Congratulations on joining the expansion (TPA)
I have worn mine (an RPE) for 22 days now. At first (the first week), I HATED the thing. After about 10 days, things improved A LOT, kind of over the span of 2-3 days. Less saliva, teeth less sensitive to chewing with the device and I stopped losing weight, and most importantly
MY SPEECH CAME BACK
I was horrified the first couple of days about the speech part, but what happens is that as you expand along, there's more room for the toungue and announciation returns. Now I can even say THIRTY, FORTY, REACH
I am locking my RPE next week Thursday and will post with progress pics. I am quite please with the effect so far and have seen a lot of expansion and movement as a result of the RPE and headgear that I wear at night. I am not wearing brackets yet though.
Oh and as a last note, I would be careful of playing with TPA/RPE using the tongue as you can easily get sores.
Use salt water rinses as KK recommends - awesome.
I strongly recommend getting a Waterpick to clean out the TPA. You'd be amazed what you will find up there after meals!
