Sensitive teeth may indicate other oral problems

Sensitive teeth may indicate other oral problems

My grandmother always said: "Those who drink soup do not drink cold water!" The idea that thermal shock can ruin my teeth seems logical, but if my grandmother had known Petit Gateau would certainly make an exception. Popular belief ... Wisdom of the elders ... Is it legend? Myth or Truth?

It is true that enamel conducts heat faster than dentin. In this way, when the teeth come in contact with low temperatures, the enamel undergoes a contraction faster than the dentine, resulting in a thermal stress. If the change in temperature is too high, cracks may appear on the enamel.

A common practice among children and adolescents is to bite and chew ice stone. This is not recommended because in addition to exposing the tooth to low temperature, there is a risk of fracture of the tooth. The tooth structure is very friable and can break when it crushes very hard substances.

The tooth enamel is extremely mineralized and almost impermeable. However, if this protection is removed and the dentine is exposed, the tooth may be sensitive. Most people have a low sensitivity to ice cream, but it is not normal to be sensitive to the usual temperature of food and liquids, or water when brushing teeth. If this is occurring the reasons should be investigated.

When teeth are sensitive it is a sign that something is not right ... It is time to ask your dentist why this is happening. The possible causes for tooth sensitivity are many and of course the treatment depends on the cause - so using paste for sensitive teeth does not always solve. Here are some causes for sensitivity to cold:

Gingival Retraction

Retraction of the gingiva exposes an area of ​​the tooth that is not enamel coated, so this region, the "neck" of the tooth, is sensitive. > Caries

When the caries reaches the dentin it causes pain. Sometimes the pain is small, but it is always an alert to be considered, because its evolution can be rapid.

Restoration fractured or infiltrated

The image of the fracture or infiltration of a restoration is not always visible and often pain is the first manifestation. In this case the restoration needs to be redone.

Occlusal trauma

Occurs when the occlusal balance is not good, when a new restoration is "a little bit" high or when we bite something harder "by surprise". You know that turkey we suddenly get when we eat popcorn? Excessive consumption of soft drinks, reflux of gastric juices (gastritis, anorexia nervosa, bulimia), use of illicit drugs (methamphetamine), can lead to many traumas.

Enamel demineralization due to acid action

cause erosion of dental enamel.

It is known that citric acid present in normal or dietary refrigerants and energetics is known to have a high potential for causing enamel demineralization. The acid pH causes demineralization of the enamel, but in a balanced diet, the saliva is able to neutralize the pH and allow remineralization. Thus, the demineralization process is compensated by constant remineralization. Therefore, it is recommended not to brush your teeth immediately after the meal. It is best to rinse your mouth with water immediately after eating and wait half an hour before you brush your teeth.

Tooth Whitening

The use of bleaching agents without the guidance and supervision of the dentist can have undesirable consequences. Research has shown that whitening products, depending on application time and concentration, can penetrate the pulp chamber (the pulp site, popularly known as the canal), especially in restored teeth.Laboratory studies suggest that dental restoration may facilitate the entry of bleaching agents into the pulp chamber. If bleaching is done without discretion, it can cause sensitivity and irreversible damage to the pulp.

These are just a few examples, but note that in all cases pain is always a warning sign. Our body always warns us and it is our responsibility to seek help.

9 Common Doubts About Deep Vein Thrombosis

Thrombus, a term that gives rise to deep venous thrombosis (DVT), is the name of the blood clot that forms inside the veins of lower limbs, such as the legs, blocking blood circulation .
