Can Cavities Heal?
This question needs to be more specific!
Can cavities heal themselves? The answer is NO.
Can the cavity heal with the help of some medication? The answer is NO.
Can the enamel regenerate the way other tissues of the body do? Sadly NO.
The only way to treat cavities is to mechanically removed the infected portion of the tooth and restore it using dental fillings or caps.
The reason being the cavity causing bacteria cannot be killed using medication!
Making the enamel (white portion of the tooth) all the more precious.
Brushing Twice a Day and Bi Annual Visits to Vasupujya Dental will keep the Bacteria at Bay.
