Unsupported Smiles: 4 Complications of Ill-Fitting Dentures

Dentures are supposed to support your smile, but when they don’t fit quite right, they can’t really do that. In addition to slipping and sliding all over the place, an ill-fitting denture can cause several uncomfortable complications or even put your health at risk. Here are four reasons why you should talk to your dentist if your dentures feel loose or can’t seem to stay in place.

#1. Oral Sores

Developing a sore spot on your lip, tongue, or inner-cheek isn’t usually a serious symptom. In most cases, the sore will go away on its own. However, repeatedly getting sores could indicate that your dentures are literally rubbing your soft oral tissues the wrong way! It’s worth securing your comfort and calling your dentist in this case – especially if the sores become inflamed or you experience signs of infection.

#2. Difficulties Chewing

Imagine trying to chew your food when your teeth keep moving or falling out. You face a similar challenge when trying to eat with ill-fitting dentures! A loose set can slip off-center mid-bite, making it difficult to grind down your food. Your best option is to contact your dental team as soon as possible. That way, they can adjust your dentures, and you can go back to eating all of the delicacies you love without worries.

#3. Poorer Enunciation

Did you know that a lot of sounds in English require you to press your tongue against the back of your teeth? Some of the most-used ones are “s,” “th,” and “sh” sounds. As you might suspect, patients with wiggly dentures tend to have a harder time enunciating clearly because of this. Once your restoration has been adjusted by your dentist in Los Angeles, it will be much easier to speak without a lisp.

#4. Increased Risk of Infection

“How on earth does a loose fit increase my risk for infection?” you might be wondering. It has to do with the way dentures sit in your mouth. Normally, they form a perfectly even bite. But if they rest off-center, they can create hiding spots for bacteria, food particles, and saliva to fall into. Over time, this debris can accumulate, building up into infections like gum disease and denture stomatitis.

At the end of the day, your dentures are meant to help you with everyday oral function – not make you feel uncomfortable! If they become loose, your dentist would be happy to reline them for you so that they sit better in your mouth. Alternatively, they can provide you with an implant denture, which is a denture reinforced with titanium implant posts that are anchored to the jawbone for a even more secure hold.

Whichever solution you would prefer, remember that your dentist is there to support you and your dental wellness!
