Delaying Dental Implants: How It Erodes the Jawbone, Doctors Explain

When a tooth is lost and not replaced, the bone in that area begins to deteriorate within the very first year. Specialists refer to this process as bone resorption: in the first 12 months, up to a quarter of the width of the bone ridge can be lost, after which the recession continues slowly, year by year, for the rest of a person's life.

Why bone is lost

The jawbone requires constant stimulation to maintain itself. With every bite, force is transmitted through the tooth's root to the bone — a signal that tells the body that area is still needed. When the tooth is no longer there, that signal disappears, and the body reduces the resources allocated to it: the bone ridge narrows and decreases in height.

Dr. Mihai Cîrstea, a specialist in oral and maxillofacial surgery at the Dental Premier clinic in București, explains: "Patients think that a missing tooth at the back, where it can't be seen, can wait. The bone doesn't wait. When we see patients for a single tooth lost ten years ago, we frequently find that the neighbouring teeth have tilted into the gap, and the bone has receded to less than half its original height."

An effect that spreads

The problem doesn't remain confined to where the missing tooth once was. Neighbouring teeth shift towards the empty space and lose their correct contact position, whilst the tooth on the opposing arch drifts in search of its lost counterpart. The bite becomes unbalanced, forces are redistributed across the remaining teeth, which wear down more quickly. When several teeth are missing, the cheeks and lips lose their support, and the appearance of the face changes noticeably — with the ageing effect characteristic of untreated tooth loss. What began as a simple extraction can, over time, lead to the need for full-arch rehabilitation.

Can something still be done after years of delay?

Yes. Modern implantology offers solutions even in cases of advanced bone atrophy: bone grafting, sinus lifts that restore lost volume, angularly placed implants that make strategic use of the remaining bone, as well as All-on-4 and All-on-6 protocols, designed specifically for resorbed bone ridges.

Dr. Cîrstea states: "Cases that other practices declare impossible make up a significant part of our work. We plan using 3D tomography, millimetre by millimetre, and we almost always find a fixed solution. But every year of delay narrows the options and drives up the cost."

Dental Premier clinic has over 17 years of activity, more than 33,700 implants placed, and audited certifications from manufacturers including DentSply Sirona, Straumann, MegaGen, and Bredent. According to the clinic's representatives, they treat patients every week who have put off the decision to replace their missing teeth for too long. The message from the doctors is not one of blame, but of time: an initial assessment commits you to nothing, yet it reveals the exact stage of bone resorption and the real treatment options available.

Frequently asked questions

• How quickly is bone lost after an extraction? Most rapidly in the first year, when up to 25% of the bone ridge's width can be lost; the process then continues slowly, indefinitely.
• Does a removable denture stop bone resorption? No. A denture rests on the gum rather than stimulating the bone, and the pressure it exerts can actually accelerate bone ridge recession.
• Does a dental implant stop bone loss? Yes, in the area where it is placed. The implant takes on the role of the natural root and transmits chewing forces to the bone, maintaining the stimulation it needs.
