Helping my Autistic son with emergency dental TM

Hi, my name is Latisha and this is my 19 year old son Kadrin. He has Autism. We recently found out that he has a gum disease and has to have 20 of his teeth pulled. This is very heartbreaking for my family and I. I'm a single parent and have been raising Kadrin on my own all of his life. He has dental insurance through my job and he also has dental insurance through denti-cal, but neither will cover him getting implants. The dentist informed me that without the removal procedure, it can cause him to be in a lot of pain and it could be life-threatening. As you all know dental procedures can be very expensive. The dentist told me that the procedure and implants will cost anywhere from $15,000 to 50,000. Which my family and I cannot afford. We have never done anything like this but we are desperate. Whatever you can donate is very much appreciated. Thank you in advance.
