Since bridges require at least three crowns joined together over the missing tooth and are cemented in place, they can be difficult to floss and clean -- you will most likely need to purchase a specific tool that helps you brush underneath the false tooth to ensure bacteria doesn't flourish. Dental implants, on the other hand, are much easier to manage. They only replace the single tooth, making brushing and flossing almost exactly the same as it was before you needed to have the implant put in.
Dental bridges require your adjacent teeth to be "prepared" and filed down in order to create the foundations of the bridge. Since part of your natural teeth still exists underneath the prosthesis, they usually need to be replaced every 10 years or so. On the contrary, implants can last a lifetime due to the metal (usually titanium) base that fuses directly with your jawbone.
Dental bridges are more affordable in terms of base cost, but the balance can tip in favor of implants once you consider the fact that they will need to be replaced at some point. Although implants are initially more expensive, they will last as long as you do! Luckily, most insurances can assist in covering costs for both procedures.
So, what does this mean for you? All signs may point towards dental implants as being the most logical choice, but if the teeth surrounding the one that needs to be replaced are damaged or have fillings that will need to be redone at some point, bridges can be the better option. It's important to consult with your dentist about this decision as they will have a better understanding of your current oral state and history.
