You are enjoying a craftly delicious ice cream that you have just bought from the store. It looks so tasty and tempting, yet you want to savour the moment first. Then, you took the first bite. Alas! A sudden short and sharp pain struck your teeth and you feel irritated by it. Fortunately, the pain did not last long. Now, you take the second bite. Ouch!! The cycle repeats again.


The scenario is so obvious as many may have know that you possibly know what is wrong with that. In general, this condition is known as teeth sensitivity. In more scientific approach, this condition is called dentinal hypersensitivity.

Dentinal hypersensitivity is a short, sharp pain upon stimulation of cold or hot food and environment. It has several degree of pain which may range in between irritation all the way to shooting pain, depending on individuals. This condition affects most on young adults around the age of 20 to 40, with more on female. It affects roughly a third of all adults in Malaysia.

There are many possible causes for this condition. The most popular acceptance is that the dentine area of the tooth, which located inner of the outer layer enamel. Once the dentine has been exposed to the oral environment, there are direct connection between the nerves inside the pulp and the surrounding. Next, you must have a trigger. Most commonly hot, cold, sour and sugarly food; air pressure and physical biting force can cause the condition.


According to the famous Brannstrom's hydrodynamic theory, dentine area is not solid in composition, rather it contains numerous tunnels that connect right into the pulp nerves. These tunnels or also known as dentinal tubules contains liquid that travel into the nerve receptor. Once food or stimuli acts on the tooth surface, there will be disturbance on the liquid, a hydrodynamic flow and disturbance will trigger the nerves in it. Therefore you have pain.

The other causes can be due to excessive force inserted on the teeth when brushing. Brushing too hard can cause not only gum bleeding, but also erosion of the tooth surface. Decaying teeth (caries) or any root tooth expose can lead to the condition.

There are many ways to treat this condition, where most popularly, any dentist will recommend you Sensodyne. [visit the web here]
