Dentures are removable appliances that replace missing teeth, restoring function and appearance. While initially crafted for comfort, the mouth’s shape changes over time, potentially causing dentures to become ill-fitting. Recognizing signs of oversized dentures is important for maintaining oral health and comfort. This article outlines these signs and appropriate steps to take.
The Importance of Proper Denture Fit
A well-fitting denture is important for oral health and daily comfort. Correctly fitting dentures prevent discomfort, including sore spots and irritation on the gums. A snug fit also reduces the risk of gum inflammation (stomatitis) and other oral infections, which can occur when gaps harbor bacteria.
Proper fit also prevents accelerated jawbone resorption. Well-fitted dentures distribute pressure evenly across the jawbone, mimicking natural tooth function and providing necessary stimulation. This helps preserve facial structure and maintain overall oral health. Beyond physical comfort, a good fit enables clear speech, effective chewing, and boosts confidence and quality of life.
Key Signs Your Dentures Are Too Big
Several observable signs can indicate your dentures might be too large. Slipping or excessive movement, where dentures feel loose, shift, or even fall out during routine activities like speaking or chewing, indicates an oversized base cannot properly adhere. Difficulty speaking clearly, including slurred words or whistling sounds, can also arise from dentures that feel bulky and impede tongue movement. When dentures are too large, they can make eating challenging, leading to trouble chewing effectively, food getting trapped underneath, or a sensation of the mouth being overly full.
Sore spots, irritation, or ulcers on the gums are another sign, resulting from the denture base rubbing against soft tissues. Changes in facial appearance, such as lips appearing too full or a distorted profile, can occur if dentures provide too much volume. A persistent gagging sensation may be triggered if the denture base extends too far back, stimulating the gag reflex. Excessive saliva production can occur as the mouth adapts. Clicking or popping sounds during chewing or speaking often signal unstable denture movement.
Steps to Take for Ill-Fitting Dentures
If you suspect your dentures are too big, avoid attempting to modify them yourself. Home adjustments can damage the dentures and potentially harm your oral tissues. Instead, contact a qualified dental professional to assess and adjust them.
Your dentist can perform several interventions to address ill-fitting dentures. Minor adjustments involve precise reshaping of the denture to relieve pressure spots or improve stability. If gum contours change, a reline might be recommended, adding a new layer of material to the denture base to enhance its fit.
In cases of significant anatomical changes, a rebase might be necessary, replacing the entire denture base while retaining the original teeth. If existing dentures are beyond repair or adjustment, your dentist may suggest new dentures. Since oral anatomy can change over time due to jawbone shrinkage, regular dental check-ups are important for maintaining denture fit and comfort.
