Totally wrong diagnosis! Luckily I contacted my dentist in Italy. I was feeling pain in the lower left part and he Q&M dentist found the cause in the top left part suggesting extraction or root canal. He made panoramic xray and checked all my tooth one by one and didn’t see an obvious cavity in the bottom left. Please check the attached photo! My Italian dentist suggested me to go to a dentist in Jkt. I went there and he found the obvious reason of my problem and he fixed it (root canal in the bottom left tooth: approx. Rp. 6.000.000). I hope the Q&M managers will contact me and open an investigation.
Recommendation: My suggestion is: stay far from this clinic.
