Periodontitis (colloquially parodontosis) is an inflammation of the so-called periodontium, which is responsible for holding the teeth in the jaw. As bone breaks down, teeth loosen and become loose. Periodontal disease usually progresses without any symptoms that are noticeable for a long time and, if left untreated, will inevitably lead to tooth loss.
The good news: in combination with regular professional tooth cleaning in aftercare, periodontitis has a very good prognosis today and can be stopped in the early stages with the right treatment.
