A dental implant is made of a medical-grade titanium post, a connecting abutment, and a custom crown. Together, these parts replicate the function and appearance of a natural tooth. Dental implants can replace a single tooth, multiple teeth, or all of your teeth (full-arch restoration). They are a popular option for replacing one or more teeth because they look, feel, and function just like a natural tooth. Many people who wear dentures or bridges switch to implants because they are more comfortable and preserve facial structure.
