While the aesthetic implications of missing teeth to your smile can be obvious, you may be less familiar with the ways in which tooth loss can alter your facial shape. Beneath the teeth and gums, the underlying jawbone structure depends on the presence of tooth roots to stay healthy and intact. When a tooth is lost and never replaced, this bone begins a slow and steady process of deterioration that can recontour the lower face over time. Consequently, those who live with missing teeth often experience a visible shortening in the distance between their nose and chin, leading to a disproportionate or aged appearance over time.
At Tam Dental Group, Dr. Clarence Tam and our team understand the difficulties of living with tooth loss. As an AACD-accredited Auckland dentist, Dr. Tam knows that this lack of function can affect every aspect of a patient’s life, from their ability to eat certain foods to their daily comfort and self-confidence. We’re happy to help patients in and around the Auckland community restore a more comfortable and carefree quality of life with clinically-proven implant dentistry solutions tailored to renew one’s smile, bite, and lower facial shape. Below, our team explores why bone loss occurs — and how implants can intervene — for individuals facing tooth loss or considering their long-term oral health.
Why Do Missing Teeth Cause Bone Recession?
When you chew, bite, or clench your jaw, these actions provide daily stimulation to the jawbone to maintain its density, volume, and strength. Without this stimulation from a natural tooth root, the bone structure in this region gradually begins to shrink. This process is called resorption, and doesn’t just affect your mouth. As the jawbone diminishes, your facial features that depend on it for support begin to change as well. The lower face can start to look sunken or collapsed, and the distance between your nose and chin may visibly decrease. Cheeks can appear hollow, and fine lines around the mouth tend to deepen. For patients missing several teeth over many years, the overall effect can add years — sometimes even decades — to their appearance.
Dental implants have emerged as the gold standard in tooth replacement, not simply because they look and feel like natural teeth but also due to their ability to address this gradual bone deterioration. By mimicking the function of a natural tooth root, dental implants interact with the jawbone in a way that keeps it stimulated, vital, and structurally sound.
Implant Solutions to Strengthen Jawbone Density
Single Missing Tooth — Dental Implants
For patients who have lost a single tooth and still maintain adequate bone support, a standalone dental implant can represent the most direct and effective tooth replacement available. The procedure involves surgically placing a small titanium post (the implant fixture itself) directly into the jawbone at the site of the missing tooth. Over the course of several weeks to a few months, a process called osseointegration occurs, during which the bone tissue grows around and fuses with the titanium surface. This offers a genuine and biocompatible union between the living bone and implant.
Once the bone-fusing process is complete, an abutment is attached to the implant post and a custom-fabricated dental crown is secured on top. The result is a restoration that looks, feels, and most importantly functions like a natural tooth.
Consecutive Missing Teeth — Implant Bridges
While conventional dental bridges are fixed and functional, they’re anchored to neighboring teeth rather than placed into the jawbone. This means the underlying facial structure never gets the stimulation it needs to prevent the further recession of bone volume. Unlike a traditional dental bridge, an implant-supported bridge is anchored entirely by implants. This provides direct stimulation at the implant sites, halting bone resorption in these regions.
Row of Missing Teeth — Implant-Supported Dentures
For patients who have lost most or all of their teeth in one/both dental arches, implant-supported dentures — sometimes called overdentures or full-arch implant restorations — represent a transformative solution that addresses both the limitations of traditional dentures and their inability to prevent bone loss. Conventional dentures are fabricated to rest against the gum tissue and are held in place by suction or adhesives. Implant dentures are affixed into the jaw, taking advantage of areas where bone volume is typically best preserved. The full or partial denture is then secured to the jawbone, providing the stimulation necessary to maintain bone density. Plus, implant dentures also spare patients from the day-to-day challenges of removable prosthetics, such as messy adhesives, the shifting or slipping of restorations, and the dietary restrictions that come with poor stability.
What Happens if I Don’t Have Enough Bone Support for Implants?
For patients who have delayed treatment and already experienced some degree of bone loss, a bone grafting procedure may be necessary prior to implant placement. Bone grafts introduce new bone material into the deficient area, providing a scaffold upon which new bone can grow and eventually accept the implant. Modern grafting techniques have made this a highly predictable procedure, opening the door to implant-based solutions for patients who might previously have been considered poor candidates.
