Failed implant. Is it worth trying again?

[barona]

I am a 59 years old female; a non-smoker, with no health issues and not on any medication.
I had an upper L-H side molar pulled out 18 years ago.
Two years ago I had a sinus lift done and an implant placed.
The implant failed after a month.

My surgeon said we can try again, but that the implant may fail again.
(He did not say why it may fail ?)
So we tried again.
While accessing the area, he said he can't proceed, as the sinus membrane is too thin
and that possibly it was caused by graft.
He said if we go ahead my implant will fail for sure.

I was told not to blow my nose for two weeks and to take Augmentin for two weeks.
Then I will have to take antibiotics for four more weeks (= 6 weeks of antibiotics in total).
So after 6 weeks a new implant will be placed.
(In the meantime I feel like maybe I developed sinusitis?)
I am so disappointed and am not sure if it's worth it doing it again. My hopes will go up and it may happen again.
I would be thankful for your advice.

Is your surgeon a general dentist or a board certified oral surgeon or periodontist? If he/she is a general dentist, you may consider seeing a specialist.
