The word order in a tooth's name
In English-language records the sequence is fixed, and it is learned as a formula:
arch → side → dentition → position → tooth type
- upper right permanent first molar
- lower left primary second molar
First upper right molar is understandable but is not how a chart is written. The same logic governs general adjective order: a small white composite filling, with size before colour and colour before material.
For orientation: upper and lower, anterior and posterior, left and right. Depth is deep, shallow or superficial; extent is localized or generalized.
-ed and -ing forms: state against process
This distinction carries the meaning:
- -ed — a state, the result of something already done: decayed, cracked, chipped, broken, fractured, stained, discoloured, eroded, worn, impacted, unerupted, retained, infected, abscessed, inflamed, swollen
- -ing — a process happening now: aching, throbbing, shooting, lingering, bleeding, receding, protruding
Compare: a bleeding socket is bleeding at this moment; a swollen cheek has already swollen. Note too that swell gives swelled as a past tense but only swollen as the adjective.
Opposing pairs that describe a plan
Almost all treatment vocabulary is built on antonyms:
- vital and non-vital — living and dead pulp
- fixed and removable
- temporary and permanent
- acute and chronic
- mild, moderate, severe — three steps, not two
- erupted and unerupted
- invasive and minimally invasive
- surgical and non-surgical
- sterile, disposable, reusable
- healthy and unhealthy, painful and painless, comfortable and uncomfortable
- firm, mobile, loose — stable through to moving
Other treatment attributes: direct and indirect, elective, urgent, routine, preventive, restorative, cosmetic, resorbable, custom-made, keratinized.
One root, two forms
These families are worth learning whole, because records use both members:
| Noun | Adjective |
|---|---|
| caries | carious |
| necrosis | necrotic |
| mobility | mobile |
| inflammation | inflamed |
| sensitivity | sensitive |
| infection | infected |
| erosion | eroded |
| abscess | abscessed |
| pain | painful / painless |
Writing caries tooth for carious tooth marks a non-native writer instantly.
Adjectives in this set that behave oddly
- Mobile describes a tooth that moves; it has nothing to do with phones in this context
- Vital means the pulp is alive, not that something is important
- Elective means planned rather than urgent — it does not mean optional in the casual sense
- Acute is about onset and duration, not severity — an acute problem can be mild
- Swollen is the only adjective form; swelled is past tense only
- Keratinized has no common adjective pair — the opposite is non-keratinized, spelled out in full
