If your tooth hurts when you bite down but your dentist says there is no cavity, you are not alone. This is a common situation, and it can be confusing.
The truth is that not all tooth pain is caused by decay. Pain with pressure often points to something deeper going on inside the tooth or how the tooth is functioning.
Common reasons this happens
One of the most common causes is a small crack in the tooth. These cracks are often too small to see on an x ray, but they can cause sharp pain when you bite because the pressure slightly shifts the tooth.
Another possibility is inflammation inside the tooth. The nerve can become irritated from things like past dental work, clenching, or trauma. Even without a cavity, this can make biting uncomfortable.
In some cases, there may be an infection starting at the tip of the root. This can create pressure that makes chewing painful.
It could also be something as simple as your bite being slightly off, especially if you recently had a filling or crown.
When to take it seriously
If the pain is consistent, getting worse, or paired with sensitivity to hot or cold, it is a good idea to have it evaluated. Pain when biting is often an early sign that something needs attention.
What to do next
The best next step is a proper evaluation to find the exact cause. Not every case needs a root canal, but identifying the source early can prevent things from getting worse.
