Chief Dental Officer, Peg Paste

With more than ten years in clinical practice and a deep specialisation in preventive dentistry, Dr Cate Gerber joined Peg Paste to help shape the future of oral care in Australia — bringing clinical insight and evidence-based expertise to every formulation.

“The principle behind micro-hydroxyapatite is biomimicry — supporting the tooth with a material structurally similar to what it is already made of. I find that an elegant idea, and one with a growing evidence base.”

— Dr Cate Gerber, BDS, Chief Dental Officer

Science. In practice. Every day.

ON BIOMIMICRY

“Hydroxyapatite is the primary mineral component of tooth enamel. The principle behind using it in toothpaste is biomimicry — supporting the tooth with a material structurally similar to what it is already made of.”

— Dr Cate Gerber, BDS

ON REMINERALISATION

“Enamel cannot regrow in the way bone heals, but the mineral surface can be supported and rebuilt at a microscopic level through remineralisation. Micro-hydroxyapatite is one of the agents the research community is paying close attention to in this space.”

— Dr Cate Gerber, BDS

ON FLUORIDE-FREE CHOICE

“For patients who, for personal reasons, are looking for a fluoride-free option, I want them using something formulated on a credible active ingredient rather than guessing in the supermarket aisle.”

— Dr Cate Gerber, BDS

ON CLEAN FORMULATION

“I read a lot of toothpaste labels, and I appreciate a formulation that has been thought through carefully — both in what it includes and what it leaves out. Peg Paste is one I happily recommend on that basis.”

— Dr Cate Gerber, BDS

ON SENSITIVITY

“Dentine hypersensitivity is something a significant proportion of my patients deal with. The proposed mechanism of micro-hydroxyapatite — occlusion of exposed dentinal tubules — is one of several approaches we have, and the early evidence is promising.”

— Dr Cate Gerber, BDS

ON FAMILIES

“Parents often ask me what toothpaste is suitable for their family, particularly when they are trying to avoid certain ingredients. Peg Paste is a formulation I discuss with them as one of the options available.”

— Dr Cate Gerber, BDS
