Which type of consonant sounds are produced using the lips and teeth?

The correct answer highlights that dental consonant sounds are produced using the lips and teeth, specifically by placing the tongue against the upper teeth. Dental sounds include phonemes like /θ/ (as in 'think') and /ð/ (as in 'this').

In context, alveolar sounds are made by placing the tongue against the alveolar ridge (just behind the upper front teeth), while velar sounds involve the back of the tongue contacting the soft palate at the back of the mouth. Palatal sounds are articulated with the body of the tongue against the hard palate, further back in the mouth. Each of these categories utilizes different parts of the mouth to produce their unique consonant sounds, distinctly separating them from dental sounds.
