Should you eat after brushing your teeth?

No, you should not eat after brushing your teeth at night.

You should brush your teeth after your last meal before going to bed at night to keep your teeth healthy.

This is because eating after you brush your teeth allows food particles to sit on your teeth while you're sleeping. This process leads to:

  • Plaque buildup

  • Halitosis (bad breath)

  • Dental caries (cavities)

Otherwise, if you are brushing in the morning, wait 10-15 minutes to have your first meal.

This article will explain everything you need to know about how your diet affects your oral health and when to brush your teeth.

What is plaque?

Plaque is an organized film of bacteria that develops on your teeth over time. It's sticky and difficult to remove once formed.

Once formed, plaque can:

  • Harden into tartar

  • Spread and develop into your gums

  • Leave your tooth enamel in a weakened state

Brushing your teeth twice per day helps disrupt bacteria in your mouth and prevent plaque buildup.

What causes plaque buildup?

Plaque forms when certain ingredients in your diet feed the bacteria in your mouth and cause them to multiply.

These bacteria mostly feed on acidic food and sugar. When food particles sit on your teeth for longer periods of time, they promote bad bacteria organizing into plaque, that sticky film coating your enamel.

This is why it is extremely important to keep a healthy diet and not skip brushing your teeth before bed.

Who is most at risk for plaque buildup?

Certain people are more susceptible to plaque buildup than others, such as those who:

  • Smoke cigarettes

  • Consume a diet high in sugary and acidic food (ex. carbohydrates and orange juice)

  • Take certain medications known to cause dry mouth

Brushing your teeth before you go to sleep is essential to reduce tooth decay and risk of disease.

What are the side effects of plaque buildup?

Over time, plaque buildup can cause many different oral care concerns, including:
  • Cavities
  • Halitosis
  • Gum disease
  • Weakened tooth structure

Further, dental plaque in your mouth has been shown to be correlated with heart disease.

How to Prevent Plaque with Your Diet

Even if you're brushing twice per day, your diet greatly influences your oral health. Some of the best ways to protect your are simply to drink water and watch what you eat.

Worst Foods for Your Teeth

The worst foods for your teeth are those high in sugar and acid, and some are worse than others:

  • Juices

  • Alcoholic drinks

  • Carbonated soft drinks

  • Any foods high in citric acids (like lemon juice)

Acidic food will feed the bad bacteria in your mouth, while an alcoholic drink will dry out your mouth and reduce saliva production.

Both of these processes, and more, contribute to plaque.

Best Foods for Your Teeth

The best foods for your teeth are ones that promote saliva production and strengthen your enamel. Some good examples include:

  • Black and green tea

  • Fish (ex. wild salmon, sardines)

  • Vegetables (ex. garlic, spinach)

  • Dairy (ex. eggs, raw milk)

  • Fermented foods (ex. kefir, sauerkraut)

As a bonus, not only will they protect your teeth, but they will fight bad breath as well!

All of these foods fit into a nutritious diet that will promote not just oral health but your overall health as well.

Can I eat after brushing my teeth?

No, it's best not to start eating after brushing teeth at night. The American Dental Association recommends people avoid brushing if you're planning to eat again before going to sleep.

Most people, if not all, will benefit from brushing first thing in the morning and last thing at night.

Is it good to eat after brushing your teeth?

Eating after brushing contributes to plaque buildup and other oral health concerns.

To avoid promoting tooth decay and gum disease, you should not eat after brushing your teeth at night.

Should you brush your teeth in the morning?

Yes, you should brush your teeth in the morning.

In the mornings, brushing your teeth should be the first step you take to avoid swallowing bacteria while eating breakfast.

That being said, you should avoid brushing immediately before your first meal. Instead, wait to eat for at least ten to thirty minutes after brushing to protect your enamel.

Should your brush your teeth at night?

Yes, you should brush your teeth at night. This beneficial process will:

  • Prevent cavities

  • Fight bad breath

  • Reduce plaque forming on your teeth

  • Get rid of food particles and harmful bacteria

For best results, spend two minutes carefully brushing your teeth with a soft bristled toothbrush and nano hydroxyapatite toothpaste twice per day.

When should I eat after brushing my teeth?

After brushing your teeth in the morning, wait to eat for ten to thirty minutes.

This is because your enamel is in a weakened state after brushing and needs time to return to full strength.

Should I brush my teeth again after eating at night?

Yes, you should brush your teeth again after eating at night to prevent plaque formation and potential tooth decay. By brushing your teeth before bed, you'll easily be able to remove plaque and food particles that otherwise contribute to tooth decay

However, you should be aware that brushing immediately after eating acidic foods or sugar foods at night can potentially damage your enamel as the acids weaken your enamel temporarily. Therefore, we recommend waiting 20-30 minutes after eating  to brush your teeth before. By waiting, you'll allow your saliva to neutralize the acids and your enamel to reharden before you begin brushing.

Further, in addition to brushing with nano hydroxyapatite toothpaste to prevent and reverse tooth decay, we also recommend flossing with expandable floss, using tongue cleansers, and using alcohol free mouthwash.

How to eat Turmeric without Staining Teeth

Avoid consuming turmeric with acidic foods like tomatoes and lemons and citrus as the acidity helps the stain set into your enamel.

If you do eat turmeric, brush your teeth right away to avoid the stain getting locked in. With teeth, one stain can get trapped under another stain, and making everything harder to remove.

Think of teeth staining like spilling wine on a cotton t shirt. The sooner you get it out, the better!

Can you eat after oil pulling?

Yes, you can eat after oil pulling.

Oil pulling does not remove plaque, nor does it properly clean your teeth. Through the oil pulling process, you're not physically removing the biofilm on your tooth enamel surfaces.

That being said, oil pulling is being studied as an effective method to improve your oral health by dislodging bacteria from under your gums.

What can you eat after brushing your teeth at night?

Nothing, you should not eat anything after brushing your teeth at night. Eating or drinking after brushing can diminish the effectiveness of the toothpaste and rinse away the protective ingredients like nano hydroxyapatite left on your teeth.

However, if you do feel the need to have a snack or beverage after brushing, opt for something light and non-acidic, such as a small serving of plain yogurt. These options are less likely to interfere with the benefits of your brushing and can help maintain a cleaner, healthy mouth overnight.

Conclusion: can you eat after brushing teeth?

You should not eat after you've brushed your teeth at night, and you should wait ten to thirty minutes to eat after brushing your teeth in the morning.

Additionally, you should avoid eating a diet high in sugars and acid as these can have harmful effects on your mouth.

By abiding by these heuristics, you will keep your tooth enamel healthy and prevent oral disease.
