Coast Dental Services review: did not complete work as promised

The company provided a dental treatment plan listing work to be completed which included Elite Dentures both upper and lower and verbally stated that adjustments would be covered for six months. There was extensive bone removal and as the gums shrank the dentures did not fit. After approximately 5 weeks, I went in for adjustment and was informed that the dentures would have to be relined and there would be an additional charge of over $400.00. The inital bill was $5, 396.00 and my understanding was that that amount would cover all necessary adjustments for six months. From what I can ascertain from the web and other sources, this company has numerous complaints about their business practices.
