What are sensitive teeth?
Having sensitive teeth can mean anything from getting a mild twinge to having severe discomfort that continues for several hours. It sometimes feels like an electric shock on your teeth. Sensitivity is usually an early warning sign of more serious dental problems.
Why are my teeth sensitive?
The tooth is made of a strong outer coating of enamel and a softer inner layer of dentine. Dentine is very sensitive as it contains the nerve endings. Sensitivity arises when the dentine becomes exposed or when the enamel thins out. There are many reasons why happens:
- Tooth Abrasion – using a hard bristled toothbrush and brushing too hard can cause the enamel to wear away. This is particularly so at the necks of the teeth near the gum line as enamel is the thinnest at this point. Once enamel is worn and fresh dentine is exposed, it can be very sensitive.
- Tooth Erosion – Drinking too many fizzy drinks or excessive fruit juice can wear your teeth away due to the acid content contained within them. As the enamel dissolves away, the dentine exposes and causes sensitivity. See diet advice.
- Gum Recession – Brushing too hard can also cause your gums to be pushed back exposing the dentine on your roots and causing sensitivity. Remember root surfaces do not have any enamel.
- Gum Disease – As plaque and tartar build up, it causes gum disease. Advanced gum disease causes the underlying bone to break down and results in deep pocketing. This exposes the roots more causing sensitivity.
- Tooth Grinding (attrition) – Teeth clenching or grinding causes the top and bottom teeth to wear against each other. The enamel as a result will become worn and expose the dentine resulting in sensitivity.
- A Cracked Tooth or Filling – A crack can run from the biting surface of a tooth down towards the root. It can be as deep as the nerve sometimes and can be very painful.
What can I do to treat my sensitivity?
When your dentist diagnoses the cause of the sensitivity, you will be advised how best to treat it. Simple sensitivity can be cared for at home with de-sensitising toothpastes such as Sensodyne toothpaste. It can also be applied to the sensitive area and left overnight. Ask the dentist for further advice.
Is there anything I should avoid if I have sensitive teeth?
Hot, cold, sweet and acidic drinks can cause sensitivity, so you may want to avoid these. If cold water during brushing causes sensitivity, it may help to use warm water. It is very important you do not avoid brushing your teeth as this can cause further problems.
What if sensodyne toothpaste doesn’t help?
At Synergy, we offer a range of treatments to tackle sensitivity. This can range from simple fluoride application and sealants, to root fillings.
How can prevent sensitive teeth?
- By brushing your teeth twice daily, with a soft bristled toothbrush or an electric toothbrush.
- Change your manual toothbrush or the head of your toothbrush every 2-3 months.
- Try to avoid brushing your teeth side to side and up and down with a lot of force.
- Try to reduce your sugary foods and fizzy drinks and limit them only at mealtimes.
- If you grind your teeth, talk to your dentist. A night guard may be made to help you.
- Visit your dentist every 6-12 months.
