Three weeks ago I had bone graft on "tooth" 11. I had this tooth removed 4 months ago due to fracture and an autologous bone graft (from my chin) was placed for a future implant.

The bone graft got a little exposed on the palate site, I think this is because of exagerated vertical augmentation and poor blood irrigation.

This little piece of exposed bone is dead and I'm afraid of getting an infection, specially because I know ostemyelitis is a severe problem.

I'm washing my mouth and brushin the exposed bone with Chlorhexidine after each meal. I took antibiotics for the first 19 days (amoxicillin 14 and levofloxacin 5). Now im on day 23

How dangerous is my situation? What cares should I take?

Thanks
