Factors Influencing Tooth Decay: Beyond Diet & Bacteria

The correct answer is genetics.

Dental caries is a multifactorial disease caused by a combination of factors, including bacteria, diet, and oral hygiene practices. Genetics plays a role in an individual's susceptibility to dental caries, as some people may have a higher risk of developing the disease due to their genetic makeup. However, genetics alone cannot determine whether or not a particular food will result in dental caries. Other factors, such as the frequency and duration of sugar consumption, the type of food, and the individual's oral hygiene practices, also play a significant role in the development of dental caries.
