Ashlee Venegas
I had a veneer crack in two on one of my front teeth. They got me in immediately and got me fixed up with a nice looking temporary. My new veneer will be ready in 3 weeks. They reassured me that their work comes with a 100% satisfaction guarantee. I'm happy about that because I'm not an easy one to please. After all, it's my front tooth they're fixing
