Orofacial Pain – Odontogenic Pain (pain coming from the tooth)

Table of Material

Orofacial discomfort can be explained as any discomfort occurring in the facial skin and mouth, like the nasal area, ear, eyesight and throat. It impacts thousands of people every day all over the world, and can become the effect of a selection of disorders and illnesses. Orofacial discomfort can be split into odontogenic and nonodontogenic discomfort.

Odontogena discomfort is any discomfort in the facial skin and mouth due to teeth (Gr. Odous = teeth), while neodontogena discomfort any discomfort in that region which is not really of dental source (lat. dens = teeth). Even though definition of dental pain is clear and simple, its interpretation and classification vary from author to author. Some authors odontogenic pain shared by only the dentin and pulp pain, while some that divide add more and periodontal discomfort, periapical discomfort and reflected discomfort, based on which area of the teeth or the related tissues causes.

What exactly are the sources of dental discomfort?

Elements that adversely influence the integrity, physiology and normal functioning teeth can cause odontogenic pain. These factors may take action on a tooth and the pulp or supporting system tooth and periapical tissue. Factors that affect the tooth and the pulp and leading to odontogenic discomfort could be bacterial, distressing, iatrogenic, chemical substance and idiopathic character. They can trigger inflammation from the pulp (short-term and long lasting) or its necrosis and withering aside.

The microorganisms which are found in oral caries will be the most common bacterial causes of changes in the dental pulp, and thus dental pain. Acute (crown and root fractures, loosening and tooth avulsion) and chronic (teeth grinding, attrition, abrasion, erosion) dental trauma caused by the current odontogenic pain, or painful sensation that is slowly evolving and becoming more pronounced. Many dental care procedures of cleaning cavities, restoring, through grinding teeth for prosthetic, to orthodontic movement of teeth can cause iatrogenic odontogenic pain. Additionally, dental materials applied on or near the pulp can cause painful stimuli.

Sometimes odontogenic pain can not find the real cause, we are talking about idiopathic odontogenic pain. However, you can find conditions and illnesses for which there’s reasonable suspicion that could manifest as an agonizing sensation in one’s teeth. In this respect, probably the most often mentioned aging, inner and exterior resorption of the teeth, hereditary hypophosphatemia, sickle cellular anemia, herpes zoster infections and Helps.

How to identify odontogenic pain?

Odontogena pain sometimes can be readily and easily determine, and sometimes the procedure was extremely hard and complex. Odontogena pain offers several of its characteristics which make it pretty much particular and recognizable. Nevertheless, the reliability of the features is normally low when seen separately. Reliability improves proportionally to the amount of analyzed features and their interrelationships are essential parts of a thorough scientific picture.

Attentive scientific study of the mouth majority will get the reason for dental discomfort such as dental care caries, dental stress, fractures of the crown or underlying, old and / or inadequate fillings, denuded dentin and others. For odontogenic pain characteristic that is often during the test can be deliberately provoke the painful stimulus, for example, by directing a plane of cold surroundings or water towards the suspected teeth. Given the actual fact that the reason for dental discomfort single teeth, the discomfort is certainly unilateral, or engages himself one part from the jaw and frequently you’ll be able to accurately localize though definitely not always. Suspicious teeth may be delicate to changes in temperature and pressure (bite or percussion). The tooth pain relief can be achieved by using a local anesthetic. Among the features of dental discomfort and its own limited length (times or several weeks). Sue Will the individual on chronic discomfort that endures for weeks and months, which is unchanged character, we must examine the possibility that the pain neodontogenog origin.

  How To Choose A Toothpaste?

In order to properly dentist diagnosed dental pain, must first take dental history which should include patient subjective description of the pain. The patient ought to be given information regarding the features of discomfort (dull, sharpened, drumming, capturing, stabbing, throbbing), its duration, regularity of occurrence, the technique of generation and so on. The data through the medical history ought to be complemented by a clinical examination of the oral cavity, inspection, palpation, percussion, heat test, test the vitality of dental pulp, and X-rays suspicious teeth or parts of teeth.

What can mimic odontogenic discomfort?

Although odontogenic discomfort has a few of his pretty much specific features, it isn’t always possible to state with certainty that the average person teeth distress in the face and lips cavity. Orofacial pain can have many of his nonodontogenic causes about which particular care should be taken when setting up a differential analysis. Neodontogena pain may have musculoskeletal, neuropathic, neurovascular, inflammatory, systemic and psychogenic background. Thus a wide range of possible causes of pain in the face and mouth the dentist can be a diagnostic challenge, but by taking a thorough dental care history, clinical exam and software of appropriate lab tests most factors behind dental pain could be properly discovered.

What’s dentin discomfort?

Based on Bender discomfort of odontogenic origins suggests dentin and pulp discomfort. Dentin and pulp discomfort occur due to arousal of two different neural fibres at different areas within the pulp (the gentle gum tissue encircled by dentin and put into the pulp chamber in the teeth). Terminations brzoprovodnih A-delta fibres are mostly on the border of the pulp and dentin, which means within the periphery of the pulp. These endings penetrate the dentinal tubules in depth from 150 to 200 microns. Nearly all of the A-delta materials are located in the crown area of the pulp, and are arranged densely in the area of the pulpal horns. On the other hand, sporoprovodna C-fibers are located in the deeper layers of pulp and permeate zone rich cells. Stimulus A-delta fibers causes a sharp, swift and stabbing pain (pain dentin), while C-fiber stimulation causes a dull, diffuse pain (pain pulp).

The cause of dental pain are changes in the dentin (the hard tooth tissue located under the enamel in the teeth crown or below the oral cement in the main canal). Perform hypersensitivity is because of exposure and starting the dentinal tubules (pipe), which conductor (conductor) discomfort, and become vunerable to external elements.

To Publicity from the dentine tubules exterior factors might occur due to put on of hard oral tissue, but additionally iatrogenic: unprofessional oral work, inadequate restorative preparation, unsuitable program materials for filling up teeth etc. Spending hard oral tissue (abrasion, attrition, erosion) regardless of the cause can lead to exposure of dentinal tubules external influences, resulting in hypersensitivity dentin and painful sensations which can sometimes be so severe that the patient requires that his tooth pulled out. As this is a healthy or too sensitive teeth, the patient then we should explain what it really is, solution it by tooth extraction and reduce his sensitivity to painful stimuli and thus save the tooth.

The pulp pain

Pulp pain or pulpalgija is usually pain that occurs stimulus tooth pulp. Each local inflammation within the pulp chamber causes discomfort which can express itself in various ways. Based on Melissa and affiliates features of pulp discomfort are:

  • pain can be oscillating personality as time improves or weakened
  • local provocation (high temperature, cold, pressure) raise the pain
  • medically and radiologically can be done to get the causes of discomfort (caries, fracture, etc.).
  • Endodontic treatment discomfort is taken out by
  • local anesthesia eliminates discomfort.

pulp discomfort can express as: come back (reversible) pulpitis, irreversible (irreversible) pulpitis, severe apical periodontitis and severe apical abscess.

  Baby Bottle Tooth Decay

Return (reversible) pulpitis is usually defined as inflammation of the pulp of lower intensity. Mild and short-irritating stimuli such as initial caries lesions, cervical erosion, occlusal attrition, enamel fractures and numerous dental procedures (eg, curettage periodontal) lead to exposure of dentinal tubules, which can cause reversible pulpitis. Reversible pulpitis usually asymptomatic. But if there are symptoms, then have a specific form of appearance. Stimuli such as hot or chilly liquid or air flow cause a sharp but transient pain. By detatching these stimuli, which usually do not cause unpleasant sensations, pain immediately disappears. Warmth and cold cause different pain responses in healthy pulp. When the warmth source is placed on the tooth, there is a delayed initial response, and the intensity of the pain increases proportionately to the increase of temp.

On the other hand, the pain caused by chilly stimulation occurs at this point, except that it’s decreased concerning whether the frosty stimulus savings. Predicated on these observations it could be figured the response as well as the healthy as well as the unwell pulp depends upon adjustments in intrapulpnom pressure.

I irreversible (irreversible) pulpitis is normally asymptomatic or an individual appear only gentle symptoms. Alternatively, some sufferers irreversible pulpitis could be associated with temporary or permanent episodes of spontaneous pain (not caused by external stimuli). The pain of irreversible pulpitis can vary from razor-sharp to dull, may be localized or diffuse and this can take a number of minutes or several hours. Localization pulp discomfort is much more challenging than determining the area of discomfort periradicular origin and everything it tough to localize as intense. The use of external stimuli such as for example heat or frosty can cause extented pain. In the current presence of severe discomfort, the pulp response differs based on whether it’s healthy or swollen. Eg., Through the use of heat towards the teeth with irreversible pulpitis results in instantaneous unpleasant stimulus, as the software of chilly can cause prolonged pain. Sometimes, the application of chilly in patients with painful irreversible pulpitis causes vasoconstriction and decrease the pulp pressure, which reduces pain. In odontogenic shown pain, discomfort that originates from teeth could be shown on the various other orofacial buildings and conceal the true cause of discomfort. It isn’t often the fact that pain due to pathological changes in the pulp of one side of the jaw techniques to the opposite page faces. Odontogena reflected the pain often associated with irreversible pulpitis. The most frequently manifests itself in the back parts of the top or lower jaw.

Acute apical periodontitis producing growth of pulp swelling in periradicular area. Irritating elements are mediators of irritation from irreversibly swollen pulp, bacterial harmful toxins from necrotic pulp, chemical substances (washing alternative and disinfecting main canal), excessive fill up, excessive instrumentation and overcharging underlying canal. Symptoms of acute apical periodontitis vary from medium to express spontaneous pain, to pain when chewing and occlusal contacts. If acute apical periodontitis result of inflammation from the pulp, feasible sensitivity to incredibly hot and frosty and level of sensitivity to electric stimuli. Alternatively, if the severe apical periodontitis consequence of necrosis from the pulp, the teeth will not display indications of vitality. Pressing tooth and percussion could cause discomfort. Radiographic could be observed thickening of the periodontal ligament, but he can often stay and a full-size and fully intact. Histologically, in the apex of the tooth see localized accumulation of polymorphonuclear leukocytes and macrophages. Sometimes it is possible to spot and less area liquefaction necrosis (abscess). Although bone resorption and roots can be histological, radiological usually not visible. Treatment consists of removing irritating factors that led to the starting point of severe apical periodontitis.

Sometimes (asymptomatic) apical periodontitis happens when oral pulp starts to gradually perish out without leading to symptoms and gradually release dangerous inflammatory real estate agents low pathogenicity or low concentrations. Sometimes (asymptomatic) apical periodontitis is quite often the consequence of a failed endodontic treatment that continues to be hidden until symptoms show up. Any chronic back again easily surpass the severe stage when disease occurs with existing new, when reduced immunity, or when to increase the virulence of microorganisms. This type of apical periodontitis is associated with resorption radiological periradicular alveolar bone. Patients usually do not complain of painful stimuli, and to test the vitality react badly because they do not cause painful sensations. Eventually, if there is a perforation of the alveolar bone, palpation of the perforation can cause discomfort and bad pain.

  Understanding the Materials Used in Dentistry

Acute (symptomatic) apical abscess may be localized or diffuse liquefaction lesion that destroys periradicular tissue and can be a strong inflammatory response to microbial or nemikrobne irritants arising from necrotic pulp. Depending on the severity of the reaction, patients with acute apical abscess usually feel moderate to serious pain and also have inflammation. Sometimes it could display and systemic manifestations of infectious procedures such as for example fever, weak point or leukocytosis. How exactly to severe apical abscess comes only when the necrotic pulp, teeth shows no influence on the heat and electric stimuli. But these the teeth are often delicate to percussion and palpation. With regards to the degree of devastation of periradicular cells, radiographic findings vary from growth of periodontal crack (hardly ever) to the clearly indicated resorptive lesions (often).

What is the treatment odontogenic pain?

The treatment methods of dental care pain depends on its cause. If the cause of dental care caries, the procedure is restorative, which include cleaning of teeth caries, teeth pulp security and recovery. In teeth injury as the reason behind teeth pain, removed traumatic teeth, but with regards to the injury can range between putting bandages dentin and pulp safety to endodontic process and immobilization of tooth. Dentin hypersensitivity tooth pain and heal the closure of dentinal tubules, avoiding transmission of external stimuli to the pulp. More recent attempts to reduce dentine hypersensitivity are going in direction of remineralization and occluding the open up dentinal tubules. For this function apply to arrangements predicated on calcium-sodium fosfosilikata who’ve the capability to quick launch of calcium mineral, phosphate, sodium and silicate and development of a fresh layer on the top of dentin, which closes open up dentinal tubules. Pulp discomfort, with regards to the condition of pulp, may necessitate just pulp capping (directly or indirectly) the appropriate preparations, but also completely endodontic dental treatment, including treatment, disinfection and root canal filling. Sometimes endodontic treatment must be combined with endodontic-surgical procedures.

Depending on the cause of dental pain and medical condition of the patient, the dentist may recommend taking analgesics, antipyretics and antibiotics.

How to prevent dental pain?

Avoiding the causes of oral pain may be the best approach of avoiding her. This mainly refers to oral caries as the utmost common reason behind the looks of dental discomfort. With regular and appropriate oral treatment and teeth, sufficient nourishment and control appointments to the dental professional can significantly decrease the occurrence of oral caries, and thus the need for endodontic treatment. By avoiding the consumption of drinks that have erosive effects (carbonated and / or highly acidic drinks) reduces the risk of dental erosion, which is one of the most common causes of dentin hypersensitivity. The application sports mouthguard, teeth are protected from trauma and injury, thus preventing and dentin and pulp discomfort.


Odontogenic discomfort is among the most common varieties of pain within the orofacial region, and its most typical cause of oral caries. Odontogena discomfort can often be named neodontogena discomfort and vice versa. Preventive dental oral hygiene measures are usually preventable causes of dental pain.
