Hi there .. If the cavity is infected, then it cannot be recovered naturally...first you get all the cavities filled by a nearby dentist...then follow some steps to control them.. Take care..!!

Hello..Brush with fluoride toothpaste after eating or drinking. Brush your teeth at least twice a day and ideally after every meal, using fluoride containing toothpaste.....Fillings, sometimes called restorations, are the main treatment option when decay has progressed beyond the earliest enamel-erosion stage. Fillings are made of various materials, such as tooth-colored composite resins, porcelain or combinations of several materials...Consult nearest dentist they will do the needful

Hi..you cannot remove a cavity by any method once they catch your tooth. Dentist's drill is the only way to remove it. However there are prevention measures, use fluoridated toothpaste. Brush twice daily. Undergo cavity fillings if required. Protect new teeth by pit and fissure sealants by Dentist. Regards
