Dreams about broken teeth, especially canines, can often symbolize feelings of vulnerability, loss of power, or concerns about self-image. The fact that you didn't notice the broken tooth for a while might suggest that there are aspects of your life or your self-perception that you are unaware of, or perhaps you've been ignoring something important.

Your mom’s laughter in the dream could indicate a sense of dismissal or a light-hearted attitude toward a situation that you might find serious. It may reflect your feelings about how others perceive your problems or insecurities.

Consider what the broken tooth represents to you personally. Are there areas in your life where you feel powerless or insecure? Are there relationships where you feel your concerns are not taken seriously? Reflecting on these questions can provide deeper insights into your emotional state and how to address any underlying issues.
