You may want to look into getting a dental discount plan, since you have immediate needs. Dental Insurance at this point may not cover you to see an Oral Surgeon or they may have a long term waiting period before you can be covered. I taken a monet to give you some information about what a discount dental plan is as noted below.
This type of dental plan is not insurance. The managing organizations have negotiated with local dental offices to establish a set price for a particular dental procedure and offer deep discounts (some up to 70%) off the regular ADA pricing code. This plan has several advantages over traditional dental insurance plans, namely, there are no exclusions for pre-existing conditions. This allows a patient to receive immediate coverage for work without meeting any waiting period requirements.
