Does Brushing Teeth Break a Fast? The Truth for Women

Ladies, if you’re like the estimated 16% of women who practice intermittent fasting, you may have wondered - does brushing teeth break a fast? It’s a valid concern, especially when you’re striving to reap all the benefits intermittent fasting can offer, such as an average 7% decrease in visceral fat after 6 months according to one study. But fear not! We’re about to dive deep into the truth about oral hygiene and fasting so you can brush away those worries.

What Breaks a Fast?

Before we tackle the tooth-brushing dilemma, let’s quickly review what constitutes breaking a fast. The basic rules of intermittent fasting dictate that you should avoid consuming any calories or digestible ingredients during your fasting window.

Why? Because ingesting just 50 calories can increase insulin levels by up to 51% and negate the metabolic benefits of fasting.

Brushing Teeth with Water: Safe for Fasting

Here’s the good news, ladies: brushing your teeth with plain water does not break your fast! Water has zero calories and no digestible components, so it won’t kick your body out of that coveted fasted state. Plus, it contains no ingredients that could spike your insulin levels - critical when over 25% of U.S. women have prediabetes.

Toothpaste: A Potential Fast-Breaker

Now, here’s where things get tricky. Most conventional toothpastes contain 0.3-1.1% sweeteners like saccharin or sucralose, flavorings, and thickening agents – all of which could potentially provide up to 2-5 calories per brushing or trigger an insulin response. And we know even small calorie amounts under 50 can impact fasting.

However, not all toothpastes are equal. Around 5% of the market is natural, fluoride-free pastes without controversial ingredients. If formulated well, these could allow brushing while fasting for some women. But check labels carefully - the average woman’s paste has over 20 ingredients.

Tips for Brushing During a Fast

To play it safe, our recommendation is to simply brush with water, especially during longer fasting periods over 18 hours when benefits like reduced oxidative stress and inflammation spike.

But we get it - up to 57% of women report concerns over bad breath. In that case, try a pea-sized dab of an approved natural paste. Just be minimal, as amounts over 1 gram could potentially sneak in calories.

And remember, good oral care is crucial regardless of fasting. Women who practice intermittent fasting long-term need to remain vigilant, as studies show a temporary increase in tooth erosion and gum inflammation during the first few months.

The Bottom Line

There you have it, ladies! Brushing your teeth with plain water is a-okay during your intermittent fasts. As for toothpaste? It’s a bit riskier, but opting for minimal amounts of natural, scrutinized varieties without sweeteners or controversial agents could work for some. At the end of the day, understanding the rules is key to enjoying the up to 83% greater weight loss and 14% decrease in LDL cholesterol levels seen in women who fast consistently. So keep brushing carefully and fasting confidently!

FAQ about IF and Brushing Teeth

Q: Does brushing teeth with water break an intermittent fast?

A: No, brushing your teeth with plain water does not break an intermittent fast. Water has zero calories and no digestible ingredients, so it won’t trigger an insulin response or provide energy during your fasted state.

Q: Can I use toothpaste while intermittent fasting?

A: Most regular toothpastes contain small amounts of sweeteners, flavorings, and other potentially caloric ingredients. Using too much toothpaste could potentially provide enough calories to technically “break” your fast. However, a pea-sized amount of an all-natural, unsweetened toothpaste is unlikely to have a significant impact.

Q: What about mouthwash during a fast - is that allowed?

A: Like toothpaste, many mouthwash brands contain sweeteners or other caloric ingredients. Stick to an unsweetened, alcohol-free mouthwash with no added sugars or artificial sweeteners if you want to use it during a fast. Plain water works great as a mouth rinse too.

Q: I’m doing an extended fast - should I still brush my teeth?

A: Yes, continuing your regular oral hygiene routine is recommended even during prolonged fasts. However, you may want to brush with water only and avoid toothpaste to eliminate any caloric intake. Consult your dentist if you have specific concerns about tooth brushing during an extended fast.

Q: Can bad breath from fasting affect my oral health?

A: Potential bad breath is a common side effect of fasting due to ketone production. However, chronic dry mouth from fasting could increase risks of tooth decay and gum disease over time if oral hygiene isn’t maintained. Be sure to stay hydrated and consider approved oral care products during your fasts.
