Well, not exactly. I can guarantee that you don’t say “adolescen–t--s”, an impossible cluster in any variety of English. Instead, you end the word – the consonant after the “n” – with a “ts” sound – a dental which doesn’t make a sound by itself, followed by a sounded sibilant with the fact that you started it with your toungue in a dental position audibly noticeable.
In other words, EXACTLY how you pronounce “adolescence”. There, the dental position occurs because that’s where our tongue already is when we make the “n” sound.
Don’t be fooled by how we WRITE these (or any) words! You must try to ignore writing when analyzing spoken language (as all of humanity in effect did for the first approx. 145,000 years of language, and as maybe a fifth of humanity still does today. Plus all children aged about two to five.)
