If you have a cavity and brush your teeth regularly 3+ times a day, is it possible for the cavity to dissapear on its own?

:(: I have not heard of resolving a cavity this way, but brushing and flossing after you eat could prevent future cavities.

Unfortunately, no: A cavity is a bacteria infected hole in a tooth. Brushing and flossing will not remove the decay and fill the cavity, a dentist must do that for you. And then regular brushing, flossing, and chec-ups will reduce the cance of new cavities.

Not quite BUT...: If it is a very early small accessible cavity that is detected by a precise device (diagnodent) and the dentist treats the area with ozone, ; you consistently apply a re-mineralization paste (mi paste) ; have meticulous home care (accurate brushing and flossing) ; watch your diet (few sweets, etc). Then you could "heal" the cavity without drilling and filling! I have successfully done this!

Prevention: Is permanently damaged area in the hard surface of your tooth: enamel, dentin or root surface. The cavity is caused by bacteria, poor oral hygiene and frequent consumptions of sweets. If cavity is not treated, it get larger and affect deeper layers of your teeth and you might need a root canal or tooth extraction. Rec.: see your dentist for x-ray and treatment. Prevention, prevention, prevention.

Old Wive's Tale: Brushing the teeth does not prevent tooth decay--it's an old myth we were told as kids to get us to brush our teeth. Brushing and flossing help to prevent gum disease. Tooth decay is caused primarily by sugar and acid in the diet, acid from the gut, or a combination of factors including genetic predisposition.It must be prevented. Once present, it must be treated. Prevention can't treat infection.
