The dough may be crumbling because it is too dry and lacks enough moisture to hold together.

Another reason could be overmixing the dough, which can cause the gluten to develop too much, resulting in a crumbly texture. **

The tooth may be crumbling due to tooth decay, which is caused by bacteria in the mouth producing acids that erode the tooth enamel. Poor oral hygiene, such as infrequent brushing and flossing, can also contribute to the breakdown of the tooth structure.

It is important to address the issue promptly by visiting a dentist to prevent further damage and potential tooth loss. **

One possibility is that the concealer has dried out, either because it is old or because the cap was not closed tightly, allowing air to dry it out.

Finally, the concealer may be crumbling because it was applied over a product that was not properly set or dried, causing it to mix and create a crumbly texture. **
