I have two teeth missing on my upper jaw, on the left side. I am thinking of replacing them, and was looking into getting the most permanent solution possible. I have heard about dental implants, and have heard that they are the best solution for this kind of problem. However, I have recently read that they are not a permanent solution at all, but are only good for like 10 years. Is this true? If it is, then what sort of really permanent solutions do you have? I am 34 years old, and do not want to start losing my teeth.
