Seven-year-old Becca Graham had her teeth extracted by her father, Callum, who owns and works at the Queen's Drive Dental Practice, in the South Side.
The practice, next to Queen's Park, has been on the go since 1907 and Mr Graham took over a year ago as the previous owner prepared to retire.
Mr Graham and wife Heather, who also works in the surgery, decided to freeze and store their daughter's milk teeth so the youngster could take advantage of future medical advances in stem cell research.
Becca had her two wobbly front teeth removed.
She said the extraction was "a little bit sore" but she was more concerned about what the tooth fairy would bring.
Becca said: "I wrote a letter to her to explain and she sent me back £5."
Mr Graham, 42, said teeth were an "incredible source" of stem cells and researchers were studying how they could be used to treat a number of diseases and conditions, including diabetes, spinal cord injuries, stroke and liver problems.
He said: "Becca was brilliant. We explained the relevance of it, why we were going to take her tooth and she was a brilliant patient.
"It's always nerve-wracking treating your family or friends. You feel a great deal of empathy with them, as you do with all your patients, but more so with people you know."
Stem cells from bone marrow and umbilical cord blood have been used for decades to treat leukemia and other blood-related diseases.
The dental pulp from Becca's milk teeth was collected to be frozen and stored for 30 years or more until needed.
Mr Graham said he got the idea after seeing a leaflet at the surgery for Precious Cells, a cell banking company.
The father-of-three, from East Kilbride, said: "There has been a lot of research lately about stem cells and how to deliver them and use them to cure diseases, leukemia, diabetes and cancers.
"We had been looking for a way to store stem cells when Becca was born. We had heard all about it and thought it was a good idea."
The technique is one of a host of new ones the practice will be offering to its patients, which number about 6000.
This will include Naturalskn, a non surgical facelift much like the celebrity-used Vampire Facelift, which injects blood back into the patient's face.
It will also offer a service called CEREC, which can make a new false tooth to be fitted during a single visit and within an hour.
SURGERY PUTS DENTAL 'ANTIQUES' ON SHOW
AS well as offering patients some ground-breaking services, Mr Graham is also bringing a touch of the old back to the surgery.
During a recent clear-out, he unearthed a host of antique dental equipment in the surgery's loft and cupboards.
Mr Graham said: "We found old dental diplomas from the early 1900s for the owners and whoever worked here at the time.
"We found an old pedal-driven drill, almost like an old sewing machine.
"I had never seen one before and it is hard to believe that only 40 years ago they were still using them.
"There was an old box that, I imagine, would have been used by a travelling dentist, almost like a doctor's bag. It has all the things like needles and syringes you would potentially need to fix someone's tooth.
"They are probably only of great interest to dentists and they will not be worth money, but it highlights the history of the place that patients have been receiving treatment here for more than 100 years.
The surgery was established in 1907 by the Heavenor family. Its last owner, Glen Heavenor, retired in July this year.
Now, Mr Graham intends to put the historic equipment on show to patients.
They will be on view at an open day tomorrow, which will also give patients a chance to look into some new techniques he is integrating in the practice. It is at 118 Queen's Drive.
