This research is still in the nascent stage and has not been applied to clinical practice. There is no way to give you an idea when this will be available in the clinics and that too in India. Stem cell research is also going on in the field of oral cancer but we cannot assure the patients who are currently suffering from it that this modality holds any special hope for them. It will be more practical to take care of your oral health by meticulous brushing and visiting your dentist regularly for a check up so that any small problem can be nipped in the bud. Regards.
