Replace four lower incisors with a 6 unit bridge or four implants?

In my practice dental implants are always preferred over fixed bridges assuming the patient is a good candidate for them.  For the lower front teeth we will typically recommend 2 implants and a four unit bridge to fit over them as opposed to four individual implants.  Xrays and an exam would be needed to confirm this with certainty.  Good luck.  

If you are cavity prone, implants may be the better option for you. Having a bridge placed from canine to canine will create areas difficult to clean and maintain. You can get cavities under a bridge. If that happened, you would need a new bridge or may lose the canines to decay, as well. An implant cannot get a cavity. If you have no gum or bone loss, I would recommend implants.

There are many factors that you should consider when making this decision.From your description, it sounds like you may be somewhat prone to cavities. This is important to note because a dental bridge on teeth will make you somewhat  more prone to cavities, whereas a dental implant bridge will have zero chance of ever getting decay.I hope you found this information to be helpful,Dr. Champagne

I would recommend the implant route vs a six unit bridge or 4 root canals, 4 posts, and 4 crowns, provided there is adequate bone.  Advantages of implants are that they will never decay and they stimulate your bone so that it will never  resorb or shrink after extractions.  Four individual implants restored with four crowns will allow for natural flossing, whereas with a bridge, you will need to use a floss threader.  A six unit bridge most likely will not last indefinitely.  If and when it comes time to replace it, you will be dealing with the expense of replacing 6 teeth.If you choose the implant route, be sure that they are placed in the correct position to allow for proper positioning of the crowns that will need to be made to restore your lost teeth.  Implants should last indefinitely if they are placed and restored properly.  If there is ever a problem, you will most likely be dealing with the cost of one tooth, not six.  

Assuming that your lower four incisors are not salvageable and absolutely need to be removed the best solution for replacement depends on many factors.  How strong the canines are; if finances are a factor, and the periodontal health, and the supporting bone remaining should all be considered.  A six unit bridge works great if the canines have good bone support and are sound teeth and this would generally be the easiest and the least expensive solution. If the canines are not in good health then two implants and a 4 unit bridge would be a good alternative. Four implants and four crowns might be the best solution if there is adequate room, but generally this will be more expensive and usually not necessary since the lower incisors are teeth which do not receive a great deal of force.  I  would suggest finding a highly trained and experienced general dentist who is trained in all aspects of dental care to help you make the best decision. If the dentist does not do root canal therapy or periodontal treatment you may get an opinion that would lean towards implants.
