Hypersensitive teeth (dentine hypersensitivity) is a pathological condition in which the exposed dentin (dental tissue that lies between the enamel surface of the tooth and cement-centered dental pulp), which makes your teeth sensitive to mechanical, osmotic, chemical or thermal stimuli.
Stimulation leads to displacement of dentine fluid inside and outside (through dentine channels that extend from the pulp through the dentine), leading to transmission of stimulated nerve endings in the pulp and subsequent pain. Dentin hypersensitivity is one of the most common symptoms that patients complain when visiting the dentist.
What causes hypersensitive teeth?
Causes of dentin hypersensitivity are many: loss of enamel due to the effects of mastication and parafunctional power (chewing) or due to erosion caused by acidic foods. On the other hand, the withdrawal of the gums due to periodontal disease or inadequate technique of brushing, stripping of root causes and the loss of a thin layer of cement that protects the root. In these cases, there is exposure to the dentine channels for simulation, such as mastication, entering hot and cold liquids and food. Exposed parts of the teeth lead to pain that can cause problems. For example, people with sensitive teeth will be very difficult to drink cold drinks, eat chocolate or ice cream with a spoon.
By dental aspects, agents commonly used can be divided into three main groups:
Anti Inflammatory agents Resources that promote closure of dentin tubules (usually based on oxalate, sodium ions …)Assets influence depolarisation of nerve endings in the pulp. It is believed that the laser energy is absorbed by photochemical transformation photothermic, photoelectric and photomechanic effects, especially in compromised tissue cells. In this way the lasers generate stimulating, anti-inflammatory, analgesic and antiedematostic effects. In this way the patient feels pain reduction and termination.
When is the right time to visit the dentist?
If your teeth are too sensitive (react to hot and cold) for more than a week is best to visit a dentist on how to assess the degree of hypersensitivity. Before you take matters into your own hands, it is best to seek expert advice on the correct diagnosis of the extent of the damage. Pain is not a specific symptom and occurs in a number of diseases. For this reason it is best to seek professional advice. You should be sure when pain occurs, whether caused by some simulation and how long it lasts.
Can present commercial products actually reduce hypersensitivity?
Toothpaste, whose effect is to reduce the sensitivity, usually includes some of the medications that protect the exposed dentin tubules. However, this paste must be used continuously for a long period of time (minimum one month) in order to observe initial results.
Can a dentist help?
There are a number of therapeutic procedures for the treatment of dentin hypersensitivity, including the use of drugs in dental practice, the application of laser therapy and prescription drugs for application at home.
How is the patient going to prevent relapse after complete surgical interventions?
Listen carefully to the advice given from your dentist. He will advise on the use of drugs, and to avoid further irritation should be omitted acidic drinks. These patients should avoid toothpaste with abrasive properties (polish teeth). Some ingredients of the paste for teeth whitening or for removing pigmentation with enamel as sodium pyrophosphate, may result in hypersensitivity. Also, the dentist may suggest that you change your technique of brushing and applying protective gels.
