杜完牙根生牙瘡,可唔可以告個牙醫?

想投訴個牙醫，你要證明到佢有專業失職，相信你需要花一段時間才能搞掂。現在你的情况，最好去見第二個牙醫，聽取他的意見，先搞掂自己的問題，再考慮追究。况且你都只是懷疑佢令到你杜完牙根生牙瘡，兩件事是否有關連，你都要找第二個牙醫，甚至乎第三個牙醫問問。我自已都好憎人做错事唔認及掩飾，但凡事都必需先搞清楚，以免得罪好人。

Good luck!

If you think this is relavant to the professional standard of the dentist, you may. However I think you have to see the specialist first and tell this to the specialist and see if there is a chance that the dentist is having a problem.
