6-8 age groops kids also taking from bottal.? It's not a good thing. U have to consult ur pidiatrisian and pidodontist. Rampant caries occurred in somanny kids. These kid need dental tretments.

Sir we appreciate ur concern but remember one thing, caries do happen due to sugar ( carbohydrate) + bacteria & plaque, All history you are telling suggest us that probably ur are not able to clean ur kids mouth with brush & mouthwash also clean anterior teeth with wet cotton swab....... N dis was missing sir So next permanent teeth will come at the age of 7-8 years & we do need to save teeth & have treatment for current milk teeth as they can not sustain far with such kind of damage do visit dentist nearby &have happy smiling..

Caries is a result of genitical +food habbit +maintainence, among all the kids he maybe genetically phone, anyway since he is already having ramped caries better to treat him to the possible extent and take preventive measures like, avoiding night time bottle feading,cleaning the teeth twice morning and night and regular visits to pedodontist,
