A word from our founder Dr Pippa Nicholls
“I am on a mission to change up the toothpaste market. For years, people have been putting up with toothpaste that uses cheap ingredients from by-products of the fertilizer industry, alongside other ingredients that are known irritants and carcinogens, like SLS and titanium dioxide.
That is why I developed Dimples – a toothpaste designed to be a toothpaste. No cheap by-products or fillers. Only good quality, effective, and safe ingredients.
Dimples utilises hydroxyapatite, which is the mineral that your teeth are made from naturally, meaning they are being remineralised and protected by what is meant to be there. We also use xylitol which helps balance and maintain a healthy microbiome, which is very important in overall health.
We don’t use any SLS, titanium dioxide, parabens or artificial flavours, and our toothpaste is vegan and cruelty-free. Additionally, we use sugar cane tubes and cardboard cartons – both renewable and recyclable.
My goal was to create a brand that had a positive effect on your teeth, your health and the planet.“
Pippa’s Bio
Pippa grew up in Yorkshire, and attended school in Harrogate. She has been interested in natural health from a young age, being brought up by a naturopathic nutritionist as a mother. The chocolate in the house was always raw and organic, and spirulina made it into most smoothies (along with lots of veg)! Pippa’s interest continued through school, and at 17 years old, she completed a large project reviewing scientific data on the safety of amalgam fillings.
Determined to find a more holistic path to help people with their oral health, which is ultimately linked to the health of the whole body, Pippa then went on to study Dentistry at Cardiff University, and graduated in 2017 with a Bachelor’s in Dental Surgery. During her studies, she completed a meta-analysis titled “Review of Nutritive and Non-Nutritive Sweeteners and their Effects on Oral and General Health”, which covered the health effects of natural and artificial sweeteners.
Since University, Pippa has developed her practice and works in general dentistry, helping her patients take control of their oral health. It was the inspiration that Pippa gained from her patients that led her to found Dimples Oral Care in 2023, when she realised there were no toothpastes on the market that she could whole-heartedly recommend to her patients.
