Tooth sensitivity is a condition in which teeth become more sensitive to hot or cold temperature stimuli and external forces. The most common causes are receding gums and enamel wear. Treating sensitive teeth is not difficult but needs to be done properly.1. What is the definition of sensitive teeth?
Teeth are composed of 3 parts from the outside to the inside: enamel, dentin and pulp. Normally, enamel covers dentin, but if the enamel layer is worn away, it will reduce its ability to protect dentin. At that time, the nerve endings in the pulp will be directly affected by hot or cold temperatures from drinks and foods. Such nerve stimulation creates pain in the root of the tooth, also known as tooth sensitivity.
Sensitive teeth, is a common dental problem that is common in young and middle-aged people and can progress over time.
2. Causes of sensitive teeth
Common causes of teeth become sensitive such as:
Improper oral hygiene: using a toothbrush that is too hard, brushing too hard horizontally to wear down the neck, damage the gums and cause exposure root. Sour foods: foods with high acid content such as toads, mangoes, oranges, tangerines, tomatoes or tea... can cause enamel erosion. Teeth grinding: strong and continuous grinding forces the chewing surface of the teeth to wear down. Mechanical impact: chewing on hard foods such as hard candy or chewing on ice or being hit by an accident can lead to cracked teeth. When the tooth is cracked, the nerve endings will be stimulated, causing the tooth to be painful. In addition, tooth cracks are also a place for bacteria that cause infection. Cavities: deep holes in the tooth, if deep into the pulp, expose the nerve endings in the tooth pulp, causing the tooth to be sensitive. Periodontitis: is an infection of the gums that causes destruction of the bone and supporting structures of the teeth, exposing the root surface of the teeth.

Use a toothpaste containing fluoride to strengthen minerals to help strengthen the tooth structure, prevent tooth decay, and prevent sensitive teeth.

Avoid grinding your teeth while sleeping, use a tooth guard at night to limit this situation. Fluoride gel or anti-sensitivity gel to apply to sensitive teeth. Dental intervention is the way to treat sensitive teeth if the above measures do not work. Treatments include fillings, full or partial crowns, glue to cracked or decayed teeth, gum grafts to protect the root of the tooth to reduce sensitivity, and endodontic treatment (pulp removal).
