You may want to think about getting a dental discount plan for your current need. Discount plans are not insurance but they do not have any waiting periods and normally start the next business day. For what you will be wanting done, you are going to get a least 20% saving off the cost of wisdom teeth estractions. That is still a large saving on a 10.00 plan.
You can also get the Insurance like Delta Dental that has the waiting periods. That way while you have the waiting periods the dental discount plan will at least save you some money well worth the cost of the plan. I have included a link for your review.
