Links between allergies and dental problems

September 29, 2020

Studies have viewed that allergic reactions to medicament and food items are gum problems, pharyngitis, decay, dry mouth, mouth sores, pain in teeth, bad breath, and sensitivity. The majority of the reported dental problems are pharyngitis, decay, dry mouth, mouth sores, pain in teeth, and sensitivity.

There is little cognizance of how toothache, sore throat, and tooth decay can result from allergies. But people know more about the reactions from allergic, such as sneezing, itchy nose, watery eyes, and others. Experience dentists can easily detect dental problems if the dental issue is caused by allergy from food items, medicament, or other possible determinants.

Can sinus pressure cause teeth hurt?

A bacterium that is linked to cold and flu can cause a sinus infection, and the cheekbone’s sinuses are affected by sinus infection leading to pressure and toothache. It is general knowledge that the fundamental reasons behind a toothache are gum disease and decay. But there are other determinants with lesser recognition, such as sinusitis that leads to pain.

How to know the difference?

Distinguishing between dental pain and sinus pain is realizable. Notwithstanding, early and well-timed visit to a dentist is crucial.

Spring allergies trigger sinus pain, and slight pain across the nasal passages and forehead region comes with a toothache. Toothache similar to experiencing close to upper jawbone sinuses to the upper grinder (molars) results from sinus pain.

To know if the tooth pain is due to sinus infection, the patient has to ascertain if the toothache will aggravate by doing some head movements (by shaking the head). If the tooth pain increases, the patient can conclude that the discomfort is a sinus infection.

Upon confirmation, the next thing is appropriate medicament.

Tooth pain and tooth decay can be caused by dry mouth.

Neither root canal routine nor filling is the best option that dentists use for patients with tooth decay. Patients with dry mouth are advised to change their drinking habits and medicament. A patient who undergoes toothache and damaged teeth is a result of dry mouth related to allergy.


During the spring, patients with dry mouth also suffer from hay fever and pollen allergy. Tooth decay and tooth pain are caused by bacteria, resulting from a low saliva level in the mouth. This is known as dry mouth.

A sore throat caused by allergy

As a result of swollen lymph nodes, sore throat can also lead to tooth pain. As an allergic reaction to most patients (with dental issues), too much mucus production is due to unconsciously taking in pollen or dust; when they pass through the throat, it leads to coughing, sore throat, and tickling.

Chronic allergies that result in cavities in children

Symptoms that adults with allergies suffer from, children suffering from such allergies also show the same signs.

Some of those symptoms are headache, snoring, running nose, coughing, and mouth breathing, among others. If those symptoms are ignored, it can result in cavities (caused by a low level of saliva in the mouth). Regrettably, some medicament, such as inhalers, can also cause tooth decay for children.

Things that could induce allergies are dust mites, trees pollen, weeds, animal dander, flower pollen, insect stings, and grass.

Food sensitivities and seasonal allergies

Seasonal allergies, such as nose inflammation, can come from exposure to substances like mold, pollen, pet hair, dust mites, fur feathers, and several other airborne substances, given that these substances mostly appear during specific seasons. These allergic reactions are known as seasonal allergies. Patients suffering from such allergies show symptoms such as sinuses linked headache, running nose, coughing, blocked sinuses, mouth breathing, and snoring. Most patients complain of discomfort in their teeth after eating or drinking some specific foods. That is, some food items can also cause dental issues.


Dealing with food sensitivities

After taking the orange juice, sports drinks, yogurt, and tomato soup, most people complain of discomfort in their teeth because their teeth are sensitive to highly acidic food items. There must be a balance between food items with alkaline and acidic food items to sustain oral health. The most preferred way of dealing or reducing the acidity in some of our food items is to get more of alkaline food items.

People with sensitive teeth should try and prevent foods that are extreme (that is too cold or hot). Tooth pain experienced from taking ice-cream, fruit juices that are sugary and alcoholic beverages shows tooth enamel damage and tooth sensitivity. Patients with such needs to see a dentist for a regular dental check-up and treatment at the early stage to prevent extra damage.

Oral allergy syndrome

Some vegetables and fruits have a similar structure to pollen. Most people are suffering from allergies caused by an allergic reaction as a result of cross-reactivity because individuals take-in some kinds of foods. Stuff like peaches, apples, fresh herbs, tomatoes, cucumbers, bananas, and oranges can cause allergic reactions such as the tongue’s tickling feeling, constant sneezing, scratchy throat, swelling lips, and nasal congestion. The most effective way to control Oral Allergy Syndrome (OAS) is by preferring canned vegetables and fruits, heating, or cooking vegetables before consumption. Patients should also ensure that they peel off the skin of fruits as well as vegetables before eating. Another form of allergy associated with pollen is Oral Allergy Syndrome (OAS).

Allergic reactions caused by toothpaste and other dental care products

Like allergies to dental filling materials and metals, a few patients also complain of an allergic reaction to toothpaste.

The symptoms comprise itching and peeling of lips, swollen gums, irritated tongue, and sore mouth—ingredients used in making toothpaste such as flavorings can cause these reactions. Therefore, avoiding dental care products containing them is the best option.

However, dentists may suggest low-potency steroids, and some other medications handle the allergic reaction.
