I start by taking a bite and let my jaw move, one tooth meeting crust as I chew. I press down, then shift my jaw a fraction to check the bite, feeling the tooth work with the bite instead of against it. I adjust the pressure, hold steady, and let the chewing rhythm build, the tooth becoming a steady lever in my mouth. The taste and texture set in, and I realize how this little tooth helps me get through the bite with control.
Real Context
Tooth is a noun referring to the hard, bony structure in the mouth used for biting and chewing. It also names any single member of the set of teeth, such as a front tooth or a molar. The term can describe objects that resemble a tooth in shape or function, for example the teeth of a saw or the teeth of a gear. Common phrases build on the idea of a tooth, including toothache, lose a tooth, and brush your teeth. Etymology goes back to Old English toð, related to Proto-Germanic tanþs; memory image: imagine a strong tooth biting into an apple, leaving a clean bite.
Usage Reminders
- - Remember tooth is singular; teeth is the plural.
- - Use tooth for a single tooth, not the whole set.
- - Say toothache, not tooth pain in most cases.
- - Brush your teeth, not your tooth.
- - When describing gear or saw parts, tooth means a single ridge.
- - Distinguish true teeth from metaphorical teeth in idioms.
Common Misconceptions
- Tooth only refers to human teeth, not animal teeth
- Tooth is pluralized as 'tooths' (correct plural is 'teeth')
- Tooth cannot be used in references to tool parts (they are 'teeth' of a saw/gear)
- Tooth always means the whole set of teeth in one mouth context
- You must say 'tooth pain' instead of 'toothache' in formal writing
Thinking Differences
English distinguishes single teeth from the set as teeth; this helps learners talk about one tooth vs. the whole mouth. Learners often overgeneralize with 'tooths' or mix up tooth/teeth in phrases like 'toothbrush' vs. 'brush your teeth'.

- memorize common phrases: toothache, brush your teeth, lose a tooth
