4 Unfortunate Complications of Wearing Ill-Fitting Dentures
October 6, 2025

As you age, your gums and jawbone will start to change shape, which means your once perfectly-fitting dentures will slowly become…well, less perfectly-fitting. It’s understandable to think that continuing to wear ill-fitting dentures won’t affect you all that much. However, the truth is quite the opposite! Here are four unfortunate complications that can happen if you wear ill-fitting dentures for too long.
#1. Oral Discomfort
If your dentures aren’t shaped quite correctly, they’ll start to rub your gums the wrong way – literally. You’ll likely experience chafing, irritation, sensitivity, and could even develop oral sores. Swelling and inflammation are also inevitable when your dentures don’t rest properly on your gums!
#2. Difficulties Eating and Speaking
Dentures that don’t fit the shape of your mouth will have a hard time staying fixed in place. This means you’ll experience instances of slippage more and more frequently. Imagine trying to eat your favorite meals or hold a conversation when your dentures won’t stay still – it’s difficult, to say the least! What might start out as an inconvenience can become a very real problem if you don’t get your dentures adjusted.
#3. Dental Damage
Not even partial dentures are safe from the consequences of a poor fit. Since partials have a metal clip that keep them secure, the metal can grate against nearby natural teeth if it becomes too loose. Plus, an imprecise shape could cause you to rest your bite improperly, which is associated with an increased risk of dental damage.
#4. Angular Cheilitis
A misaligned bite can contribute to yet another unfortunate problem: angular cheilitis. Whether you have a full set of dentures or partials, an uneven oral structure can cause saliva to pool at the corners of your mouth. When this happens, bacteria accumulate near the saliva, which can result in this uncomfortable yeast infection. Angular cheilitis appears as red streaks or patches and can be quite itchy and painful.
Overall, wearing dentures that no longer fit your mouth simply isn’t worth it. If you experience any of these problems, it’s probably time to have your restoration relined, readjusted, or replaced. Whatever happens to be the appropriate solution, you can count on your dentist to take care of it promptly so you can go back to being comfortable and at ease.
