Tired or patched acrylic
Discolouration, roughness, cracks or a series of past fixes may all be reasons for a review. The dentist decides whether one local repair would be enough or a new base is the stronger choice.

Denture Rebasing in Mississauga
Most people want to know two things first: can my teeth stay, and how long will I be without the denture? An assessment answers both and shows whether rebasing, a reline or a new appliance fits the problem.
Mississauga · planning a rebasePlan an assessment of your denture
Time, teeth and the part in between
Somewhere between a loose fit and a full replacement sits rebasing. In this procedure the material holding the teeth is removed and a new base is made, and the teeth you already wear are reused, so long as their condition and the way they are arranged still suit you. Because the denture usually has to leave your hands for part of that work, timing is worth discussing early.
Relining can sound similar but is narrower: fresh material goes onto the fitting side and the original base stays. A brand-new denture, by contrast, changes everything. To know which is right, the dentist considers the whole appliance, from how it seats and bites to tooth wear and appearance, alongside the tissues that carry it.
For anyone coming from Mississauga, especially the western neighbourhoods, an unhurried first appointment at our Bronte Street practice saves guesswork later. We look at whether a rebase targets what is really bothering you. Describe past repairs, changes in fit and what you hope to keep, and we will explain why the teeth merit keeping and what a new base can and cannot do.
Is it the base?
Worn acrylic, good teeth, changing fit
Those three often show up together, but they are not the same problem. A rebase is weighed when the base needs replacing and the existing teeth are still sensible to keep.
Teeth worth carrying over
They may look natural to you and still chew comfortably. Wear and arrangement are checked as well, since appearance alone does not show that a rebase is the right call.
Fit that has changed with your mouth
Gums and bone gradually reshape, which can leave a denture less stable. Ask which part of the appliance needs to change and whether the plan accounts for support and bite, not only the base you can see.
Recurring breaks or sore spots call for a look at why they happen. Setting the same unsuitable arrangement into new acrylic would simply bring the problem back.
The case for rebasing
Less change, when less change is enough
If your denture suits it, rebasing renews the base while the tooth arrangement you know stays put. It is a more contained piece of work than a whole new appliance, but containment only helps when the parts being kept are sound.
There are things it leaves untouched. Worn teeth stay worn, an unsuitable bite is not automatically corrected and appearance concerns tied to tooth position remain. It is worth hearing exactly what stays as it is, and which drawbacks you would still live with, before you settle on this instead of a new set.
Patient information: American Dental Association — dental terms
Teeth you are used to
Keeping suitable teeth can preserve the look and bite you have adjusted to. Your clinician should be able to explain how their wear and position were checked.
A thorough fix for the base
When a patch or reline is not enough, replacing the base may be worth considering. Ask what led to that recommendation and how it ties back to the findings.
Grounds for a fair comparison
With an assessment in hand you can line up benefits, limits, appointments and cost for each option. A rebase should be chosen for a clear reason, not to avoid an open conversation about a denture that may have run its course.
How a rebase is organized
Know the timeline before the denture leaves your hands.
Each plan is shaped by the appliance and the work involved. Ask in advance about records, lab time, how long the denture will be away and when you will return for fitting and review.
Examination and history
We look at your gums and the ridges that carry the denture, then at how it seats, how the teeth come together and the state of the acrylic. Your history frames the visit; the current condition settles suitability.
Choose among the options
Repair, relining, rebasing and a new denture are compared against what was found. Be sure you understand what a rebase would change, what it would keep and whether the kept teeth remain well placed.
Records and scheduling
Impressions and other records may be taken to shape the new base. This is the point to settle how long the denture will be away and what you will do in the meantime.
Fit, guidance and review
Once the denture returns, we try it in and look at how it seats, where the teeth touch and how it works when you talk and bite. Care instructions follow, plus a follow-up for anything that surfaces once you are back to normal routines.
Back to everyday wear
Expect the base to feel unfamiliar for a while.
The teeth may be the ones you know, yet the new base changes how the denture meets your mouth. Follow your instructions and mention any difference in comfort or chewing, so the result can be assessed properly.
Wear it the way you were shown
Ask how to start again and whether to take any precautions. If tenderness develops, call rather than persevering just because the teeth feel the same as before.
Update your cleaning routine
A different base material can mean different product advice. Check which brush, cleanser and storage are suitable, especially if your denture has liners or other parts.
Book the fit review
Mention any shifting, pressure points or a bite that lands differently. The review helps show whether a small adjustment is enough or something else needs a closer look.
Mississauga rebasing FAQ(905) 876-4488
Practical questions, straight answers
Rebasing has a defined role. These answers help separate it from relining, repairs and full replacement and cover some practical concerns about timing.
Roughly how long will I be without my denture during a rebase?
It depends on how the work is planned and whether a lab is involved. Ask at the assessment so you can plan, and do not assume an older spare is suitable to wear without having it checked.
Can lower dentures be rebased as well as upper ones?
Either may be considered. Lower dentures often rest on less tissue and can behave differently, so the assessment looks closely at support and fit before suggesting a rebase.
My denture is yellowed but feels fine. Is that a reason to rebase?
Not by itself. Staining may come from the base, the teeth or both, and some can be cleaned. If the material itself has deteriorated, a rebase or new denture may be discussed.
Is a denture that clips onto implants rebased the same way?
Dentures that attach to implants have extra components that affect planning. Bring any details you have, and the dentist will assess whether rebasing, another approach or a referral suits your situation.
Can I eat normally as soon as the rebased denture is fitted?
Ask the clinician what to expect. Some people find it helps to start with softer foods while they get used to the new base, and any soreness should be reported.
Can my Mississauga appointments be arranged around a weekday job?
We open Monday to Thursday until 7pm, with Friday to Sunday by appointment only. Ask at the first visit how many appointments the plan needs so you can book them together.

Get the timing and the options clear in one visit.
At the assessment on Bronte Street we look over the denture and your gums, tell you whether the teeth can stay, and give you a realistic picture of how long the denture would be away if a rebase goes ahead.
Please bring the appliance and what you know of its repairs or relines; this helps us see how its condition has changed.
