Palmer Notation Charting Symbols: A UK Dentist's Cheat Sheet

Palmer notation is the UK-standard tooth numbering system, taught in every UK dental school and used in NHS records, BPE scoring, and most UK dental practice management software. This cheat sheet covers the four quadrants, the eight tooth positions per quadrant, the symbols used on a dental chart, and how to read them at a glance.

What is Palmer notation?

Palmer notation divides the mouth into four quadrants based on the patient's perspective:

• Upper Right (UR) - top right from the patient's point of view
• Upper Left (UL) - top left
• Lower Left (LL) - bottom left
• Lower Right (LR) - bottom right

Within each quadrant, teeth are numbered 1 to 8 from the midline outwards. So the central incisor is 1, the lateral incisor is 2, the canine is 3, the first premolar is 4, the second premolar is 5, the first molar is 6, the second molar is 7, and the wisdom tooth is 8.

A tooth is therefore identified by its quadrant + position - for example UR6 is the upper-right first molar; LL8 is the lower-left wisdom tooth.

| Quadrant | Tooth | Number | |---|---|---| | Upper right | Central incisor | UR1 | | Upper right | Lateral incisor | UR2 | | Upper right | Canine | UR3 | | Upper right | First premolar | UR4 | | Upper right | Second premolar | UR5 | | Upper right | First molar | UR6 | | Upper right | Second molar | UR7 | | Upper right | Third molar (wisdom) | UR8 | | Upper left | Central incisor | UL1 | | Upper left | ... | UL2-UL8 | | Lower left | Central incisor | LL1 | | Lower left | ... | LL2-LL8 | | Lower right | Central incisor | LR1 | | Lower right | ... | LR2-LR8 |

Primary (deciduous) teeth - the 20-tooth chart

Children have 20 primary teeth. Palmer notation uses letters A-E instead of numbers, again from the midline outwards:

• A - central incisor
• B - lateral incisor
• C - canine
• D - first molar
• E - second molar

So ULA is the upper-left primary central incisor; LRE is the lower-right primary second molar.

Common dental charting symbols

These are the symbols you'll see on a UK dental chart, on top of Palmer-notated tooth identifiers:

| Symbol | Meaning | |---|---| | O | Occlusal restoration | | M | Mesial restoration | | D | Distal restoration | | B | Buccal restoration | | L | Lingual / Palatal restoration | | MOD | Mesio-occluso-distal | | RCT | Root canal treatment | | Cr | Crown | | Br | Bridge | | X or / | Tooth missing / extracted | | R | Restoration (generic) | | Comp | Composite | | Am | Amalgam | | GIC | Glass ionomer cement | | IMP | Implant | | RR | Retained root | | UE | Unerupted | | PE | Partially erupted | | + | Tooth present (charted) |

How a charted tooth looks in a UK clinical note

UR6 MOD Comp. Composite restoration on the mesial, occlusal, and distal surfaces of the upper-right first molar.

LL8 RR. Retained root of the lower-left wisdom tooth.

UL1 RCT + Cr. Root-canal-treated upper-left central incisor with a crown.

This is exactly the format that AI dental notes platforms like Dentistry Dashboard generate from your spoken consultation - the AI is trained on Palmer notation specifically, so dictating "upper right six MOD composite" produces the correctly-notated entry without you having to type a thing.

Palmer vs FDI vs Universal

Palmer is the UK standard. The two other systems you'll come across:

• FDI two-digit notation - international (and used by most software). UR6 in Palmer = 16 in FDI; LL8 = 38.
• Universal numbering - American. Numbers all 32 teeth 1-32 starting from the upper right wisdom tooth.

Dentistry Dashboard AI Notes lets you switch between Palmer, FDI, and Universal in universal settings - the AI applies your preferred notation to every note.

Why notation matters for medico-legal records

The General Dental Council requires "contemporaneous, complete, and accurate patient records." Charting errors - the wrong tooth notated, ambiguous symbols, missing surfaces - are a recurring source of dental complaints and disputes. Two practical tips:

1. Spell out the quadrant every time. "UR" + tooth number is harder to misread than just 6.
2. Note the surface(s) for any restoration. MOD comp is unambiguous; "composite" alone is not.

When to use AI to chart

Manually charting from a hygiene visit takes 5-10 minutes. With voice-driven AI charting (like Dentistry Dashboard's Voice Perio Charting) it takes under 2 minutes. The AI applies Palmer notation correctly, captures BPE scores, and writes the note in the format your PMS expects.
