Does amoxicillin get rid of acute necrotizing gingivitis and what causes this infection?

Antibiotics Help: Acute necrotizing ulcerative gingivitis is an aggressive infection of the gums around the teeth that is caused by poor oral hygiene. Periodontal infections are an invasion of multiple bacteria and other microbes that cause a truly uncomfortable inflammation of the tissue. Antibiotics help but must be accompanied by a thorough cleaning (debridement) of the gums and teeth. Peroxide rinses help too.

Need teeth cleaned: No, amoxicillin only kills bacteria in your periodontal tissues. You need to see your dentist to have a complete oral examination and evaluation. Then the proper type of cleaning can be done to remove all the contaminants around your teeth to help your gums start to heal. If you don't get this treated, you could develop periodontal disease and could lose some teeth.

See a dentist ASAP: If acute necrotising ulcerative gingivitis is left untreated, it can cause more severe oral and health complications. in case of ANUG, amoxicillin and more aggressive methods (gum surgery) may need to be necessary.
