piece of teeth fall off by cookie bite does it mean i have allergy to cookies?

If a piece of your tooth fell off while biting into a cookie, it is not necessarily an indication of an allergy to cookies. Instead, it could suggest that your tooth had underlying issues, such as decay or weakness, which might not have been apparent before. Biting into something hard or crunchy can sometimes dislodge a weakened tooth. However, if you experience pain, swelling, or other unusual symptoms in your mouth after eating cookies, it could be worth consulting a dentist to determine the cause. Allergies typically manifest with symptoms like hives, swelling, or gastrointestinal distress, not dental issues. If you're concerned about allergies, consider speaking with a healthcare professional for further evaluation.
