Tooth pain is discomfort or soreness in or around a tooth caused by decay, infection, damage, or gum disease. Our emergency dentist evaluates the source of your pain and provides prompt, effective treatment to protect your smile and overall oral health. Treating tooth pain stops the spread of infection, relieves persistent discomfort, and keeps your teeth and gums healthy for a lifetime.
At Pasadena Dental Office and Orthodontics, our emergency dentist evaluates tooth pain using digital X-rays and intraoral imaging to identify the exact cause, whether it involves deep decay, abscess, periodontal disease, cracked enamel, or exposed pulp. Depending on the diagnosis, treatment options include composite fillings for cavities, fluoride or bonding agents for sensitivity, scaling and root planing for gum infection, or root canal therapy followed by a permanent crown when the pulp is affected. Acting quickly helps ease pain, stop infection before it spreads to surrounding bone or tissue, and prevent the need for extraction. If you are experiencing persistent tooth pain, contact our office for a same-day emergency appointment.
A toothache is pain or discomfort originating from within or around a tooth. It is a signal from the nerve inside the tooth that something is affecting the tooth’s health or integrity.
Toothaches can develop for many different reasons. Identifying the cause is important because the correct treatment depends on the underlying problem.
Common causes include:
About 12% of adults report experiencing a toothache within six months.
Tooth pain near a dental crown can happen for several reasons, including decay forming underneath the crown, a loose crown, gum recession around the tooth, or pressure from teeth grinding. In some cases, the tooth underneath the crown may be irritated or infected, especially if the crown no longer seals the tooth properly. Pain near a crown should be evaluated promptly so the problem does not worsen or lead to further damage.
Tooth pain near a filling may happen if the filling is loose, cracked, too high when you bite, or if new decay has formed around the restored tooth. Some mild sensitivity after a recent filling can be temporary, but lingering pain, sharp discomfort, or pain when biting may indicate that the tooth needs further evaluation. If discomfort continues, your dentist may need to adjust or replace the filling or determine whether deeper treatment is necessary.
Tooth pain near the gum is often related to gum inflammation, gum disease, exposed tooth roots, or infection near the base of the tooth. Plaque buildup around the gumline can irritate the tissue and make the area feel sore, swollen, or sensitive. In more advanced cases, an abscess or periodontal infection may develop and require immediate treatment to protect the tooth and surrounding bone.
Pain near the gum line may mean the tooth root is exposed, the gums are receding, or bacteria have collected where the tooth and gum meet. This type of discomfort is commonly triggered by hot or cold foods, brushing, or pressure on the area. Tooth pain near the gum line can also be an early sign of gum disease or tooth decay developing close to the root surface, so a dental exam is important to identify the cause.
Tooth pain does not always feel the same. The type of pain you experience can often help a dentist identify the underlying cause.
A dull, ongoing ache is often associated with tooth decay, teeth grinding, or food stuck between teeth. This type of pain tends to linger throughout the day and may worsen gradually if the underlying issue is not treated.
Throbbing pain is commonly linked to infection or an abscess. This type of toothache may pulse with the heartbeat and often becomes more intense over time. Swelling, fever, or gum tenderness may also occur with this type of pain.
Sharp pain that appears suddenly when biting or chewing may indicate a cracked tooth or loose dental filling. The pain may come and go depending on pressure placed on the tooth.
Pain triggered by hot coffee, cold drinks, or sweets is often caused by enamel erosion, exposed dentin, or gum recession. This sensitivity can also develop after dental procedures or from early stages of tooth decay.
Pain when applying pressure while chewing may indicate a cracked tooth, damaged filling, or infection in the tooth root. The discomfort often disappears when pressure is released.
Sometimes tooth pain spreads to the jaw, ear, or surrounding facial areas. This can occur with impacted wisdom teeth, severe infection, or temporomandibular joint (TMJ) issues.
Swelling around the gums near the tooth root often signals infection or abscess formation. This type of pain is usually accompanied by redness, tenderness, and sometimes pus drainage.
Tooth pain near a wisdom tooth is often caused by eruption problems, impaction, infection, or inflammation of the gum tissue around the back molars. Wisdom teeth may push against nearby teeth or become partially trapped beneath the gums, which can create pressure, swelling, and difficulty chewing. Because wisdom tooth problems can worsen quickly, persistent discomfort in the back of the mouth should be examined as soon as possible.
Tooth pain near the jaw may come from a dental infection, impacted wisdom tooth, teeth grinding, or TMJ-related strain. Sometimes pain from a tooth spreads into the lower jaw and makes it difficult to chew or open the mouth comfortably. Jaw discomfort that occurs with swelling, fever, or severe tooth pain should be treated quickly to rule out infection or other serious dental problems.
Tooth pain near the ear can sometimes be caused by an infected molar, wisdom tooth pressure, jaw joint dysfunction, or nerve-related referred pain. Because the mouth, jaw, and ear are closely connected, pain from one area can be felt in another. If ear-area discomfort happens along with tooth sensitivity, swelling, or pain when chewing, a dental exam can help determine whether the source is oral rather than medical.
Tooth pain near the sinus area may be caused by either a sinus infection or a dental issue involving the upper back teeth. The roots of the upper molars sit close to the sinus cavity, so inflammation or pressure in the sinuses can sometimes feel like tooth pain. In other cases, an infected upper tooth can create discomfort that seems centered in the cheek or sinus area. A proper evaluation can help determine whether the problem is dental, sinus-related, or both.
Tooth pain near the nose is sometimes associated with sinus pressure, especially when discomfort affects the upper front teeth or the area beside the nose and cheek. Sinus inflammation can create pressure that feels similar to dental pain, even when the teeth themselves are healthy. However, if the pain is isolated to one tooth or is accompanied by swelling, sensitivity, or gum irritation, a dental cause may still be involved and should be checked.
Symptoms of a toothache vary depending on the source of the problem. Common symptoms include:
Tooth pain treatment depends on the cause of the problem. We will identify the source of the pain and recommend the most effective treatment to eliminate discomfort and restore oral health.
Dental fillings are recommended when tooth pain is caused by decay or a cavity that has damaged the outer layers of the tooth. The decayed portion is removed, and the area is filled with a durable material to stop pain, protect the tooth, and restore normal function in a straightforward dental treatment.
When tooth pain is caused by infection or inflammation inside the dental pulp, root canal therapy removes the damaged nerves and blood vessels, cleans the inside of the tooth, and seals it to prevent further infection. This treatment relieves pain, helps save the natural tooth, and is often followed by a dental crown for added protection.
When a tooth has a large crack, deep cavity, or weakened structure causing pain, a dental crown may be placed over the visible portion of the tooth to strengthen it and restore biting function. Crowns are often recommended when the tooth cannot be protected with a filling alone and needs full coverage to prevent further damage.
When a tooth is too decayed, fractured, or infected to be saved, tooth extraction may be the best option to stop pain and protect the surrounding teeth and bone. Removing the damaged tooth can also prevent the infection from spreading, and replacement options such as a dental implant or bridge may be discussed afterward.
When tooth pain is caused by a dental abscess, treatment may involve draining the infection to reduce pressure, relieve discomfort, and remove harmful bacteria. Abscess treatment is often combined with additional care, such as root canal therapy or extraction, depending on the severity of the infection.
If tooth pain is linked to gum disease or infection below the gumline, scaling and root planing may be recommended to remove plaque, tartar, and bacteria from around the roots of the teeth. This deep cleaning treatment helps reduce inflammation, support gum healing, and address pain caused by periodontal disease.
When tooth pain is caused by exposed roots, worn enamel, or gum recession, desensitizing treatments or dental bonding may be used to protect the sensitive areas of the tooth. These treatments help reduce nerve irritation, ease discomfort from hot or cold foods, and improve everyday comfort.
You should see an emergency dentist as soon as possible if your tooth pain lasts longer than one or two days, becomes severe, or is accompanied by swelling, fever, or difficulty chewing. Persistent tooth pain rarely resolves on its own and often indicates decay, infection, or damage that requires professional treatment. Early diagnosis can prevent more serious dental problems and help preserve the natural tooth.

Yes. A toothache is often a sign of decay, infection, gum disease, or another serious problem that should not be ignored. Even if the pain seems mild at first, it can get worse over time without proper care.
Tooth pain may be an emergency if it is severe, does not go away, or comes with swelling, bleeding, fever, or a headache. In these situations, it is best to go to a dentist right away for evaluation and treatment.
Yes. Sensitive teeth can cause pain when eating or drinking something hot, cold, or sweet. While sensitivity may sometimes be temporary, ongoing discomfort can mean there is an underlying issue causing the pain.
You may be able to ease discomfort temporarily by rinsing with warm salt water, avoiding very hot or cold foods, and taking over-the-counter medication as directed. These options may provide short-term relief, but they do not treat the source of the pain.
Prompt treatment helps your dentist find out what is causing the pain before the condition becomes more severe. Getting care early can also reduce the risk of infection, damage, or more complex treatment later.
