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