4 Unexpected Causes of Tooth Pain

Tooth pain can be aggravating and debilitating, especially when it affects your quality of life. Normally tooth pain is easily diagnosed and stems from a cavity, periodontitis, trauma, or other common dental problems.

Sometimes, however, no immediate explanation is apparent, but the pain is real. Here are four unexpected reasons your teeth might cause you pain.

1. Neurovascular Headaches

Migraine and cluster headaches are called neurovascular headaches because they are caused by changes in blood vessels of the neck and head. Pain you experience during a migraine headache can be transmitted along nerves to other parts of your body. This phenomenon is called referred pain.

Your teeth can experience referred pain during a headache. Referred pain can cause inflammation to spread to blood vessels near your teeth. Most often, your upper and lower premolars and upper canine teeth throb and pulsate during a headache, sometimes even after you no longer have a headache.

2. Excessive Exercise

Rigorous exercise evokes images of teeth-jarring activity or injuries that cause tooth trauma. Often athletes believe their tooth pain starts because of cavities brought on from drinking sugary sports drinks. However, one or more teeth might start to hurt because you exercise rigorously, but for an entirely unexpected reason.

One study found a link between athletes that work out heavily and high levels of tooth decay. The surprising culprit was saliva. As you exercise your mouth produces less saliva, which makes your mouth drier. Drinking water or other fluid does not actually replace the unique properties that saliva has. Less saliva means less protection for your teeth from tooth decay.

Additionally, the study showed that alkalinity of saliva increases as you exercise. Saliva is less able to protect your teeth when pH levels are off. In fact, very alkaline saliva weakens teeth and puts them at risk for plaque.

3. High Stress Levels

Stress makes you worry at night, brings on headaches and stomach aches, and even leaves you feeling depressed. But when you have a toothache that won't go away, stress is probably the last thing you think is the cause of your pain.

Another symptom of stress is bruxism, or teeth grinding. Stress can make you clench your jaw during the day and grind your teeth at night while you sleep. Long-termed bruxism inflames the muscles in your jaw, which radiates to your teeth. Over time, bruxism causes more damage than just sore muscles. Uncontrolled grinding wears away crowns, fillings, and eventually tooth enamel, putting your mouth at risk for infection.

4. Sinus Infections

A simple cold or flu can send bacteria into your sinus cavities where long-term infection eventually inflames your sinus region and places pressure on other regions of your face or head. Chronic inflamed sinus regions are referred to as a sinus infection or sinusitis. In addition to a fever, cough, headache, and runny nose, you might develop pain in your teeth.

The inflamed sinus region behind your cheekbones and on both sides of your nose is responsible for pain that radiates to your upper jaw and the sensitive roots of your upper teeth. Pain increases when you walk, bend over, or tilt your head in any direction. You may feel a continuous dull ache in several teeth rather than a sharp pain specific to one tooth.

When you experience any kind of toothache, visit your dentist first. He or she will examine your teeth to check for tooth decay, cavities, gingivitis, infection, or other common dental problems that cause tooth pain. Don't put off a dental visit for tooth pain that diminishes your quality of life. Call Gregory S. Rutherford, DDS, PA , to make an appointment with a caring professional for your next exam.

If your dentures aren't fitting like they used to, it may be time to consider denture relining. Denture relining is a process that your dentist can use to provide a new, more comfortable fit for your existing dentures without replacing them. Here is an overview of denture relining so that you know what to expect from the procedure and can have an informed conversation with your dentist. Relining Procedure Denture relining is usually a simple procedure that can be completed in less than an hour. When you visit your dentist, he or she will first examine your mouth to assess the level of irritation that is present. If significant sores or swelling is present from the poorly fitting dentures, the dentist may recommend a temporary reline while your mouth heals and allow you to return later for the permanent reline. To perform a permanent reline, your dentist will first clean your dentures and sand away a small amount of material on the denture plate. After removing material in areas that are causing uncomfortable contact with your mouth, the dentist will then apply the soft or hard relining resin to the dentures. You will place the dentures back in your mouth and bite down gently to make an impression in the resin. Once the resin hardens, the reline is complete. Soft Relining Soft relining resin is one of two optional materials for use in denture relining. This resin is made of silicone and creates a softer, more comfortable base for the denture. Soft relining is the best choice for people with thin or especially sensitive gums, as there is less chance that irritation will develop in the future. The downside of soft relining is that because the material is softer, it is also less durable than the original denture or hard relining resin. This means that you will require more frequent visits for relining than if you choose to use hard resin. Soft relines are a better choice for older patients who usually have thinner gums and more advanced recession of the gums and other tissues in the mouth. Hard Relining Hard relining is the standard for denture relining, as it is both long-lasting and comfortable for all but the most sensitive gums. Hard relining resin is made from acrylic that is similar in composition to the original acrylic of your dentures. With hard denture relines, you shouldn't expect to need your dentures relined more often than every one to two years. The only potential drawback of hard denture relines is that they cannot always be completed on the day of your visit. While your dentist may be able to apply the reline, take an impression of your mouth, and harden the relining putty in one sitting, he or she may choose to send the impression to a dental laboratory for development. This will leave you without your dentures for a few days but is sometimes necessary to ensure the hard resin fits perfectly. Relining Benefits Denture relining resolves a number of issues that you may think would require replacement of your dentures. Sores, irritation, and general discomfort are the primary reasons that many patients consider relining. You may find that it is easier to chew with your relined dentures, and relining can also resolve slurs, lisps, and other speech difficulties caused by improper denture fit. Relining is also less expensive than an entirely new set of dentures. Even if you maintain a perfect oral health routine, the shape of your mouth will change over time. Denture relining is the best way to update an old set of dentures so that they fit comfortably throughout your life. If your dentures don't fit like they used to, Gregory S. Rutherford, DDS, PA can provide denture relining that will make them fit like new again!
