Dentures: The Types, the Fitting Process, and the Adjustment Nobody Warns You About
Most of what people want to know about dentures concerns the appointments. The part that actually catches them off guard is the first two weeks afterward.
Dentures come in four forms: complete, partial, immediate, and implant-supported. Getting them takes several appointments — impressions, bite registration, a wax try-in, the fitting, and follow-up adjustments. Complete dentures average about ten years of service. The adjustment period in the first two weeks is normal, and it is the part that surprises people most.
New dentures feel bulky. Speech is briefly odd — S and F sounds especially. Eating takes deliberate practice, starting with softer food cut small and chewed on both sides at once rather than one. Sore spots are normal and are fixed with a quick adjustment, not endured.
Almost everyone adapts. But going in expecting an effortless swap sets you up to think something’s wrong when it’s going exactly as it should.
What are the different types of dentures?
| Type | Replaces | Key consideration |
|---|---|---|
| Complete (full) | Every tooth in an upper or lower arch | Uppers hold by suction against the palate; lowers have less ridge to grip |
| Partial — cast | Gaps around remaining natural teeth | Slim metal framework, precise fit, more durable |
| Partial — acrylic | Gaps around remaining natural teeth | Bulkier and less durable, but simpler to make and adjust — often transitional |
| Immediate | Teeth removed the same day | Gums shrink underneath as they heal, so relining (sometimes remaking) is part of the plan |
| Implant-supported (overdenture) | A full arch, anchored on implants | Solves the movement problem with lower dentures; implants are placed surgically |
Complete (full) dentures replace every tooth in an upper or lower arch, resting on the gums. Uppers get a real assist from suction against the palate; lowers have less to hold onto, which is why lower dentures are the ones people most often find unstable.
Partial dentures fill gaps when you still have some natural teeth. A cast partial uses a slim metal framework for strength and a precise fit. An acrylic partial is bulkier and less durable but simpler to make and adjust, which makes it useful as a transitional appliance.
Immediate dentures go in the same day teeth are removed, so you’re never without teeth. The trade-off is that gums shrink considerably as they heal underneath, so an immediate denture needs relining — sometimes remaking — once healing settles. It’s best understood as two stages, not one.
Implant-supported dentures (overdentures) snap onto implants placed in the jaw. They address the single biggest complaint about conventional lower dentures, which is movement. The implants are placed surgically, and the denture itself is made and fitted to them.
What does getting dentures involve?
Getting dentures unfolds across several visits, and each one exists for a reason.
- Consultation and impressions. Assessment of your remaining teeth, gums, and ridge shape, and initial moulds.
- Bite registration. Establishing how your jaws relate to each other and how much vertical space the teeth need to fill. This determines whether the finished denture looks and works right, and it’s not something that can be rushed.
- Wax try-in. A prototype with the teeth set in wax, so you can check fit, bite, and appearance before anything is finalized. Say what you think here — shade, tooth shape, how much shows when you smile. Changes are straightforward at this stage and difficult afterward.
- Fitting. The finished denture is placed and adjusted.
- Follow-ups. Small refinements as you settle in. Expect at least one, often more, and treat them as part of the process rather than a sign of a problem.
How long do dentures last?
The commonly repeated figure is five to ten years. The evidence says longer.
A review of 42 studies found a weighted mean service life for complete dentures of 10.1 years, with only 12% failing at the five-to-six-year mark — meaning the large majority are still serviceable at the point convention says replace them. The authors noted plainly that textbook three-to-five and five-to-ten year replacement recommendations lack evidence behind them.
| Typical service life | |
|---|---|
| Complete dentures | Mean 10.1 years; only 12% fail by year five or six |
| Removable partial dentures | 75% still in use at five years, 50% at ten |
Removable partial dentures fare less well: roughly 75% still in use at five years and 50% at ten, with free-end designs lower. A meaningful share of patients — around 18% — simply stop wearing a partial.
You’ll also often read that dentures need regular relines. In a twenty-year cohort of over 187,000 adults, only 5.9% ever received one — though that reflects what patients were given, not necessarily what they needed. Relines are a genuinely useful service when the fit has changed; they aren’t a scheduled maintenance item.
What this means practically: don’t replace a denture because a calendar says so. Replace it when fit, function, or appearance has actually deteriorated, and have it checked annually so that call is made on evidence.
How do you care for dentures?
- Rinse after eating.
- Brush daily with a soft brush and denture cleaner. Not regular toothpaste — it’s abrasive enough to scratch the acrylic, and those scratches hold stain and bacteria.
- Soak overnight in water or the cleanser your dentist recommends — never hot water, which warps acrylic, and check first before using any cleanser on a partial with a metal framework. Dentures need to stay moist to keep their shape, and giving your gums a nightly break lowers the risk of denture stomatitis.
- Handle over a folded towel or a basin of water. Acrylic breaks when dropped on a bathroom sink, and this is far and away the most common way dentures get damaged.
- Keep your dental visits. Even with no natural teeth, your gums, ridge, and soft tissues need checking — including oral cancer screening, which doesn’t stop being relevant.
Never try to adjust or repair a denture yourself. Filing a sore spot changes the fit in ways that are hard to undo, and DIY glue repairs usually make a professional repair impossible.
Does insurance cover dentures?
Most plans classify dentures as a major restorative or prosthodontic service, commonly around 50%, subject to your annual maximum and to replacement frequency limits that often run several years.
The Canada Dental Care Plan covers complete and partial removable dentures, both requiring preauthorization. As of April 1, 2026, complete immediate dentures and denture liners no longer need it — a change worth knowing if you were quoted a longer timeline under the previous rules. Implant-supported options are a different matter: implants and all implant-related procedures are excluded from the CDCP.
We direct-bill all insurance companies, and can submit a predetermination so your covered amount is confirmed in writing before work begins.
Denture services at Mellow Family Dental Care
Denture care at Mellow starts with an assessment, and you need that regardless of who ends up making the denture. We examine the ridges and remaining teeth, check the tissues, take any imaging needed, and work out whether a denture is the right answer at all — or whether something else suits your situation better.
For the denture itself, we refer you to a denturist. That’s a deliberate choice, not a gap. Denturists are specialists in removable prosthetics, and the practices we refer to have an in-house lab. That matters more than it sounds. When the lab is in the same building, a try-in that needs adjusting gets adjusted that day instead of being couriered out and returned the following week. For a device that takes several appointments and a run of small adjustments in the first weeks, it cuts the number of trips considerably — which is the part patients actually feel.
We stay involved for the dental side: geriatric dentistry, the health of any remaining natural teeth, and the examinations that keep the rest of your mouth sound while the denturist looks after the prosthesis. If you’re weighing an implant-supported option, we can assess your case and handle the restorative side, coordinating with a specialist for surgical placement.
Common questions
How long will it take to get used to them? Most people adapt within a few weeks. Speech usually settles first; eating confidently takes longer. Reading aloud for a few minutes a day genuinely helps with speech, and starting with soft food cut small helps with eating.
Are sore spots normal? In the first weeks, yes — and they’re easily adjusted. What isn’t normal is persistent pain, so don’t tolerate it. Wear the denture for a few hours before an adjustment appointment so the sore spot is visible.
Do I need adhesive? A well-fitting denture generally doesn’t require it, though some people prefer a small amount for confidence. If you find yourself needing progressively more, that’s a sign the fit has changed and it should be assessed.
How long do dentures last? Complete dentures average around ten years of service. Partials tend to be shorter. Fit and function should drive replacement, not the calendar.
Will I be able to eat normally? Most foods, yes, with practice. Very hard or very sticky items remain more difficult with conventional dentures, and this is where implant-supported options make the biggest difference.
Can I sleep in them? Better not to. Overnight removal lets the tissue recover and lowers the risk of inflammation and fungal infection under the plate.
Does Mellow Family Dental Care make dentures? We provide the denture assessment, which is needed either way, and then refer to a denturist for fabrication and fitting of complete dentures. The denturists we work with have an in-house lab, which means adjustments happen the same day rather than being sent away, so patients make fewer trips.
