Implants are another alternative to replacing missing teeth within your mouth. It is a gradual process. Some say that implants look and feel very natural. An implant is fused to the jaw bone below the gum line for stability and support. Then a post and an implant crown are placed to complete the process. This is a gradual process and will take several appointments to complete. However, for someone to be a candidate for implants, they have to be in good oral health with adequate bone support and healthy gums.
