Dental charting is one of those things you learn in dental school, use every day, and never think about again — until someone reviews your charts in a complaint or malpractice case and asks why half the information is missing.
I charted thousands of patients over twelve years of practice. I thought my charting was fine. Then I went through a formal complaint and discovered that charting — recording what’s in the mouth — is only the beginning. What matters is what you do with those findings: how you document your clinical reasoning, your diagnosis, the options you presented, and the patient’s informed consent.
This guide covers dental charting from the ground up. If you’re a student or a newly qualified dentist, it’ll give you the complete picture. If you’re an experienced clinician, skip to the sections on the gap between charting and documentation — that’s where most dentists are vulnerable and don’t know it.

What is dental charting?
Dental charting is the systematic recording of everything present in a patient’s mouth — teeth, restorations, missing teeth, caries, periodontal status, soft tissue conditions, and any other clinical findings. It’s the visual and written map of the patient’s oral condition at a specific point in time.
A dental chart serves three purposes:
It records the starting point. At the patient’s next visit, you compare the current chart against the previous one to identify changes — new caries, failed restorations, periodontal progression, soft tissue changes.
If another dentist sees your patient — in an emergency, on referral, or because you’ve left the practice — your chart tells them exactly what’s in the mouth without needing to examine from scratch.
Your chart is evidence. In a complaint or malpractice case, the chart proves what was present at each examination. If a patient claims you missed something, your chart either confirms or denies it. If you didn’t chart it, you can’t prove you saw it.
Charting isn’t optional. Professional guidelines consider it a baseline requirement for every examination. An examination without charting is clinically incomplete and legally indefensible.
Tooth notation systems explained
There are three notation systems used globally. Which one you use depends on where you trained and where you practise. You need to know all three because you’ll encounter all three in referral letters, specialist reports, and patient records from other practices.
Palmer notation (UK standard)
Used in UK dental practice and taught in UK dental schools. Divides the mouth into four quadrants using a grid symbol (┘└┐┌). Teeth numbered 1–8 from the midline in each quadrant. So ┘6 means the upper right first molar.
Upper right | Upper left / Lower right | Lower left
FDI (Fédération Dentaire Internationale) notation
International standard. Two-digit system. First digit indicates the quadrant (1–4 for adult, 5–8 for deciduous), second digit indicates the quadrant, second digit indicates the tooth position. So 26 means the upper left first molar (quadrant 2, tooth 6).
Quadrant 1 (UR) | Quadrant 2 (UL) / Quadrant 4 (LR) | Quadrant 3 (LL)
Universal numbering (US standard)
Standard in the United States. Permanent teeth numbered 1–32 starting from the upper right third molar (#1), going across the upper arch to the upper left third molar (#16), then dropping to the lower left third molar (#17) and continuing to the lower right third molar (#32).
Whichever system you use, be consistent. Mixing notation systems within the same patient record creates confusion and, in a legal review, undermines the reliability of your documentation.
How DigitalTCO handles notation
You say “upper right six” or “tooth 26” or “number 3” — DigitalTCO understands Palmer, FDI, and Universal notation and charts it correctly in your note. You don’t need to think about which system to use. Just describe the tooth the way you naturally speak.
What to chart: the complete list
A complete dental chart at a new patient examination should record the following. This isn’t aspirational — it’s the baseline that professional guidelines consider standard.
At a recall examination, you don’t need to re-chart everything from scratch. You need to record changes against the existing chart — new findings, deterioration of existing restorations, and confirmation that previously noted conditions are stable or progressing.
The critical point: charting is recording what you found. Documentation is explaining what you did about it. Most dentists do the charting reasonably well. Where they fall short is turning those charted findings into defensible clinical notes.
Periodontal charting
Periodontal assessment is a core part of dental charting. At minimum, every adult patient should have a Basic Periodontal Examination (BPE) recorded at each examination.
Basic Periodontal Examination (BPE)
The BPE is a screening tool that divides the mouth into six sextants and assigns a code (0–4, plus *) to each based on the worst finding in that sextant. It tells you whether further, more detailed periodontal assessment is needed.
BPE codes
No pocketing >3mm, no bleeding on probing, no calculus, no defective margins.
No pocketing >3mm, no calculus, no defective margins. Bleeding on probing present.
No pocketing >3mm. Supra- or subgingival calculus and/or defective restoration margins present.
Probing depth 3.5–5.5mm (black band partially hidden). More detailed charting required in this sextant.
Probing depth >5.5mm (black band fully hidden). Full periodontal charting required. Consider specialist referral.
Furcation involvement detected. Full periodontal charting required in this sextant.
When full periodontal charting is needed
If any sextant scores 3 or above (or * for furcation involvement), more detailed periodontal charting is indicated in that sextant. Full charting includes six-point pocket depth measurements, bleeding on probing, recession, furcation involvement, mobility, and suppuration.
This data is essential for diagnosis, treatment planning, and monitoring the response to periodontal treatment. Without it, you can’t demonstrate that you identified the disease, planned appropriate treatment, or monitored the patient’s response.
Common charting failure: no BPE documented
One of the most common documentation gaps in UK dental records is the absence of a BPE at examination appointments. If a patient later develops periodontal disease and claims you never assessed their periodontal status, the absence of a documented BPE at every exam is a significant vulnerability. It takes 60 seconds to perform and 10 seconds to record. There’s no reason not to do it.
Soft tissue charting
Soft tissue screening is not optional. A comprehensive examination of the oral mucosa should be carried out at every course of treatment. This means systematically checking: lips, buccal mucosa, floor of mouth, tongue (especially the lateral borders — the highest-risk site for oral malignancy), palate, retromolar regions, and oropharynx where visible.
The most important rule in soft tissue charting: document the screening even when findings are normal.
“Soft tissue exam: NAD” takes three seconds to write. But those three seconds prove you looked. Without that note, there’s no evidence the screening happened — and if a patient is later diagnosed with oral cancer, the absence of documented screening at your appointments is a claim waiting to happen.
If you do find a lesion, document its site, size, shape, colour, texture, and whether it’s painful. Take a clinical photograph if possible — it provides a visual baseline for comparison. Any lesion that persists for more than three weeks should be referred for specialist assessment.
Extra-oral examination
The examination doesn’t start inside the mouth. You should be assessing the face, head, and neck at every examination — looking for asymmetry, swelling, discolouration, or abnormalities. Palpate the neck for lymphadenopathy. Palpate the TMJ at rest and during mandibular movements. Note clicking, grating, limitation of movement, or pain.
Again: document even when normal. “Extra-oral exam: NAD. TMJ: no clicking, full ROM” proves you assessed these areas. Without it, there’s no evidence you did.
Common charting symbols and abbreviations
Most dental software uses standardised symbols on a graphical chart. But when you’re writing clinical notes — whether by hand or by voice — you’ll use abbreviations. Here are the most common ones used in UK and US dental practice.
| Abbreviation | Meaning |
|---|---|
| MOD | Mesial-occlusal-distal (surfaces of a restoration or cavity) |
| DO / MO / OB etc | Surface combinations (distal-occlusal, mesial-occlusal, occlusal-buccal) |
| CR | Crown |
| RCT / RCF | Root canal treatment / Root canal filled |
| P+C | Post and core |
| Br | Bridge |
| V | Veneer |
| Impl | Implant |
| TTP | Tender to percussion |
| TTC | Tender to cold |
| NAD | No abnormality detected |
| BPE | Basic Periodontal Examination |
| BOP | Bleeding on probing |
| LA | Local anaesthetic |
| IAN | Inferior alveolar nerve (block) |
| XLA | Extraction under local anaesthetic |
| SRP | Scaling and root planing |
| OHI | Oral hygiene instruction |
| F/V | Fluoride varnish |
| FS | Fissure sealant |
| RD | Rubber dam |
| Temp | Temporary restoration |
| Rx | Prescription / treatment |
| Hx | History |
| Dx | Diagnosis |
| Tx | Treatment |
| O/E | On examination |
| c/o | Complaining of |
Professional guidelines recommend avoiding abbreviations unless there’s an agreed list. If you use them, be consistent across the practice. If another clinician can’t understand your abbreviation, it’s not saving time — it’s creating ambiguity that could hurt you in a review.
How DigitalTCO handles abbreviations
You can speak in abbreviations — “MOD composite UR6, RD, selective etch, Tetric Evo” — and DigitalTCO expands them into clear, unambiguous clinical notes. The generated note reads naturally and is understandable by any clinician, even if you spoke in shorthand.
Digital vs paper charting
Most UK practices are now digital — using the charting module built into their PMS (SOE/EXACT, Dentally, R4, etc). US practices are similarly digital through Dentrix, Eaglesoft, Open Dental, and others. Paper charting still exists in some practices but is increasingly rare.
Digital charting has clear advantages:

Watch out for
That last point is the one most dentists miss. Your PMS gives you a beautiful graphical chart with coloured restorations and missing teeth clearly marked. It looks comprehensive. But it’s not documentation — it’s a diagram.
The gap between charting and documentation
This is the section that matters most — and the reason I built DigitalTCO.
Charting records what’s in the mouth. Documentation records what you did about it.
Your chart might show a carious lesion on the distal surface of #30. That’s charting. But your documentation needs to answer: What were the clinical findings? What was your diagnosis? What options did you present to the patient? What risks did you discuss? What did the patient decide? What treatment did you deliver? What materials did you use? What did you tell the patient afterwards? When should they come back?
The chart answers none of those questions. It shows a red mark on tooth #30. That’s it.
This is where most dentists are vulnerable. They chart diligently — every restoration noted, every missing tooth recorded, BPE completed. Then they write a three-line clinical note that says “MOD composite #30. LA. RD. Pt tolerated well.” The chart is complete. The documentation is not.
If a complaint lands, the expert witness doesn’t review your chart and say “looks good.” They review your notes and ask: “Where is the consent documentation? Where are the treatment options? Where is the diagnosis? Where are the post-op instructions?”
How DigitalTCO bridges the gap
DigitalTCO doesn’t replace your PMS charting. Your chart lives in Dentally, SOE, Dentrix, Open Dental — wherever it lives now. DigitalTCO sits on top and handles the part your PMS is terrible at: the clinical note.
After you’ve charted the patient, you speak for 30 seconds: “#30, distal caries into dentine on the bitewing. Discussed composite versus monitoring. Patient chose composite. Risks discussed — sensitivity, possible need for RCT if closer to pulp than expected. Rubber dam, selective etch, Filtek Supreme A2. Adjusted occlusion. Told patient may be sensitive for a few days, ibuprofen if needed.”
DigitalTCO generates a structured note from that — findings, diagnosis, options presented, consent, treatment details, post-op instructions — and you paste it into the notes field in your PMS. Your chart is complete. Your documentation is complete. Both layers done in under two minutes.
Your chart shows what’s in the mouth. DigitalTCO documents what you did about it.
30 seconds of voice after each appointment. Structured, defensible clinical note. Paste into your PMS. Done.
