. You must adjust your dentures as you age and your dental health changes. Bones weaken, and gums recede. 

The fit of your partial denture may change if you lose more of your natural teeth or have dental work done. Your denture may feel loose in your mouth, or you may use more glue than usual to hold it in place. This may indicate a need for more suitability.


Difference between upper and lower denture fit

Dentures fit differently in the upper and lower jaws, so knowing the difference is important. Full upper dentures are held in place by suction, while full lower dentures must leave room for the tongue. If you have been toothless for a long, you may need a lower jaw ridge with sufficient bone height for your denture to fit firmly.

Your dentures must rely on your facial muscles if you don’t want them to fall out of your mouth. Each person needs time and practice to develop muscle control in their face. While the practice may not be perfect, it will help you improve at keeping your lower denture in place.


How to find out the problem?

After reading the list of signs above, you may have decided that your pain is caused by a denture that doesn’t fit well. Here is the place to go if you have a new denture and are already seeing a dentist or other oral health professional. 

With an oral evaluation, we can determine the origin of your distress and implement appropriate treatment. If your denture is an older model, a trip to the clinic of your choice, preferably the one that made it in the first place, can calm your fears or confirm them. 

Several denture clinics even provide cost-free, no-commitment consultations, so you may get expert help if you need it.


Long-term effects of ill-fitting dentures

Should you put off getting your dentures adjusted? The following details might cause you to rethink your position. Too loose or tight dentures can develop sores in your gums, which can be embarrassing and make you feel self-conscious about smiling and talking.

Dentures can irritate sore gums by rubbing on them while collecting food debris, germs, and fungi from the mouth. The inability to eat because of discomfort caused by dentures might reduce nutritional intake, leading to feelings of hunger and depression. 

Furthermore, a meta-study examining the associations between dentures and cancer found that poorly fitted dentures raise cancer risk. However, this risk can be reduced with routine dental checkups and increased patient understanding of excellent maintenance routines.


What to do about ill-fitting dentures

Since you are here, reading this post, it’s safe to assume you are taking the initiative to locate a remedy. The first step is to see a dentist or other qualified oral health professional for assistance. If you’re still having trouble, it may be time to consult a dental prosthetist specializing in dentures and how to get the best possible fit. 

Because you are working with the manufacturer directly, you will likely resolve your issue in an on-site laboratory. Second, this is a common problem that dental prosthetists face. Denture-related issues, including ill-fitting dentures, can be avoided or corrected with the help of a dental prosthetist’s expert knowledge of the denture-making process.


A final thought on solving ill-fitting denture problems

It can be helpful to be aware of the signs that a denture isn’t fitting properly so that you can take action if necessary. Dentures that fit poorly or cause pain decrease your quality of life, which may motivate you to seek relief. 

What you do about ill-fitting dentures depends on whether the problem is long-term (due to aging, negligence, or a shift in your oral landscape) or short-term (because you just got them and are still getting used to them). 

The most important thing to remember is that doing nothing will not solve the problem of poorly fitting dentures. Yet, there is a way out, and it’s a pleasant one.
