Dentures: Removable Dental Prostheses for Tooth Replacement

Characteristics and types

There are two broad categories: full dentures that replace an entire arch, and partial dentures that fill gaps when some natural teeth remain. Materials commonly include acrylic resins, metal frameworks, porcelain and modern polymer teeth. Dentures may be retained by clasps, precision attachments, or by dental implants for greater stability.

Indications and benefits

Dentures address a variety of dental problems such as tooth loss from decay, periodontal disease, or trauma. They restore the ability to chew and speak, improve facial appearance by supporting lips and cheeks, and can be a cost‑effective alternative to fixed restorations for many patients.

History and notable facts

The concept of replacing teeth with artificial devices dates back millennia and has been used by humans in diverse cultures. Historical records and artifacts show early dentures fashioned from bone, ivory or metal. Famous wearers include public figures such as George Washington. The broader historical development is covered in many sources on prosthetic dentistry, tracing advances in materials and techniques since ancient times [see history], with evidence of early prosthetic teeth from as early as the 7th century BC in some archaeological contexts.

Care and clinical considerations

Patients are generally advised to remove dentures overnight to allow oral tissues to rest and to reduce risk of irritation or infection. Routine cleaning with a soft brush and specialized cleanser, safe overnight soaking, and regular dental checkups are important to maintain fit and oral health. Ill‑fitting dentures can cause sore spots, bone loss or functional problems and should be adjusted by a dentist.

Types of care and fitting

• Immediate dentures: placed soon after tooth removal to avoid time without teeth.
• Conventional dentures: fitted after healing and tissue stabilization.
• Implant‑supported dentures: attach to dental implants for improved retention.

When considering dentures, a dental professional evaluates oral anatomy, health, and patient goals to recommend the most appropriate prosthesis and follow‑up plan.
