1 /5 Komal: Read ALL the YELP reviews first please. I HIGHLY recommend reading all the reviews for Thank You Dental on YELP before going in for anything. If thats not enough to convince you to avoid this place then look up "welcome dentistry 1721 W Katella reviews" and read the yelp reviews. Thank You Dental was originally named "Welcome Dentistry", they have TONS of bad reviews trying to be covered up with 5 star reviews. A quick google search will show you everything you need to know about this place. I didnt read them and I regret it. I went in for a "little cavity", "small filling"... which are direct quotes from the doctor and the assistant. There was alot of pain afterwards even after 2 weeks for something so small so I went back and they say I now need a root canal. A root canal is a very intensive process, its not the same as a small cavity. This office always makes me keep coming back for more and more things, it honestly feels like a cash grab, which seems to align with alot of other peoples experience with this place.
