About Final TH words
90% of children produce voiceless TH by 6;11 (Crowe & McLeod, 2020), later than any other consonant, so a final TH error in a five-year-old is usually within normal limits. In word-final position the substitution is again /f/ — bath becomes baf, tooth becomes toof.
Final TH is frequently the last item on an articulation plan, and not only because of the age norm: the sound is quiet, brief, and easy to omit entirely at the end of a word without the listener noticing the difference between a substitution and a deletion.
Practising Final TH
Because the sound is weak, exaggerated length helps — hold the TH well past its natural duration so the child can both see and hear it. Single-syllable entries such as bath and math give the cleanest listening conditions.

- How many words have /th/ in the final position?
- Our dictionary lists 27 final /th/ words suitable for speech therapy practice.

- Are all final TH words voiceless?
- Nearly all common ones are — bath, math, tooth, mouth. A few, such as smooth and breathe, carry the voiced TH, so it is worth checking the word rather than assuming from position.
- At what age should final TH be correct?
- 90% of US children produce the voiceless TH by 6;11 (Crowe & McLeod, 2020). Substituting /f/ before that age is common and generally does not warrant treatment on its own.
