Switch to a private, single-owner practice immediately. Chains hire newly graduated associate dentists on commission, which is why you see a different face every 6 months and leave with a list of 'recommended' procedures.
Check out Welch Dental Group or McKaskle Family Dentistry in Katy, or Crabtree Dental. All three are independent practices where you'll see the exact same dentist every visit, and they have longstanding reputations in the community for never upselling or pushing corporate quotas.
