Tooth Pain: What Is Causing It?
Pain is information, not a diagnosis. A tooth that hurts briefly with cold is different from a tooth that throbs at night or hurts when biting.
Illustration for patient education. Actual diagnosis requires Dr. Nguyen’s exam and appropriate imaging.
Why Tooth Pain Can Be Hard to Locate
Dental pain can refer to nearby teeth, the jaw, ear, or sinus area. A patient may point to one tooth, but testing shows a different source. That is why Dr. Nguyen may use digital X-rays, bite testing, cold testing, gum measurements, microscope evaluation, and sometimes CBCT.
Pain Patterns Patients Should Notice
Sharp bite pain may suggest a crack, high filling, or periodontal issue. Lingering cold or heat pain may suggest nerve inflammation. Swelling, bad taste, pus, or a gum pimple may suggest infection.
When CBCT or the Microscope Helps
Cone beam CT can show 3D information when regular X-rays do not explain persistent pain, root anatomy, infection location, or implant-related problems. The Leica microscope helps inspect cracks, old filling margins, and root canal access areas.
How SoftDental Technology Helps
Used when clinically needed to find cavities between teeth, bone changes, infection signs, and failing restorations.
High magnification and illumination help Dr. Nguyen inspect cracks, margins, root canals, and fine tooth details.
3D imaging used selectively for complex diagnosis, implant planning, root anatomy, sinus/nerve location, and difficult infections.
A digital scan that helps patients see tooth position, bite changes, wear, crowding, and orthodontic/restorative planning.
Dr. Nguyen chooses technology based on symptoms, risk, X-ray findings, treatment complexity, and patient safety.
What Patients Should Watch For
Brief cold pain
May be recession, abrasion, cavity, or small crack.
Heat pain
Can signal nerve inflammation or infection.
Bite pain
Often linked to cracks, high bite, or gum support.
Swelling
Needs prompt evaluation.
Quick Comparison
| Symptom | Possible cause | What SoftDental checks |
|---|---|---|
| Cold sensitivity | Recession, abrasion, cavity, crack. | Exam, X-ray, sensitivity tests. |
| Pain when biting | Crack, high filling/crown, abscess. | Bite test, microscope, X-ray. |
| Throbbing/night pain | Pulp inflammation or infection. | Root canal evaluation. |
| Swelling/bad taste | Abscess or drainage. | Urgent exam and imaging. |
What Happens at SoftDental
Describe the pain
Tell us what triggers it, how long it lasts, and where it travels.
Take needed images
Digital X-rays and CBCT are used when clinically appropriate.
Test the tooth
Cold, bite, percussion, gum probing, and microscope inspection may be used.
Treat the cause
Options may include desensitizing care, filling, crown, root canal, gum treatment, or extraction.
Pain that comes and goes can still be serious. The goal is to diagnose the cause before the tooth becomes harder to save.

ADA: Radiographic Imaging — dental radiography should be patient-specific; the ADA notes recommendations for 2-D and CBCT patient selection and states dental imaging is a minor contribution to total radiation exposure.
ADA MouthHealthy: X-rays — dental X-rays emit very low radiation doses and modern tools/techniques are designed to limit exposure.
CDC: About Dental Sealants — dental sealants protect against cavities for many years and are thin coatings applied to chewing surfaces of back teeth.
ADA MouthHealthy: Scaling and Root Planing — scaling and root planing is deep cleaning below the gumline used to treat gum disease.
Cleveland Clinic: Scaling and Root Planing — scaling and root planing removes plaque/tartar above and below gums and smooths roots; soreness/bleeding can occur.
ADA: Oral Cancer — early detection of oral potentially malignant disorders and oral squamous cell carcinoma can improve prognosis; biopsy remains the reference standard.
CDC: Dental Infection Control — dental settings should follow infection prevention practices, including sterilization/disinfection guidance.
Leica Microsystems: Dental Microscopes — dental surgical microscopy provides high magnification, illumination, and visualization for endodontics, restorative dentistry, implantology, prosthodontics, and oral surgery.
Align Technology: iTero Scanners — iTero intraoral scanners create high-resolution 3D scans and reduce the need for traditional impressions.
AAE: Cone-Beam Computed Tomography — CBCT provides 3D views of teeth and surrounding structures and can enhance diagnosis/evaluation/treatment in selected cases.
