Dental negligence, bad doctor caused lasting damage to gum, can I claim compensation?

[Henry]

I was victim for a dental negligence and would like to claim compensation for damage to my gum.

I need to do a claim for this doctor who left my mouth worse after dental surgery and left me in agony.

MyDentist is the name of institution, I went there because i had a pain in my tooth, i was to do programation which I didn't really understand.
all the staff were very arrogant, the doctor was very angry and his behaviour was bad, he made me do anaesthesia in my gum and removed the bad tooth but did a poor job, snapped the tooth and bean pulling out roots with so much power and he generated a wound so bad it filled with blood in my mounth, i was cried sying ok in the chair and he don t stop it.

I was hope this wound be done but every day is more pain and everyday i need to eat but i can not.

I can not eat, i can not sleep, i missed work for 4 days, i have a big pain in all my mouth and my face is still anesthetised.

Tell me what can i do, because this doctor need to stop working I have pictures and documents and my mouth who is destroyed.

How much compensation could I claim for damages from medical negligence?

Thank you
