A missing tooth leaves most patients facing the same question: should I have a dental bridge or a dental implant? Both options replace the visible gap and restore function, but the two treatments work very differently and carry distinct long-term implications for your other teeth and your jawbone. At Fitzroy Dental Practice in Fitzrovia, we give every patient a thorough, honest assessment before recommending either route. Here is what you need to understand to make a genuinely informed choice.
What exactly is a dental bridge, and how does it replace a missing tooth?
A dental bridge consists of one or more artificial teeth called pontics suspended between two crowns that cap the teeth on either side of the gap. Those neighbouring teeth, known as abutment teeth, support the entire structure. The dentist prepares them by removing enamel to make room for the crowns, then fits the bridge as a single, fixed unit.
The result looks and functions like natural teeth and completes the gap immediately. The key clinical trade-off is that healthy, structurally sound neighbouring teeth must undergo permanent preparation to support a bridge even if those teeth would not otherwise need any treatment.
What is the tooth bridge procedure, and how many appointments does it take?
A standard dental bridge typically takes two to three appointments. First, your dentist prepares the abutment teeth, takes an impression or digital scan, and fits a temporary bridge. The dental laboratory then fabricates the final bridge usually over one to two weeks, and your dentist cements it permanently at the second appointment. More complex bridges or those requiring additional work may need further visits.
Does getting a dental bridge require shaving healthy teeth?
Yes, for a traditional three-unit bridge. The abutment teeth on either side of the gap lose a significant layer of enamel to accommodate the crowning caps that anchor the bridge. Once prepared, those teeth require a crown or bridge for the rest of the patient’s life, making the decision to place a bridge irreversible in this respect. Maryland bridges (adhesive bridges) bond to the backs of adjacent teeth with minimal preparation, but they suit only specific situations and carry different limitations in terms of stability.
What is a dental implant, and how does it differ from a bridge?
A dental implant replaces the tooth root, not just the visible crown. The dentist places a titanium post into the jawbone at the gap site. Over three to six months, the bone fuses with the post through a process called osseointegration, creating a stable anchor. A custom-made crown then attaches to the post, completing the restoration as a fully independent unit with no involvement of neighbouring teeth whatsoever.
This independence is the most significant clinical advantage of an implant over a bridge. Adjacent teeth remain entirely untouched, and the implant’s titanium root stimulates the jawbone in the same way a natural root does, preventing the bone loss that occurs beneath a bridge gap over time.
Does a dental implant prevent bone loss in a way that a bridge cannot?
Yes. When a tooth root disappears, the jawbone beneath the empty socket gradually resorbs, losing height and density over time because it no longer receives mechanical stimulation. A bridge replaces the visible tooth but leaves no root equivalent in the bone, so this resorption continues. A dental implant provides direct mechanical stimulation to the jawbone with every bite, preserving bone volume in a way no bridge can replicate.
How long does the implant process take compared with a bridge?
A bridge typically completes in two to three weeks from start to finish. An implant takes considerably longer; most patients complete treatment over three to six months, accounting for the healing period needed for osseointegration. For patients who need bone grafting beforehand, the total timeline extends further. Implants require patience; the wait reflects the biological process of integration rather than procedural complexity.
How long does a dental bridge last, and does it need replacing?
Well-maintained dental bridges typically last between ten and fifteen years, with some lasting longer in patients with excellent oral hygiene and no unusual biting forces. However, bridges rarely last a lifetime. The most common reasons for earlier failure include decay developing beneath one of the abutment crowns, debonding of the cement holding the bridge in place, gum recession around the margins, and fracture of the porcelain facing.
What causes a dental bridge to fail, and are there warning signs?
The abutment teeth underneath the bridge crowns remain at risk of decay they cannot be cleaned conventionally and require patients to thread floss beneath the bridge to clean the margin properly. If decay develops undetected, it can undermine the abutment tooth structure significantly before the bridge shows any visible problem. Other warning signs include a loose or rocking sensation in the bridge, sensitivity, or visible gaps appearing at the margin where the crown meets the gum.
How often should a dental bridge be replaced or checked by a dentist?
Your dentist should check your bridge at every routine examination, looking at the margins, testing stability, and reviewing any X-rays that cover the abutment roots. Most patients replace a bridge once or twice in their lifetime, depending on when it was placed and how well they maintain it. Each replacement cycle involves repeating the preparation and fabrication process and carries an additional cost.
How much does a dental bridge cost in the UK?
NHS dental bridges fall within Band 3 treatment, which carries a fixed patient charge of £332.10, regardless of the number of units in the bridge. This covers a functional restoration but offers limited material choice. Private dental bridge costs in London typically range from £900 to £2,500 or more per bridge unit, depending on the material chosen (ceramic, E.max, or zirconia), the number of missing teeth the bridge spans, and the complexity of the case.
How much more does a private dental bridge cost than an NHS one?
Private bridges reflect higher-quality materials, more appointment time, and greater aesthetic precision than NHS provision typically allows. For a straightforward three-unit private ceramic bridge in London, most patients pay between £1,800 and £4,000 in total. The additional cost typically buys a better aesthetic result, a more refined fit, and a longer expected lifespan.
What does a dental implant and bridge combination cost compared with a single implant?
In cases where multiple adjacent teeth are missing, a bridge supported by implants at each end can offer a cost-effective solution compared with placing individual implants for every tooth. An implant-supported bridge typically costs less in total than the same number of individual implants but more than a tooth-supported bridge, and crucially, it preserves the jawbone beneath all the missing teeth, not just at the implant sites.
Dental bridge or implant: which gives better long-term value?
For most patients replacing a single missing tooth alongside healthy neighbours, an implant provides better long-term clinical and financial value. The higher upfront cost of an implant, typically £1,600 to £2,500 at a quality London practice, reflects a treatment that can last twenty years or more without affecting any other tooth in your mouth.
A bridge costs less initially, but factor in one or two replacements over the same period and the total lifetime cost converges. Add the ongoing risk to the abutment teeth, and the clinical case for an implant where bone and health allow becomes compelling for most single-tooth cases.
Does a dental bridge damage the teeth it is attached to over time?
Not inherently, but the preparation required to place the bridge permanently alters those teeth, and the ongoing hygiene challenge around the margins means abutment teeth carry a higher risk of decay and gum problems than untouched neighbouring teeth would. Whether those risks materialise depends largely on how consistently the patient maintains cleaning around the bridge margins over the years.
Which option does Fitzroy recommend for a single missing tooth, and why?
Where bone volume permits and the patient is in good general health, our clinical team at Fitzroy typically recommends a dental implant for a single missing tooth alongside healthy neighbours. The reasoning is straightforward: it replaces the missing tooth without altering any other tooth, preserves jawbone volume, and, with good maintenance, can comfortably outlast one or two bridge replacements.
