It's big quistion for us with th mony we spend versus the benefit we get from the treatment. I took three injections of prp/acell costing me nearly 6000 dollers . But the relief i got is zero. In fact i have a worse sleep schedule over past few months.

So the thought is why people go for rigorous procedures like getting implants or CFDs or getting prosthesis done. If merely these injections can generate the volume inside our cavities , everybody will go for it. but the facts are coming that the injections are sheer waste of money.
There is no guarantee for any specific individual that there will be a benefit. But it is just inaccurate to say that the injections are a waste of money. In your case, it could be that if you received more than 3 injections you would see benefit but maybe you wouldn't. That is for you to decide if it is worth trying or not. Still, there are plenty of people that are getting benefits. Some have great improvement and some less.  For many, even if it is not a cure, getting a better quality of life is worth it.
