Why are some of my teeth so sensitive?

Have you ever wondered why only some teeth become sensitive?
Here are some simple explanations:
 1.     ‘My dentist says I am brushing my teeth too hard’
It is impossible to brush certain teeth harder than others and cause sensitivity. The reason for this is that your bite is out and when you eat or bite you then put more pressure on certain teeth. This can be because of crooked teeth or an unhealthy jaw joint.
At Danny de Villiers Dentist in Weybridge, we use computerized bite analysis technology called T-Scan, to evaluate your bite and with minor adjustments the bite forces are evenly spread over all your teeth reducing or completely erasing the sensitivity.

No more need for special sensitive toothpastes that only treat the symptoms!
2.     ‘There are grooves in some teeth against the gum where the enamel has worn away’
These are called abfraction areas.This again is NOT brushing too hard. It is all about your bite that causes stress on the enamel which leads to enamel loss.
 3.     ‘My teeth are sensitive when I wake up in the morning’
You have most probably been grinding or clenching your teeth all night. This is caused by stress or because your teeth do not meet properly. Another reason is if your jaw joint is not working properly, as it has moved off the disc.
At Danny de Villiers Dentist in Weybridge, we can check the condition of your jaw joint with a JVA.
JVA is a computerised analysis of your jaw joints. The procedure is simple and painless. We place instruments like headphones over your jaw joints while you open and close your mouth several times. The computer records the vibrations and saves the information for us to analyse. This helps us to decide whether you need treatment and if so, what kind. It normally consists of wearing a hard splint on the lower teeth which will help you to stop grinding and protect / heal your jaw joint (TMJ)

4.     ‘Some of my teeth have small cracks or some teeth chip and break’
Once again….your bite is out or you are grinding your teeth!
 5.     ‘My molar tooth does not even have a filling, but it is very sensitive’
Your bite is out. You are putting a lot of pressure on this tooth all the time. This can cause nerve damage and then you might need root canal treatment in the future.
6.     ‘My tooth still hurts after root canal treatment’
It is either your bite that is out or grinding on the tooth that is still causing the pain. Have your bite checked.
The tooth could also have a crack running into the root.
The root canal treatment sometimes takes time to settle down, or not all if the nerve was removed.
7.     ‘My tooth has a large filling or crown and it hurts’
The nerve of the tooth is most probably affected and is dying (not healthy). The tooth will need a root canal treatment followed by a crown to protect it in the future.
8.     ‘My tooth hurts and is sensitive’
The tooth could have a cavity caused by decay. It needs to be filled, to prevent more damage in the future. See it as a warning sign!
