Dental implants can be necessary for a number of reasons. Gum disease, extensive tooth decay, mouth trauma, etc., can make implants a necessity. Some dental implants may be needed for aesthetic reasons, such as if there is damage to the front of the mouth that results in tooth damage or loss. In other cases, depending on the location of the damaged or lost teeth, implants may be needed to keep the teeth and jawline properly aligned as well as to prevent issues with eating or speaking.
