What is the toothpaste pregnancy test?

For women who are eager to find out if they are pregnant, waiting to get their hands on a store-bought pregnancy testing kit might prove to be too long. [1] In this case, there are many do-it-yourself hacks these days that can help you confirm or rule out a pregnancy much before you get around to buying a home pregnancy testing kit.[2] The toothpaste pregnancy test is one such DIY pregnancy hack that has become extremely popular these days. The key facts about the toothpaste pregnancy test are listed below.

The do-it-yourself toothpaste pregnancy test can be done very easily at home. It involves adding a couple of drops of urine to a little bit of toothpaste. The chemical reaction that results will tell you whether you are pregnant or not. You are supposed to use plain white toothpaste and not the fancy gel-types. Once you put a few drops of urine onto the toothpaste, stir the mixture and watch for any color change or foaming.

How does the Toothpaste Pregnancy Test Work?

The concept behind the toothpaste pregnancy test is quite simple, and the results are also derived relatively quickly. Neither does it require too much preparation on your part. The only things you need for this test is a tube of white toothpaste, a sample of your urine, and a container in which you can mix the toothpaste and your urine.

Here's how you can perform the toothpaste pregnancy test:

●       Take a regular white toothpaste and squeeze out a generous amount into an empty container or cup.

●       Urinate in a separate cup.

●       Now slowly pour some of the urine samples into the cup or container that holds the toothpaste. Stir the mixture.

●       Check to see the urine-toothpaste mixture for a reaction. 

Supporters of this toothpaste pregnancy test are convinced that when you combine urine with toothpaste, it will lead to a chemical reaction. Either a change in color or the mixture will start fizzing. This change is an indication that you are pregnant and the pregnancy test is positive. [3]

If you are not pregnant, then the body will not be producing the pregnancy hormone, and therefore the toothpaste and urine will not create any type of chemical reaction. There will be no fizzing, and the toothpaste will also not change its color.

However, it is essential to realize that this is not an accurate way of predicting pregnancy. If you try this method and believe the result is positive, then it is necessary to take the conventional pregnancy test or visit a doctor to confirm the pregnancy with a blood test. [4]

Toothpaste pregnancy test theory

The theory behind the Toothpaste Pregnancy Test

Women who have used the toothpaste pregnancy test firmly believe that the ingredients present in toothpaste react chemically with the pregnancy hormones in the urine. The chemical reaction that ensues is supposed to cause the toothpaste to foam or change color when it comes in contact with urine. However, this chemical reaction might just be because of the acidity of urine. 

Urine is known to be acidic, having a pH of 6.0 to 7.5. [5] Different brands of toothpaste are also known to have different levels of acidity. For example, a 2011 study tested the acidity levels of seven whitening tubes of toothpaste, and the results showed that the acidity ranged from being very basic to very acidic. [6] 

The theory behind the toothpaste pregnancy test results is based on the pH levels of the toothpaste and urine involved. Nevertheless, the toothpaste pregnancy test is completely inaccurate, and there is no evidence that this test can detect pregnancy. The standard store-bought home pregnancy tests work by looking for the presence of the pregnancy hormone known as hCG or the human chorionic gonadotropin hormone. This hormone is released by the placenta of a pregnant woman as soon as the fertilized egg implants in the uterus lining.[7] This hormone is also believed to cause many of the common symptoms of early pregnancy, including nausea and vomiting, or morning sickness. [8]

Apart from the placenta cells, hCG can be produced by several other parts of the body, including:

●       Pituitary gland

●       Colon

●       Liver

●       Certain tumors

There is no way that toothpaste will be able to detect the presence of the hCG hormone, and there is no research that indicates that the toothpaste pregnancy test is effective. [9]

Toothpaste pregnancy test accuracy

Is the Toothpaste Pregnancy Test Accurate?

No, the toothpaste pregnancy test is not at all accurate, and neither is it a reliable method of confirming a pregnancy. No evidence suggests that toothpaste can detect the presence of hCG in a woman's urine. Any type of fizzing you notice only occurs because of the toothpaste reacting to the acid present in urine.

Urine naturally contains uric acid, which will be present in the urine of anybody, regardless of whether they are female or male, pregnant or not. At the same time, one of the key ingredients present in toothpaste is calcium carbonate. When calcium carbonate is combined with an acid, it can sometimes cause a fizzy or foamy reaction. 

This reaction is why if a toothpaste pregnancy test causes fizzing, instead of taking it as an indication of pregnancy, it is necessary to understand that it is simply a chemical reaction between the toothpaste and the uric acid present in urine. Both men and non-pregnant women could get the same results from doing a toothpaste pregnancy test. On the other hand, if the pregnancy test does not fizz, then it might just be because the person has less uric acid in their urine.

Summary

If you have reason to believe that you might be pregnant, there are many other more accurate ways of testing for pregnancy, with home pregnancy tests being one of the fastest and cheapest ways to confirm. These tests can be purchased from any drugstore, grocery store, or even online these days. They are designed to detect the presence of hCG, the pregnancy hormone. Remember that the sooner you confirm the pregnancy, the better it is for you and your baby's health as you will be able to start the required prenatal care at the earliest. Proper prenatal care is vital for a healthy pregnancy. Trusting the results of a DIY toothpaste pregnancy test is not a great idea and will not give you an accurate result.
