Tooth pain can be difficult to ignore. A sharp sensation when drinking something cold, a dull ache that seems to linger, or sudden pain when biting down can make ordinary activities uncomfortable. For some patients, dental pain can even interfere with eating, sleeping, working, or concentrating.

One of the most important things to understand about tooth pain is that pain is a symptom, not a diagnosis. The source may be a cavity, damaged enamel, an infection, gum disease, teeth grinding, or another dental condition. Some causes are relatively minor when addressed early, while others can worsen quickly without professional treatment.

At Nuttall Smiles, we provide comprehensive dental care for patients experiencing tooth pain in Auburn, WA. Our team uses clinical examination, digital imaging, and personalized treatment planning to identify the underlying cause and determine the appropriate solution.

Located at 722 12th Street SE Auburn, WA 98002, Nuttall Smiles serves patients throughout Auburn and surrounding communities, including Kent, Federal Way, Pacific, Algona, and Sumner.

If your tooth hurts, understanding what may be happening inside your mouth can help you recognize when professional dental care is necessary.

What Does Tooth Pain Mean?

Tooth pain occurs when nerves or surrounding tissues respond to irritation, inflammation, pressure, infection, or physical damage. The inside of a tooth contains a soft tissue called the dental pulp. This tissue contains nerves and blood vessels. When irritation reaches the pulp, the nerves can transmit pain signals to the brain. However, tooth pain does not always originate inside the tooth itself. Problems involving the gums, jaw, surrounding bone, or bite can also produce discomfort.

The location, duration, and type of pain can provide useful clues.

For example:

• Brief sensitivity to cold may be associated with exposed dentin or early tooth sensitivity.
• Lingering pain after hot or cold exposure may indicate inflammation within the pulp.
• Pain when biting may be associated with a cracked tooth, inflammation around the root, or another structural problem.
• Persistent throbbing pain may indicate significant inflammation or infection.
• Pain accompanied by swelling or fever requires prompt professional evaluation.

Only a dental examination can determine the actual cause.

10 Common Causes of Tooth Pain

1. Tooth Decay and Cavities

One of the most common causes of tooth pain is dental decay. Cavities develop when bacteria in dental plaque metabolize carbohydrates and produce acids. Repeated acid exposure gradually removes minerals from enamel, the hard outer layer of the tooth. Initially, early enamel damage may cause no symptoms. If decay progresses through the enamel and into the underlying dentin, the tooth may become increasingly sensitive. If the decay reaches the pulp, inflammation and significant pain can develop.

What cavity pain may feel like:

• Sensitivity to sweets
• Pain from cold drinks
• Discomfort when chewing
• Increasing sensitivity over time

Early cavities can often be treated with conservative restorative dentistry. Advanced decay may require more extensive treatment, such as root canal therapy or a dental crown.

2. Tooth Sensitivity

Not all tooth sensitivity means you have a cavity. Sensitivity can occur when the protective enamel becomes thinner or when gum recession exposes the underlying dentin. Dentin contains microscopic tubules that communicate with the nerve-containing pulp. When exposed to cold, heat, or other stimuli, these pathways can trigger a brief pain response.

Common causes include:

• Aggressive brushing
• Gum recession
• Enamel erosion
• Tooth grinding
• Acidic foods and beverages
• Certain dental procedures

If sensitivity is persistent or worsening, a dental examination can determine whether there is an underlying problem.

3. Cracked or Fractured Teeth

A cracked tooth can produce pain that is difficult to diagnose because symptoms may come and go. When you bite down, the crack can cause small movements within the tooth structure. This movement may irritate the pulp or surrounding tissues.

Patients may notice:

• Sharp pain when biting
• Pain when releasing a bite
• Sensitivity to cold
• Intermittent discomfort

Treatment depends on the location and severity of the crack. Depending on the situation, treatment may involve bonding, a filling, a crown, or root canal therapy. Severe fractures may require extraction if the tooth cannot be predictably restored.

4. Dental Infection

A dental infection can occur when bacteria reach the pulp and surrounding tissues. An untreated cavity, crack, or dental trauma can provide bacteria with a pathway into the deeper structures of the tooth.

As infection progresses, patients may develop:

• Persistent toothache
• Throbbing pain
• Swelling
• Tender gums
• Bad taste
• Fever
• Facial swelling

A dental infection should not be ignored. Infections can spread beyond the original tooth and affect surrounding tissues. Treatment may involve root canal therapy when the tooth can be saved or extraction when the tooth cannot be restored.

5. Gum Disease

Tooth pain does not always originate from the tooth itself. Gum disease can cause inflammation, tenderness, swelling, and sensitivity around the teeth. Gingivitis is the early stage of gum disease and is generally associated with inflammation caused by plaque buildup. If untreated, periodontal disease can progress into deeper tissues supporting the teeth.

Advanced gum disease can contribute to:

• Gum recession
• Bone loss
• Loose teeth
• Persistent bad breath
• Tooth sensitivity

Professional dental care is important for identifying and treating gum disease before it causes significant structural damage.

6. Wisdom Teeth Problems

Wisdom teeth can cause pain when they do not have enough room to erupt properly. An impacted wisdom tooth may remain partially or completely trapped beneath the gums or develop at an abnormal angle. This can create areas where bacteria and food particles accumulate.

Symptoms may include:

• Pain at the back of the jaw
• Swollen gums
• Jaw stiffness
• Difficulty opening the mouth
• Bad breath
• Recurrent infections

Depending on the tooth's position and condition, wisdom teeth removal may be recommended.

7. Teeth Grinding and Clenching

Bruxism refers to repeated teeth grinding or clenching. Many people grind their teeth during sleep without realizing it. Others clench their jaw during periods of stress or concentration. Repeated pressure can gradually wear down enamel and place excessive forces on teeth and surrounding structures.

Signs may include:

• Morning tooth sensitivity
• Flattened or worn teeth
• Cracked fillings
• Jaw soreness
• Headaches
• Facial tension

A custom dental night guard may help protect teeth from excessive grinding forces. Patients experiencing jaw-related symptoms may also benefit from an evaluation for TMJ-related concerns.

8. Damaged or Loose Dental Restorations

Existing fillings, crowns, bridges, or other restorations can occasionally become damaged or loosen over time. A compromised restoration may expose sensitive tooth structure or allow bacteria to enter around the restoration.

You may notice:

• Sensitivity
• Pain when chewing
• A rough or sharp edge
• Food becoming trapped
• A restoration that feels loose

A dentist can evaluate the restoration and determine whether it can be repaired or should be replaced.

9. Dental Trauma

An accident, sports injury, fall, or impact can damage a tooth even when there is no visible fracture. Trauma can injure the pulp or supporting structures. A tooth may initially appear normal but develop discoloration or pain later. Any significant dental injury should be evaluated promptly, particularly if the tooth becomes loose, changes color, or becomes sensitive. Sports mouth guards can also help reduce the risk of dental injuries during athletic activities.

10. Problems With Your Bite

The way your upper and lower teeth come together affects how chewing forces are distributed. If certain teeth receive excessive pressure, patients may experience discomfort when biting or develop accelerated tooth wear. An uneven bite can also contribute to jaw muscle tension and TMJ symptoms. A comprehensive dental evaluation can help identify whether bite forces are contributing to your symptoms.

When Is Tooth Pain a Dental Emergency?

Some tooth pain requires immediate attention.

Seek prompt dental care if you experience:

• Severe or rapidly worsening tooth pain
• Facial or jaw swelling
• Fever associated with dental pain
• Difficulty swallowing
• Difficulty breathing
• Significant bleeding
• A knocked-out permanent tooth
• A serious dental injury

Facial swelling accompanied by difficulty breathing or swallowing can indicate a potentially serious infection and requires emergency medical attention. Do not rely on pain medication to mask worsening symptoms without addressing the underlying cause.

Why Tooth Pain Should Not Be Ignored

Dental pain can sometimes disappear temporarily without the underlying problem being resolved. For example, an infected tooth may initially cause intense pain. If the pulp becomes severely damaged or dies, the pain may decrease because the nerve is no longer functioning normally. This does not necessarily mean the infection has disappeared. In fact, the infection may continue spreading into surrounding tissues. This is why a reduction in pain is not always a sign that the tooth has healed.

How Nuttall Smiles Diagnoses Tooth Pain

Identifying the cause of tooth pain requires more than simply asking where it hurts. At Nuttall Smiles, diagnosis may involve several steps.

Step 1: Discussing Your Symptoms

Your dentist will ask about:

• When the pain began
• Whether it is constant or intermittent
• What triggers it
• How long the pain lasts
• Whether you have swelling or sensitivity

These details help narrow down potential causes.

Step 2: Clinical Examination

Your teeth, gums, bite, and surrounding tissues are examined for visible signs of disease or damage.

Step 3: Digital Imaging

Dental X-rays or other diagnostic imaging may be used to identify problems below the surface, including decay, infection, bone changes, or issues involving tooth roots.

Step 4: Personalized Diagnosis

Once the cause is identified, your dentist can explain your treatment options and recommend the most appropriate approach.

Treatment Options for Tooth Pain

Treatment depends entirely on the underlying cause. Potential solutions may include:

Dental Fillings

Used to restore teeth affected by cavities.

Composite Dental Bonding

May repair minor chips, cracks, or structural imperfections.

Root Canal Treatment

Used when infection or inflammation affects the pulp and the natural tooth can be saved.

Dental Crowns

Used to protect and restore significantly weakened teeth.

Gum Disease Treatment

Addresses infection and inflammation affecting the supporting tissues.

Wisdom Teeth Removal

Used when impacted or problematic wisdom teeth create oral health concerns.

Tooth Extraction

Considered when a tooth cannot be predictably restored.

Dental Night Guards

May protect teeth from damage associated with grinding and clenching.

Frequently Asked Questions About Tooth Pain

Why does my tooth hurt when I drink something cold?

Cold sensitivity can occur when enamel is weakened or dentin becomes exposed. However, persistent or intense cold sensitivity can also be associated with decay or inflammation inside the tooth.

Why does my tooth hurt when I bite down?

Pain when biting can be associated with a cracked tooth, inflammation around the root, dental infection, or problems with an existing restoration. A dental examination is needed to identify the cause.

Can a cavity cause severe tooth pain?

Yes. As decay progresses toward the pulp, inflammation can cause significant pain and sensitivity.

Can tooth pain go away on its own?

Pain may temporarily disappear, but that does not necessarily mean the underlying problem has resolved. An infected or severely damaged tooth can sometimes become less painful as the nerve deteriorates.

How do I know if I have a tooth infection?

Possible signs include persistent pain, swelling, tenderness, bad taste, fever, or sensitivity. A dentist should evaluate suspected infections promptly.

Should I go to the emergency room for tooth pain?

A dentist is generally the appropriate professional for most dental problems. However, severe facial swelling or difficulty breathing or swallowing can require emergency medical attention.

Can teeth grinding cause tooth pain?

Yes. Repeated grinding and clenching can cause tooth sensitivity, enamel wear, cracks, and jaw discomfort.

Can sedation dentistry help if I am afraid to get my tooth treated?

Patients with dental anxiety may be candidates for sedation dentistry. Your dental team can evaluate your needs and discuss appropriate comfort options before treatment.
