What actually helps oral health?
The basics still win: brushing twice a day, flossing, and regular dental checkups. On the supplement side, xylitol has the most solid evidence for reducing cavity-causing bacteria, and oral probiotics/postbiotics are a genuine, fast-growing area of research for plaque, gums and breath — though most products don't disclose their doses.
Be skeptical of anything promising to "reverse cavities," "cancel dental surgery" or replace professional care. Bleeding gums and tooth pain are reasons to see a dentist, not just to chew a tablet.
