Canyon Country Dental Group Dr. Kim Nguyen Deceptive and Misleading Dental Practice Canyon Country California

I ordered and payed for a Custom Permanent Crown. After only 3 days it loosened and came off and I swallowed it. They then installed another crown. within a week it loosened and came off. They reinstalled it. After about 3 years of coming in every 3 months for a cleaning I began to have problems and pain with the tooth.  the only thing they did was offer to sell me more proceedures, not fix anything.  I transtered to another dental office. There I was advised that the crown they installed was a TEMPORARY and that it was deterioriting, and had been for some time.  As a direct result I sustained a very severe cavity. The cavity became very infected and spread to my jaw bone.  As a direct result of the severe infection I was forced to undergo a ROOT CANAL proceedure in an dffort to same the tooth.  When I confronted the previous dentist, Dr. Nguyen, I got excuses and stalling. Finally after some time they offered to reimburse the money I paid for the original crown.  They would not pay for the additional dental expenses I incurred or for any pain and suffering I experienced.  This is wrong, unprofessonal, based on what I have discovered, Malpractice.
