Causes of tooth sensitivity

Solutions for tooth sensitivity

If you experience sudden tooth sensitivity symptoms, there is no choice but to feel flustered, because tooth sensitivity is a representative symptom of cavities.

If you rush to just any dental clinic in fear, you may end up becoming the target of excessive treatment at an unethical clinic.

This is because people tend to think that the cause of tooth sensitivity is only cavities.

By learning about the various reasons for tooth sensitivity, we hope you receive appropriate treatment at an honest dental clinic.

If sudden tooth sensitivity symptoms appear, there are two representative reasons for tooth sensitivity that you can consider:

a tooth problem

a gum problem

  • Eating irritating foods

One cause of temporary sudden tooth sensitivity symptoms is eating irritating foods. In particular, cold foods with a low temperature or sour foods with a high acidity can transmit stimulation all the way to the nerves inside the pulp.

  • Everyday habits

A cause of tooth sensitivity symptoms that may appear temporarily is everyday habits. If you grind your teeth while sleeping, bite on tough or hard foods, or brush your teeth too forcefully, your teeth may wear down and become sensitive.

  • Damage to the teeth

If tooth sensitivity symptoms continue, one reason for tooth sensitivity is damage to the teeth. If there are cavities, cervical abrasion, or cracks in the teeth, the position of the tooth nerve and the position of the external area where stimulation is applied become closer, which can cause tooth sensitivity.

If tooth sensitivity symptoms still appear even after resolving the tooth-related reasons for sudden tooth sensitivity, there is periodontal disease as a cause of tooth sensitivity due to gum problems.

If tartar is left untreated for a long time and accumulates between the teeth and gums, inflammation will occur in the gums. This is periodontal disease.

If periodontal disease is not treated, the gum bone gradually dissolves and the tooth roots become exposed, causing tooth sensitivity.

Tooth sensitivity caused by tooth problems can be solved by:

• Avoiding irritating foods

• Treating teeth grinding

• Not biting on tough or hard foods

• Brushing gently and softly

• Treating cavities

• Treating cracks in the teeth with resin or G.I

Tooth sensitivity due to gum problems can be resolved with:

• Regular scaling

• Periodontal curettage

• Gum surgery

As such, the causes and reasons for sudden tooth sensitivity vary, and because the solution differs depending on the cause, appropriate treatment at an honest dental clinic is necessary.

Otherwise, due to excessive treatment at some unethical dental clinics, all tooth sensitivity symptoms may be overdiagnosed as cavities, and unnecessary root canal treatment and crown treatment may be performed.

Or, due to poor treatment at some inadequate dental clinics, the symptoms of tooth sensitivity may be misdiagnosed as another cause, and unnecessary other treatments may be performed.

At Gangnam Station and Sinnonhyeon Station, I hope you can resolve tooth sensitivity at Gangnam Sero Dental Clinic, a trustworthy clinic without excessive treatment, with highly skilled medical staff, and a safe dental clinic without poor treatment.
