There are cavities in my teeth. is there any way to remove these completely?

Cavities: A dentist can remove the decay and restore the teeth (up to a point). See a dentist for an evaluation and appropriate treatment.

Cavities: It's time to go see the dentist. You will have to have your cavities treated. With good oral hygene and a healthy diet that includes fluoride you can prevent future cavities. Unfortunately the ones you already have will not go away

See a dentist: Dental cavities are irreversible condition and will need to be treated by a licensed dentist. See your dentist for exam, x-rays and treatment.

Sure: The decay needs to be removed, and that can be accomplished by a dentist. Please see a local dentist for a consultation.
