I feel like I'd love to have that, but I run into the same reasoning against laser eye surgery:

My work benefits cover full dental and my contacts, but I would have to pay substantial out-of-pocket for those procedures, even if they could save the benefits plan money over time.

In practice, dental implants are more work to maintain being much more difficult to properly floss. This leads to bone absorption and receding gums.

I'm interested to know why, since I have one and haven't noticed any difficulties in flossing.

Well placed implants dont have much bone recession. On the other hand, bridges or other dental solutions where theres nothing in the bone do lead to bone loss. Poorly placed implants or crowns can lead to bone/gum loss though.

If you can get a health plan with an HSA, you can use HSA money (pre-tax) to pay for LASIK. That's what I did, and I strongly recommend it.
