Why Does Spinach Make Teeth Feel Weird

Eating spinach makes teeth feel weird due to the high levels of oxalic acid in the vegetable. Spinach is considered a superfood that contains a vast array of nutrients ranging from vitamins c, a, and k to lutein and folate.

It is no wonder why many people incorporate it into their daily meals. However, some people who consume raw spinach notice an odd feeling on their teeth. This sensation is known as spinach teeth, and it occurs due to the high oxalic acid content in the vegetable.

Oxalic acid can bind to calcium in saliva and form crystals that remain on the teeth, resulting in a gritty, chalky texture that feels weird. Despite experiencing spinach teeth, it is still crucial to consume spinach for its numerous health benefits. In this article, we’ll explore the causes of spinach teeth and how to prevent it from happening.

The Science Behind Oxalic Acid And Teeth Sensitivity

Spinach is a great source of fiber and numerous health benefits, but it contains oxalic acid which can lead to teeth sensitivity. The acid in spinach can bind with calcium in the body, preventing it from being absorbed properly. This can affect tooth enamel, causing sensitivity and discomfort.

Oxalic acid can actually form crystals in the kidneys, leading to kidney stones, which is why those with kidney problems are often advised to avoid spinach. However, the amount of oxalic acid in spinach is lower than in some other vegetables like beets.

To reduce the effect of oxalic acid on tooth enamel, it’s recommended to consume spinach with calcium-rich foods like dairy products. Additionally, consuming spinach raw can help since cooking can lead to increased oxalic acid concentration.

Spinach: An Oxalic Acid Culprit

Spinach has been touted as a superfood, but its oxalic acid content can be a concern. Oxalic acid is known to bind to calcium and form crystals that can cause an uncomfortable sensation in the teeth. Spinach’s oxalic acid content is higher than most other leafy greens, such as kale and collard greens.

However, it’s still a nutritious food that can be included in a balanced diet, as long as it’s consumed in moderation. The amount of spinach that’s safe to eat varies from person to person, but generally, it’s recommended to limit consumption to 1-2 cups per day.

By adding other calcium-rich foods, like cheese or yogurt, to a spinach-based meal, the oxalic acid can be neutralized, reducing the risk of teeth sensitivity.

Preparing Spinach To Reduce Tooth Sensitivity

Spinach is a healthy and nutritious vegetable, but some people experience an awkward sensation in their teeth when eating it. This is due to the high oxalic acid content found in spinach, which can cause tooth sensitivity. However, there are ways to reduce the oxalic acid content in spinach and prepare it in a way that is less likely to cause discomfort.

Frozen spinach is a better option for reducing sensitivity as the freezing process breaks down some of the oxalic acid. Cooking spinach can also help by reducing the oxalic acid content. Try blanching or sautéing spinach instead of eating it raw.

Pairing spinach with calcium-rich foods, such as cheese or yogurt, may also help reduce tooth sensitivity. Don’t let tooth sensitivity keep you from enjoying the benefits of spinach in your diet.

Other Foods That Can Cause Teeth Sensitivity

Spinach is not the only food that can cause awkward teeth sensation. Other foods that contain oxalic acid, such as rhubarb, beets, and sweet potatoes, can also lead to teeth sensitivity. However, the amount of oxalic acid in these foods is lower than that in spinach, making them less likely to affect your teeth.

Foods that are too hot or too acidic, like citrus fruits or soda, can also cause sensitivity. To consume these foods without harming your teeth, try eating them with a straw or rinsing your mouth with water afterwards. Overall, be mindful of what you eat and how it affects your dental health.

Home Remedies For Tooth Sensitivity

Tooth sensitivity is a discomfort caused by hot or cold beverages, acidic foods, and the exposure of teeth roots. Fortunately, there are many home remedies that can help reduce sensitivity. One of the simplest remedies is to use a toothpaste specially made for sensitive teeth.

Using a fluoride mouthwash may also help. For those who prefer natural remedies, oil pulling and baking soda are viable options. However, if the sensitivity is severe and ongoing, it’s important to visit a dentist. They can assess and diagnose the issue and recommend proper treatments.

Whether it’s a home remedy or professional treatment, it’s crucial to address tooth sensitivity early on to prevent further discomfort.
