Dental implants are replacement teeth made from titanium. They are used to either replace a tooth or be used as an anchor for a denture/partial denture to snap into to keep it from shifting while talking or chewing. Implants preserve your bone. Without teeth, the bone that supports your overlying facial structure begins to melt away and can make you appear older than you are. Implants slow down this process, allowing you to maintain your youthful appearance.
