These sounds are made by touching tip of tongue to alveolar ridge. The tongue on the ridge stops egressive airflow momentarily. /t/ and /d/ from too and dew are linguaalveolar stop consonants. Allophonic variants of these sounds are ladder, butter, rider, etc. these are produced with lingualveolar flap.
