How Being Vegan Affects Your Teeth


There is no doubt that a plant-based diet is optimal for health. Omnivores and vegans alike
benefit from the nutrients present in plants.

But how does what we eat relate to our dental health?

Is a vegan diet better or worse for dental health?

Well, it depends. There are some concerns for oral health when one consumes a vegan diet. Here
are the main ones:

Vitamin B12 deficiency:
A vitamin B12 deficiency can lead to gum disease and tooth loss. Vegans should supplement with
adequate B12, as plants do not provide this important nutrient.

Lack of remineralizing foods:
Remineralization occurs when essential minerals that support hardened, healthy enamel are
resupplied to the tooth after loss caused by acid erosion. The best remineralizing foods include
cheese, meat, and milk, but nuts and leafy greens can also help.

Lack of important amino acids:
One example is the amino acid arginine, which is found in meat, poultry, fish, and dairy.
Arginine helps prevent cavities and gum disease by breaking down dental plaque. While
arginine is found in higher quantities in meat, vegan sources of arginine include pumpkin seeds,
peanuts, soybeans, lentils, and chickpeas.

Calcium concerns:
Your body needs enough calcium to support healthy teeth and gums. Vegans need to supplement
their diet with plenty of plant sources that contain calcium (almonds, leafy greens, beans,
etc.) as well as fortified vegan milks (almond, soy, rice, etc.).

Frequent snacking:
Continual snacking provides an environment for bacteria to thrive and attack your tooth’s
enamel. Vegans may be more prone to frequent snacking in an effort to meet their body’s need
for energy. You may find eating meals with a higher fat content helps you stay full for longer
periods of time.

More sugars/starches in the diet:
It can be easy as a vegan to eat a diet based on sweet/starchy foods like fruits and grains
(cereal, bread, pasta, crackers, rice, etc.), but the bacterias in your mouth that cause tooth decay
thrive on sugar. Make sure to round out your diet with non-sugary foods, such as tofu, nuts,
seeds, and plenty of vegetables.

If you’re a vegan, you already know you have to be mindful of certain key nutrients that you
may need to focus on or supplement in your diet. Keep this list in mind to ensure your dental
health is also in tip-top shape!
