in May 26, 2025

Toothpaste is essential in daily oral care routines, but have you ever wondered what happens if we accidentally swallow it? While most of the people spit out toothpaste after brushing, sometimes a little may end up being swallowed.

It’s important to know whether this can be harmful to your health. Let’s explore the side effects of swallowing toothpaste and what you can do if it happens.

 

What Is Toothpaste Made Of?

Toothpaste contains several active and inactive ingredients that work together to clean teeth. These include:

  1. Fluoride: A key ingredient for preventing tooth decay.
  2. Abrasive: Help remove plaque and stains.
  3. Humectants: Keeps the toothpaste moist.
  4. Flavouring Agents: Provide minty or fruity taste.
  5. Detergents: Create the foaming action.

While these components are generally safe when used as intended, they can pose risks if swallowed in large quantities. Eating toothpaste is dangerous if consumed in excess, especially by children.


Is Eating Toothpaste Bad for You?

A question always lingers in our minds: Is eating toothpaste bad for you? The answer depends on the amount and frequency. There are few side effects of swallowing toothpaste, but the small amounts swallowed during brushing are harmless. Children are particularly vulnerable because they might mistake flavoured toothpaste for candy.

While fluoride helps protect against tooth decay, excessive ingestion can lead to fluoride toxicity. Learn more about the pros and cons of flouride for teeth here.

The question becomes critical when ingestion is habitual or involves large quantities.


Side Effects of Swallowing Toothpaste

The side effects of swallowing toothpaste depend on the amount ingested. Eating toothpaste side effects include:

  1. Nausea and Vomiting: High fluoride intake can upset the stomach and cause digestive issues.
  2. Fluorosis: Long-term ingestion during childhood can lead to white spots on teeth.
  3. Abdominal Pain: High fluoride levels in the body can cause cramping.
  4. Serious Toxicity: Large amounts can result in low calcium, muscle spasms, and in extreme cases seizures.

While swallowing in pea-sized amounts occasionally is not harmful, eating toothpaste side effects can become dangerous if consumption is habitual or involves large quantities. Eating toothpaste is dangerous; it can cause more serious health issues, such as kidney damage or bone problems due to fluoride buildup.

What to Do If Someone Swallows Toothpaste

If someone accidentally swallows toothpaste, they must-

  • Assess the quantity: A small amount likely doesn’t require medical attention.
  • Drink Water: This helps dilute the fluoride
  • Monitor Symptoms: Watch for nausea, vomiting, or abdominal pain.
  • Seek Medical Help: For significant ingestion, especially in children, contact a healthcare professional or poison control centre immediately.


Preventing Toothpaste Ingestion in Children

Children are prone to swallowing toothpaste because they may find it tasty or may not fully understand the risks. Here are some tips to prevent toothpaste ingestion:

Use a pea-sized amount: Limit the toothpaste applied to their brush.

Supervise Brushing: Ensure children spit out the excess toothpaste and rinse properly

Choose Age-Appropriate Toothpaste: Use non-fluoridated toothpaste or special toothpastes for children for gentler formulations

Educate: Teach children the importance of spitting out toothpaste instead of swallowing it. Learn how to teach your children to brush their teeth correctly.

Eating toothpaste can be dangerous for children, so proper guidance is crucial.
