Complete Dentures: The First Year and Beyond

What complete denture involves

A complete denture replaces all the teeth in one jaw. It is an acrylic base shaped to the ridge and palate, carrying a full set of denture teeth, held in place by suction, muscle control and the fit of the base against the tissue. Making one conventionally takes four to five appointments: impressions, a second set of accurate impressions in a custom tray, records of how the jaws relate and where the teeth should sit, a try-in in wax that can be adjusted before anything is finalised, and delivery. An immediate denture is the same appliance made in advance and fitted on the day the remaining teeth are extracted, so the patient never appears in public without teeth. The trade-off is fit: the ridge changes shape substantially as it heals, so an immediate denture always needs relining, often within months.

When this treatment is used

Used where all the teeth in an arch are missing or are being removed. The upper arch is the more successful of the two, because the palate provides broad support and a good seal; lower complete dentures have far less to hold onto and are the most common source of dissatisfaction in prosthetic dentistry.

What to expect in the first months, honestly

A new complete denture feels enormous, produces excess saliva, changes speech, and makes eating difficult for weeks. That is normal and it improves. What also happens is that sore spots develop where the base presses unevenly, and these need adjusting — expect two or three adjustment visits in the first month and do not try to endure a sore spot, because the tissue underneath will only get worse. The lower denture is the harder adjustment. It sits on a narrow ridge with the tongue on one side and the cheek on the other, and it moves. Patients who expect it to behave like upper teeth are disappointed; patients who understand in advance that lower dentures rely on learned muscle control do considerably better. Two implants in the lower jaw with a snap-on attachment (D6110/D6111) transform that experience, and it is now widely considered the minimum standard of care for a lower edentulous arch where it is feasible. Anyone being offered a conventional lower complete denture should at least have the conversation.

Bone loss, and why dentures need remaking

The ridge shrinks after teeth are lost — quickly in the first year, then slowly and continuously for the rest of life. A denture that fitted perfectly at delivery is resting on a different shape five years later, which is why relines (D5730–D5761) and rebases (D5710–D5721) exist, and why dentures are generally remade every five to ten years. Plans reflect that: most will pay for a replacement denture only once every five, seven or ten years. Keeping a denture going with relines between replacements is both clinically sensible and financially necessary for most patients.

Costs and insurance in summary

Typical fee range across the group: $0–$0 where a single band applies. Several codes here are priced individually and carry their own range on their own page. Priced per arch. Immediate dentures cost more than conventional ones because of the additional planning, and the reline that follows is a separate charge.

Benefit category: Major prosthodontic, typically 50% on a typical plan. Covered as a major prosthodontic benefit with a waiting period and a replacement frequency limit. The annual maximum is usually the binding constraint.

Common restrictions: Waiting periods of 6–12 months are common; Replacement typically limited to once every 5–10 years; Adjustments and relines within the first six months are often included in the fee; Missing tooth clauses may exclude teeth lost before the policy began.
