Types of Denture
Dentures fall into three groups according to how they are retained; the key difference is where the support comes from.
Complete dentures
Used when no teeth remain in a jaw. Upper dentures retain well by suction; lower ones are constantly displaced by tongue and lip movement — an anatomical fact rather than a fault. Two implants markedly improve lower denture comfort.
Partial dentures
Used when some teeth remain, retained by clasps or precision attachments. Protecting the abutment teeth is critical, as they carry extra load and are more vulnerable to decay if not cleaned well.
Implant-supported dentures
The denture is supported by implants, either removable (overdenture) or fixed. Reduced palatal coverage improves taste and speech, movement is eliminated, and the implants stimulate bone and slow resorption.
Immediate dentures
Fitted at the same visit as the extractions so the patient is never without teeth. It loosens as the ridge heals, which is expected, and is later relined or replaced.
The Denture Process
A denture is made individually, not mass-produced; the process needs several visits, each with its own purpose.
Examination and planning
Remaining teeth, gum health, bone height and jaw relationship are assessed with a panoramic radiograph, and the possibility of implant support is discussed.
Impressions and jaw relation
A preliminary impression is followed by a precise one in a custom tray. The jaw relationship and vertical dimension are then recorded — an error here compromises both appearance and function.
Try-in and fitting
The teeth are arranged in wax for a try-in — the stage at which shade, size, arrangement and smile line can still be changed easily. Speak up here; changes after processing are usually not possible.
Review appointments
Review appointments matter: pressure points appear in the first days and are relieved by adjustment. Enduring a rubbing denture causes ulcers and tissue change.
Living With a Denture: Care and Adaptation
Success depends as much on use as on manufacture; the first weeks are a learning process.
What to expect in the first days
Fullness, increased saliva and altered speech are normal while the tongue and cheeks adapt. Reading aloud helps, and chewing should start with soft food using both sides at once.
Cleaning
- Rinse the denture after every meal
- Use a denture brush and cleanser; ordinary toothpaste is abrasive
- Clean over a bowl of water so it does not break if dropped
- Brush and massage the palate and gums
- Never use hot water — it distorts the denture
- Remove at night and keep it in its container
Why it should be removed at night
The tissues beneath are under pressure all day and need to rest overnight; continuous wear invites fungal infection and inflammatory changes. Store it in clean water so it does not dry out.
When the denture becomes loose
Continuing bone resorption creates a gap and the denture moves. Relining or renewal is the answer; adhesives are a temporary measure and long-term use accelerates bone loss by retaining an ill-fitting denture.
Mouth Preparation and Assessment Before a Denture
How a denture will sit in the mouth is largely determined during the preparation stage, before the denture itself is made.
What Is Examined at the Assessment
Denture planning starts with a tooth-by-tooth assessment of whatever teeth remain. The dentist looks at mobility, decay and existing fillings, root canal history and gum health. Questionable roots and fractured fragments are dealt with before the denture is made, because they become far harder to reach once a denture is in place.
The clinical examination is usually accompanied by radiographs. Remaining bone height, the shape of the palate and lower ridge, mouth opening and tongue movement all influence which type of denture is appropriate. The same assessment notes conditions such as dry mouth, gum inflammation or denture-related fungal infection.
The Healing Period After Extractions
In patients who need extractions, the gum and bone change shape noticeably in the first weeks. A definitive denture made during that window quickly becomes loose. Healing is therefore allowed to settle first, and the waiting time is set individually according to the number of extractions, bone condition and general health.
An interim denture can be provided during this period so the patient is not left without teeth. It helps maintain chewing and speech and protects the healing tissue. Once healing is complete, the interim denture is replaced by the definitive one; this transition is a planned step, not a setback.
Factors That Shape the Plan
- The number and position of remaining teeth and how much support they can provide
- The height of the upper and lower ridges and the thickness of the gum tissue
- The bite relationship and whether there is jaw joint pain, noise or restriction
- Saliva flow, since a dry mouth makes denture retention more difficult
- General health status and any medication taken regularly
- Manual dexterity, which directly affects inserting, removing and cleaning the denture
- The patient's day-to-day expectations and any previous denture experience
Changes That Appear Over Time With a Denture
Although a denture looks like a fixed appliance, the tissue beneath it changes over the years, so the fit has to be renewed periodically.
Loosening and the Need for Relining
Bone in an edentulous area slowly resorbs over the years under the pressure placed on it. Because the denture itself does not change, the fit deteriorates and the denture starts to rock or shift during meals. This means the underlying foundation has changed, not that the denture has failed.
In such cases it is usually enough to re-adapt the fitting surface to the new tissue shape rather than remake the denture; this procedure is called relining. Timely relining helps prevent accelerated bone loss from uneven pressure and sore spots on the gum.
Speech, Taste and the Gag Reflex
In the first days with a new denture it is normal for certain sounds to come out differently, for the tongue to catch on the borders and for saliva flow to increase. Reading aloud and continuing to talk speed up the tongue's adaptation to the new surface. If the complaint persists beyond the first weeks, the dentist reviews the borders and thickness.
In upper dentures, covering the palate can temporarily dull taste perception and reduce the sense of temperature. In patients with a pronounced gag reflex, the posterior border and palatal thickness can be adjusted, and implant-supported designs may leave the palate open. For this reason the exact nature of the complaint should be described in detail at the review appointment.
Common Mistakes in Denture Use
- Using a denture that no longer fits for years without any check-up
- Trying to trim the denture at home with scissors, files or similar tools
- Attempting to repair a fractured denture with household adhesives or glue
- Soaking it in hot water or boiling it to clean it, which distorts its shape
- Scrubbing it with abrasive toothpaste, which scratches the surface and traps stains
- Masking a poor fit by increasing the amount of denture adhesive
- Postponing an appointment even when sore spots or ulcers have developed
