5. Sensitivity caused by a dental procedure
You might have recently had your crowns replaced. Maybe you have had your tooth extracted. Treatment of a root canal can also cause tooth sensitivity. If the discomfort keeps bothering you, please see the dentist – you may be suffering from infection.
6. Sensitivity caused by a cracked tooth
Cracked teeth can make you experience the bad sensations that you usually feel when you have sensitive teeth. Switching to another brand of toothpaste will hardly help you. See the dentist and ask if you have cracked or chipped teeth.
