Dr. Carpenter,

So many times in business and life in general, we are pummeled with the negative. I just wanted to drop a quick positive note to let you know how pleased I am with yourself and the entire staff at M Street Dental. My entire family have been patients with you for many years. I don’t believe anyone will tell you they enjoy going to the dentist and I will confess I am no exception. M Street Dental however has always maintained a genuinely positive and friendly atmosphere where I feel as though I am among friends. This includes your entire staff. On Thursday, January 17th, I went into your clinic expecting to have a what was left of a tooth that had broken off extracted. To my pleasant surprise you have put me on a treatment plan to basically “resurrect” this tooth. Keep up the great work & kudos to you all.

When I asked for an evaluation of my mouth, I thought I would probably lose all my remaining teeth, and start over. Remarkably you immediately removed the remains of 2 teeth and set up time the next day to make impressions. Your assistant made very good impressions, and made time the next day for your lab people to add to and repair my existing partial plates. A great job by all of you! The fit is amazing, and they work almost as well as normal teeth. They have needed no adjusting and I can eat green salad again, and apples! And the teeth that show in a smile look very natural. Thank all of you for a good job, well done. It is much appreciated! All done in 4 days!! Unbelievable! Thank you very much.
