The area of necrosis can be very tender and sensitive. It is not recommended to wear you denture when you have an area like this. I recommend you leave your denture out until it heals and is comfortable. It will heal on its own, but may take several weeks. There are a few things you can do to help with the discomfort in the meantime, and also aid in helping it heal. First, I recommend that you rinse with warm salt water twice a day. This will keep the area clean, and prevent infection
. If the area is an open sore, you may also want to be on antibiotics to prevent infection. Ask your dentist
about what is best to prescribe, probably penicillin. Second, you can get treatments at your dental office of eugenol and benzocaine. This elixir is very good at easing pain
and aiding in recovery. Normally it is placed on a small piece of gauze and placed in the are of necrosis or dry socket. You may need this to be done every other day until it feels better. Something else you can do at home is place wet tea bags on the area to help in healing. Tea has tannic acid in it, which aids in healing. This has proven useful with many patients. Finally, if ibuprofen isn't enough to take away your pain, you may consider asking your dentist for something stronger, like vicodin. You should not drive while on this, however.
After a few weeks, you should be healed, and then you can wear your denture all day. Until then, try not to wear your denture all the time, as this may irritate the area of necrosis and slow down healing.
