Keto Diet and Oral Health: The Facts Behind Keto Breath


If you’ve tried the keto diet, you might be familiar with “keto breath”—an odor that’s less-than-flattering. It happens because ketosis produces ketones, which escape through your breath.


  • What it smells like: Fruity or metallic.
  • Why it matters: It’s a sign your body is burning fat but can also leave a lingering smell.



Pro Tips to Tackle Keto Breath:


  • Stay hydrated to flush away bacteria.
  • Use sugar-free gum or mints to mask odors.
  • Invest in a quality toothbrush. (Discover why an electric toothbrush could be your best friend​.)


Acidic Saliva and Tooth Enamel


Here’s another keto surprise: ketosis can make your saliva more acidic, weakening enamel over time. Dry mouth is also common, increasing your risk of cavities.


How to Protect Your Teeth on Keto:


  • Balance your meals with leafy greens and non-acidic veggies.
  • Use fluoride toothpaste to strengthen enamel.
  • Learn additional tricks to banish bad breath once and for all​.


Veganism: A Nutritional Balancing Act for Your Smile


Veganism comes with great benefits for overall health, but it’s not always smooth sailing for your teeth. Eliminating animal products can mean missing out on key nutrients like vitamin B12, calcium, and omega-3 fatty acids.


What Happens When You’re Deficient?


  • Vitamin B12: A lack of this nutrient can lead to mouth sores and gum inflammation.
  • Calcium: Your jaw and teeth need it to stay strong—without enough, you risk tooth decay and bone loss.


How to Fill the Gaps


  • Choose fortified plant-based milks and supplements.
  • Rinse your mouth after eating acidic or sticky foods like citrus fruits or dried fruit.
  • Discover more about healthy but surprising food risks​.


Other Popular Diets: Paleo and Intermittent Fasting


The Paleo Diet: Is it Too Much of a Good Thing?


The paleo diet emphasizes whole, unprocessed foods, which is great—but watch out for acidic fruits and high-meat consumption. These can wear down enamel over time.


Smart Paleo Tips:


  • Include non-acidic veggies like cucumber and celery.
  • Stay hydrated to neutralize acids.


Intermittent Fasting: A Hidden Risk


Going hours without food reduces saliva production, which can lead to bad breath and increased cavity risks.


Pro Tips for Fasting:


  • Hydrate constantly to keep your mouth moist.
  • Avoid sugary drinks; they can worsen dry mouth.


Easy Oral Health Tips for Every Diet


No matter what diet you follow, keeping your teeth healthy is all about balance and care. Try these simple tips to stay ahead:


  • Hydrate Like a Pro: Water is your best defense against dry mouth and bacteria.
  • Snack Smarter: Ditch sticky, sugary snacks for crunchy veggies like carrots or celery.
  • Fill Nutritional Gaps: If your diet skips essential nutrients like calcium, consider supplements.
  • Keep Up with the Basics: Brush twice a day, floss regularly, and schedule your dental visits.
