Neck of the tooth does matter

The neck of the tooth, is the part closest to the gum. It is also referred to as the cervical third. Any change in the color and the texture in the cervical third of the tooth means there is an actual lesion.
What are the causes of these lesion, is it only about caries?!

Lesions of the cervical third can be caused by:
1. Abrasion.
Yes, brushing your teeth using the wrong technique, or in an aggressive way can cause wearing of the enamel surface especially where it has minimal thickness in the cervical third.
2. Bruxism and malocclusion.
Bad habits as bruxism (clinching) cause an increase in the occlusal forces, which become concentrated in the cervical region causing flat saucer shaped lesion.
Malocclusion cause the same thing, the only difference is that, the changed direction of the occlusal forces that become concentrated at on area, causing breaking of the cervical enamel prisms and lead to V-shaped lesion.
3. Erosion.
Drinking too much juice that contain acid, as lemon or orange juice, or suffering from gastric reflux can dissolve the enamel on the cervical third, causing flat saucer shaped lesions.
4. Caries.
Bad oral hygiene indicates the presence of dental plaque, that leads to demineralization of the enamel causing first white spot lesion then caries.
Dental plaque also leads to inflammation of the gingiva, followed by periodontitis that leads to gingival recession which increase the risk of root caries.

Symptoms:
The patient usually complains of sensitivity with sweets, hot, cold or even pressure.
>What to do to these lesion?
It depends on the symptoms and extent of damage.
First, the underlying cause needs to be diagnosed and managed.
If there are no symptoms and they are not cosmetically detrimental, then they are left alone.
If they cause sensitivity, then the sensivity needs to be managed.
They are indicated for restoration, if they are cosmetically important, or they are too big which means exposure of the nerve is eminent, or they are too sensitive to be treated with the conservative methods

Conclusion:

The Neck of the tooth can be influenced by what you eat, any bad habits, and oral hygiene. Pay attention to the neck of teeth.
