The main types, and what each is for
The names get used loosely. These distinctions change the treatment, the cost and the timeline.
- Complete denture
- Replaces all the teeth in one jaw. The upper gets real suction from the palate. The lower is a horseshoe working around the tongue, which makes it the harder of the two.
- Partial denture
- Fills the gaps while the remaining teeth stay. A cast metal framework is thinner and stronger than all-acrylic and loads the teeth through small rests rather than the gum. Clasps hold it, and where they show is the trade-off.
- Immediate or conventional
- An immediate denture is fitted the day the last teeth come out, so you are never without teeth, but it is made before anyone sees how the gum heals and needs frequent adjustment. A conventional one is made months later and fits the healed ridge.
- Implant-retained overdenture
- A complete denture that clips onto two or more implants. It rests partly on the gum but is held down firmly, and it is the usual answer to a lower denture that moves.
How a denture is made
Several appointments, each recording something the next stage needs.
-
Impressions and bite records
A final impression in a custom tray records the ridge and how the cheeks, lips and tongue move around it, which is much of what holds a denture in. Wax rims then record the jaw relationship and lip support, which decide the shape of your face.
-
Wax try-in
The teeth are set in wax and tried in, so you approve shade, shape and how much shows when you smile before anything is finalized.
-
Fitting and adjustments
The bite is checked and pressure points relieved. Expect two or three short adjustment visits over the following weeks, and more with an immediate denture. That is planned, not a sign of trouble.
The first month, honestly
A new denture feels large, because the tongue and cheeks have to learn where it is. Most people are through the worst in two to four weeks and more comfortable by three months. Sounds made with the tongue against the palate go first, so s and f and th can be awkward for a week or two, and reading aloud for ten minutes a day sorts most of it out. Saliva increases at first, then settles.
Sore spots matter. A new denture almost always rubs somewhere, and a rub becomes an ulcer within a day or two. That does not mean the denture is wrong, it means it needs adjusting, which takes a few minutes. Do not tough it out, and do not take sandpaper to it yourself, because a denture altered at home cannot usually be corrected. Eating takes longest: soft food cut small, food on both sides at once so the denture is not tipped, and cut rather than bite with the front teeth.
A conventional lower denture compared with an implant-retained overdenture
This is about the lower jaw, where conventional dentures give the most trouble.
| Consideration | Conventional lower denture | Overdenture on two or more implants |
|---|---|---|
| What holds it in | Gravity, the shape of the ridge and muscle control. Adhesive is a workaround rather than a fix. | Attachments that clip onto the implants, so it is held down mechanically. |
| Eating and talking | Can lift or shift on a flat ridge, which narrows what you will attempt. | Stays seated, and a wider range of foods becomes realistic again. |
| Surgery, time and cost | No surgery, weeks from start to finish, lower cost, then relines as the ridge resorbs. | Implant placement plus months of healing, higher cost, and attachment inserts wear and are replaced as routine maintenance. |
Daily care, relines and repairs
Dentures collect plaque and stain as teeth do, and the tissue underneath needs as much looking after as the appliance.
- Brush it daily over a folded towel or a basin of water, using a denture brush and mild soap or a denture cleaner. Toothpaste is abrasive and leaves scratches that hold stain. Dropped on a hard floor, it cracks.
- Take it out overnight and soak it in water or a cleaning solution. Tissue covered around the clock gets inflamed, and denture stomatitis is more common in people who sleep in them. Hot water warps acrylic and bleach corrodes clasps.
- Expect relines, and bring repairs in. The ridge resorbs, so a denture that fitted well stops matching the shape it sits on, and a reline adds material to the fitting surface. Reaching for more adhesive is a signal, not a solution. Superglue is not safe in the mouth and ruins the fracture surface.
Keep coming in even with no natural teeth, because ridges change and an oral cancer screening is part of every examination. See preventive dentistry or contact the office.
Denture questions
How long does it take to get used to dentures?
Two to four weeks for the strangeness to fade and about three months to feel settled, with eating the last thing to come right. A first denture takes longer than a replacement.
Will people be able to tell?
A well made denture with teeth chosen for your face is not obvious. The giveaway with a partial is a clasp, which can often be positioned behind the smile line. Precision attachments avoid visible clasps at a higher cost.
My lower denture will not stay in. Is that normal?
It is very common, and mostly anatomy rather than anything you are doing wrong. A resorbed lower ridge offers little to hold on to. A reline helps when the fit has drifted; when the ridge is flat, two implants with attachments is what solves it.
What do dentures cost, and how often are they replaced?
It depends on complete or partial, whether a metal framework is used, and whether extractions or implants are involved, so you get an itemized estimate first. Replacement after several years is normal. See insurance for how benefits and annual maximums work.
