Is this put on her front lower teeth, and is scraping her tougue? I had this done to me to corrrect the way i swallow due to pushing my upper teeth forward. this was done probably 38 years ago. I remember it cutting my tongue a lot, which caused cuts, hence the treatment to correct the swallow. I am unable to give you advice for coping....but i can add that i recently saw a TMJ dentist, who said that procedure is no longer used...is this an orthodontist u are dealing with? They seem to be the best ones to ask this question to......try posting on AllExperts.com and go directly to the dental section and you can find an orthodontist or dentist that will answer your question over the weekend at least. Hope this helps.
I am a certified orthodontic assistant and have been for the past 9 years. We use thumb rakes or TSR's for thumb sucking. I don't understand why he would put the TSR in there if her habit had stopped prior to placement. It is NOT going to get her ready for a palatal expander. They are two completely different appliances used for two completely different reasons. If I were you I would demand that they take it out and seek a different orthodontist with a good reputation. I am so sorry your daughter has had to deal with unnecessary procedures.
FYI, when I was a child, I had a hay rake installed to attempt to stop my lisp. I am now 40 yrs old and thank goodness my parents & ortho put it in my mouth. I stopped my lisp and now I see grown ups today with a lisp and think why didn't their parents or ortho install a hay rake? I run several companies in the L.A. area and cringe when I hear other adults w/a lisp. Yes, the first hours/day your child would be inconvenience, the same with braces on their teeth. I guess your child doesn't eat veggies either. I say horray for the hay rake.
