Dental Pain

Pain is a very personal experience that can not be shared and is one of the major concerns of man. It is the most common symptom for consultation with the attending doctor.

We have said that is an experience that can not be shared, as identical pain stimuli applied to different individuals perceive it differently. We can not feel exactly the same as another person.
In the face and mouth are very sensitive to pain. Dentists have to differentiate the source of pain.

Here we go breakdown characteristics of various types of pain, focusing primarily on mucosal pain, dental pain and periodontal (which comes from the tissues that form the periodontium, which is the area surrounding the tooth).

Mucosal Pain
The mucosa of the oral cavity can be damaged by many factors such as alcohol, snuff, certain drugs administered orally or topically, dentin defects, restorations or ill-fitting dentures and so on., But may also be affected by local or systemic diseases an impact on the oral cavity, resulting in injuries that cause pain.

They are wounds that only hurt when a stimulus is applied. The site of injury and place of origin of the stimulus are the same. A further stimulus, the greater pain. Hence, the pain felt is proportional to stimulation. An injury that hurt when pressure is exerted on it at the site of injury, and the more pressure, feel more pain.

Let's make a classification of mucosal lesions that cause pain:

On one side are the infections, whether viral, fungal or bacterial infections. Some iatrogenic injuries can also cause pain, as is the case of injuries, also the chemical, physical. Squamous cell carcinoma (which is a tumor), recurrent canker mucocotáneas and certain diseases can be painful.

We found infectious lesions, which may be viral, bacterial and fungal infections. Today, the prevalence of oral infections is increasing, especially in patients with low immunity, being more common viral and bacterial fungal.

There are three groups of viruses that are capable of producing painful vesicular eruptions in the mucosa. Are herpes simplex, herpes varicella zoster and coxsackie. They remain latent in the body after infection, so that recurrences are common, ie, when they occur in people with certain virus called precipitating factors (such as stress), the symptoms reappear in disease.



The difference is that in the oral mucosa, where it first appears, yes there is a huge systemic involvement and local pain is one of the major problems, but recurrence is usually less important. In the cold sores, for example, will not be very painful recurrences (with exceptions).

We have said that bacterial infections are less common, but you have to mention the GUNA, acute necrotizing ulcerative gingivitis, their size. It is a destructive inflammatory process of the gums, causing a significant gingival pain. It is a type of moderate to severe pain, which is not caused by any external stimulus, but occurs spontaneously, and that is constant.

For fungal infections, ie yeast, we can ensure that the most common fungal infection of the upper digestive tract candidiasis. There are varieties of candidiasis, which causes pain being one of them is called antibiotic painful tongue (so named because it often appears with prolonged use of antibiotics).

Among iatrogenic causes, are the most common injuries that can be caused by biting, by mechanical irritation from poorly fitting dentures, etc...? It is a type of mild to moderate pain, and stop when the tissue heals. If the lesion becomes infected, the pain will increase.

Among the chemicals that cause pain, which produces the most frequently acetylsalicylic acid (aspirin) because contact with the mucosa, leading to chemical necrosis, and ulceration. Among physical agents would be thermal and electrical burns.

Neoplastic lesions of the mucosa, including squamous cell carcinoma only produce pain when lesions are very advanced and very intense.

Canker sores are indeed one of the most common injuries, and annoying during the first days. Loss of substance is the acute, painful, necrotic initial and recurrent. Although the lesion persists, it only hurts the first few days.

Among mucocutaneous diseases are lichen planus, with various clinical manifestations, but the only one that hurts the erosive type. If you are very large, produce severe pain that even hinder food intake. Pemphigus vulgaris produces a blister-like lesions, which will hurt if super infected.

Toothache
Dental pain is one of the most annoying pains suffered by humans, and is the most common reason that patients come to the dental clinic.

Dental pain sensation begins in the receptors in the pulp (which is endowed with nerve fibers) or dentine.

The cement and enamel, are insensible. When looking at the pain caused by such a decayed tooth, we see that it clearly shows the location of pain because the patient may feel referred to other areas. Dental pain has a great variability in their characteristics and intensity.

What may have toothache?

Dentinal pain.

It is a severe pain that lasts a few seconds, and occurs to stimuli externs. (These stimuli can be hot or cold beverages, fatty or sweet etc...) Natural stimuli such as extreme temperature changes can be significant in very sensitive teeth, but not necessarily indicate impaired dentin.

It's a pain that is very well located, the patient can not say which tooth hurts, and indicates an area and not a tooth as affected by pain. Almost always, the cause of this pain is tooth decay. A restoration in disrepair, the loss of a filling, etc. enamel abrasions. Are situations that can cause teeth to be more sensitive to pain?

Pulpal pain.

Pulp response to an external stimulus depends on the intensity of the stimulus is applied, and the state of it. The pulp undergoes changes with age and other physiological situations and so on. And is difficult to assess at each moment the state, so that the diagnosis of the type of pathological process that suffers the pulp is not easy.

The pain can range from mild to excruciating, can occur spontaneously without any external stimuli, or to thermal or chemical stimuli. It may be intermittent, with periods without pain, or continuous. We see therefore that is a kind of pain by a wide margin of variability.

Faced with a pain in the mouth area, the dentist usually thinks that this is a toothache, and possibly will be the first type of pain tends to discard.Pulpal pain that we find can be acute or chronic.

Acute pulpal pain can occur spontaneously, like a pinch short and intense to alter the individual while, or to various stimuli, giving the case to increase before the cold and heat, or increasing and decreasing heat from cold. It may be continuous or intermittent, momentary or maintained. Generally increases at bedtime because it increases blood pressure in the skull. Ceases when the tooth receives appropriate treatment or to spend some time, since after the acute inflammation of the pulp, it dies producing necrosis.

As in the dentinal pain is difficult to locate the tooth pain sufferer, especially when pain is mild.

The pulp chronic pain usually results in the continuity in time of acute injury. The pain can range from intense, as in an acute injury, to be simply a malaise that continues

Joint pain would occur twice, or when it has affected the periodontal acute inflammation of the pulp with periapical involvement (the final part of the tooth root) is rapid, or when the pulp is affected secondarily (in ascending order) from a pathological process that occurs initially in the periodontium.

We have said that practically the first thing for the dentist when the patient complains of a sore mouth is an injury or a possible cause that affects the tooth. The most common reason that causes pain is dental caries. Your dentist will look carious lesions.

To determine whether affected the periodontal patient to chew or refer pain to pressure, so the diagnosis easier.

When the patient shows great sensitivity to heat and electrical stimuli (those caused by the dentist), it generally consists of an acute pulpitis. If stimuli are light increasing the pain response in time, it will be a chronic condition.

Anesthetizing the tooth will see if that stops the pain was a toothache, the cause and we will seek appropriate treatment. As the cavities, which are usually the most common cause of toothache, progresses, we must make more drastic treatment for the tooth (such as a root canal the nerve-killing), so it is important to locate and treat pain as soon as possible.

Periodontal Pain
Periodontal pain is pain easier location of the tooth, as painful receptors are able to locate it fairly well stimulation, and the pain can be well provided the intensity. The diagnosis, as we have said before also tends to be easier than pulpal pain.

As a disease process can proceed either pulpal inflammation that eventually affects the periodontium, or involvement from outside the periodontium, (as in the case of gingivitis or periodontitis), it features vary Depending on the cause that has originated.

If it evolves into a chronic periodontal inflammation, pain ceases, but may recur in subsequent periods. Only there will be pain if the fistulae inflammatory lesion, ie forming a fistula that makes the purulent material (pus, etc.). Inflammation of the flow out.
