Causes of tooth sensitivity to heat and cold

Investigating the causes of tooth sensitivity to heat and cold

Tooth sensitivity is the result of tooth damage and tooth dentin. The layer on the dentin is lost due to reasons such as receding gums or tooth enamel damage, and as a result, the dentin is exposed to hot and cold materials.. Usually, a combination of different factors causes the teeth to become sensitive, although which factor plays a more important role depends on the specific conditions of each patient.. In this article from Dr. Hossein Borjian's website The best gum surgeon in Isfahan We will examine the causes of tooth sensitivity to heat and cold.

Improper brushing method

Brushing hard or using a hard toothbrush causes tooth wear Gingival analysis will be. In this case, mechanical damage is caused to the teeth and gums due to repeated injuries. This damage is usually the result of using a hard toothbrush. Instead of a hard toothbrush, use a soft or medium toothbrush and brush carefully and apply gentle pressure. Grinding hard on the teeth does nothing but damage them and does not help to clean the teeth..

Abrasive toothpastes such as whitening toothpastes exacerbate this problem. Additionally, as more enamel wears away and wears away, the tooth becomes darker and yellower.. Enamel is the white part of the tooth, and when it wears away, the yellow dentin is better seen under the enamel.. Some people notice the yellowing of their teeth and without knowing the reason, they brush harder and make the teeth yellow unintentionally.. Antiallergic toothpastes have a special composition that reduces tooth wear.

Acid corrosion

In corrosion with acid, it is a chemical reaction that dissolves tooth enamel. The enamel at the gum line is thinner than other places, and for this reason, it wears completely at this point first, and as a result, the underlying dentin becomes visible.. Then the worn area becomes wider as a result of contact with the acid and eventually a small hole or dent is created in the tooth.. Acid corrosion can affect all surfaces of teeth; Sometimes the occlusal surface, or the surface of the tooth with which we chew, is perforated as a result of acid contact..

Acids can be edible and enter the oral environment as a result of eating acidic foods and drinks such as fruit juice, carbonated drinks and citrus fruits.. Acid abrasion and corrosion can be the result of stomach upsets, this problem is common among patients with gastroesophageal reflux or heartburn.. Asthma patients who use the spray in an inappropriate way may also suffer this type of dental damage..

Loss of covering over the nerve

The nerve is usually not in contact with foreign substances, but if the sensitivity, especially the sensitivity to cold, is severe, you just feel that the nerve is in contact with the cold substance without any protection.. In addition to sensitivity to cold and heat, there is a possibility of sensitivity to touch, brushing, sweets, salty foods and even air.. For example, breathing on a cold day causes toothache. Most patients who are worried about the sensitivity of their teeth to cold avoid eating ice cream or cold drinks and wash their teeth with lukewarm water instead of cold water after brushing..

Tooth dentin has a large number of tiny canals, called tubules, which extend from the nerve and pulp of the tooth to the dentin.. These tubules contain water; It is thought that the movement of water inside these tubules is the cause of pain. Cold and hot materials cause the water to expand and the pain starts as a result of nerve stimulation. The movement of air and salt in the water also aggravates the pain. The intensity of the pain can be much more intense than the actual injury and that is why this reaction is an exaggerated reaction and is called hypersensitivity.. In this condition, the tooth becomes overly sensitive to normal stimuli.

Grinding teeth and grinding teeth

Grinding the teeth and pressing the teeth together causes wear of the tooth enamel. Grinding the teeth causes the teeth to rub at the place of contact with each other; This type of wear is called attrition. The teeth do not touch each other during normal speaking and chewing, but only briefly overlap each other.. But the teeth rub against each other when grinding. Grinding teeth sometimes occurs during the day, for example when enduring stress or concentrating. Sometimes teeth grinding occurs during the night and while sleeping. Bending of the teeth under pressure causes the tooth collar to break; This type of wear is called abfraction. Teeth grinding is usually an unconscious habit.

teeth whitening

Teeth whitening can also cause tooth sensitivity, so it is best to have your teeth bleached by a dentist so that the dentist can assess the risk of tooth sensitivity.. Other causes of teeth sensitivity include cracked teeth, Tooth Decay and fracture or shedding of tooth restorative material. For this reason, you should report the symptoms carefully to the dentist.

Cracked teeth

Small cracks develop over time as a result of expansion and contraction of teeth in hot and cold temperatures.. These cracks cause the nerves to come into contact with cold materials, and as a result, the tooth becomes sensitive to cold. Look closely at your teeth for fine lines, which can be signs of microscopic cracks.

Declining gums

Constant sensitivity of the teeth to cold or heat is a good reason to visit the dentist. Carefully examine your gum line to see if the gums have receded from the teeth.. The decay of the gums makes it easier for the feeling of heat and cold to be transmitted to the nerves of the teeth.

Tooth decay or gum disease

If a cold-sensitive tooth hurts when you eat or drink a cold substance, you may be in the early stages of tooth decay or gum disease.. Accumulation of plaque on the teeth and gums causes tooth sensitivity to cold and ultimately promotes gum disease and tooth decay.. 80 The percentage of tooth sensitivity starts at the gum line, so to eliminate the main cause of tooth sensitivity, it is necessary to use the right toothpaste for the gums..
