What causes it Sensitive Teeth?
Tooth sensitivity occurs when the underlying layer of your teeth – the dentin – becomes exposed as a result of receding gum tissue (the protective blanket that covers the tooth roots). The roots, which are not covered by hard enamel, contain thousands of tiny tubules leading to the tooth’s never center (the pulp). These dentinal tubules (or channels) allow the stimuli – for example, the hot, cold, , touch or sweet food – to reach the nerve in your tooth, which results in the pain you feel.
Exposure of the dentine can occur due to a number of factors. Some of the more common reasons are:
- Gum disease, which can be the result in gum disease
- Acidic beverages that cause enamel erosion and dentine exposure
- Brushing with a very abrasive toothpaste, brushing incorrectly could result in a loss of enamel and or wear away the root surface
- Teeth grinding
- A chipped or fractured tooth may expose the dentine, or possible tooth decay
- In addition, some dental treatments can cause sensitivity such as; teeth whitening / professional dental cleanings / braces / crown placement / tooth restoration (Sensitivity caused by dental procedures is temporary, usually disappearing in 4 to 6 weeks)
What can I do about it?
The first step is to discover what the cause is. If the sensitivity is due to exposed dentine, there are a number of steps you can take, or we can take, to help reduce the sensitivity. These can include:
- Using a very soft bristle toothbrush
- Floss & Brushing correctly to help prevent abrasion of the enamel and recession of the gums and stop gum disease
- Using a toothpaste specially formulated to help reduce sensitivity
- In office desensitizing procedure if required
* In the end, whether you need us to perform an in office procedure or you require purchasing an over-the-counter products, the most important step is to set up a dental consultation so that is can be determined what is the cause of the tooth sensitivity and help you find a solution that will work.
Some of the active ingredients in over the counter toothpastes work by,
- stabilizes the nerve and protects it from firing. Nerve impulses to the brain is prevented and the resulting pain is stopped. This occurs over a period of weeks
- by blocking the exposed tubules within the dentinal tissue. This prevents the flow of the fluid with the tubules that would otherwise cause tooth pain.
- plugging and sealing dentine tubules, which helps block pain triggers to deliver instant and lasting relief.
