Common Reasons Why Your Tooth Is Aching
If you’re wondering, “why is my tooth aching?“, the most frequent culprits are often related to your oral health. These include:
- Gum Disease (Periodontal Disease): Infection and inflammation of the gums and supporting structures of the teeth.
- Tooth Decay (Dental Caries): Breakdown of tooth enamel leading to cavities.
- Sensitive Teeth: Exposed dentin causing discomfort to temperature changes and certain foods.
- Bruxism (Teeth Grinding): Involuntary grinding or clenching of teeth, often during sleep.
- Cracked Tooth: Fractures in the tooth structure due to trauma or pressure.
- Tooth Abscess: A pocket of pus caused by a bacterial infection within the tooth or gums.
- Impacted Tooth: A tooth that is blocked from fully erupting through the gum line.
- Pulpitis (Tooth Pulp Inflammation): Inflammation of the soft tissue inside the tooth containing nerves and blood vessels.
In rarer instances, severe infections like Ludwig’s Angina can also manifest as tooth pain.
Gum Disease: An Inflammatory Cause of Tooth Pain
Gum disease, encompassing gingivitis and periodontitis, is a prevalent reason why your tooth might be aching. Gingivitis, the early stage, involves inflammation of the gums, making them appear red, swollen, and tender. Periodontitis, a more advanced stage, extends the infection deeper, affecting the bone and ligaments supporting your teeth.
Both gingivitis and periodontitis can cause varying degrees of tooth pain, from mild soreness to intense throbbing. Increased pain intensity often indicates a progression of the infection.

Tooth Decay: Cavities Leading to Toothaches
Tooth decay, also known as dental caries, is another common answer to “why is my tooth aching?“. It’s a gradual process where the tooth’s enamel, the hard outer layer, is eroded, leading to cavities.
Plaque, a sticky film of bacteria, accumulates on teeth and feeds on sugars and starches from food debris. This bacterial action produces acids that attack the enamel, creating weak spots and eventually holes. As decay progresses through the enamel and reaches the dentin, the middle layer of the tooth, it can trigger sensitivity and pain.
Sensitive Teeth: Exposed Dentin and Discomfort
Tooth sensitivity is a frequent cause for “why teeth are aching,” especially when exposed to certain triggers. It arises when the dentin, normally protected by enamel and gums, becomes exposed. This exposure can result from:
- Cavities
- Worn-down fillings
- Receding gums, exposing the tooth root
- Cracked teeth
Sensitive teeth typically react with a sharp, sudden pain when encountering stimuli like cold air, hot or cold beverages, sweet or acidic foods, or even brushing.
Bruxism: Teeth Grinding and Aching Teeth
Bruxism, or teeth grinding, is an often unconscious habit that can occur both while awake and asleep. This constant pressure and friction can be a significant factor in “why your teeth are aching,” leading to several dental issues over time, including:
- Increased tooth sensitivity
- Cracked or fractured teeth
- Pain in teeth, jaw, or face
- Temporomandibular joint disorder (TMJ)
Cracked Tooth: Pain from Fractures
A cracked tooth, resulting from mouth trauma, severe bruxism, or biting on hard objects, can certainly explain “why you have a toothache“. The pain associated with a cracked tooth can vary, often manifesting as:
- Sharp pain when biting or chewing
- Sensitivity to temperature changes
- Discomfort when eating certain foods
Cracked teeth are classified into different types based on the severity and location of the crack, ranging from minor craze lines in the enamel to severe splits extending into the root.
Abscess: Infection and Intense Tooth Pain
A dental abscess is a serious condition and a significant reason for asking “why is my tooth aching so badly?“. It’s a localized infection, typically caused by untreated cavities or pulpitis, where bacteria accumulate in the tooth’s pulp chamber. The infection often spreads from the tooth root to the surrounding tissues.
A tooth abscess is characterized by intense, throbbing pain, swelling, and can sometimes be accompanied by fever. The infected area attempts to drain, causing pressure and significant discomfort.

Impacted Tooth: Eruption Issues and Toothaches
An impacted tooth is one that is unable to fully emerge into its proper position in the mouth. Wisdom teeth, being the last to erupt, are frequently impacted due to lack of space. Impacted teeth can be responsible for “why your jaw and tooth are aching“, causing:
- Pressure and discomfort
- Pain, ranging from dull to sharp
- Swelling around the affected area
Infected impacted wisdom teeth can lead to severe pain, fever, gum inflammation, and difficulty swallowing.
Pulpitis: Inflammation Within the Tooth
Pulpitis, inflammation of the tooth pulp, is another key reason behind “why your tooth is aching“. The pulp contains nerves and blood vessels, making it highly sensitive. Pulpitis can be triggered by:
- Tooth decay reaching the pulp
- Trauma to the tooth
- Repeated dental procedures on a single tooth
Pulpitis can be reversible or irreversible. Reversible pulpitis causes brief pain that subsides quickly after the trigger is removed. Irreversible pulpitis, however, results in lingering pain, often lasting minutes after the trigger is gone, and can even cause spontaneous pain without any apparent trigger.
Ludwig’s Angina: A Rare but Serious Infection
Ludwig’s Angina is a rare, but life-threatening bacterial infection occurring under the tongue. While less common, it’s crucial to be aware of it when considering “why is my tooth aching and I feel unwell?“. It can arise from mouth trauma or a tooth abscess and demands immediate medical attention.
Symptoms of Ludwig’s Angina, in addition to tooth pain, include:
- Fever
- Swollen tongue, potentially protruding from the mouth
- Difficulty swallowing or speaking, drooling
- Neck swelling, pain, and redness
- Weakness, fatigue, and confusion
- Earache
This infection can spread rapidly and obstruct the airway, causing breathing difficulties. It can also lead to sepsis and septic shock. Seek emergency medical help immediately if you suspect Ludwig’s Angina, especially if you experience breathing changes.
Diagnosing the Cause of Your Tooth Pain
To accurately determine why your tooth is aching, a dentist will employ a comprehensive diagnostic approach involving medical history, physical examination, and imaging techniques.
Medical History Assessment
The dentist will start by asking detailed questions about your tooth pain symptoms, such as:
- Location of the pain
- Factors that worsen or alleviate the pain
- Duration of the pain
- Presence of other symptoms like swelling or fever
Physical Examination
A physical examination allows the dentist to visually assess your mouth and face for signs of swelling and infection. The oral exam involves:
- Intraoral Exam (inside the mouth): Checking for swelling, decay, broken teeth, and lesions on soft and hard tissues.
- Extraoral Exam (outside the mouth): Assessing swelling, pain distribution, jaw movements, TMJ sounds, and myofascial pain.
For concerning symptoms like fever or neck pain, a cranial nerve exam may be performed to evaluate the head and neck region.
Imaging and Diagnostic Tests
Dental X-rays are often essential to diagnose why your tooth is aching, helping to identify abscesses, cavities, or other hidden problems.
In cases where rare conditions like Ludwig’s Angina are suspected, a CT scan or MRI may be necessary.
Other diagnostic tests can include:
- Vitality Testing (Pulp Test): Using cold or electrical stimuli to assess pulp health.
- Bite Test: To pinpoint cracked teeth by evaluating pain response to pressure.
ENT Evaluation for Non-Dental Tooth Pain
Sometimes, “why your tooth is aching” has nothing to do with dental issues. Conditions like sinus infections can radiate pain to the mouth or cause tooth sensitivity. TMJ dysfunction can also manifest as toothache-like pain that worsens with jaw movement.
If your dentist suspects a non-dental cause, they may refer you to an Ear, Nose, and Throat (ENT) specialist for further evaluation.
Tooth Pain Treatment Options
Treatment for why your tooth is aching is directly dependent on the underlying cause. Options range from medications and rinses to dental procedures. Early intervention is crucial to prevent complications and worsening conditions.
Medications for Toothache Relief
Your dentist may recommend or prescribe medications to manage tooth pain and address underlying issues:
- Pain Relief: Over-the-counter pain relievers like acetaminophen (Tylenol) or NSAIDs such as ibuprofen (Advil) or naproxen (Aleve) are often recommended for pain management.
- Antibiotics: For infections like abscesses, pulpitis, or gum disease, antibiotics such as amoxicillin or clindamycin may be prescribed.
Oral Rinses and Topical Fluoride
Oral rinses play a supportive role in treating certain causes of toothache:
- Chlorhexidine Rinse: Reduces bacteria in the mouth and may be used for gingivitis.
- Fluoride Rinses: Help prevent and treat tooth decay and gum disease.
For sensitive teeth, dentists may apply topical fluoride treatments and recommend using fluoride toothpaste formulated for sensitive teeth.
Oral Devices for Bruxism-Related Tooth Pain
If bruxism is contributing to “why your teeth are aching,” especially at night, a dentist may recommend an oral device like a mouthguard. While over-the-counter mouthguards are available, custom-fitted guards from your dentist offer greater comfort and durability. Mouthguards protect teeth from grinding damage but don’t address the underlying bruxism triggers, which may include stress, anxiety, and anger management issues.
Dental Procedures to Address Toothache Causes
Several dental procedures are used to treat the root causes of tooth pain:
- Tooth Decay and Cavities: Removal of decayed tooth structure followed by filling placement.
- Irreversible Pulpitis: Root canal therapy to remove infected pulp, typically followed by crown placement.
- Abscess: Incision and drainage of the infected pocket.
- Cracked Tooth: Treatment depends on crack severity and location, ranging from fillings or root canals to extraction and replacement.
At-Home Toothache Relief Measures
While waiting for a dental appointment to address “why your tooth is aching,” you can try these at-home remedies for temporary relief:
- Clove Oil: Dilute a few drops of clove oil with olive oil and apply to the affected gum area using a cotton ball for 5-10 minutes. Eugenol in clove oil has anesthetic and anti-inflammatory properties.
- Ice Pack: Apply an ice pack or frozen vegetable bag wrapped in a cloth to the outside of your jaw for 20 minutes at a time, repeated as needed.
- Salt Water Rinse: Rinse your mouth with warm salt water (1/2 teaspoon salt in 8 ounces of water) or diluted hydrogen peroxide (1:1 ratio) for 30 seconds, then spit out.
- Over-the-Counter Pain Relievers: Use acetaminophen (Tylenol), ibuprofen (Advil), or naproxen (Aleve) as directed on the packaging.
Preventing Tooth Pain: Proactive Oral Care
Preventing tooth pain starts with consistent and effective oral hygiene practices. To minimize the chances of asking “why is my tooth aching” due to preventable issues, adopt these habits:
- Brush your teeth gently twice daily with fluoride toothpaste.
- Floss daily to remove plaque and food particles from between teeth.
- Use fluoridated water when possible to strengthen enamel.
- Schedule regular dental cleanings and check-ups.
- Avoid smoking, which increases the risk of gum disease.
- Steer clear of habits that can damage teeth, like chewing on hard objects or using teeth to open things.
When to Seek Dental Care for Tooth Pain
While home remedies can provide temporary relief, it’s crucial to know when to seek professional dental help for “why your tooth is aching“. Schedule a dental appointment if:
- You experience intense tooth pain.
- You have a fever along with toothache.
- You have a broken, cracked, loose, or knocked-out tooth.
- You notice a cavity or hole in your tooth.
- Your face or mouth is swollen.
