Oral health: The Women vs. Men Saliva Secret
Our saliva is often underestimated, but it is invaluable when it comes to oral health. Research conducted by PhD student Andrei Prodan shows the differences in the composition of saliva between men and women, which has potentially important implications for our oral health.
Saliva plays a crucial role in protecting against tooth decay
Saliva is more than just moisture in the mouth. It acts as an invisible hero, and its composition appears to play a crucial role in protecting against tooth decay, also known as caries.
The influence of saliva composition on oral health
Our mouth harbours a complex ecosystem, a dynamic interplay between microorganisms and ‘host factors’. Prodan found that the composition of proteins, peptides and metabolites in saliva affects this delicate balance. Intriguingly, he distinguished different subgroups of people based on their saliva composition, with striking differences between men and women.
Prodan’s research shows that women have a slight disadvantage – their saliva has a lower pH and less buffering capacity, two factors that may protect teeth less effectively. A lower pH in saliva composition can affect oral health, particularly in relation to the risk of tooth decay (caries) because it strengthens bacterial plaque. pH indicates acidity, and in the case of saliva, a low pH is an indication of acidity.
Here are some examples on which a lower pH can affect:
Tooth enamel erosion: Acid can erode tooth enamel. A lower pH in saliva increases acidity in the mouth, which can contribute to the erosion of the protective enamel layer on your teeth.
Caries development: A more acidic environment in the mouth favours the growth of bacteria that cause tooth decay. These bacteria thrive better in an acidic environment, which can lead to plaque formation and eventually caries development.
Buffering capacity: Lower buffering capacity means saliva is less able to neutralise fluctuations in acidity. This makes the mouth less resilient against acid attacks after eating or drinking acidic foods.
It is important to note that lower salivary pH is not the only factor affecting oral health. Other factors, such as oral hygiene, dietary habits and general health, also play a role. Good oral care, healthy lifestyle, including a balanced diet and regular dental checkups, remains essential for maintaining good oral health.
Tips to counter the effects of low salivary pH
Whether you are a woman or you suffer from low pH in your saliva anyway, we have listed below some ways you can reduce the impact of lower pH on your oral health:
The right oral care products: The presence of active oxygen and xylitol in blue®m products, such as in the toothpaste, mouthwash and oral foam, ensure that you continue to produce sufficient saliva. In addition, our products are pH neutral.
Limit acidic foods and drinks: Reduce consumption of acidic foods and drinks, such as soft drinks, fruit juices, acidic sweets and citrus fruits. If you consume them, rinse your mouth with water afterwards to neutralise the acidity.
Drink water regularly: Water washes away food particles, helps cleanse the mouth and neutralises acidity. It is especially beneficial after eating acidic foods or drinks.
Chew sugar-free gum: Chewing sugar-free gum, with xylitol stimulates saliva production, which can help neutralise acids and restore a healthy pH level in the mouth.
Oral hygiene: Maintain good oral hygiene by brushing and flossing regularly. This helps remove plaque and prevents the build-up of harmful bacteria.
If you notice that you have problems with low pH in your saliva composition and this is impacting your oral health, it is advisable to consult a dentist. A dentist can create a personalised treatment plan and make recommendations specific to your situation.
