Common signs of gum disease include bleeding during brushing, swollen or tender gums, bad breath, gum recession, loose teeth, and spaces developing between teeth. Early gum disease may be painless, so bleeding should not be ignored.
Do not stop brushing if your gums bleed. Gentle brushing and interdental cleaning are important, but you should book a dental visit so the dentist can assess your gums, remove tartar, and explain the correct home-care routine.
