What are the causes of sensitive teeth?

Millions of people are affected by pain when eating hot or cold foods or cold air. This sensitivity is caused by receding gums, or loss of cement, which is a thin layer of calcified tissue that acts as a protective covering around the tooth root. When gums recede, the root and nerve of the tooth is exposed. Nerves react to cold, heat and pressure cause pain. In the end, as the gums recede or worn enamel on the teeth, a sensitive tooth is more obvious.

Enamel loss

There are several reasons for the loss of enamel. Acids in the mouth can sometimes cause erosion. They can come from food and drinks, such as sugary drinks sweet or bitter (usually sprinkled with powdered bitter, sour), carbonated and lemons. They can also be present acid reflux or acid left behind after vomiting.

Even brushing your teeth incorrectly can cause the problem. The friction of brushing too hard can erode the enamel over time, and to brush back and forth can wear cement. The friction of teeth grinding is another form of enamel is lost.


Decalcification or excessive plaque on the teeth, causing cavities, Decalcification can come from improper care of the mouth, or the constant contact of the brackets in orthodontic appliances. Over time, decalcification causes cavities.

One of the first signs of decay is the appearance of white spots on tooth enamel. Cavity patients complain of toothache, fever, a bad taste in the mouth and chills and often have bad breath. When the enamel is violated, the teeth become sensitive to pressure, heat and cold.

Tooth abscess

If a tooth infection is treated, you can fill with pus and become an abscess. Typically, abscesses are caused by cavities and poor dental hygiene. The infection causes inflammation and irritation of the gums, allowing the affected nerves.

Whitening products

Many people notice tooth sensitivity after using teeth whitening products. Typically these contain hydrogen peroxide or car amide peroxide can cause irritation and soft tissue. This usually occurs in the early stages of treatment and disappears after treatment has stopped.

Gum disease

Gingivitis and periodontitis cause the gums away from the teeth. This makes the root and nerves exposed, causing tooth sensitivity. If left untreated, pus pockets form and gums, bones and tissues are destroyed.
