Thank you for your question and welcome to Just Answer.
Until yo can get to a dentist here is what you can try at home for the pain:
A very good way to control dental pain using over the counter medications is to switch between taking 400 milligrams of ibuprofen (e.g., 2 tablets of Advil), and 1000 milligrams of acetaminophen (e.g., 2 tablets of extra-strength Tylenol) every 3 hours. Be careful not to use these medications if you have had previous adverse reactions to either, or if you have had gastritis or peptic ulcer disease in the past, or if you have liver disease.
In addition, you can try "Toothache Drops" available at your pharmacy. This is clove oil (eugenol) which is very soothing to an exposed tooth. Place a drop or two on a cotton pellet and place on the tooth or on the hole of the tooth.
Regarding low or no cost dental treatment here are some suggestions:
1. Call your local dental society and see if there are any programs, charitable organizations or foundations operating in your area that will do your work for a discounted fee. You can find the details of your local dental society by clicking here:
2. Consider having your work done at a dental school. The fees charged are much less than those charged by a private dentist. Here is a list with links of all the dental schools in the USA, hopefully there is one near you:
Outside of these options you can always look for an understanding local dentist that will help you out by working for a reduced fee. Ask your friends, family and colleagues which dentist they like and start by asking that dentist.
In addition, here is a website that lists dental offices that offer free and discounted clinics all across the country. Search for one in your area. Read each listing carefully as restrictions apply to some of the listed outlets.
I hope this answers your question. If you would like to discuss this further or have any additional questions, please reply to my answer and I will get right back to you.
