Want to know about:
- Why cold water relieves a toothache?
- Why does my toothache go away with cold water?
- Why does holding water in my mouth help my toothache?
This is pretty common in dentistry. In dentistry, it is termed strangulation theory. Unfortunately, what it often means is you have a nerve that is infected and died.
Here is a brief explanation of:
Why is cold water the only thing that makes my toothache go away?
There are 2-main nerve fibers in a tooth:
- A-delta fibers
- C fibers
Definition and difference between them
- A-delta fibers are what sense is cold, sharp shooting pain.
- C fibers are what sense is dull throbbing pain.
One key difference between A-delta fibers and C-fibers is A-delta fibers carries a sharp, sudden, prick type of pain in the body. It sends a quick pain message to the brain to prevent it. However, C-fibers carry a lingering kind of pain like aching and burning.
The A-delta fibers have large-diameter cell bodies and conduct a fast action potential. The C-fibers have small-diameter cell bodies and carry out slow action potential.
A-delta fibers respond to the senses like touching or brushing. C-fibers respond to the senses like warm or cold.
When a nerve dies inside of a tooth over time, pressure begins to develop in the tooth. For instance, think of if you have a water bottle in your car that gets very hot, then that water bottle builds up the pressure. When that pressure builds up in your tooth, it compresses those A-fibers and due to that reason, you begin to have lots of pain.
So, when the heat makes your tooth hurt and cold water relieves your pain, it implies that the nerve inside your tooth is dead. Unfortunately, the cure is to have a root canal treatment done and get your nerve tissue removed. If you can’t afford the root canal cost, have your tooth extracted.
