After 5 minute the yellow colour of the TEETH becomes PEARL WHITE and shiny

Using eggshells to make yellow teeth “pearl white in 5 minutes” is a myth.
There is no scientific evidence that crushed eggshells can whiten teeth instantly — or at all.

Here’s the truth:

✅ What Eggshells Can Do

  • Eggshells contain calcium carbonate, which is similar to the mild abrasive found in some toothpastes.
  • When finely powdered, they can help polish teeth gently — but not whiten them dramatically.

❌ What Eggshells Cannot Do

  • They cannot remove deep stains.
  • They cannot change tooth color in 5 minutes.
  • They **cannot replace professional whitening or fluoride toothpaste.

⚠️ Risks of Using Eggshells

  • If not sterilized, eggshells may contain bacteria like Salmonella.
  • If the powder is too coarse, it can scratch enamel, making teeth more sensitive.
  • Overuse of abrasives can lead to enamel erosion, which makes teeth more yellow long-term.

✔️ Safe Ways to Improve Teeth Whitening

Here are methods that actually work:

1. Regular Brushing + Fluoride Toothpaste

Helps remove surface stains and strengthen enamel.

2. Whitening Toothpaste

Contains mild abrasives and hydrogen peroxide for gradual whitening.

3. Baking Soda (Occasionally)

Mix a pinch with water once or twice a week — NOT daily.

4. Professional Whitening

The only way to get dramatic whitening quickly.


If You Still Want to Use Eggshell Powder

Here’s the safe method (just for remineralizing, not whitening):

  1. Wash shells thoroughly.
  2. Boil for 10 minutes to kill bacteria.
  3. Dry completely.
  4. Grind into very fine powder.
  5. Mix ½ teaspoon into your toothpaste occasionally.

Again, this will not whiten teeth but may help with enamel minerals.
