In what articulation does the tongue touch the teeth?

The correct answer is dental because this type of articulation involves the tongue making contact with the upper teeth. In dental sounds, the position of the tongue is crucial as it helps create specific phonetic sounds by utilizing the teeth as a point of contact. For example, English sounds like "th" in "think" and "that" are produced this way, where the tip of the tongue lightly touches the upper front teeth.

Other types of articulation, such as bilabial, nasal, and glide, involve different positions and contacts in the mouth. Bilabial sounds are produced using both lips, nasal sounds require the airflow to pass through the nose (with the mouth typically closed), and glide sounds involve a smooth transition between vowel sounds without the tongue contacting the teeth directly. Recognizing these distinctions helps understand how phonetic sounds are formed based on different articulatory processes.
