What are the liabilities of a dentist for defective tooth filling and crowning?

I brought my daughter to a dentist for tooth filling. The dentist only put white filling in the molar tooth which has two walls broken and recommended to have it protected with a crown. After a week we returned to the dentist for the crowning. The gums bleed when the dentist took impression of the tooth for the size of the crown. Thereafter, there was a dark coloured thing surrounding the white filling which looks like a tooth decay or a blood stain. The dentist said not to be bothered about it. Likewise, despite of the complained pain after the filling, the dentist still fixed the crown yesterday and the pain continued. The denstist said just give my daughter a paracetamol ibuprofen tablet. After four hours the crown was detached. The dentist can not be contacted because she is reportedly out of town. What shall we do? Please help. Thank you very much.

If you want to keep seeing this dentist for this particular tooth, go to your local pharmacy and get from the dental section a product for temporary filling / recementation. You should place the crown back in with this material. Before you do this, play with the crown and figure out the best position (fit) on the tooth. When you are ready tp put in the crown, dry the area first, place the material in the crown, then place the crown in the mouth and have her remain open (close her teeth, but have her show you her teeth the whole time----also tilt her head back) unitl it dries. This will extend the amount of time the crown will stay in. This is also the reason the crown came of or "detached" beacuse she was bleeding and the area was not dry when the crown was put in. As soon as you can schedule her an appointment with the dentist. She has to guarantee her work. If you take her somewhere else, the original dentist is not responsible for the cost.
Reply:go back to the dentist and get this fixed.
Reply:I understand u r anxiety and frustration. Medical fraternity enjoys over whelming protection from patient vindicating them. So, to get relief for pain and further rectification, pl select different doctor from Appollo dental hospital or any other known dr. U hav not mentioned which city r u in? So. that , i can suggest someone if it is Bangalore or Chennai.
