Teeth Sensitivity

Teeth sensitivity can make enjoying meals difficult and a number of problems can cause sensitivity:

 

1. Cracked tooth syndrome

2. Gum recession

3. Bruxism (teeth grinding)

4. Decay

 

1. Cracked Tooth Syndrome

 

A common problem in the posterior teeth (back teeth), hairline cracks in the tooth can cause hypersensitivity

to cold.

Teeth are often sensitive to biting hard and chewy food. Causes include large fillings, decay, bruxism, and

trauma. Diagnosis is usually conducted through tarns-illumination and a bite test. Treatment in many cases

 involves fitting a crown.

 

2. Gum Recession

 

Root exposure due to gum recession causes sensitivity to various temperatures.

In this case the gum line is below the normal level leaving the root which is yellowish in color exposed.

 

Causes of recession

 

• Periodontal disease

• Toothbrush abrasion

• Malocclusion (bad bite)

• Bruxism (teeth grinding)

• Frenum pull

• Poor oral hygiene

 

Treatment

 

• Desensitising toothpaste may work in reducing the sensitivity

• The application of desensitizing medication

• Severe recession may require a gingival graft to help replace lost gum tissue

 

3. Bruxism (teeth grinding)

 

Occlusal wear on the surface of the teeth causes cracks, and can make healthy teeth hypersensitive to cold.

 

Diagnosis

 

In addition to wear, other muscle symptoms such as tightness or soreness, headaches, earache and neck ache can be experienced.

 

Treatment

 

Removing any occlusal interference and using a night guard may be beneficial.

 

4. Decay (cavities)

 

Penetration of the decay deep into the tooth structure may cause hypersensitivity to cold.

 

Treatment

 

Sensitivity caused by decay cannot be reduced or resolved by using a tooth paste for sensitive teeth or desensitizing agent. Treatment requires filling the decayed tooth or fitting a crown. In the case of deep decay, root canal treatment may be required.
