If you look at the smile of a young child who has just started losing baby teeth, it is common to see one or more gaps in his or her mouth. You may not think missing teeth are seen as frequently in adults, but that is not necessarily true. There are several things that can cause missing teeth in adulthood, including: • Injuries and accidents • Tooth decay • Chronic health problems If you are one of the many adults with missing teeth, there is no reason to simply think tooth loss is something you have to deal with for the rest of your life because you feel too young for dentures. Adults are often missing full arches of teeth and need replacements. Modern technologies such as All-On-4® dental implants make it so many adults can achieve a better quality of life that includes immediate improved functionality of the mouth.
