Tooth pain is an unwelcome surprise after gulping down a nice cold drink or chomping on some corn on the cob. Whether it's a nagging, dull ache or a sharp jolt that makes you jump, tooth pain can be cause for concern [1,2].
Good dental hygiene (yes, including, flossing) and regular visits to the dentist go a long way in preventing tooth pain, but even the pearliest whites aren't immune . Dental problems grow more common with age yet can begin in childhood, long before adult teeth come in.
Tooth pain may seem unimportant, but it can be a warning sign of worse things to come. Teeth and gums help shield the body from infection, and when they break down, the body loses this natural defense.
Common symptoms are:
That irritating toothache is often a sign of decay caused by a buildup of bacteria in the mouth. What starts as a colorless, sticky film, called plaque, can quickly progress to hardened, yellow or brown deposits called tartar . Without proper dental hygiene, the bacteria can cause erosions in teeth and infections in the surrounding area.
- Tooth decay: Acid produced by bacteria in the mouth can break down the hard tissues of the teeth.
- Inflammation of the gums: Swollen gums can be quite uncomfortable and are a sign of bacteria buildup in the mouth.
- Abscess: An infection that has been brewing for some time can produce a pocket of pus in teeth or surrounding tissues .
- Third molars: While some people are able to keep these "wisdom teeth," there's often not enough room in the mouth and overcrowding can cause pain.
- Teeth grinding: This can occur during the day or at night while sleeping and can irritate the nerves in the teeth and other areas.
- Dental work: Teeth can be especially sensitive after a visit to the dentist for a filling or crown.
- Jaw joint inflammation: Problems with the jaw joint and muscles may cause pain that feels like it is coming from your teeth .
- Trauma: A cracked tooth is not only painful and unsightly but can also increase the chance of infection.
- Teething: In children, the eruption of baby teeth and later adult teeth commonly cause discomfort.
- Poor diet: Eating lots of sugary snacks and drinks feeds bacteria in the mouth and can lead to painful infections and other problems.
- Poor dental hygiene: Regular brushing and flossing helps keep dental problems at bay and can prevent toothaches.
8 Possible Toothache Conditions
The list below shows results from the use of our quiz by Buoy users who experienced toothache. This list does not constitute medical advice and may not accurately represent what you have.
Tooth abscess (infection)
A tooth abscess is a collection of infected material (pus) in the center of a tooth. It is due to bacterial infection.
Top Symptoms: severe jaw or tooth pain, swollen jaw, jaw stiffness, tooth pain that gets worse with hot, cold, or sweet beverages, warm and red jaw swelling
Symptoms that always occur with tooth abscess (infection): severe jaw or tooth pain
Urgency: Primary care doctor
A dental cavity (caries) is an infection of the tooth, which is the result of long-term acid production by bacteria that sit on your teeth. This can result in pain and the spread of infection into the tooth pulp, and, if untreated, into your jaw bone or bloodstream. The development of a cavity is highly dependent on your lifestyle and is largely a preventable disease. Poor dental hygiene, a diet high in sugar, and the presence of aggressive bacteria in your mouth increase the risk of development of cavities. Once you have a cavity, it is important to see a dentist and have the cavity filled and improve oral hygiene at the recommendation of a dentist. Filing a cavity can protect against the spread of infection and improve your symptoms. Failure to fill a cavity may result in removal of the tooth (extraction) or cleaning/drilling into your jaw (root canal).
Top Symptoms: dry mouth, toothache, tooth pain that makes chewing difficult, pain in the top row of teeth, tooth pain that gets worse with hot, cold, or sweet beverages
Symptoms that never occur with dental cavity: spontanenous tooth pain
Urgency: Primary care doctor
Dental cavity requiring a root canal or tooth extraction.
Top Symptoms: dry mouth, toothache, spontanenous tooth pain, tooth pain that makes chewing difficult
Symptoms that always occur with severe cavity: spontanenous tooth pain
Urgency: Primary care doctor
Temporomandibular joint (tmj) dysfunction disorder
Temporomandibular Joint Dysfunction is often caused by a variety of factors, including daily habits, your teeth alignment, and even stress. It usually affects one side of the jaw, but in some people it can affect both sides. People with TMJ dysfunction will typically experience pain on one side of the face that is worse with chewing, yawning, or other movements of the jaw. With some simple changes in your daily habits and other at-home treatments, most people with TMJ dysfunction will experience relief of their symptoms within weeks.
Treatment for temporomandibular joint dysfunction usually includes avoiding eating hard foods or foods that require a lot of chewing. Good posture and relaxation techniques may help relieve tension in the muscles that connect to your temporomandibular joint. In people who clench or grind their teeth, a mouth guard worn at night (and fitted by your dentist) may also help relieve your symptoms. Pain relievers, like ibuprofen (Advil, Motrin), can also help.
Top Symptoms: dizziness, pain, restricted movement, and clicking sounds from jaw, history of headaches, jaw pain, pain in the back of the neck
Symptoms that always occur with temporomandibular joint (tmj) dysfunction disorder: pain, restricted movement, and clicking sounds from jaw
Urgency: Primary care doctor
Infected wisdom tooth (pericoronitis)
Pericoronitis of the 3rd molar is an infection of the gums surrounding the 3rd molar (wisdom tooth). It almost never happens to normal teeth because wisdom teeth take a long time to break the gums (erupt). It's believed that once the wisdom tooth breaks the surface of the gums, the bacteria in the mouth get into the gums at that spot and cause an infection. This is also worsened by food particles that build up in the area.
Top Symptoms: possible wisdom tooth pain, moderate tooth pain, tooth pain that makes chewing difficult, severe tooth pain, mild tooth pain
Symptoms that always occur with infected wisdom tooth (pericoronitis): possible wisdom tooth pain
Urgency: In-person visit
Acute viral sinusitis
Acute viral sinusitis, also called viral rhinosinusitis or "sinus infection," occurs when viruses take hold and multiply in the sinus cavities of the face.
It is most often caused by the same viruses that cause the common cold and spreads the same way, through an infected person's coughing or sneezing.
Because children have small, underdeveloped sinuses, this illness is far more common in adults.
Symptoms include clear nasal discharge (not greenish or yellowish,) fever, and pain if facial sinuses are pressed.
If there is rash, severe fatigue, or neurologic symptoms (seizures, loss of sensation, weakness, or partial paralysis,) see a medical provider to rule out more serious conditions.
Diagnosis can usually be made through history and examination alone.
Antibiotics only work against bacteria and cannot help against a viral illness. Therefore, treatment consists of rest, fluids, and fever/pain reducers such as ibuprofen. (Do not give aspirin to children.) Symptoms of viral sinusitis last for about seven to ten days. As with the common cold, the best prevention is frequent and thorough handwashing.
Top Symptoms: headache, cough, sinusitis symptoms, sore throat, congestion
Symptoms that always occur with acute viral sinusitis: sinusitis symptoms
Symptoms that never occur with acute viral sinusitis: being severely ill
Acute bacterial sinusitis
Acute bacterial sinusitis, also called bacterial rhinosinusitis or "sinus infection," has symptoms much like viral rhinosinusitis but a different treatment.
Any sinusitis usually begins with common cold viruses. Sometimes a secondary bacterial infection takes hold. Like cold viruses, these bacteria can be inhaled after an infected person coughs or sneezes.
Anyone with viral sinusitis, upper-respiratory allergy, nasal passage abnormality, lung illness, or a weakened immune system is more prone to bacterial sinusitis.
Symptoms include thick yellowish or greenish nasal discharge; one-sided pain in the upper jaw or teeth; one-sided sinus pain and pressure; fatigue; fever; and symptoms that get worse after first improving.
See a doctor right away for severe headache, high fever, stiff neck, or vision changes. These can indicate a medical emergency.
Diagnosis is made with a simple examination in the doctor's office.
Bacterial sinusitis can be treated with antibiotics, but this is not always necessary. Often rest, fluids, and over-the-counter pain relievers and decongestants are enough.
Prevention is done through good lifestyle and hygiene to keep the immune system strong.
Top Symptoms: fatigue, headache, cough, sinusitis symptoms, muscle aches
Symptoms that always occur with acute bacterial sinusitis: sinusitis symptoms
Symptoms that never occur with acute bacterial sinusitis: clear runny nose, being severely ill
Urgency: Primary care doctor
Osteonecrosis of the jaw
Osteonecrosis is a process in which bone cells deteriorate and die. Osteonecrosis of the jaw (ONJ) occurs specifically in the cells of the maxilla and mandible jaw bones. This is a rare condition associated with dental extractions and bone therapies often used in cancer treatments, and occurs when jaw bones become uncovered by the gums and lose adequate blood flow.
Symptoms that may indicate a developing case of ONJ include pain, redness and tenderness of the jaw, jaw numbness,(https://www.buoyhealth.com/symptoms-a-z/trouble-swallowing/). Once ONJ has developed, usually over eight weeks, the primary symptom is lesions that expose bone.
Surgery or surgeries to remove the affected bone is often necessary with ONJ. Other less invasive treatments may include antibiotics and over-the-counter pain medication.
Rarity: Ultra rare
Top Symptoms: jaw pain, jaw lump, toothache, swollen jaw, heavy jaw
Symptoms that always occur with osteonecrosis of the jaw: jaw pain
Urgency: Primary care doctor
Toothache Treatments and Relief
By the time tooth pain hits, there's usually an underlying problem that requires a thorough examination by a dentist. So, it's best to address the problem before it happens in the first place.
- Brushing: Most people rush this basic part of dental hygiene. Be sure to clean all surfaces of your teeth with fluoride toothpaste and gentle back and forth motions for at least two minutes. Change your toothbrush at least every three months.
- Flossing: There's a reason the dentist always asks about this important step. Cleaning the space between teeth and gums once a day removes bacteria and prevents infection and inflammation.
- Fluoride rinse: These over-the-counter solutions are a popular supplement to the fluoride already found in toothpaste.
- Antibacterial mouthwash: These rinses, which typically contain alcohol or chlorhexidine, reduce the amount of bacteria in the mouth.
After a toothache develops and before you make it to the dentist, there are a few remedies that can help relieve the pain.
- Numbing gels: Products containing benzocaine, such as Orajel, are applied directly to an area of discomfort and can make it easier to eat or drink with a toothache.
- Painkillers: Advil, Motrin or other products with ibuprofen are effective for treatment of dental pain. Tylenol is a good alternative and can be alternated with ibuprofen for even stronger pain relief.
- Clove oil: A few drops of this natural remedy can be applied directly to the painful area in the mouth.
- Salt rinse: A combination of salt dissolved in warm water can help fight the underlying cause of the pain.
Once you get to the dentist's office, there are a few things that may help relieve your tooth pain:
- Filling: If the tooth has begun to decay, the dentist will replace the decay with a solid material so that bacteria do not continue to spread.
- Root canal: If an infection has reached the center part of the tooth made up of living tissue, the dentist will clean this area out.
- Crown: This is a cap placed over a damaged tooth to prevent spread of decay or infection.
It's important to see a dentist right away if you have:
- Toothache that is very severe or does not improve with medication
- Fever with dental pain
- Problems eating, swallowing or breathing
- Loose adult tooth
- A fractured or knocked-out tooth
FAQs About Toothache
Here are some frequently asked questions about toothache.
What causes toothache?
Toothache is most often caused by tooth decay or cavity. The inside of your tooth, called the pulp, contains nerves and blood vessels that can become irritated and cause the sensation of a toothache. Nerves can be irritated by factors like bacterial toxins, chemicals, trauma, and even inflammatory chemicals produced by your own body in response to an infection.
Do I have a cavity?
Cavities are best diagnosed by your dentist, who can probe your teeth to look for soft spots indicating decay, or use X-rays to look between your teeth . Tooth decay occurs because of breakdown of enamel by acid-generating bacteria, and, if untreated, can progress to cavities. Signs that you may have a cavity include tooth pain after eating or drinking something sweet or hot/cold and visible cavitated lesions.
Can cavities cause jaw pain?
If a cavity has been left untreated for an extended period of time, bacteria can invade the area and begin to spread to adjacent bony tissues, causing significant jaw pain. Jaw pain does not necessarily indicate a tooth cavity, however. One common source of jaw pain that is often incorrectly thought to be related to tooth pathology is temporomandibular disorder.
What causes toothaches at night?
There are several reasons why toothaches can occur or become worse at night. One major reason is that lying flat causes increased blood flow to the head, causing increased pressure on sensitive areas of your teeth. Another reason is that food may still be lodged in between your teeth from your last meal and may cause irritation to the surrounding area. Finally, teeth grinding at night may also cause pain.
Why does toothache cause radiating pain in the sinuses?
The roots and nerves of your top back teeth lie very closely to the maxillary sinuses, which are two large, air-filled spaces under the eyes and adjacent to your nose. As a result, buildup of fluid in the maxillary sinus secondary to inflammation of the sinuses can cause increased pressure and pain to the teeth. Similarly, infection of the upper teeth can cause pain that seems to be stemming from the sinuses.
Questions Your Doctor May Ask About Toothache
To diagnose this condition, your doctor would likely ask the following questions:
- Has your dentist or significant other ever told you that you grind your teeth in your sleep?
- Were you hit or injured anywhere on your face? If so, where?
- Is this tooth on the upper row (maxilla) or lower row (mandible)?
- Do you take good care of your teeth?
The above questions are also covered by our A.I. Health Assistant.
