On average, how many teeth did patients with advanced periodontal disease lose per year during a 10-year follow-up?

Patients with advanced periodontal disease typically experience significant oral health deterioration, leading to an average tooth loss rate that has been studied and documented in dental research. Evidence indicates that on average, these patients lose about one tooth per year over an extended follow-up period, such as 10 years.

This figure reflects the progressive nature of periodontal disease, where inflammation and infection can lead to the loss of supporting structures around teeth, such as bone and gums. Factors contributing to this tooth loss include the severity of the disease at the outset, the patient's adherence to treatment protocols, and their overall oral hygiene practices.

In studies that have monitored tooth loss over time in patients with advanced periodontal disease, losing one tooth per year aligns well with clinical observations and patient reports. Higher rates of tooth loss tend to occur in more severe cases or among patients who do not receive adequate treatment or maintain poor oral hygiene.
