Melissa Amos had never considered herself someone who needed to worry about her weight.
The 45-year-old mother-of-three from Hertfordshire maintained an active lifestyle, practising yoga, taking long walks with her dog and generally trying to eat a balanced diet.
But after turning 40, Melissa noticed that her weight was gradually increasing despite continuing to exercise.
She also recognised that she had developed a habit of reaching for snacks such as chocolate, cereal bars and cheese without necessarily being hungry.
The Moment the Scales Delivered a Shock
The change became impossible to ignore when Melissa stepped onto her bathroom scales and discovered that her weight had climbed from below 11st to more than 13st.
At 5ft 3in, that placed her in the obese category according to NHS guidance.
Yet Melissa says her weight was not initially the issue that concerned her most.
Instead, she had become increasingly worried about a lower front tooth that appeared to be moving forward.
That prompted her to make an appointment with her dentist in March last year — a visit that would unexpectedly influence both her smile and her eating habits.
Dentist Suggests Clear Aligners
Melissa was advised to try Invisalign, a system of removable, transparent aligners designed to gradually straighten teeth.
The treatment can cost between £1,500 and £5,500 and is widely used by adults who want an alternative to conventional metal braces.
Patients can remove the trays when eating, but they are generally encouraged to wear them for at least 22 hours each day.
For Melissa, that requirement quickly changed the way she approached food.
The Snack Barrier Made a Difference
Her dentist stressed the importance of being consistent with the treatment from the outset, something Melissa says made her much more deliberate about when she chose to eat.
Every time she wanted food, she had to remove the aligners and then put them back afterwards.
That extra step turned out to be enough to make her reconsider many of the snacks she would previously have eaten without thinking.
Melissa also began examining the emotional reasons behind her eating habits.
She realised that she sometimes turned to food as a distraction or as a way of making herself feel better, rather than because she was physically hungry.
Weight Loss Began Within Weeks
Within the first month of wearing Invisalign, Melissa had lost more than 2lb.
Over the following months, the weight continued to come off.
As she became lighter and felt more energetic, she also found herself increasingly motivated to exercise.
Walking became a particular favourite, while she later introduced weight training to build on her growing strength.
A New Focus on Nutrition
Melissa, who works as a mental wellbeing coach, also began paying closer attention to what she was eating.
After entering her diet into ChatGPT, she says she realised she was not consuming enough protein.
She subsequently increased her intake of foods including eggs, yoghurt, cottage cheese and peanut butter, which she says have helped her feel fuller and reduced her hunger.
Around 2st Lost So Far
Since beginning her Invisalign treatment, Melissa says she has lost approximately 2st.
With several months of treatment still remaining, she expects that figure could increase further.
The benefits, however, have not been limited to her weight.
Melissa says she has been impressed by the changes to her teeth, bite and jaw and describes the results as remarkable.
Dentist Says Patients Often Notice the Same Effect
Dr Daniel Sutcliffe, founder of The Bespoke Dentist in London, says Melissa’s experience is not entirely unusual among Invisalign patients.
He recalled hearing similar comments from patients for years, often joking that their dental treatment had unexpectedly caused them to lose weight.
The explanation, he suggests, is relatively straightforward: having to remove the aligners every time someone wants to eat can discourage casual snacking.
That additional effort can create a simple pause between a craving and the decision to eat, making some treats seem less appealing.
A Dental Treatment With an Unexpected Side Effect
For Melissa, what began as a decision to correct a protruding tooth has evolved into a broader lifestyle change.
The aligners have not only helped reshape her smile but have also encouraged her to question her eating habits, improve her nutrition and become more active.
Her experience highlights how a seemingly minor practical inconvenience — having to remove dental trays before eating — can sometimes alter everyday habits in ways patients may not initially expect.
