Hi.
Welcome to HEALTHCARE MAGIC..
I have gone through your query and can understand your concern..
As per your complain it seems that your daughter is suffering from Nursing Bottle caries leading to decay in upper and lower front teeth making them black and broken and she does not have pain due to
necrosis of the
nerve fibres present inside the tooth due to infection..
In this case Pulpectomy procedure or
Root Canal Treatment is appropriate and by this teeth are not removed but they are saved by cleaning the root canals of the teeth and making them infection free followed by capping them if needed..
As the
permanent teeth erupt by the age of about 6-7 years therefore it is a better option to get the teeth retained so that the milk teeth fall naturally and the permanent teeth will erupt in proper alignment..
There is no other permanent treatment in this condition and Root canal treatment is the best possible option..
As it is done under local anaesthesia and post treatment pain relievers are advised, therefore you need not to worry of pain..
Consult a Pedodontist and get treatment done which can be done even at this age of 4 years also..
Hope this information helps..
Thanks and regards.
