Dentures are a popular tooth replacement option. They are life-changing for those who have experienced extensive tooth loss. However, after a couple of years, the mouth changes, so your dentures might not fit how they used to. They might seem just like a comfortable inconvenience, but it can actually be a very serious problem. Here’s what you should know.

What Is the Connection Between Ill-Fitting Dentures & Oral Cancer?

Dentures aren’t harmful on their own. However, if they aren’t fitting like they used to, they can cause significant issues. This is because they can trap harmful substances, like alcohol, tobacco, and food debris, between the dentures and the gums, causing inflammation. Chronic inflammation can result in cell damage. These cells will be repaired by your immune system, but if they grow too fast for your body, they can turn into cancer cells. The longer that you have this type of inflammation and irritation, the higher your risk of developing oral cancer. Ultimately, if your denture isn’t fitting comfortably, you should let your dentist know so you can have it addressed.

5 Signs That Your Dentures Are Ill-Fitting

Here are some of the common signs that dentures aren’t fitting as well as they should.

  • Pressure Sores: Sores can result in places where there is too much pressure on the gums. Dentures are meant to distribute the pressure evenly across your gums, so if you are developing sores, you probably are in need of an adjustment.
  • Difficulty Chewing: It takes some time to adjust to chewing after you first get your dentures. If you notice that it is difficult to chew later, it could be a sign that you need a reline or replacement.
  • Bad Breath/Taste: When food debris is stuck between your denture and gums, it can cause a bad taste in your mouth or a foul odor. This warrants a readjustment.
  • Changes in Speech: Ill-fitting dentures shift around when you speak, making it more difficult to say certain words. If you notice that you are slurring, lisping, or salivating excessively while you speak, it might be time for a reline.
  • Discomfort: Dentures take some time to get used to, but if they are particularly uncomfortable, causing jaw soreness, or you feel uneven pressure, you should let your dentist know right away.

If you have issues with your dentures, you shouldn’t try to wait them out. Instead, give your dentist a call. By having this addressed, you can prevent some serious issues down the road.
