Why is it that when one has a tooth extracted, the gap left feels a kilometre wide.

Response:

When a tooth is extracted, the sensation of a wide gap can be attributed to several factors:

1. Physical Space: The extracted tooth creates an actual void in the dental arch, making it feel larger than it is.
2. Swelling and Inflammation: The extraction can cause swelling in the surrounding tissues, which enhances the feeling of a larger gap.
3. Nerve Sensation: The nerves in the area may be hypersensitive following the procedure, leading to increased awareness of the space.
4. Psychological Factors: The mind often exaggerates sensations after dental work. The awareness of losing a tooth can amplify the perception of the gap.
5. Adjustment Period: It can take time for the mouth and tongue to adjust, making the area feel more pronounced initially.

Overall, it’s a combination of physical changes and sensory perception that contributes to that feeling.

So there I have it.
