I have a mild case of pericoronitis and DO NOT have dental insurance and so far havent been able to find a free dental service In my area. Can I use do?

Community health. See if you can locate a community health center that offers dental services. Sometimes pericoronitis responds well to careful oral hygiene but not always. Contact HHS as suggested or your state health department. There are quite a few programs to help but they can be tricky to find.
Assistance program. Pericoronitis will not go away on its own, so it's important to see a dentist. Assistance programs vary from state to state. Contact U.S. Department of Health and Human Services to find out about care in your area. Another possible source of lower-cost dental care is a dental school clinic (low cost). Take care.
Other options. Only a fraction of people have dental insurance through their employer. And there's always a deductible, too, as well as a co-pay, so it's never free. You can seek reduced fee care at a dental school or hospital residency program. Healthcare financing is always an alternative. One way or another, you need to budget healthcare costs into your expenses. All the best...
Unfortunately. Unfortunately, small problems often become larger ones, whether it is medical, dental, auto, etc. It is always more cost effective and smarter to find a way to address these issues sooner rather than later. I'm sure you can find some way to work this out, both now and in the future. One cannot expect to get free care or services. Look for a job with dental coverage. http://www.freedentalcare.us/
Pericoronotis. keep the area as clean as possible. Rinse with warm salt water. Use ibuprophen for pain, 600 mg every 6 hours. See a dentist ASAP as this can get worse. You can see a dentist even without dental insurance. If you have a dental school or training hospital they may have low cost treatment programs.
Check dental society. Check in phone book or online for the state dental association or local dental society and research if there is a dental office that may help.
Seek dental school. Pericoronitis treatment generally involves antibiotic treatment to lower the inflammation followed by removal of the affected tooth. However in some instances pericoronitis is a stage during an eruption of a tooth which might not have to be extracted once eruption is completed. Your financial situation might be resolved if you find a local or nearby dental school with an oral surgery clinic.
Keep area clean. Pericornitis is swelling of the gums up onto the chewing surface of the tooth. It is caused by bacteria and most often occurs on the back side of the last lower tooth. This gum swelling hurts and is even worse if the opposing tooth bites down on these gums. The key is to keep this area clean until you can see a dentist-floss this area, clean with water pik, and do warm salt water rinses.
Insurance. Most people lido not have Dental Insurance, and if they do it often only covers a portion of the expense of treatment (copays, deductibles, etc.). Dental health care has to be budgeted for, just like internet access, smart-phone purchase costs, etc. Talk to Dentist about payment plans. Contact Social Services. Ask local Dental Society for sources. Good luck.
WaterPik. flush it regularly with an oral irrigator. Use a diluted non-alcohol mouthwash solution.
Dental Society. Your local dental society may have options for free or low cost care. Hopefully your wisdom teeth can be evaluated and treated by an oral surgeon.
Obamacare. If possible, see if your Obamacare benefits include dental. Schools and residency programs many times offer reduced fees in addition.
Brush. You can try to vigorously brush the area, but unfortunately if you actually have pericoronitis you will need professional intervention and maybe antibiotics.
Check further. Is there a dental school nearby? Maybe a hospital near you has dental department that provides charity care. Your question may have been cut off, so I hope my short answer was of some help to you.
Antibacterial rinse. You really should see a dentist but until you can you should use some antibacterial mouth rinse and try to clean around the tooth with a toothpick.
Soak. Hot water as hot as you stand in your mouth with a pinch of salt....large glass....take a mouth full;; & soak (not rinse) the area bothering you. When it cools off, spit it out & take another mouth full. Finish the glass & do this every 2 hours. Every hour if it makes it feel better. Should take 10 min each session. Continue this until you get relief.
Brush, brush, brush. Pericoronitis, by definition, is a condition of which the tissue surrounding the clinical crown is inflamed. Thus our objectives are to eliminate inflammation by establishing drainage of the tissue, i.e. brushing the area meticulously. Do not be afraid that the area might bleed. Continuous brushing over several days will stop the bleeding and the tissue will be much more healthier.
Rinse well. Thre are a few things you can try and do. Rinse your teeth really well with lukewarm salt water or you can try getting a rubber tip stimulator and see if you can get the irritant out (sometimes periconrinits is from food getting caught under the tissue) good luck.
Salt water. rinse with warm salt water and take advil (ibuprofen). see your dentist as soon as you can.
Oral hygiene. Having a case of pericornitis can be painful and limiting but normally can be resolved or controlled. It is often associated with wisdom teeth. The gums get inflamed from food and plague getting under the tissues. It can be traumatized by biting down on the sore gingiva. Normal care is to keep area clean with gentle brushing and flossing, rinse with hot salt water or mouthwash, and soft diet. .
Palliative treatment. Pericornitis is an inflammation of the flap/pocket of gum around a partially erupted tooth. After it swells it can radiate pain to the ear & make it hard to open your mouth. Aggressive rinsing with salt water, Hydrogen peroxide or Listerine can help. Ultimately the material under the gums must be removed and the area irrigated to improve the situation, maybe an antibiotic, ultimately extraction.
