Dental agenesis is a condition where one or more teeth fail to develop. It can affect both primary (baby) teeth and permanent (adult) teeth. This condition can lead to gaps in the smile and may impact chewing and speech. The most commonly affected teeth are the wisdom teeth, premolars, and incisors. The exact cause of dental agenesis is often unknown, but it can be linked to genetic factors. Some individuals may have a family history of missing teeth. Treatment options include dentures, bridges, or implants to restore function and appearance, depending on the severity of the condition.
