About Sensitive Teeth
Tooth sensitivity is very common and it has been estimated that over half the population suffer from sensitive teeth.
Most people notice their tooth sensitivity when they eat or drink something hot or cold. But you might also notice tooth sensitivity when you go outside on a really cold day and a blast of cold air hits your teeth or something touches them.
The good news is that sensitivity doesn't usually mean that you need complicated or uncomfortable dental treatment. However, sensitivity is a warning sign that you may need to improve your oral health and should not be ignored.
Why do I get sensitive teeth?
A normal, healthy tooth has a hard, protective cover called enamel. This shields the inside of the tooth, which is softer and contains nerves and a blood supply.
If the enamel becomes thinned, these microscopic tubules beneath the enamel become exposed. Once exposed, the tubules can transmit stimuli like hot and cold to the nerves causing that sudden sensitive feeling.
What are the main causes of Sensitivity?
The 3 main causes of tooth sensitivity are:
- Acid Erosion: Common food and drinks can wear enamel away.
- Sugary Foods: Sugary foods encourage the growth of bacterial colonies. Bacteria beneath the gums causes gum recession which means sensitive areas are exposed.
- Incorrect brushing technique: Over brushing or brushing too hard can wear away tooth enamel.
