Partial Dentures

A partial denture replaces several missing teeth in an arch while the remaining natural teeth stay in place, using clasps to hold the removable appliance securely against those teeth.

What it’s designed to do

Unlike a full denture, which replaces every tooth in an arch, a partial denture fills in the specific gaps left by missing teeth while leaving healthy remaining teeth untouched. It’s held in position by metal or resin clasps that grip onto some of the remaining teeth, along with a base that rests against the gums in the areas where teeth are missing. This makes it a middle option between a bridge, which is fixed but requires preparing the neighboring teeth for crowns, and a full denture, which is for someone with no remaining natural teeth at all.

The main material options

Cast metal framework partials use a thin, precisely fitted metal frame with acrylic sections shaped and colored to match the gums, plus the clasps. They’re generally the most durable option, tend to feel less bulky in the mouth than an all-acrylic version, and are a common long-term choice.

Acrylic partials (sometimes called a flipper) are made entirely from denture acrylic, including the clasps, and are typically the least expensive option. They’re bulkier and less durable than a metal-framework partial, which is part of why they’re often used as a transitional or temporary solution — for example, right after an extraction while healing occurs before a more permanent replacement is made.

Flexible partials use a more pliable resin, particularly for the clasps, which some patients find more comfortable and less noticeable in the mouth. They can be a good fit for smaller gaps or patients sensitive to the more rigid feel of metal clasps, though they have their own tradeoffs in durability and repairability compared to a metal framework.

How the clasps affect the teeth they attach to

The teeth a partial clips onto do take on some additional function, since they’re now helping stabilize a removable appliance in addition to their normal role. This is why a dentist evaluates the condition of prospective clasp teeth carefully — a tooth with significant existing decay, a large filling, or weak bone support is a less ideal anchor than a solid, healthy tooth. Cleaning around the clasps matters more than around an unclasped tooth, since plaque tends to accumulate at that contact point and can lead to decay or gum irritation there if neglected.

Living with a partial denture

Most partials are removed for cleaning at least once a day, along with brushing the appliance itself the way you would natural teeth, and the remaining natural teeth still need their normal brushing and flossing routine. An adjustment period for eating and, to a lesser extent, speaking is typical, similar to what full denture wearers go through, though usually shorter since more of the mouth’s normal chewing surfaces and sensation remain intact. As with full dentures, the fit can change gradually over time as the gums and any remaining bone in the toothless areas shift, so periodic adjustments are a normal part of long-term wear.
