Dentures serve as removable replacements for missing natural teeth and the surrounding gum tissues. Understanding their lifespan and recognizing when they need attention is important for continued oral health and comfort. This article provides insights into how often dentures typically require replacement.
Typical Denture Lifespan
Dentures are not a permanent solution and have a finite lifespan. Full dentures generally last 5 to 10 years. This duration can vary based on individual factors and denture type. For instance, partial dentures may last up to 15 years. Immediate dentures, placed after tooth extractions, often require replacement within two years as the mouth heals and changes. Regular assessment by a dental professional is necessary to determine if a denture is still functioning optimally.
Signs of Worn Dentures
Several indicators suggest dentures may no longer fit or function effectively. Dentures feeling loose, slipping, shifting, or clicking during speaking or eating are common signs. This poor fit can also lead to discomfort or irritation of the gums, sometimes resulting in painful mouth sores.
Difficulty chewing food, particularly harder or stickier items, is another indicator. Changes in facial appearance, such as sunken cheeks or an altered jawline, can occur as underlying bone structure changes. Changes in speech, like a lisp or trouble pronouncing words, can also signal ill-fitting dentures. Visible wear on denture teeth, such as flattened chewing surfaces, chips, or cracks, along with persistent stains or discoloration, also point to replacement. An increased reliance on denture adhesives can also suggest a deteriorating fit.
Factors Influencing Denture Durability
Denture longevity is influenced by daily habits and natural biological processes. Consistent proper oral hygiene, including daily cleaning and appropriate storage, extends denture life. Conversely, harsh cleansers or hot water can damage the material, leading to warping or weakening.
Dietary choices also affect durability; frequent consumption of hard, sticky, or abrasive foods accelerates wear. Natural jawbone changes, specifically bone resorption after tooth loss, alter the shape of the gums and jaw, leading to a less secure fit. The initial quality of the denture materials also contributes, with higher quality materials offering greater durability. Regular dental check-ups are important for professional assessments, as adjustments like relines or rebases can sometimes extend the lifespan. Accidental damage, such as dropping dentures, can also necessitate premature replacement.
Next Steps for Denture Replacement
If you notice any signs of worn dentures, consult a dental professional. A dentist or prosthodontist can assess your current dentures and evaluate overall oral health. They will determine if adjustments, such as a reline or rebase, can improve fit, or if a complete replacement is necessary. Only a dental professional can provide an accurate diagnosis and recommend the most suitable course of action.
