Dental Related Allergies

Table of Material

Allergy ( Greek : allos – additional, ergein – work) shows a hypersensitivity reaction of the organism to non-infectious, for health otherwise harmless substances (antigens, allergens). Many of these substances come from the environment. An allergic reaction could cause local or general (systemic) symptoms. Local symptoms are limited by the organ or organ program by which the allergen inserted the body, as the general symptoms express themselves at the amount of the complete organism. Outward indications of gentle reactions could be rhinitis, conjunctivitis, urticaria and so on. Severe reactions such as for example anaphylaxis and angioneurotic edema may business lead the body right into a condition of surprise, and in the lack of untimely and insufficient treatment can result in death.

Allergies have become common reactions from the organism and nearly every person throughout existence has experienced an allergic reaction. Allergies are more common in more youthful people, especially in developed countries among the city population. It is believed that allergic diseases happen in 5 to 10% of the population. Research has shown that actually 15 to 25% of People in america are sensitive to particular substances (for example the rate of recurrence of allergic rhinitis is definitely estimated at 7-10% of the total USA human population).

There is no unambiguous and full answer to what can cause increase in the number of allergic individuals. According to interpretations of some specialists find at fault are available in the food, specifically in several additives which are put into foods and in genetically customized food. However, the reason is probable much wider and more technical.

Perhaps one of the most common crisis situations that could take place in the dentist office is an severe allergic reaction. For that reason, to be able to prevent undesired and occasionally life-threatening situations that may result from this condition, the dentist should know and be able to:

  • identify the patient who has a tendency to have this condition,
  • recognize changes in the soft oral tissues resulting from reactions,
  • modify the plan of dental treatment in immunocompromised and sensitive patients,
  • recognize the signs and symptoms of acute reactions, and take appropriate therapeutic measures.

Allergic reactions that may occur in the dental office are usually associated with local anesthetics , antibiotics , a nalgesics and the ingredients of dental materials . If the patient has before undergone some form of response, he must completely inform the dental professional about it. Based on these info, the dental professional should conclude if this is actually the true response or a number of the circumstances that are much like allergies.

The outward symptoms that often accompany this problem, and may happen only or in mixture are:

  • urticaria (a allergy of round, reddish colored welts on your skin that itch intensely) ,
  • swelling,
  • skin rash,
  • chest tightness,
  • dyspnea (difficult or labored breathing) ,
  • rhinorrhea ( a condition where the nasal cavity is filled with a significant amount of mucus fluid ) ,
  • conjunctivitis (inflammation of the conjunctiva of the eye).

related Local anesthetics

While many patients worriedly inform their dentists that they may be sensitive to local anesthetics, true allergies to local anesthetics which are now popular in dentistry (local anesthetics from the amide organizations) are fairly uncommon. The reactions induced by intravenous shot of an area anesthetic or a reaction to the vasoconstrictor in the neighborhood anesthetic could cause symptoms which are frequently replaced with allergies. Besides, patient who’s afraid of teeth method or needle when applying local anesthetic, due to his fear frequently begins to perspire, become pale and his cardiovascular begins to pound, which may be misinterpreted as allergic reaction to local anesthetics. If the aforementioned causes are excluded, and prior health background is caution of the true allergy to local anesthetics or their substances, the dentist must know what sort of anesthetic an individual is delicate to and discover a suitable substitute. If it’s determined that the individual is hypersensitive to local anesthetics from the ester group (electronic.g. tetracaine or procaine ), then your anesthetic out of this group must be changed with one of the anesthetic from your amide group.

Namely, if the patient is sensitive to one of the ester anesthetics, then he is allergic to all anesthetics from your ester group. On the other hand, if there is an allergy to one of the anesthetic of the amide group (e.g. lidocaine , mepivacaine or prilocaine ), there is only an allergy to a specific anesthetic, and not the whole group. So, it is possible that contraindicated amide anesthetic to be replaced by another amide anesthetic. When applying articaine the dentist should be especially careful because it is the amide anesthetic with an ester group which can easily cause allergic reaction.

The patients may also be allergic towards the substances which are put into local anesthetic to boost their properties, such as for example methylparaben , bisulfite and so on. In cases like this just anesthetics that usually do not contain these potential things that trigger allergies should be used .

In circumstances where it isn’t possible to find out which anesthetic or its component the patient is certainly allergic to (which caused an the problem during past dental care), one alternative would be to refer the individual to the allergic reaction testing. The individual should be described which the testing is essential because repeated severe allergic reaction could be fatal.

Penicillin, among the best known & most trusted antibiotics, frequently causes the problem. It’s estimated that penicillin and its own derivatives cause allergies in 5 to 10% of individuals, of which 0.04 to 0.2% of the instances are in form of anaphylactic reactions .

Probability that it will go to sensitizing of the organism to penicillin depends on the route of administration. Dental application results in sensitization in about 0.1% of the individuals, while the surface application of penicillin (e.g. ointment placed on the skin) causes sensitization in 5 to 12% of individuals. Therefore, it is always recommended oral software, followed by intramuscular injection.

If a patient knows that he is sensitive to penicillin, then he must inform the dental professional, who will, if necessary, instead of penicillin preparations rewrite erythromycin or clindamycin. Antibiotics that can show cross-reaction, such as for example ampicillin , carbenicillin and methicillin also needs to be prevented. In circumstances when penicillin may be the first selection of treatment, and there’s a suspected allergic reaction to penicillin, allergic reaction testing is preferred.

In sufferers with no health background of allergic reaction to penicillin, it could be administered orally. Following the initial dose, the individual should be supervised for 30 mins to be able to note with time and look after possible allergic attack.

Acetylsalicylic ac > temporary narrowing of the bronchi – airways into the lungs caused by contraction of the muscle tissue ). Due to a severe condition characterized by acute bronchospasm , rhinorrhea and urticaria , it is not recommended to use these analgesics in people who suffer from asthma. Moreover, these patients should avoid taking any analgesic which contains acetylsalicylic acid or some other salicylate. Paracetamol based analgesics are considered to be analgesic of choice in danger of allergic reactions to aspirin and/or NSAIDs.

Other dental materials which can cause an allergic reaction

dental In both the members of the dental team and patients there were many cases of allergy symptoms related to connection with products containing rubberized or latex , such as for example protective rubberized dum found in endodontics (underlying canal treatment) and latex gloves. In this sort of hypersensitivity, in case there is doubt all components and the gear containing rubberized or latex ought to be avoided.

The solutions for mouthwash and toothpastes that have phenol, antiseptics or flavoring elements , may also result in a hypersensitivity response, which is ideally manifested for the dental mucosa or for the lips.

Dental components and their parts, such as dental amalgam, acrylic, composite, nickel, eugenol and talc are also known as potential allergens.

Oral manifestations of allergic reactions

In so called type I hypersensitivity reactions (immediate hypersensitivity reaction) in the oral cavity oral lesions , hives , swelling or angioneurotic edema may occur. After contact with an allergen, hypersensitivity reaction develops rapidly. Painless swelling of the soft tissues in the oral cavity may be accompanied by unpleasant burning sensations. Oral lesions usually last 1-3 days, after which spontaneously heal. In the procedure dental antihistamines are used, and re-contact using the allergen ought to be avoided.

allergies Within the hypersensitivity response type III (defense antigen-antibody complexes are shaped) within the mouth white-colored , erythematous (reddish colored) or ulcerative lesions can happen. These lesions happen within a day after connection with an allergen. There were many cases of the kind of hypersensitivity in individuals with orthodontic home appliances that were delicate to nickel in orthodontic cables.

Contact stomatitis is delayed allergic reaction (hypersensitivity response type IV) caused by activation from the cellular disease fighting capability. It really is manifested by the looks of inflammatory lesions in the mouth mucosa after connection with an allergen. Things that trigger allergies can be oral materials (such as for example amalgam, composites, adhesives, acrylates, nickel, precious metal, mercury, palladium, etc.), components when planning on taking impressions, whitening gels, toothpastes and mouthwash solutions. After finding the reason for hypersensitivity response, the dental practitioner should stay away from material that triggered the issue.


Allergic reactions are relatively common complications that can occur during dental treatment and after dental care. The reaction of the organism to an allergen can be mild, but also very strong and even life-threatening. The dentist should always be alert to the previous conditions to avoid unwanted situations and prevent unpleasant effects. When necessary, the dentist can modify planned dental treatment in order to minimize the risk of future conditions.
