Common Causes of Tooth Sensitivity

tooth sensitivity

Tooth sensitivity can develop at any time, causing anything from a slight painful twinge to serious discomfort.

Sensitive teeth aren’t just a real pain to deal with, they can also be a sign of a more serious problem. Here, we look at some of the most common causes of tooth sensitivity and how to treat it.

What causes tooth sensitivity?

Many things can trigger tooth sensitivity. If you want to eliminate the issue, you need to first understand what’s causing it. Let’s look at some of the main causes…

Dental erosion

Over time, the enamel on the teeth can get worn away. As it does, the teeth lose their protective coating, leading to sensitivity. Acidic food and drink are typically to blame, though erosion also occurs naturally over time.

As you age, the gums can start to recede, sometimes revealing the root of the tooth. As there is no enamel to protect the roots, they can become extremely sensitive.

Gum disease

A buildup of tartar and plaque can lead to receding gums, and potentially damage the bones that support the teeth. When left untreated, gum disease can cause potentially serious health issues as well as tooth sensitivity.

Brushing too hard

You might think that brushing your teeth harder will help to keep them squeaky clean. However, what it actually does is wear away the tooth’s enamel. Brushing from side to side can also cause this problem, resulting in tooth sensitivity.

Teeth whitening

Now, teeth whitening is becoming a popular choice to remove stains from teeth and achieve a brighter smile. However, many treatments, especially those bought without the advice of a dentist, can leave the gums feeling sensitive and sore. This is mostly down to levels of bleach used in some teeth whitening procedures. At CK Dental, we can ensure that you receive the safest and most effective teeth whitening treatment.

You can opt for safer, gentler teeth whitening options such as the new *Pola Light teeth whitening kit. It provides additional hydration during the whitening process, minimising the risk of sensitivity.

Tooth grinding

If you frequently clench or grind your teeth, it can result in sensitive teeth. Over time, the grinding and clenching motions wear down the enamel.

Treatments include wearing a mouth guard for a period to prevent you from grinding the teeth.

Cracked teeth

Another potential cause of tooth sensitivity is cracked teeth. If the tooth becomes damaged or cracked, it may reveal the nerves of the teeth, causing severe discomfort.

When should I seek help for tooth sensitivity?

If you are experiencing sensitivity because of a broken or cracked tooth, you will need to seek help from your dentist. You may need a filling, or a crown fitted.

Any tooth sensitivity that carries on for longer than a few weeks should be looked into. There are many treatment options available, and your dentist will be able to help you identify the cause.
