What does dental mean?
Dental is an adjective relating to the teeth or to the branch of medicine that cares for them. It appears constantly in everyday life — dental check-ups, dental insurance, dental hygiene — and is equally at home in clinical settings, where it describes procedures, instruments, and anatomy involving the teeth. A second, more specialized sense belongs to phonetics: a dental consonant is one produced with the tongue touching or near the upper teeth, such as the 'th' sounds of English. The word derives from the Latin dens (stem dent-), meaning tooth, which also underlies dentist, dentistry, indent, and trident. Connotations are practical and health-related rather than emotional; it is a neutral, formal-to-everyday term with no figurative uses. Its usefulness lies in its precision: whenever something concerns teeth specifically rather than the mouth generally, dental is the exact word.

(Of a speech sound) articulated with the tongue against or near the upper teeth.
"The English fricative in 'thin' is dental."
Used almost exclusively in linguistics.
The Latin word dens, meaning tooth, hides inside words as different as trident — literally 'three teeth' — and the dental consonants your tongue makes against your teeth right now.

Etymology of dental
Dental comes from the Latin dens (stem dent-), meaning 'tooth', combined with the adjective-forming suffix -al. English adopted the word via French or directly from Latin in the early modern period, and it remains closely tied to its cognates dentist and dentistry, which were coined later from the same root. The same Latin stem appears in unrelated-seeming English words such as indent and trident.
