Textbooks on phonetics say /t/ and /d/ before a dental consonant (for instance /t, d/ in “eighth” or “width”) are generally realized as dental rather than alveolar consonants.
But how about /t, d/ before an “interdental” consonant?
I believe many native speakers of English pronounce /θ/ and /đ/ as interdental consonants (tip of the tongue is placed between the upper and lower front teeth) but not dental consonants (tip of the tongue is placed behind the upper front teeth), so do their /t/ and /d/ before /θ, đ/ turn into interdental consonants?
I feel making an interdental stop is much harder than making a dental stop…
Or even people who have interdental /θ/ use dental /θ/ in /tθ/ cluster so that they can pronounce both /t/ and /θ/ as dental consonants?
