Causes of tooth sensitivity

Dentist Shreveport

Tooth sensitivity is a very common problem. Teeth may be sensitive to temperature (heat and/or cold), sweets, or pressure. It’s uncomfortable, may make it difficult to eat and drink normally, and can even be painful. Does tooth sensitivity indicate an underlying serious problem? Is there anything that you can do to reduce the sensitivity?

What causes teeth to be sensitive?

The outer layer of the tooth, the hard enamel, does not contain nerves. In general, things that affect this layer will not lead to pain. The layer underneath of this is called the dentin, and the deeper layer is called the pulp. The nerve of the tooth is inside of the pulp, and small nerve endings project outward into tiny tubes within the dentin.

When the enamel is damaged or thinned, then these nerve endings can be stimulated more easily. This is when teeth begin to feel sensitive. There are several different possible causes of tooth sensitivity, including:

• Aging (the enamel naturally thins as we age)
• Dental caries (cavities)
• A cracked tooth
• A prior filling that has become loose or has been damaged
• Teeth whitening (especially if too much product was used, or for too long)
• Frequent consumption of acidic or sugary foods or beverages
• Receding gums (this exposes the lower part of the tooth, where the dentin is more exposed)

Some of these issues will tend to lead to sensitivity in a particular tooth, while others will cause more general sensitivity.

What can be done to address tooth sensitivity?

The treatment for tooth sensitivity depends on what the cause of the symptom is. This is why the first step is always to bring up the problem with your dentist. For example, if the sensitivity is caused by a cavity or a cracked tooth, then treatment of this issue with a filling or a crown should take care of the problem. A damaged filling can be replaced.

If gum recession is the cause of tooth sensitivity, then treating this issue can help. Receding gums are often caused by gum disease, so extra professional cleanings and antimicrobial treatments may help. In some cases, a gum graft may be used. In this procedure, tissue is moved from other parts of the mouth and transferred into the areas where gum tissue has been lost.

If the problem causing sensitivity can’t be remedied directly (for example, thinning enamel caused by aging), then there are other possible solutions that may help. There are toothpastes and mouthwashes that can help to reduce sensitivity. Some of these can be acquired over the counter, and there are also stronger versions that require a prescription from a dentist.

If you’re having tooth sensitivity, then you should discuss it with a dentist. An exam will determine whether you have an oral health issue that should be addressed, such as a cavity or a cracked tooth. If so, it’s important that this be taken care of as soon as possible, because these types of problems can become more serious if left untreated.
