Can Seed Oils Cause Cavities? Understanding The Relationship Between Diet and Dental Health

Seed oils are a common ingredient in many processed and packaged foods, and are often used in cooking and baking due to their affordability and versatility. However, recent research has raised concerns about the potential impact of seed oils on oral health, particularly their role in the development of dental caries or tooth decay. Dental caries are a common oral health issue that can lead to pain, infection, and tooth loss if left untreated.

While there are no direct longitudinal studies linking seed oils to tooth decay, their effects on the oral microbiome and mineral absorption may contribute to its development. The purpose of this article is to explore the potential impact of seed oils on dental health and provide tips on how to maintain good oral hygiene practices.

What Are Seed Oils?

Seed oils are oils that are derived from seeds or nuts, and are commonly used in cooking, baking, and food processing. Common examples of seed oils include canola oil, soybean oil, sunflower oil, and safflower oil. These oils are high in omega-6 polyunsaturated fatty acids, which are often marketed healthy fats that can help reduce the risk of heart disease and other health issues.

However, the high levels of omega-6 fatty acids in many seed oils have been linked to inflammation and other health problems when consumed in excess. Seed oils are also a common source of phytic acid, which can bind to minerals in the body and inhibit their absorption. This can impact dental health by reducing the availability of important minerals such as calcium and phosphorus, which are essential for healthy teeth.

What is Tooth Decay?

Dental caries, or tooth decay, are caused by the demineralization of tooth enamel, the hard outer layer of teeth. This occurs when bacteria in the mouth metabolize sugars and other carbohydrates, producing acid as a byproduct that can dissolve the minerals in tooth enamel. Over time, this can lead to the formation of cavities, which can be painful and may require dental treatment.

Common risk factors for dental caries include poor oral hygiene, a diet high in sugar and carbohydrates, and a lack of fluoride in the diet. Regular brushing and flossing, along with routine dental checkups, can help prevent dental caries and other oral health issues. Treatment options for dental caries may include fillings, crowns, or other dental procedures, depending on the severity of the issue.

Seed Oils and The Oral Microbiome

Can seed oils give you cavities? Seed oils are a rich source of omega-6 polyunsaturated fatty acids, which can serve as a substrate for bacteria in oral biofilm. Certain types of bacteria in the oral cavity can metabolize these fatty acids, producing acid as a byproduct. This acid can lower the pH of the oral environment, creating an acidic environment that can demineralize tooth enamel, leading to tooth decay.

Elevated levels of omega-6 polyunsaturated fatty acids can heighten the permeability of oral biofilm, rendering it more vulnerable to acid erosion. Moreover, the imbalanced omega-6 to omega-3 ratio present in certain seed oils can foster systemic inflammation, exerting a range of detrimental effects on oral health, such as exacerbating gum disease.

The Role of Dioxygenases in Biofilm Formation and Dental Caries

The production of important lipids called oxylipins is a natural process that occurs in all forms of life. In animals, plants, algae, and fungi, the biological roles of oxylipins have been extensively studied, but their roles in bacteria remain largely unknown. A recent study in Nature Communciations investigated the effects of oxylipins produced by the bacterium Pseudomonas aeruginosa, which transforms omega-6 polyunsaturated fatty acids using diol synthase activity.

The study suggested that the oxygenation of omega-6 polyunsaturated fatty acids by dioxygenases may contribute to the formation of biofilms in the oral cavity, potentially increasing the risk of dental caries. Dental caries, also known as tooth decay, are a common oral health issue that occurs when bacteria in the mouth produce acid, typically as a byproduct of metabolizing carbohydrates, which can lead to the demineralization of tooth enamel and the development of cavities.

The study found that the oxylipins produced by P. aeruginosa had a significant impact on the bacterium’s motility and organization. While these oxylipins inhibited flagellum-driven motility, they upregulated type IV pilus-dependent twitching motility, which increased the bacterium’s ability to form microcolonies and form biofilms. These findings suggest that the prokaryotic oxylipins play an important role in the physiology and pathogenicity of bacteria.

In addition to their effects on bacterial organization and biofilm formation, the study also found that the oxylipins produced by P. aeruginosa promoted virulence in Drosophila flies and lettuce. This demonstrates a new way in which bacteria can cause infections, and highlights the importance of understanding the complex interactions between bacteria and their environments.

While the formation of biofilms is a normal process in the oral cavity, excess biofilm formation and accumulation can produce acid that can break down tooth enamel, leading to the development of dental caries. Seed oils, which are a rich source of omega-6 polyunsaturated fatty acids, may increase the availability of substrates for the oxygenation of these fatty acids and the subsequent formation of biofilms in the oral cavity. To reduce the risk of dental caries, it is important to consume seed oils in moderation as part of a balanced diet, practice good oral hygiene, and visit a dental professional regularly for checkups and cleanings.

Seed oils are a common source of oxylipins, which are a type of lipid molecule that are involved in a variety of biological processes in plants and animals, including inflammation and immune responses. The study of oxylipins is important because they can have both beneficial and detrimental effects on human health, depending on their type and amount. The experiment investigated the effect of oxylipins on the interaction between the bacteria GFP-expressing PAO1 and A549 cells. The study found that the presence of 10-HOME and 7,10-DiHOME (two types of oxylipins) affected the behavior of the bacteria, which suggests that oxylipins can play a role in the host-pathogen interaction.

Mineral Absorption and Tooth Decay

In addition to their potential effects on the oral microbiome, some seed oils may also affect mineral absorption and contribute to tooth decay. Minerals such as calcium, phosphorus, and magnesium are important for the mineralization of teeth and the maintenance of dental health. However, some seed oils may contain high levels of phytic acid, which can bind to minerals and inhibit their absorption.

Phytic acid is a naturally occurring compound found in many plant-based foods, including seeds, nuts, and grains. While it has some health benefits, such as antioxidant and anti-inflammatory effects, it can also interfere with mineral absorption and contribute to mineral deficiencies. In the context of dental health, phytic acid may reduce the availability of minerals that are important for tooth mineralization, leading to an increased risk of dental caries.

Healthy Alternatives to Seed Oils: Lowering Your Risk of Dental Caries

While seed oils are commonly used in the Western diet due to their affordability and versatility, there are alternative options that can be used in cooking and food preparation. For example, avocado oil, olive oil, and coconut oil are all healthy alternatives to seed oils that are low in omega-6 fatty acids and do not contain high levels of phytic acid. These oils are also rich in nutrients that are beneficial for dental health, such as vitamin E and antioxidants.

In addition, consuming whole foods that are low in phytic acid can help support dental health and reduce the risk of dental caries. Meat and dairy products, for example, are not a significant source of phytic acid and do not carry the same risk for dental caries as seed oils. In fact, research has long suggested that consuming dairy products may have a protective effect on dental health, due to their calcium and phosphorus content.

The Takeaway

In conclusion, the relationship between seed oils and tooth decay is complex and multifactorial. While there are no direct longitudinal studies linking seed oils to tooth decay, their potential effects on the oral microbiome and mineral absorption may contribute to its development.

The impact of seed oils on dental health is highly dependent on individual differences in oral microbiome and saliva composition, as well as other dietary and lifestyle factors. However, seed oils are a rich source of omega-6 polyunsaturated fatty acids, which can serve as a substrate for bacteria in oral biofilm, and some seed oils may also contain high levels of phytic acid, which can inhibit mineral absorption.
