I am sorry to hear about your incident. It is unfortunate. However, if your tooth was knocked out and re-implanted by your dentist, chances are very good that it is non-vital (dead). The only way for you to keep this tooth in your mouth without an infection is by getting root canal treatment, and a final restoration (probably a filling to close the root canal access).
If you have any doubts, I'd recommend going to an Endodontist-the root canal specialist, for a second opinion.
Nevertheless, it sound like your dentist is doing the right thing.
It does not sound like anything is wrong. As long as you have no pain, fetid (stinky) odor, and other symptoms, you are healing well. If you are concerned, the right thing is always to call your dentist. He/She MUST know if there is anything wrong and should be more than happy to reassure you that everything is right.
You should have a two week post-op visit to make sure that the healing is progressing properly.
Although I would love to give you a diagnosis over the internet, without a proper examination and X-rays it will all be pure speculation.
You MUST take your son to the dentist! Finances are NOT a factor. You can find out free and reduced fee clinics in your area. Dental schools and hospitals also offer reduced fee, and sliding scale payments.
The cost of regret is immeasurable and dental problems ONLY become worse.
Please take your son to the dentist for proper diagnosis and treatment.
First of all, any question is a good question. You are not the only one to ask it.
The number one thing to do is to go to the dentist for a proper diagnosis. There is very limited remineralization (re-compositions) of the enamel can happen ONLY under certain circumstances with limited decay. It is ONLY a decision that a professional can make.
There are products such as Colgate Phos-flur, which can help, however, again, you need a diagnosis by your dentist.
You do not want to use the product on a cavity that is already beyond the repair point and needs professional intervention.
Please go to your dentist. It is the best that you should do.
Allow me to assure you that everything is perfectly normal. It is not uncommon for children to have there adult teeth start growing in prior to the exfoliation of the deciduous, baby teeth. AS a matter of fact the only thing that needs to be done right now is careful observation by a dentist.
You are doing the right thing. Any insurance company pays well for preventive care especially for children. Please go see a pediatric dentist near you.
www.aapd.org will have a proper link to locating a Pediatric dentist in your area.
It is unfortunate that you went in for new work, and came out with a major problem. However this does happen. The question is: why? You have to trust your dentist to diagnose the problem and determine what needs to be done. Typically a bite adjustment by itself should not generate horrible pain. Most times people are just in discomfort.
If your Doctor does not know the reason and the pain persist, I, whole hardly, recommend you to see a specialist for a second opinion. The specialist in this field is called a Prosthodontist and if you go to www.gotoapro.org you can locate one near you.
I am so sorry to hear about your problems, but there is help. Here is the website for the Wisconsin Dept of Health Services. There are many options there and you should explore them. Many clinics and schools offer free or reduced dental care. You just have to do a bit of leg work and, unfortunately put up with long wait time in he clinics. However it is far better than doing nothing.
I am glad that you did not loose it. Go to the pharmacy and get some denture adhesive paste (Fixodent or Polygrip). Put very little into the crown and place it over the remaining tooth structure. That should hold it until you can see the dentist.
If it gets loose, re-cement it.
The temporary cement that they have in the store is typically too thick and you might not be able to cement the crown properly.
