The short answer
An implant is placed in the jawbone and can support a crown, bridge or denture. A conventional bridge is supported by nearby teeth. A removable denture sits over the gums and may replace one or several teeth. Suitability depends on the gap, supporting teeth, gums, bone, bite, health, preferences and ability to maintain the result.
Compare what supports the replacement
Ask whether neighbouring teeth would need preparation for a bridge, whether there is enough bone and healthy tissue for an implant, and how a denture would be supported and retained. The answer can change which option is feasible and which other procedures may be needed first.
Compare the stages and total time
A bridge or denture and an implant follow different clinical and laboratory stages. Implant care may include assessment, surgery, healing and fitting the final restoration; bone grafting is not needed for everyone. Ask for the likely sequence, number of visits, temporary options and what could extend the plan.
Compare daily care and future maintenance
Implants, bridges and dentures all need ongoing care. Ask how to clean around the chosen option, which professional reviews are advised and which parts may need repair or replacement over time. A removable denture also changes the daily routine because it is taken out for cleaning.
Compare like with like on cost
Request an itemised estimate that states every stage and component. For an implant, check whether surgery, the implant, abutment, crown, imaging and any grafting are separate. For a bridge or denture, ask about materials, laboratory work, temporary restorations, adjustments and follow-up. Include maintenance as well as the initial fee.
