She's trained with the British Army and helped treat soldiers through postings in Germany, Greece, Iraq, Canada and Bolivia.
But for the past three years Dr Lorika Strickland has been at the frontline providing free dental care to some of Tasmania's most rural and remote communities.
A dentist for the Royal Flying Doctor Service, Dr Strickland has helped lead Tasmania's Mobile Dental Care program at Circular Head, Flinders Island, King Island and Smithton.
To date the program has assisted more than 3500 patients through outreach services, providing treatments for those who would otherwise go without.
However, this week marks her last with the organisation as she heads back to England to reunite with her husband, who has been working for the United Nations in Somalia.
Describing the opportunity to work with the RFDS as "life-changing", Dr Strickland said the success of the program was a credit to her team and the communities it reached.
"I have had some really great jobs where you think - this is pretty good, it can't get better than this. But I have never been so embedded in a community and become so close to patients," she said.
"It's a bit cheesy to say, but they are stories that stay with you forever. Sometimes you see a patient, but you don't follow their oral health journey.
"With our program, you really get to know people very well and quite personally. While initially all of our energy went towards just getting the project off the ground, now the momentum is there and it's changing lives."
Tooth decay remains one of the most prevalent health problems in Tasmania, with dental conditions the leading cause of potentially preventable hospitalisations.
People living in rural and remote communities are also disproportionately affected by problems associated with poor oral health.
Born in Johannesburg, South Africa, Dr Strickland started her work with the RFDS in 2017 when the Mobile Dental Care program was first putting down roots in the community.
While people in remote and rural areas continue to face barriers accessing oral health services, Dr Strickland said progress was being made.
"When we started this, we had an idea of how it could work, but we didn't know how it would be received. It was sort of a 'will this boat float' type thing," she said.
"At first we didn't have as many patients and I thought - I might be out of a job soon in the next couple of weeks. But then it just took off.
"I hardly ever talk about toothbrushes, I actually talk more about diet and lifestyle. Because it's all related.
"Depression and the treatments for depression means people have very dry mouths and often a poor diet. If they can't chew, they live off Red Bull or soft food which is also really bad for you.
"It all has a direct influence on our health, and on our mental health. So to have been able to be a part of changing that trajectory has been very worthwhile for me."
A new dental specialist has been acquired to continue Dr Strickland's work, with the RFDS also aiming to establish a third dental outreach team to help meet ongoing demand.
