Your dentist takes impressions and measurements of your mouth to ensure that your dentures will be made well and fit properly in your mouth. While your dentures will probably fit comfortably when you first get them, certain things can make them feel too loose or too tight. Here are three reasons for ill-fitting dentures and what you can do about them:

Weight Changes

While changes in weight are often noticed in the abdomen, thighs, hips, and even the face, gaining or losing weight can cause your dentures to fit improperly. The size of the inside of your mouth can change based on your weight, as you have fat inside your cheeks and other oral structures. If you notice that your dentures slip when eating or talking, or if they feel snug, make an appointment with your dentist. He or she will need to take a new impression so that the dental lab can re-make your appliances to your new specifications. 


Certain medications, both over-the-counter and prescription, can lead to changes in your oral bone structure and gum tissue. For example, a type of anti-seizure medication can lead to a condition known as gingival hyperplasia, which refers to the overgrowth of gum tissue.

If you have this condition as a result of your medications, your gum tissue can become hypertrophied, which can make your dentures too tight. If you take medications to control your seizures, talk to your physician. He or she may lower the dosage or prescribe a new anti-seizure medication that is less likely to cause problems with your gums. 

Degenerative Bone Disorders

If you have a degenerative bone disorder such as rheumatoid arthritis, osteoarthritis, or osteoporosis, your dentures may fit poorly. These bone conditions not only affect your neck, spine, hips, and knees, but they can also lead to bone destruction and diminished bone density inside your mouth.

If you have a degenerative bone disease, work with your physician to manage your condition. Taking your prescribed medications may help prevent future bone destruction, however, they will probably not repair existing damage.

To help prevent bone loss or thinning, eat foods rich in calcium and vitamin D such as cheese, yogurt, milk, and fresh fish. If you are unable to tolerate these foods, talk to your physician about taking an over-the-counter calcium and vitamin D combination supplement, which will help support bone health.

If your dentures are uncomfortable, work with both your dentist and your primary care physician. When the cause of ill-fitting dentures is quickly recognized and treated, the less likely you will be to experience problems with chewing, talking, oral pain, or mouth sores.
