Pay attention to your dental and vision health before retirement. 

If your employer funds all or part of your dental and vision insurance, use those benefits to their fullest before you retire

"Fund a health savings account, or HSA, during your working years. You get a tax deduction for the amount you contribute, you can invest the money you save, and the earnings grow tax-deferred. When the money is used to pay for qualified medical expenses, the withdrawal is also tax-free."

"Some Medicare Advantage plans provide dental and vision coverage. What if you choose traditional Medicare? Consider purchasing private dental and vision insurance."

In his article Conner provides extensive suggestions and information if you need to buy private coverage.
