Hello,
it is very difficult to treat uncooperative child esp when it comes to dental treatment, we advice to start visiting your dentist with your child as early as when the kid is 1 yr of age, so that the kid gets used to clinic environment at the same time it keeps a check on oral and dental health of the kid. the option you have now is to visit a pedodontist and ask about nitrous oxide sedation for performing the treatment procedure
Next Steps
