If your tooth is decayed to an extent where a filling is not possible, but the crown treatment seems too much, then your dentist might suggest the inlays and onlays procedure. These are used in place of fillings to restore badly decayed teeth. Inlays help restore the cusp’s biting surface, whereas Onlays restore more extensive damage, which is extended beyond two cusps. If you have worn teeth, do not delay to contact your dentist. Living with decayed teeth can worsen your entire oral health and affect your neighboring teeth and jawbones.
