Sadly, Medicare does not cover additional services such as eyeglass care, hearing aids or routine dental care. Those basic services were not included in the Medicare list of benefits. To change that, Congress would need to change the Medicare laws to include these services.
The Exceptions are when routine dental care is part of a Medicare covered treatment. An example of this would be a procedure that needed to extract teeth in preparation for the treatment of cancer via radiation therapy. This example shows that while tooth extraction is not a covered Medicare Benefit, it can be covered as part of a Medicare covered treatment.
