It is always important to sort out what is going on so that I can provide the right treatment to the right tooth.

The Complexity of Tooth Pain: Why Location Is Unclear

The confusing nature of dental pain:

At times my patients come to see me because of pain, but they find it difficult to tell where the pain is coming from.

What Patients Experience:

Common descriptions:

⚠ “I know it’s the left side, but I can’t tell which tooth” ⚠ “It feels like it’s coming from everywhere” ⚠ “I think it’s the upper tooth, but maybe it’s the lower one” ⚠ “The pain is in my ear/eye/jaw—is it even a tooth?” ⚠ “It was definitely this tooth yesterday, but today it feels like another one”

The frustration: Patients feel they should know which tooth hurts—it’s their mouth, after all—yet the pain remains maddeningly vague, shifting, and difficult to localize.

The Radiation Phenomenon:

Tooth pain can radiate to adjacent teeth, opposing teeth, the head, the eye or the ear.

Where Dental Pain Travels:

Common radiation patterns:

✓ Adjacent teeth (next-door neighbors—upper molar pain felt in premolar) ✓ Opposing teeth (upper tooth pain felt in lower tooth directly opposite, or vice versa) ✓ The head (temple, forehead—upper tooth pain radiating upward) ✓ The eye (upper teeth, especially canines—pain referring to eye socket) ✓ The ear (lower molars especially—pain mimicking earache) ✓ Jaw joint (TMJ) (muscle pain, joint dysfunction—feeling like tooth pain) ✓ Neck (tension, muscle pain—radiating from dental source)

The confusion: Pain originating in one tooth but perceived in distant location—patient pointing to wrong area while actual problem tooth feels fine.

Glen Iris patients often report seeing their GP or ENT specialist for “ear pain” or “sinus pain” before discovering the source was actually a dental infection.

The Multiple Causes of Tooth Pain

Why diagnosis is complex:

The reason why it is occasionally difficult to pinpoint the origin of tooth pain is because it can result from an infection in the tooth itself, or of the gum, or even from clenching and grinding the teeth together, called bruxism or from trauma.

Cause 1: Infection in the Tooth Itself

Pulpal pathology:

How Tooth Infection Develops:

The decay pathway:

1. Bacteria penetrate enamel (cavity forming—outer layer breached)
2. Dentin invasion (bacteria reaching softer inner layer—advancing toward pulp)
3. Pulp exposure (bacteria entering nerve chamber—infection established)
4. Pulpitis (nerve inflammation—reversible or irreversible)
5. Necrosis (nerve death—infection spreading to root tip)
6. Abscess (bone infection—pus accumulation, severe pain)

Symptoms:

Variable presentation:

⚠ Sharp pain (sudden, stabbing—often triggered by stimuli) ⚠ Dull pain (constant aching—throbbing character) ⚠ Constant or intermittent (pain coming and going vs. unrelenting) ⚠ Localized or spread out (pinpointed to tooth vs. entire quadrant) ⚠ Temperature sensitivity (hot or cold triggering pain—hallmark of pulpal involvement) ⚠ Pressure sensitivity (biting, chewing—worsening pain)

The challenge: Same tooth infection can present with vastly different symptoms depending on inflammation stage, patient pain threshold, and anatomical factors.

Cause 2: Infection of the Gum

Periodontal pathology:

How Gum Infection Develops:

The bacterial accumulation pathway:

1. Plaque accumulation (bacterial film coating teeth—at gum line especially)
2. Calculus formation (mineralized plaque—tartar below gums)
3. Gum inflammation (gingivitis—red, swollen, bleeding gums)
4. Pocket formation (gum detaching from tooth—creating space for bacteria)
5. Bone involvement (periodontitis—infection spreading to supporting bone)

The Spreading Characteristic:

While the bacterial accumulation around the tooth leads to a gum inflammation that has a tendency to spread to the surrounding bone.

Why gum infection spreads:

⚠ No barrier (bacteria in pocket directly contacting bone—nothing stopping progression) ⚠ Gravity effect (infection tracking downward—lower teeth more prone) ⚠ Inflammatory mediators (chemicals destroying bone—body’s own response causing damage)

Symptoms:

Periodontal pain characteristics:

⚠ Dull, aching (not sharp like pulpal pain—more constant) ⚠ Worse with pressure (biting, chewing—stressed periodontal ligament) ⚠ Swelling (gum puffiness—possibly facial swelling) ⚠ Pimple on gum (draining abscess—releasing pus) ⚠ Tooth mobility (loosening—bone loss reducing support)

The diagnostic confusion: Periodontal abscess vs. endodontic abscess—both cause pain, swelling, but different treatments needed (deep cleaning vs. root canal).

Cause 3: Bruxism (Clenching and Grinding)

Muscle and joint pain:

Or even from clenching and grinding the teeth together, called bruxism:

What Is Bruxism?

✓ Teeth grinding (sliding teeth back and forth—usually during sleep) ✓ Teeth clenching (jaw muscles contracting—holding teeth together forcefully, often daytime) ✓ Often unconscious (patient unaware—happens during sleep or stress)

How Bruxism Causes Pain:

⚠ Muscle fatigue (masseter, temporalis muscles—overworked, sore) ⚠ TMJ stress (joint compressed—inflammation, disc displacement) ⚠ Tooth trauma (excessive forces—periodontal ligament inflammation, microfractures) ⚠ Referred pain (muscle trigger points—pain perceived in teeth despite teeth being healthy)

Symptoms:

Bruxism-related pain:

⚠ Morning jaw soreness (muscles fatigued from nighttime grinding) ⚠ Headaches (temple area—muscle tension) ⚠ Ear pain (TMJ proximity to ear—referred pain) ⚠ Multiple teeth sensitive (generalized—not localized to single tooth) ⚠ Tooth wear (flattened cusps—evidence of grinding)

The misdiagnosis risk: Patient (and dentist) thinking tooth is problem when actually muscle/joint causing referred pain—treating tooth won’t help.

Cause 4: Trauma

Injury-related pain:

Or from trauma:

Types of Dental Trauma:

⚠ Acute injury (blow to mouth—sports, accident, fall) ⚠ Chronic microtrauma (repetitive stress—nail biting, pen chewing, ice chewing) ⚠ Iatrogenic trauma (dental treatment—recent filling, crown placement)

How Trauma Causes Pain:

⚠ Periodontal ligament inflammation (tooth “bruised”—ligament stressed, inflamed) ⚠ Pulp damage (nerve injured—even without visible tooth damage) ⚠ Fracture (cracked tooth—bacteria entering, nerve exposed)

Symptoms:

Trauma pain characteristics:

⚠ Pressure sensitivity (biting, tapping tooth—sharp pain) ⚠ Recent injury history (even minor bump—patient may not connect to current pain) ⚠ Localized to single tooth (usually—unless multiple teeth injured)

The Diagnostic Challenge:

Each one of the possible causes can lead to a different kind of pain:

Why this matters:

✓ Different causes → different symptoms ✓ Different symptoms → different diagnosis ✓ Different diagnosis → different treatment

Getting diagnosis wrong = treating wrong problem = pain persists (or worsens).

It is always important to sort out what is going on so that I can provide the right treatment to the right tooth.

The Neurological Reality: Why Pinpointing Is Hard

Understanding pain perception:

The Nerve Fiber Problem:

There are nerve fibers that convey pain, but there are no nerves that pinpoint, “it’s this tooth right here”:

How Dental Nerves Work:

The anatomical reality:

✓ Sensory nerve fibers present (detecting pain, temperature, pressure) ⚠ No individual “tooth labels” (nerves don’t transmit “lower left first molar hurts”—just transmit “pain from this general area”) ⚠ Convergent pathways (multiple teeth sharing same nerve trunk—signals mixing)

Since one single nerve conveys the pain sensation from several areas:

The trigeminal nerve branches:

✓ Ophthalmic branch (V1): Upper face, forehead, eye ✓ Maxillary branch (V2): Upper teeth, cheek, nose, upper lip ✓ Mandibular branch (V3): Lower teeth, lower lip, chin, jaw

Within each branch: One nerve fiber may carry signals from 3-4 teeth—brain receiving mixed message.

How the Brain Interprets Pain:

And the brain tries to figure out the source of pain:

The brain’s challenge:

⚠ Incomplete information (pain signal without precise location data) ⚠ Must deduce source (using available clues—not getting direct answer) ⚠ Creates “best guess” (may be correct, may be wrong)

The Clues the Brain Uses:

Using information what we see or feel:

The brain’s detective work:

✓ Visual information (“a brown patch that we see in the mirror”—visible cavity suggesting source) ✓ Tactile feedback (“a tooth that feels different when we test it with the tongue or finger”—texture change indicating problem) ✓ Surface irregularity (“a tooth that feels rough or fractured”—broken edge suggesting pain source) ✓ Recent treatment memory (“a tooth that was treated with a filling and the dentist said that it may need a root canal treatment”—connecting pain to known vulnerable tooth)

The Brain’s Conclusion:

Once the brain reaches a conclusion it will provide you with a location where the pain is:

Confident (but possibly wrong) localization:

✓ Brain assembles clues → forms hypothesis → presents as “this is the tooth” ⚠ Patient feels certain about location—subjectively convinced ⚠ But conclusion may be objectively wrong—based on incomplete/misleading data

When the Brain Can’t Decide:

Or at times it cannot find the source and then it will feel as a dull pain:

Vague, diffuse pain:

⚠ No specific localization (entire quadrant, whole side—can’t narrow down) ⚠ Dull character (not sharp, localized—reflecting brain’s uncertainty) ⚠ Frustrating for patient (can’t point to problem—feels helpless)

The Red Herring Phenomenon: When the Brain Is Wrong

Mislocalization:

But at times the location the brain has deducted is wrong, and the reason too:

What Is a “Red Herring”?

The misleading clue:

✓ Definition (in detective stories): False clue leading investigator astray ✓ In dentistry: Patient confidently identifying wrong tooth/wrong cause—based on brain’s mistaken conclusion

An example is when the person points for the wisdom tooth, when it is not there:

The phantom tooth phenomenon:

⚠ Patient certain pain from wisdom tooth ⚠ Examination reveals wisdom tooth extracted years ago—doesn’t exist ⚠ Actual source: Adjacent molar, opposing tooth, or TMJ—pain referred to wisdom tooth area

Why Red Herrings Occur:

Sources of mislocalization:

⚠ Referred pain (actual problem tooth referring pain to distant tooth—brain mistaking referred location for source) ⚠ Muscle pain (TMJ, muscle trigger points—mimicking tooth pain perfectly) ⚠ Memory bias (previous problem in area—brain assuming same tooth problematic again) ⚠ Visible but unrelated findings (seeing brown spot on tooth, assuming it’s cause—when actually painless stain, real cause elsewhere)

How Common Are Red Herrings?

This phenomenon is called a “Red herring” and it is quite common:

Frequency:

✓ Very common (experienced dentists encounter regularly—daily in busy practices) ✓ Not patient’s fault (neurological reality—not ignorance or exaggeration) ✓ Understandable mistake (brain doing best with limited information)

Glen Iris patients should never feel embarrassed about “wrong” pain location—it’s a predictable neurological phenomenon, not a personal failing.

Dr. Kaufman’s Systematic Diagnostic Approach

Comprehensive examination:

This among other is the reason that when I test for the source of pain I check all possible sources of pain:

Step 1: Comprehensive Tooth Testing

Including teeth on both sides of the same jaw and the opposing one as well:

Why testing beyond the “painful area”:

✓ Adjacent teeth (may be actual source—pain referred to neighbor) ✓ Same jaw, several teeth away (pain radiating along nerve branch) ✓ Opposing arch (upper tooth problem perceived in lower, or vice versa)

Testing methods:

✓ Percussion (tapping teeth—checking for periodontal ligament inflammation) ✓ Palpation (pressing gum tissue—identifying swelling, tenderness) ✓ Thermal testing (cold, hot—assessing pulp vitality, health) ✓ Electric pulp testing (electrical stimulation—determining if nerve alive) ✓ Bite test (pressure on cusps—detecting cracks, high restorations) ✓ Transillumination (light through tooth—revealing cracks)

Step 2: Visual Documentation

And I use the camera to take pictures:

Why photography is essential:

✓ Objective documentation (not relying on memory—capturing what’s actually there) ✓ Magnified view (intraoral camera enlarging—seeing details invisible to naked eye) ✓ Patient education (showing patient—helping understand findings) ✓ Comparison over time (baseline images—tracking changes at future visits) ✓ Second opinions (specialist referral—sending images for consultation)

What Dr. Kaufman photographs:

✓ Suspect teeth (all possibilities—not just patient’s indicated tooth) ✓ Restorations (fillings, crowns—checking margins, integrity) ✓ Gum tissue (inflammation, swelling, fistulas) ✓ Occlusion (bite relationship—identifying trauma, wear)

Step 3: Radiographic Examination

Essential imaging:

✓ Periapical X-rays (individual teeth—showing entire tooth including root tip, surrounding bone) ✓ Bitewing X-rays (between teeth—detecting decay, bone levels) ✓ Panoramic X-ray (entire mouth—overview, identifying distant problems) ✓ CBCT (3D imaging—complex cases, hidden pathology)

Step 4: Medical/Dental History Review

Context gathering:

✓ Previous dental work (recent treatment—may be source or clue) ✓ Trauma history (injury weeks/months ago—may now manifesting as pain) ✓ Bruxism indicators (grinding, clenching—muscle pain vs. tooth pain) ✓ General health (sinus infection, neurological conditions—mimicking dental pain)

Step 5: Synthesizing Evidence

Only after I have examined all possible causes do I summarize the evidence and provide the diagnosis:

The diagnostic process:

1. Gather all data (tests, images, history—complete information)
2. Identify patterns (which findings correlate—building picture)
3. Eliminate red herrings (which teeth test normal despite patient suspicion)
4. Converge on source (which tooth shows multiple positive findings)
5. Explain to patient (presenting evidence—showing why this diagnosis)

Why This Systematic Approach Is Essential:

This I found is the only way to reach the source of pain:

The necessity of thoroughness:

✗ Treating patient’s indicated tooth without verification = 50% chance of treating wrong tooth ✗ Treating first abnormal finding without comprehensive exam = missing actual problem ✓ Systematically evaluating all possibilities = accurate diagnosis, correct treatment, pain resolution

Glen Iris patients benefit from Dr. Kaufman’s detective-like approach—may take longer initially, but ensures treating right tooth the first time.

Common Diagnostic Scenarios

Real-world examples:

Scenario 1: The Misidentified Tooth

Patient presentation:

• “My upper right back tooth hurts terribly”
• Points to second premolar

Dr. Kaufman’s findings:

• Second premolar: Normal on all tests
• First molar (next door): Cracked, sensitive to bite test, X-ray showing decay

Diagnosis: First molar fracture—pain referring to premolar Treatment: Crown on first molar—pain resolves

Scenario 2: The Phantom Wisdom Tooth

Patient presentation:

• “My wisdom tooth is killing me”
• Points to back of jaw

Dr. Kaufman’s findings:

• Wisdom teeth extracted 10 years ago (patient forgot)
• Second molar: Deep cavity, positive pulp test
• TMJ tender to palpation

Diagnosis: Second molar pulpitis + TMJ inflammation—pain perceived in wisdom tooth area Treatment: Root canal on second molar + night guard for TMJ—pain resolves

Scenario 3: The Upper-Lower Confusion

Patient presentation:

• “My lower left molar hurts”
• Points to lower first molar

Dr. Kaufman’s findings:

• Lower first molar: Perfectly healthy, all tests normal
• Upper first molar (directly above): Large cavity, severe cold sensitivity

Diagnosis: Upper molar cavity—pain referred to lower arch Treatment: Filling on upper molar—pain resolves

Scenario 4: The Bruxism Masquerade

Patient presentation:

• “All my back teeth hurt on the right side”
• Can’t identify specific tooth

Dr. Kaufman’s findings:

• All teeth test normal (no decay, cracks, gum disease)
• Masseter muscle extremely tender
• Severe tooth wear visible
• Patient reports waking with jaw soreness

Diagnosis: Bruxism—muscle pain mimicking tooth pain Treatment: Night guard, muscle relaxation techniques—pain resolves

When to Seek Professional Evaluation

Don’t diagnose yourself:

Warning Signs Requiring Evaluation:

🚨 Persistent pain (lasting >24 hours—not resolving spontaneously) 🚨 Severe pain (interfering with sleep, eating, daily function) 🚨 Swelling (facial, gum—indicating infection) 🚨 Fever (systemic infection—requires urgent care) 🚨 Difficulty locating pain (vague, radiating—needs professional diagnosis) 🚨 Recent trauma (injury to face, mouth—assessment essential)

What Not to Do:

✗ Self-treating (antibiotics without diagnosis—masking problem, not solving) ✗ Demanding extraction of tooth you think is problem (may be wrong tooth—losing healthy tooth unnecessarily) ✗ Delaying evaluation (hoping pain resolves—infection worsening, spreading) ✗ Accepting “diagnosis” without examination (over-phone, text description—insufficient for accurate diagnosis)
