سلام
این دو تا تاپیک میتونه کمکت کنه و مطلب جالبی که تو یک سایت دیدم 
There are two different sounds, but a lot of people always pronounce them the same. Both are made by putting your tongue between your teeth so that the tip of your tongue is touching your teeth.
TH – voiced dental fricative /ð/ (with vibration)
This TH sounds like “this” and is a soft sound. To pronounce this TH, place the tip of your tongue between your top and bottom teeth and vibrate your vocal cords – it’s quite fun!
Words that have the /ð/ sound are:
than – then – this – weather – smooth – other
TH – voiceless dental fricative /θ/ ( no vibration)
Words with this TH are, for example, “thing” and “thought”. It is a much stronger sound. To pronounce this TH, do the same: place the tip of your tongue between your teeth but just blow air through your mouth without vibrating your vocal cords.
Words that have the /θ/ sound are:
thank – think – therapy – moth – path – youth
