How The Keto Diet Affects Oral Health

added on: March 25, 2020

Starting a new diet can be both exciting and difficult, and there are many different types of diets to choose from. One of the most common diets is the Keto Diet, and its followers often find weight loss success. But as with all diets, the Keto Diet does come with potential negative side effects. There’s one in particular that concerns your dentist in Lyndhurst — bad breath. 

How The Keto Diet Works

The Keto Diet helps people lose weight by forcing the body to burn fat instead of glucose. Dieters essentially cut their intake of carbohydrates, and the sugars that come along with them, and increase their consumption of high-fat foods. This causes the body to enter ketosis, which is when the body burns fat instead of glucose. The result is often successful weight loss. But there’s another thing that happens as a result of ketosis — the byproduct of three ketones called acetoacetate, beta-hydroxybutyrate, and acetone. The acetone is what may cause Keto Dieters to experience bad breath. 

Acetone & Bad Breath

Even though our bodies produce acetone, it can’t be used to store energy –  so our bodies release it through either urination or the lungs. Acetone has an unpleasant odor, so when it’s passed through the lungs, the smell can be transferred to our breath. Bad breath from the Keto Diet doesn’t necessarily happen to everyone, but those it does affect can find resolution by brushing and flossing daily and by seeing their dentist in Lyndhurst at least twice a year. Additionally, those who are on the Keto Diet long-term may become “keto-adapted,” which means the bad breath will go away. 

Keto Diet Benefits

Besides helping people lose weight, the Keto Diet may also benefit oral health. Carbohydrates contain a lot of sugar, and it’s no surprise that your dentist in Lyndhurst isn’t a big fan of sugar. But by eating fewer carbs, we’re also cutting back on the amount of sugar our teeth are exposed to, reducing the risk of decay and cavities. You see, when we eat sugary foods (including carbs), the bacteria in our mouths feed on the sugar and release an acidic byproduct. This acid can cause tooth enamel to weaken and puts teeth at greater risk for decay. But when we limit sugary foods as Keto Dieters do, we can protect our teeth from these acids. In fact, some research shows that decreasing foods with a lot of carbs can lower the likelihood of cavities and even gum disease by 50% or more. 

Before You Start, Ask

As with any change to your eating habits, you should talk to your doctor prior to starting the Keto Diet or any diet. What works well for one person may not be appropriate for someone else, so make sure to discuss your plans with your physician. Additionally, we would also recommend talking with your dentist. The truth is, what we eat affects our oral health just as much as it affects our overall health. Your dentist can give you advice as to what you should expect with your oral health on a new diet. So before you start any diet, ask your medical team what would be best for you.
