Claiming dental expenses??

I recently had three fillings removed and replaced with new ones and was told I could claim tax relief on this. When I got the Med 2 form however, it clearly states fillings are not covered by dental tax relief. The dental nurse had mentioned something about the med2 form being misleading as it appears you can't claim relief when you can. So now I'm confused - can I claim dental tax relief for these fillings or not? They cost €300 and some kind of refund would be great...

According to the Revenue document [broken link removed], you can't claim for fillings - a full list of what you can claim for is at the end of the document.
