Dental implants. Dental implants are a very common cosmetic choice and are the first step to the next item in this collection of techniques. A dental implant occurs when a person has to have a tooth completely removed. This can happen due to severe damage or simply losing a tooth to an accident. A dental implant could more properly be described as a replacement dental root. A titanium screw is inserted, with the bone then fusing to the metal. After an appropriate amount of healing time and once the implant has properly taken to the bone, then a crown can be added to the implant to give the appearance of whichever tooth it is replacing.
