Teeth grey around the gumline?
I think that only a dentist can tell you that. I can however understand about not affording the cost if you don’t have the money. You may want to try calling your local dentist and see if they can offer a free consultation. This will not get the work done but at least you will know where you stand. From there try talking to the dentist office and see if they will work out a payment plan. More and more dentist offices are willing to do so to get your business since it is hard times for them too. Not knowing your age….. You may want to get a part time job to help off set the cost for your parents. Also if you don’t have any dental insurance or can’t afford that either, think about getting a dental discount plan. This will also help in lowing your cost of services.
