Why Do You Have A Toothache? 3 Surprising Toothache Causes

When you are going about your daily life and suddenly experience a nagging, distracting pain in your teeth, you may not know what to do. After all, you have done nothing out of the ordinary that would cause your teeth to hurt. However, there are many potential causes for your sudden toothache. So, before you panic and head straight for the nearest emergency room, learn about the possible reasons for your toothache and the solutions you can try. If none of these seem to fit the bill, then your dentist and/or the emergency room await your visit. 

Seasonal Allergies

If you suffer from seasonal allergies, you know that they can cause your entire body to just feel off-kilter. These problems occur primarily in the facial and cranial region of your body. You suffer from a runny, stuffy knows, you feel pressure in and around your eyes and sinuses, and you just feel miserable. 

However, what you may not know is that your seasonal allergies can also manifest themselves in the form of a nagging toothache. This pain usually occurs in your upper teeth, particularly your molars or the teeth immediately adjacent to your molars (known to dentists as premolars).

So, before you rush off for emergency dental care, try taking an antihistamine and/or a decongestant, and rest for an hour or two. If the pain lessens or disappears from standard allergy treatments, this is likely the root cause for your pain. 

Sinus Infection

By the same token, toothaches can be an unpleasant side effect of a sinus infection. The pressure that builds up in your sinuses that causes you face to ache and feel like it is going to explode, can resonate in your teeth as well. 

This pressure and swelling in your sinuses can actually affect the nerves in your face that lead to your teeth. This causes pain in your tooth even though there is not a dental reasons for the pain. 


Shingles is a viral infection that is caused by the same virus as chickenpox. It is generally characterized by a painful blistering rash on your torso, but can also extend to the face and extremities. 

However, shingles can have other effects upon the body as well because it is technically an infection of the nerve cells in your body. This can result in mouth pain in two ways. You may develop skin lesions on or in your mouth that resemble canker sores, or the nerves leading to your teeth can become irritated causing tooth pain. 

As you can see, toothaches do not always have a straightforward or obvious cause. If, however, you assess all these possibilities and still have pain, seek help from a dentist like Joseph Craig. A dental professional can be sure to remedy dental pain quickly and efficiently.
