If you wear removable dentures, it is essential that they fit properly in your mouth. When there is a gap between the plate of the dentures and the surface of your mouth due to the dentures being ill-fitting, some problems may occur:

Discomfort in chewing

If your dentures do not fit properly and your mouth is painful or uncomfortable, you will not be able to chew properly. You will most probably be forced to eat only soft foods that are not always necessarily as nutritious as other foods. In this way, problems with your dentures can begin to affect your overall health.

Food may become trapped

Seeds or tiny bits of food can become trapped in the space between your dentures and your mouth. These will cause you discomfort after a while and may even become infected if they are left for a long time, which can lead to your mouth beginning to smell bad.

Infections may breed

Any dark, moist place can be the perfect breeding ground for germs to grow. Even the smallest gap between your dentures and your mouth can be such a site. Even something as commonplace as yeast can grow there. A build-up of yeast can lead to the development of conditions such as cheilosis or stomatitis in your mouth. Both of these can be treated with medication, but the best course is to prevent them occurring in the first place.

Speaking may be affected

If your dentures don't fit properly, you may find it difficult to speak clearly. It can also be painful to have your dentures moving, even slightly, in your mouth. You don't want your day-to-day communication to be affected adversely by something as simple as ill-fitting false teeth.

Sore mouth and gums

Perhaps the most obvious problem that ill-fitting dentures may cause is a sore mouth and gums.  Eventually you will find that you will be unable to even tolerate the dentures in your mouth, which will affect the way you see yourself and your sense of how others see you. You should try to avoid the pain by having your dentures checked regularly and making sure that they always fit properly.

If you have any discomfort because of your dentures, you should see your dentist immediately. Your mouth will change shape, even subtly, over the years and you may find that your dentures will have to be adjusted to accommodate these changes. They may also simply become worn down with use and will need to be relined.
