These types of foods can increase your risk of cavities
What You Eat Can Affect Your Teeth
A new study suggests that the number of AMY1 gene copies you have plays a crucial role in how the bacteria in your mouth respond to starch, potentially increasing the risk of cavities and gum disease for some people.
The AMY1 Gene: A Key Player in Digesting Starch
The AMY1 gene is responsible for producing salivary amylase, an enzyme that helps digest starch in the mouth. Earlier studies have linked AMY1 to cavities and periodontal disease. However, scientists haven’t fully understood how salivary amylase interacts with starch to disrupt the oral microbiome and increase the odds of dental disaster.
The Study: How Starch Affects the Oral Microbiome
For the study, researchers collected saliva samples from 31 adults, each with different AMY1 copy numbers. They then added starch to the cultured samples, or biofilms, and observed how the bacterial makeup shifted. In samples with high AMY1 numbers, the team found that starch significantly reduced the proportions of two bacteria – Atopobium and Veillonella – while Streptococcus levels increased. All three bacteria are associated with tooth decay or gum disease.
The Takeaway: Starch, AMY1, and the Risk of Cavities and Gum Disease
The study findings don’t mean you should ditch starch from your diet. For most people, starchy foods are an important source of carbohydrates and play a vital role in a balanced diet when eaten in moderation. They provide energy and fiber, along with essential vitamins and minerals. However, for individuals with higher AMY1 copies, the study suggests that they may want to be more vigilant about brushing their teeth after eating starchy foods, as the bacteria in their mouth may be more susceptible to the negative effects of starch.
The Connection between Oral Health and Overall Health
Poor oral health can have far-reaching consequences, extending beyond the mouth to affect the entire body. Researchers have linked poor oral health to a range of serious conditions, including heart disease, diabetes, Alzheimer’s, and certain cancers. Dental and mental health are also closely connected, with gum disease or tooth decay triggering feelings of embarrassment, low self-esteem, and anxiety that can lead to social isolation and a decline in overall quality of life.
Conclusion
The study’s findings could pave the way for more personalized dental care. By understanding an individual’s genetic makeup, dentists might one day offer recommendations tailored to their unique risks when it comes to starch metabolism and oral bacteria. The result? A happier mouth and a healthier you.
