Emergency Tooth Pain, TMJ/Jaw Pain & Sinus Pressure Toothaches: How to Tell the Difference & When to Call Phoenix Dental

Tooth pain can have many causes — some urgent, some related to jaw issues, and others caused by sinus pressure. At Phoenix Dental in Carrollwood/Tampa, we help patients figure out exactly what kind of pain they’re feeling so we can treat the problem quickly and prevent long-term complications.

This guide explains how to differentiate true dental emergencies, TMJ/jaw pain, and sinus-related toothaches, and what to do when symptoms appear.

1. Emergency Tooth Pain

A dental emergency is any kind of tooth pain that involves infection, severe inflammation, or structural damage.

Common Causes of Emergency Tooth Pain

• Deep cavities
• Cracked or fractured teeth
• Abscess or infection
• Failed fillings or crowns
• Gum infection around a tooth
• Severe sensitivity turning into throbbing
• Pain that wakes you from sleep
• Pain that radiates to the ear, eye, or jaw

Symptoms of a True Dental Emergency

• Sharp, throbbing, or constant pain
• Pain that gets worse when lying down
• Severe sensitivity to hot or cold
• Swelling in the gums or face
• Fever or foul taste in the mouth
• Pain when biting down
• A broken or chipped tooth with exposed nerve
• Gum boil or pimple near the tooth

These issues do not get better on their own and require immediate treatment to prevent infection from spreading.

How Phoenix Dental Treats Emergency Tooth Pain

Depending on the cause, treatment may include:

• Removing decay and placing a new filling
• Stabilizing cracks with a crown
• Root canal treatment for infected nerves
• Scaling and drainage for gum infection
• Antibiotics when necessary
• Tooth extraction for non-restorable teeth
• Protective medicated dressings
• Same-day relief treatments

Our goal is to stop the pain fast — then protect your tooth long-term.

2. TMJ / Jaw Pain (Not Always a Tooth Problem)

Not all “tooth pain” comes from the tooth itself. Many patients experience referred pain from the jaw joint (TMJ) or surrounding muscles.

Common Causes of TMJ or Jaw Pain

• Bruxism (nighttime grinding or clenching)
• Stress-related jaw tension
• Bite imbalance
• Trauma or overuse
• Arthritis in the TMJ
• Worn-down teeth from grinding

Symptoms of TMJ-Related Pain

• Soreness in the jaw muscles
• Pain when chewing tough foods
• Ear pain, ringing, or fullness
• Clicking or popping in the jaw joint
• Headaches or temple pressure
• Tooth pain with no dental finding
• Tired jaw when eating
• Difficulty opening wide

TMJ pain often feels like tooth pain, but the tooth itself is healthy.

How Phoenix Dental Treats TMJ / Jaw Pain

• Custom night guards to reduce clenching
• Bite balancing adjustments
• Home-care therapy: heat, massage, stretches
• Anti-inflammatory recommendations
• Monitoring for grinding-related wear
• Identifying stress-related contributors

If TMJ is causing your symptoms, dental procedures alone won’t solve the issue — targeted treatment will.

3. Sinus Pressure Toothaches

Another common source of tooth pain is sinus inflammation, especially during allergies or sinus infections.

Why Sinus Problems Cause Tooth Pain

Your upper back teeth sit very close to the maxillary sinus. When the sinus becomes inflamed or filled with fluid, pressure is placed on the tooth roots.

Symptoms of Sinus-Related Toothache

• Pressure in multiple upper back teeth
• Pain on both sides
• Worse when bending over
• Fullness in cheeks or under eyes
• Congestion or post-nasal drip
• No sharp pain when biting one tooth
• Pain that changes with position

Sinus-related pain typically fluctuates, unlike dental infections that worsen over time.

How Phoenix Dental Helps With Sinus Tooth Pain

We first rule out dental infection. If the teeth are healthy, we recommend:

• Decongestants
• Nasal sprays
• Steam inhalation
• Hydration
• Saline rinses
• Medical evaluation if needed

If symptoms resolve with sinus treatment, the teeth are not the cause.

How to Know Which Pain You Have

‍

If you’re unsure, we can diagnose it quickly and accurately.

When to Call Phoenix Dental Immediately

Call right away if you have:

• Throbbing pain
• Facial swelling
• Fever or chills
• Pain that wakes you up
• Cracked or broken tooth
• Pain after trauma
• Gum swelling or pimple
• Constant sensitivity
• Sudden severe pain

These are signs of infection or a true dental emergency.

Why Urgent Treatment Matters

Delaying care can lead to:

• Worsening infection
• Severe swelling
• Root canal or extraction
• Bone loss
• Abscess formation
• Hospitalization in extreme cases

Early treatment protects both your health and your teeth.
