Gum disease is a common condition in which the gums become swollen, sore, or infected. It is caused by bacteria that accumulate on gums and teeth. Diseased gums may bleed when people brush their teeth and may cause bad breath. If gum disease is not treated, teeth can become loose and eventually fall out. This can affect a person’s ability to chew and speak. It can also make people feel self‐conscious about their appearance. Dental‐care professionals can clean teeth and gums to remove excess bacteria from the mouth. They use special instruments – typically, an ultrasound scraper followed by specialised hand‐held instruments – to scrape bacteria from the teeth and stop these from affecting the gums.

Antibiotics (medicines that kill bacteria) taken by mouth (orally) can be used alongside professional cleaning, to remove bacteria from the area between the teeth and gums. However, there are potential risks associated with antibiotics, such as allergic reactions and antibiotic resistance (changes in bacteria after exposure to antibiotics, that allow the bacteria to survive future antibiotic treatment).
