Is it okay to fixed bridge using canine and wisdom as abutments and four continuos molar pontics?

That is a long span for a bridge and expecting it to have many years of service without problems. The canine would be a strong abutment but the wisdom tooth can be questionable. The biggest problem is the span all functioning off of two teeth. A better option would be 4 implants or in finances are an issue; a 4 unit bridge with 2 implants and two pontics in between. Good luck.
