As your gums start to pull back and expose the surface under the gums, you may suffer from sensitivity. This soft layer makes up your tooth’s root consisting of small tubes leading to your tooth nerve. So, when you eat something too cold, hot, or sweet, these tubes send a signal to your nerve, causing pain. There are multiple reasons why your gums can pull back to reveal the dentin, including:
- Wear and tear from grinding your teeth, brushing too hard, or using the wrong type of toothbrush.
- Tooth decay at the gum line.
- Inflammation of the gums due to Gingivitis.
- Teeth become more sensitive between the ages of 25 and 30.
- Chipped, broken, or damaged teeth.
- Recent dental work – but it could be temporary. Talk to your dentist.
- There is too much plaque buildup on the surface of the root.
