Some signs of periodontitis may be gum pockets; loose teeth; gaps forming between teeth; bad breath; receding gums, that is, gums that are pulling away from the teeth, giving the teeth a longer appearance; and bleeding gums.
Nendeks võivad olla igemetaskud, loksuvad hambad, vahed hammaste vahel, halb hingeõhk, igemepiiri taandumine ning veritsevad igemed.
