Many people facing tooth loss for the first time find themselves searching online for answers about what happens next. Questions such as "How are dentures made?" or "What does getting a new denture actually involve?" are extremely common, and it is entirely natural to want to understand the process before attending your dental appointments.
The acrylic denture fabrication process is a carefully structured clinical journey involving multiple stages, skilled dental professionals, and specialist laboratory work. Far from being a simple procedure, creating a well-fitting, functional acrylic denture requires precise measurements, clinical assessments, and a collaborative approach between your dentist and dental technician.
Understanding what to expect at each appointment can help reduce any uncertainty you may feel, empower you to ask informed questions, and help you better appreciate the craftsmanship involved in producing a comfortable, natural-looking appliance.

Featured Snippet: What Is the Clinical Process of Fabricating a New Acrylic Denture?
The acrylic denture fabrication process involves a series of clinical appointments including impressions, bite registration, trial fitting, and final delivery. Each stage allows the dental team and laboratory technician to customise the denture to fit the patient's mouth accurately, ensuring comfort, function, and aesthetics appropriate to the individual's oral anatomy.
What Is an Acrylic Denture?
An acrylic denture is a removable dental prosthesis made predominantly from acrylic resin — a durable, tooth-coloured plastic material that has been used in dentistry for decades. Acrylic dentures may be complete (replacing all teeth in an arch) or partial (replacing one or more missing teeth whilst remaining natural teeth are still present).

Acrylic dentures are widely used in the UK because they are relatively cost-effective, adjustable, and can be modified or relined over time as the shape of the jaw and gum tissue changes. They are also lightweight and generally well-tolerated by patients who are new to wearing dentures.
Suitability for an acrylic denture, as with all dental appliances, depends on the individual patient's oral health, anatomy, and clinical requirements. A thorough dental assessment is always the first step.
Stage One: The Initial Clinical Assessment
The fabrication of a new acrylic denture begins well before any impressions are taken. Your dentist will first carry out a comprehensive clinical assessment of your mouth, examining the condition of any remaining teeth, the health of your gum tissue, the shape of your ridges (the bony structures beneath your gums), and the overall health of your oral mucosa.
This assessment helps the dental team understand your specific anatomical requirements and identify any underlying issues — such as gum disease, infection, or bone loss — that may need addressing before denture fabrication begins. It is important that the mouth is in a stable, healthy condition before a denture is made, as any changes to the oral tissues afterwards could affect the fit of the appliance.
Your dentist will also discuss your expectations, preferences regarding tooth shade and shape, and any concerns you may have. This conversation is an important part of ensuring the end result is both clinically appropriate and aligned with your personal preferences.
If you have recently had teeth extracted, your dentist may advise waiting for a period of healing before beginning the denture fabrication process, as gum tissue and bone can change shape significantly in the weeks following extraction.
Stage Two: Primary and Final Impressions
Once your mouth has been assessed and deemed ready, the impression-taking stages begin. Impressions are accurate records of the shape and contours of your mouth, which are sent to the dental laboratory to be used as the basis for constructing your denture.

Primary impressions are typically taken first, using stock impression trays filled with a fast-setting impression material. These initial records allow the dental technician to construct a custom-made impression tray that is precisely shaped to your mouth's unique anatomy.
Final (secondary) impressions are then taken using the custom tray during a subsequent appointment. These impressions are far more detailed and accurate than the primary ones, capturing the fine surface detail of your gum tissue and ridges. Different impression materials may be used depending on clinical preference and the type of denture being fabricated.
These impressions are carefully packaged and sent to the dental laboratory, where skilled technicians will pour them in plaster to create precise stone models of your mouth. These models form the working basis for building your new acrylic denture.
Stage Three: Bite Registration and Jaw Relationship Recording
One of the most clinically significant stages in denture fabrication is recording the relationship between your upper and lower jaws — known as the jaw relationship registration or bite registration. This stage is particularly important for patients who are having a complete denture made, where no natural teeth remain to guide the bite.
Your dentist will use wax blocks (called occlusal rims or bite blocks) mounted on a preliminary denture base to record how your jaws meet at the correct vertical height. This helps establish the appropriate vertical dimension of occlusion — essentially, the correct amount the jaw should open and close — which influences both the function and the appearance of the final denture.
At this stage, your dentist will also discuss tooth selection with you. Together, you will choose the size, shape, and shade of the artificial teeth to be set into your denture. Your dentist may take measurements and consider factors such as your face shape, skin tone, and any existing natural teeth that remain.
This information is communicated to the dental laboratory so the technician can begin setting the denture teeth into wax for the next clinical stage.
Stage Four: The Trial Denture Appointment (Wax Try-In)
Before the final acrylic denture is processed, your dentist will invite you back for a trial denture appointment, sometimes referred to as a "wax try-in." At this stage, the dental technician will have set the artificial teeth into wax on the denture base, allowing your dentist to place the trial denture in your mouth and assess it thoroughly before the final materials are used.
During the wax try-in appointment, your dentist will evaluate several important factors:
- Occlusion (bite): How the upper and lower teeth meet and function together
- Aesthetics: The appearance of the teeth and gum-coloured acrylic in relation to your face, lips, and smile
- Phonetics: Whether speech is comfortable and natural with the trial denture in place
- Fit and retention: How well the trial base sits against your gum tissue and ridges
You will also be given the opportunity to look at the trial denture and provide feedback. This is your chance to request adjustments to tooth position, shade, or shape before the denture is permanently processed. Any changes identified at this stage are far easier and more cost-effective to make than after the denture has been finalised.
Once both you and your dentist are satisfied with the trial denture, it is returned to the laboratory for processing.

Stage Five: Laboratory Processing of the Acrylic Denture
The processing stage takes place entirely within the dental laboratory and is carried out by the dental technician. This is where the wax trial denture is converted into the finished acrylic prosthesis.
The technician places the trial denture — with the teeth carefully set in their agreed positions — into a flask (a metal mould) filled with plaster of Paris. Once the plaster has set, the wax is melted away and removed from the mould in a process called dewaxing, leaving a precise cavity in the shape of the denture base.
Acrylic resin dough is then carefully packed into the mould cavity. The flask is closed under pressure and placed into a curing unit — traditionally a hot-water bath — where heat causes the acrylic to polymerise and harden into its final solid form. Modern dental laboratories may also use alternative curing methods such as microwave or injection-moulded techniques.
Once cured and cooled, the denture is removed from the mould and carefully trimmed, shaped, and polished by the technician. The surface is smoothed and refined to ensure a comfortable, hygienic finish with a natural-looking appearance. The completed denture is then cleaned and returned to the dental practice ahead of your fitting appointment.
The Underlying Dental Science: Why Fit and Anatomy Matter
A well-fitting acrylic denture relies on a thorough understanding of oral anatomy and the biomechanics of the jaw. The alveolar ridge — the bony ridge that previously supported your natural teeth — provides the primary foundation for a denture. Following tooth loss, this ridge gradually remodels and reduces in height and width through a natural process called resorption.
This is why the initial impressions must be highly accurate: even small discrepancies in recording the ridge shape can result in a denture that does not seat correctly, causing pressure points, soreness, or instability during eating and speaking.
The oral mucosa (the soft tissue covering the ridges) also plays an important role. Different areas of the mouth have varying degrees of resilience and compressibility, which must be accounted for in the impression-taking process to ensure the denture distributes biting forces evenly.
Saliva also contributes significantly to denture retention, particularly for upper dentures, where surface tension between the denture base and the moist palatal mucosa helps keep the appliance in place. Understanding this science helps explain why each stage of the fabrication process is clinically significant, and why precise impression-taking and bite registration are so important to a successful outcome.
Stage Six: The Fitting Appointment and Post-Delivery Review
At your fitting appointment, your dentist will seat the completed acrylic denture in your mouth and carry out a thorough clinical assessment. They will check the fit, comfort, occlusion, and aesthetics once more, making any chairside adjustments required using specialist instruments.
It is normal for some minor adjustments to be needed at the fitting stage, as the clinical environment differs slightly from laboratory conditions. Your dentist may use pressure-indicating paste or similar materials to identify specific areas where the denture is exerting too much pressure against the soft tissue, and these areas will be carefully relieved.
You will receive guidance on:
- How to insert and remove your denture safely
- How to clean the denture and maintain good oral hygiene
- What to eat during the initial adjustment period
- How and when to wear the denture
- What sensations to expect as you adapt to wearing it
Most patients require one or more review appointments in the weeks following fitting to address any sore spots or comfort issues that develop as they begin wearing the denture regularly. This is a normal and expected part of the process, and you should not hesitate to contact your dental practice if you experience persistent discomfort.
When Professional Dental Assessment May Be Needed
If you are currently experiencing difficulties with an existing denture — or if you are concerned about tooth loss and are considering a denture for the first time — it is always advisable to arrange a professional dental assessment rather than attempting to manage the situation without clinical guidance.
Situations in which a dental consultation may be particularly helpful include:
- Loose or ill-fitting dentures that have become unstable over time due to changes in the jaw ridge
- Sore spots or ulceration beneath the denture base that do not resolve after a short period
- Difficulty chewing or speaking that is affecting daily quality of life
- Cracks or fractures in an existing denture
- Changes in facial appearance, such as a sunken or collapsed look around the mouth, which may indicate significant ridge resorption
- Pain or discomfort beneath the denture, particularly if associated with swelling or redness
If you experience sudden or persistent discomfort related to your denture or oral health, our team at Emergency Dentist in London is available to provide prompt clinical assessment and guidance.
It is important to note that none of the above situations can be appropriately assessed without a clinical examination. Dental symptoms and treatment options should always be assessed individually during a consultation with a qualified dental professional.

Caring for Your New Acrylic Denture: Practical Oral Health Advice
Proper care of your acrylic denture is essential for maintaining both the appliance itself and your underlying oral health. Acrylic resin, whilst durable, is susceptible to damage if dropped and can accumulate bacteria and staining if not cleaned thoroughly.
Daily cleaning guidance:
- Remove your denture after meals where possible and rinse it under running water
- Brush the denture at least once daily using a soft-bristled denture brush and a non-abrasive denture cleaning paste or mild soap — avoid using regular toothpaste, which can be too abrasive
- Soak the denture overnight in cold water or a proprietary denture-soaking solution to help prevent drying and distortion
- Never use boiling water, as this can warp the acrylic material
Oral hygiene for the remaining mouth:
- Even if you wear a complete denture, it is important to clean your gums, tongue, and palate each morning using a soft cloth or soft brush — this stimulates circulation and helps maintain tissue health
- If you wear a partial denture, continue to brush and floss your remaining natural teeth carefully, as partial dentures can increase the risk of plaque accumulation around natural teeth if oral hygiene is not maintained
Handling and storage:
- Always handle your denture over a folded towel or bowl of water to reduce the risk of damage if dropped
- Keep your denture moist when not in use, as prolonged drying can cause the acrylic to shrink and distort
Regular dental check-ups remain important even for patients who wear complete dentures, as your dentist can monitor the health of your oral tissues, assess the fit of the appliance, and check for any signs of oral disease.

Frequently Asked Questions
How long does it take to have a new acrylic denture made?
The acrylic denture fabrication process typically involves five or more clinical appointments spread over several weeks, depending on clinical complexity and laboratory turnaround times. The exact timeline will vary between patients and dental practices. Immediate dentures — fitted on the same day as tooth extraction — may be pre-made before extractions take place, though these often require more frequent adjustments as the gum tissue heals and changes shape in the months following.
Will a new acrylic denture feel comfortable straight away?
Most patients require an adjustment period when wearing a new acrylic denture. It is common to experience increased saliva, mild speech changes, and some initial discomfort as the mouth adapts to the new appliance. These sensations typically improve over the first few weeks. If sore spots or significant discomfort develop, your dentist can make adjustments at a review appointment. The adjustment experience varies considerably between individuals, and your dental team will provide personalised guidance throughout.
How often will I need to replace my acrylic denture?
Acrylic dentures do not have a fixed lifespan, but many patients find their dentures require relining, rebasing, or replacing after approximately five to ten years, as the underlying jaw ridge continues to change shape with age and resorption. Regular dental reviews help identify when a denture is no longer fitting well and whether repair, relining, or a new denture is the most appropriate course of action. The timing will depend on individual factors assessed during clinical examination.
Can an existing acrylic denture be repaired if it breaks?
In many cases, a broken or cracked acrylic denture can be repaired by a dental technician, provided the fracture is straightforward and sufficient material remains to work with. It is important to keep all broken pieces and bring them to your dental appointment, as this helps the technician assess whether repair is feasible. Attempting to repair a denture at home using adhesive products is not recommended, as this can damage the acrylic and make professional repair more difficult.
What is the difference between a complete and a partial acrylic denture?
A complete acrylic denture replaces all the teeth in one or both dental arches and sits directly on the gum tissue and ridges. A partial acrylic denture replaces one or more missing teeth whilst natural teeth remain, and may be retained in place using clasps that engage the remaining teeth. The clinical fabrication process for both types is broadly similar, though the design considerations differ. Your dentist will advise on which type of denture is clinically appropriate for your situation following an oral examination.
Is an acrylic denture the only tooth replacement option available?
No. Tooth replacement options include acrylic dentures, chrome cobalt (metal-framed) partial dentures, dental bridges, and dental implants, among others. Each option has different clinical indications, advantages, and limitations, and suitability depends on the patient's individual oral health, bone structure, medical history, and personal preferences. A dental assessment is necessary to determine which options are appropriate for each individual. Your dentist can explain the relevant alternatives and help you make an informed decision.
Conclusion
The acrylic denture fabrication process is a multi-stage clinical journey that demands precision, skill, and effective communication between patient, dentist, and dental technician. From the initial oral health assessment through to impression-taking, bite registration, the wax try-in, laboratory processing, and final fitting, each step plays a meaningful role in producing a denture that is comfortable, functional, and aesthetically appropriate.
Understanding what each appointment involves can help reduce uncertainty and empower patients to engage actively in their own dental care. Good denture hygiene, regular dental reviews, and open communication with your dental team all contribute to a positive long-term outcome.
If you have questions about dentures or are experiencing concerns with an existing appliance, we encourage you to seek a professional dental assessment at your earliest convenience. Dental symptoms and treatment options should always be assessed individually during a clinical examination.
