Dental expenses can be entered as medical expenses, and are subject to a very tough threshold to meet in order to affect your tax return. For 2017 if you were under the age of 65 only the amount of medical expenses in excess of 10% of your AGI (or if you were 65 or older 7.5% if your AGI) counted toward the itemized deduction for medical expenses.
So if you had enough other medical expenses and itemized deductions to exceed your standard deduction for your 2017 return, it *might* be worthwhile to amend your 2017 return.

A 1040X cannot be e-filed. It must be printed and mailed. It will take about 3-4 months for the IRS to process an amended return. It is a good idea to use a mailing service that will track it, like UPS or certified mail, so you will know it was received.
Wait about 3 weeks from mailing and you can check the status of your amended return:
