If you have tooth pain that comes and goes, it usually means something is irritating the tooth, nerve, or surrounding tissues — even if discomfort disappears for a while. Intermittent tooth pain is commonly linked to cavities, cracked teeth, gum disease, grinding, or inflammation inside the tooth, and the problem often worsens over time if left untreated.
Many people assume the issue has “healed” when the pain fades. In reality, fluctuating pain often means the irritation or infection is temporarily calming down before flaring up again. Early treatment is important because problems that start as mild sensitivity can eventually progress into severe pain, infection, abscesses, or even tooth loss.
Why Does Tooth Pain Come and Go?
Teeth do not usually hurt randomly. Pain that appears and disappears is typically a sign that the nerve inside the tooth is being irritated intermittently rather than constantly.
This can happen because:
- Pressure changes inside the tooth temporarily decrease
- Inflammation fluctuates throughout the day
- Certain triggers only activate the pain occasionally
- Infection may partially drain, reducing pressure temporarily
- Heat, cold, sugar, or biting forces only irritate the tooth at certain times
In early stages, the nerve may still be alive and capable of calming down between flare-ups. As the condition progresses, the pain often becomes more frequent, more intense, and eventually constant.
Common Causes of Tooth Pain That Comes and Goes
Tooth Decay and Cavities
Cavities are one of the most common causes of intermittent tooth pain.
As bacteria break down enamel, the inner layers of the tooth become exposed. Early decay may only cause sensitivity when eating sweets, drinking cold beverages, or chewing. Once the decay gets closer to the nerve, pain episodes become less predictable.
Signs cavity-related pain may be developing include:
- Sensitivity to cold or sweets
- Pain that lingers briefly after eating
- Occasional throbbing
- Pain that worsens at night
- Visible dark spots or holes in the tooth
Untreated decay can eventually lead to irreversible nerve damage on an abscess requiring root canal treatment or extraction.
Cracked Teeth or Fractured Fillings
A small crack in a tooth can create a sharp pain that only happens during certain movements.
When you bite down, the crack may slightly open and irritate the nerve inside the tooth. Once pressure is released, the pain disappears, making it feel inconsistent.
Cracked teeth are commonly caused by:
- Teeth grinding or clenching
- Chewing ice or hard foods
- Trauma to the mouth
- Large old fillings weakening the tooth
- Sudden temperature changes
Cracks are often difficult to see without dental imaging or specialized testing. Unfortunately, they usually worsen over time if untreated.
Reversible vs Irreversible Pulpitis
The pulp is the soft tissue and nerve inside your tooth. When it becomes inflamed, the condition is called pulpitis.
Reversible Pulpitis
In the early stage, inflammation may still be mild enough for the tooth to recover once the cause is treated.
Symptoms often include:
- Short sharp pain to cold or sweets
- Sensitivity that fades quickly
- Mild intermittent discomfort
At this stage, a filling or restoration may save the tooth completely.
Irreversible Pulpitis
If inflammation continues, pressure builds inside the tooth and damages the nerve permanently.
Symptoms may include:
- Spontaneous pain
- Throbbing episodes
- Pain that wakes you up
- Heat sensitivity
- Lingering pain after triggers are removed
Once the pulp becomes irreversibly inflamed, root canal treatment or extraction is usually required.
Teeth Grinding and Clenching (Bruxism)
Many people grind or clench their teeth without even realizing it, especially during sleep.
Constant pressure on the teeth and jaw can irritate the ligaments and nerves surrounding the teeth, creating pain that feels inconsistent or difficult to pinpoint.
Common symptoms include:
- Aching teeth in the morning
- Jaw tightness
- Headaches
- Tooth sensitivity
- Pain that shifts between teeth
Grinding can also contribute to cracks, worn enamel, and TMJ problems.
Gum Disease and Gum Recession
Gum inflammation can sometimes mimic tooth pain.
When gums recede, the sensitive root surface becomes exposed. Cold air, drinks, sweets, or brushing can trigger sudden sharp discomfort that quickly fades.
More advanced gum disease may also create:
- Swollen gums
- Bleeding during brushing
- Bad breath
- Tooth mobility
- Pressure discomfort when chewing
Unlike cavities, gum disease can remain relatively painless until significant damage has already occurred.
Can Tooth Pain Come From Something Other Than a Tooth?
Yes — although less common, some tooth pain is not actually caused by the tooth itself.
Certain nerve disorders, sinus infections, jaw joint disorders, muscle pain, facial pain conditions, and even certain developmental dental anomalies can mimic dental pain or create unusual sensitivity patterns. Persistent pain without obvious dental findings may require further investigation.
Some people are born with structural or developmental differences in their teeth that may increase the risk of sensitivity, bite issues, nerve irritation, or recurrent dental problems later in life.
Trigeminal Neuralgia
Trigeminal neuralgia is a nerve disorder that can create a sudden stabbing or electric shock-like pain in the face or teeth.
This pain is often:
- Sharp or shooting
- Triggered by touch or movement
- Brief but intense
- Difficult to localize
Because the symptoms can resemble dental pain, some patients undergo unnecessary dental treatment before receiving the correct diagnosis.
Persistent Idiopathic Dentoalveolar Pain (PIDAP)
PIDAP refers to ongoing tooth or facial pain without an obvious dental cause.
Unlike typical toothaches, this pain often:
- Persists despite treatment
- Does not improve after fillings or root canals
- Feels dull, aching, or heavy
- May involve multiple teeth
This type of pain is uncommon, but it highlights why accurate diagnosis matters before irreversible dental procedures are performed.
Warning Signs You Should Not Ignore
Some symptoms suggest a dental infection or serious problem requiring prompt treatment.
Contact a dentist immediately if you have:
- Swelling in the face or gums
- Fever
- Severe throbbing pain
- Pain that wakes you from sleep
- Bad taste or pus drainage
- Difficulty chewing
- Pain lasting longer than 1-2 days
- Trouble opening your mouth
- Sensitivity that is worsening rapidly
Dental infections can spread beyond the tooth and become serious if ignored.
How Dentists Diagnose Intermittent Tooth Pain
Finding the source of intermittent pain can sometimes be challenging because symptoms may not be present during the appointment.
A dentist may use:
- Dental x-rays
- Bite testing
- Cold sensitivity testing
- Percussion testing
- Gum measurements
- Evaluation of existing fillings or crowns
- Assessment for grinding or TMJ issues
In more complex cases, additional imaging or referral to a specialist may be recommended.
Treatment for Tooth Pain That Comes and Goes
Treatment depends entirely on the underlying cause.
Possible treatments include:
| Cause | Common Treatment |
| Small cavity | Filling |
| Cracked tooth | Crown or bonding |
| Irreversible pulpitis | Root canal |
| Gum disease | Deep cleaning or periodontal therapy |
| Grinding/clenching | Night guard |
| Infection/abscess | Root canal or extraction |
| Exposed roots | Desensitizing treatment or fluoride |
| Non-dental pain | Referral for further evaluation |
Pain medication may temporarily reduce symptoms, but it does not eliminate the underlying problem.
Can A Toothache Go Away On It’s Own?
Minor irritation can occasionally resolve on its own, especially if the discomfort was caused by temporary gum irritation or mild sensitivity.
However, true tooth pain that repeatedly returns usually indicates an underlying issue that still exists.
A disappearing toothache can sometimes actually be a bad sign. In some cases, the nerve inside the tooth dies completely, causing the pain to suddenly stop before infection develops further.
How to Reduce Tooth Pain at Home Temporarily
Home remedies may provide short-term relief while waiting to see a dentist.
You can try:
- Warm saltwater rinses
- Cold compresses on the outside of the face
- Over-the-counter pain relievers if medically appropriate
- Avoiding very hot, cold, or sugary foods
- Avoid chewing on the painful side
- Using toothpaste for sensitive teeth
Important note: These measures may provide relief, but do not treat the underlying cause.
Final Thoughts on Tooth Pain That Comes and Goes
Tooth pain that comes and goes should not be ignored simply because it is inconsistent. Intermittent symptoms are often an early warning sign of decay, nerve inflammation, cracks, gum disease, grinding, or infection.
The earlier the problem is identified, the more conservative and predictable treatment usually becomes. Waiting for the pain to become constant can allow the damage to progress significantly.
If you are experiencing recurring tooth pain, a dental examination is the safest way to determine what is actually causing it before the condition worsens.
