My family absolutely loves Tyngsboro Cosmetic Dentristy! We been going there for over 10 years, before our twins were even born and they now go there too. Their attention to detail, professionalism and friendly atmosphere makes you feel welcome and appreciated and not just another patient. Thank you Dr. Y!

My dentist for 30 years. I don't have enough adjectives to describe how well I've been treated there. Professional, courteous and very responsive to my needs. My calls are always returned and after procedures has he has called to check on me, even on weekends. His staff is a direct reflection of himself. Upfront with costs and payment options and always willing to help me. Couldn't say enough about them.

I've been going to Dr. Yankowskas' office for many years. Everyone is kind and caring. My teeth are healthy, so I've never had an issue requiring serious dentistry, just replacement of some old fillings. I recommend Dr. Y for keeping your smile healthy and bright.
