All-on-4 vs. dentures: an honest comparison

The three options, in plain terms

A conventional denture is a removable set of teeth that rests on the gums. The upper one is held by suction against the palate; the lower one sits on the ridge of the jaw and is held mostly by the cheeks, lips and tongue. It is the least expensive option and the one most people picture when they hear the word.

An implant overdenture is a removable denture that snaps onto two to four dental implants. You still take it out at night to clean it, but while it is in, it does not move. It is the middle option in cost and in stability.

All-on-4 (or All-on-X, when the number of implants is decided by your case rather than by a brand name) is a fixed bridge of teeth permanently secured to four to six implants. It does not come out. You clean it in your mouth, like teeth, and a dentist removes it only for maintenance. It is the most expensive option and the closest thing to having your own teeth back. Our full-arch implants page covers the treatment itself in detail.

What each one costs in Manhattan

These are realistic ranges for the Upper West Side and Manhattan generally, for one arch. They include the surgery, the implants where relevant, and the teeth. Your written estimate will be specific to your mouth.

Conventional denture: roughly $2,000 to $5,000 for a well-made one. Cheaper dentures exist, and they tend to fit and look like cheaper dentures.

Implant overdenture: roughly $9,000 to $16,000 for two implants plus the denture, more with four implants. If you already have a good denture, it can sometimes be adapted rather than remade.

All-on-4 fixed bridge: roughly $25,000 to $45,000 per arch. Both arches typically fall between $45,000 and $80,000.

The honest caveat: a denture is not a one-time cost. Dentures need relining as the jaw changes shape under them, and most are replaced every five to ten years. Over twenty years, a conventional denture plus relines, adhesives and replacements adds up to more than people expect, and the bone loss underneath continues the whole time. An implant-supported option costs more now and generally less in attention later.

How each one feels to live with

Eating. A conventional denture restores perhaps a quarter of natural chewing force; many wearers quietly give up on apples, corn on the cob, steak and crusty bread. An implant overdenture is a large step up because it no longer slides. A fixed bridge restores most of natural chewing force, and after the healing period there is very little you cannot eat.

Speech and confidence. The common complaints with a conventional denture — clicking, slipping mid-sentence, the fear of it moving in company — come from movement. Both implant options remove the movement; the fixed bridge removes it entirely.

Taste and temperature. A conventional upper denture covers the palate, which dulls taste and the sensation of hot and cold. An upper implant overdenture on four implants can often be made without palate coverage, and a fixed bridge never covers it.

Daily care. Dentures and overdentures come out at night and are cleaned in the sink. A fixed bridge stays in and is cleaned with a water flosser and special brushes, and it needs professional cleaning around the implants two to three times a year. That maintenance is not optional, and it is the part of All-on-4 that advertising tends to leave out.

The jawbone. This is the quiet difference. When teeth are gone, the bone that held them shrinks, year after year. A denture resting on the gum does nothing to stop that, which is why dentures loosen over time and why long-term denture wearers develop the sunken look around the mouth. Implants keep the bone working, so the shrinkage largely stops.

Who each option suits

A conventional denture is a reasonable choice when cost is the deciding factor, when health conditions make surgery unwise, or as a short-term step while a longer plan is arranged. It should be well made; a poorly made denture is a false economy.

An implant overdenture is the right answer for many people who have struggled with a lower denture for years. Two implants in the front of the lower jaw transform how it behaves, for a fraction of the cost of a fixed bridge. It is also a sensible choice when bone has thinned too far for a fixed bridge without major grafting, or when a patient wants the security of removing the teeth to clean them.

All-on-4 suits people who want teeth that never come out, who are healthy enough for the surgery, and who are prepared for the cost and the maintenance. It is usually the best outcome available, and it is also the one most often oversold. The number of implants should come from a 3D scan of your jaw, not from an advertisement, and the same specialist should place the implants and make the teeth. Our full-arch page explains why that matters.

Age on its own rarely decides it. Patients in their seventies and eighties have both kinds of implant treatment routinely; general health and the condition of the bone matter far more than the number of years.

How to decide

Start with a consultation and a 3D scan. The scan shows how much bone you have and where, which rules some options in and others out before any discussion of preference. Then be honest about three things: what you want to be able to eat, how you feel about teeth that come out, and what you can comfortably spend, including over the years ahead rather than just this year.

A good prosthodontist will tell you when the less expensive option would serve you just as well. Dr. Jonathan Berkowitz places and restores every option described here in one office at 40 West 86th Street, so the recommendation is not shaped by which procedure the practice happens to offer. If you have already been given a treatment plan elsewhere and want it checked, that is exactly what our second opinion consultation is for.
