Yea I've done that - its so much cheaper. The only problem is later on if you need a bridge there is less to anchor too, but implants are getting much better so now there is even a solution for that (if it ever even becomes an issue lol)
Only problem with that tho is one of my bridges cost about $1500, one of my implants were $7000
And yes, I will be paying for all this work for a LONG time
