Scientists: tooth loss may lead to weight gain

Tooth loss may be linked to weight gain — researchers have reached this conclusion after discovering an approximately 17% increased risk of weight gain, particularly when molars are lost.

As reported by TUT.AZ citing the Journal of Periodontology, more than 900 volunteers participated in a large-scale study, with their health monitored over a period of four years. At the start of the experiment, specialists thoroughly assessed the oral health of each participant — the number of remaining teeth and the presence of gum disease. By the end of the observation period, it was found that approximately 12% of those examined had gained at least 5% of their initial body weight.

A detailed analysis of the data demonstrated that people with fewer teeth and pronounced gum problems had a notably higher likelihood of gaining excess weight. The most significant factor was the absence of molars — the large chewing teeth located in the back sections of the jaw. Normally, an adult has three on each side, but when they are lost, the risk of weight gain increased by approximately 17%.

According to the study's authors, changes in diet play a key role in this process. Tooth loss significantly makes it harder to chew solid food, causing people to consume fewer fiber-rich products such as vegetables and fruits. These are replaced by soft and, as a rule, higher-calorie foods.

Specialists emphasize that the condition of teeth and gums directly affects eating habits and, consequently, body weight — especially in older adults. Maintaining oral health could become an important element in preventing excess weight.

At the same time, scientists note that additional research is needed for a more precise understanding of the identified relationship.
