Periodontal disease is most likely to cause tooth loss in which age group?

35-45 yrs
45-55 yrs
55-65 yrs
65-75 yrs

The correct answer is: 65-75 yrs

Periodontal disease can cause tooth loss in any age group, but research has shown that it is most prevalent in individuals over the age of 65. This is due to the fact that as we age, our teeth and gums become less resilient and more prone to infection and disease. While periodontal disease can occur at any age, it is important for individuals in their 65-75 age range to be especially vigilant about maintaining good oral hygiene and seeking prompt treatment for any signs of gum disease to prevent potential tooth loss. Options A, B, and C are incorrect as they suggest younger age groups, which are also at risk for periodontal disease but may not face as high of a likelihood of tooth loss. It is important for individuals of all ages to practice good oral hygiene and to seek regular dental care to prevent any age group from experiencing the negative effects of periodontal disease.
