Why Do Teeth Become Sensitive?
That sharp jolt of pain from an ice-cold drink or a spoonful of hot soup usually means the enamel layer protecting your teeth has worn thin, exposing the microscopic tubules underneath that lead straight to the nerve. Enamel erosion can come from acidic food and drinks, aggressive brushing, teeth grinding, or simply age. Once those tubules are open, hot, cold, sweet, and even air can trigger pain.
Most toothpastes for sensitivity work by numbing the nerve. BIOREPAIR takes a different approach — it tries to physically rebuild the enamel and dentin surface itself.
What Makes BIOREPAIR Different: microRepair Technology
BIOREPAIR's active ingredient is microRepair® — zinc-substituted hydroxyapatite particles with a mineral structure very close to natural tooth enamel. Because the particles are biomimetic (chemically similar to your own enamel), they can bind directly to the tooth surface, filling in micro-cracks and closing exposed dentin tubules rather than just coating over them.
In independent clinical research, microRepair has been shown to:
- Close exposed dentin tubules within about 30 seconds of contact, cutting off the pathway that causes sensitivity pain
- Deposit a meaningfully thicker mineral layer on the tooth surface compared to standard toothpaste, helping remineralize early enamel damage
- Continue binding and protecting with regular use, rather than washing away after rinsing
Fluoride-Free — By Design, Not By Accident
BIOREPAIR contains no fluoride, which is why it is formulated to be safe even for children under 6 without adult supervision at the sink. It also leaves out several ingredients found in many mainstream toothpastes:
- No titanium dioxide
- No Sodium Lauryl Sulphate (SLS) — gentler on irritated gums and sensitive mouths
- No parabens
- No silica abrasives — won't scrub away already-thinning enamel
This makes it a good option for patients who specifically want a gentler, fluoride-free formula — but it isn't automatically a replacement for fluoride toothpaste for every patient, especially those who are cavity-prone. Dr Kent can advise whether BIOREPAIR should replace your regular toothpaste or be used alongside it.
The BIOREPAIR Range
BIOREPAIR isn't a single product — the range is built around different concerns:
Fast Sensitive Repair — for immediate relief of sensitivity, can be massaged directly onto the affected tooth
Total Protective Repair — everyday enamel repair and cavity protection
Gum Protection — hyaluronic acid formula for delicate, receding, or irritated gums
Pro White — gentle whitening without abrasive scrubbing
Kids & Junior — fluoride-free formulas safe for little ones
Is BIOREPAIR Right for You?
BIOREPAIR is worth considering if you experience:
- Sharp pain from hot, cold, sweet, or cold air
- Visible enamel thinning or erosion
- Gum recession exposing tooth roots
- A preference for a fluoride-free toothpaste for yourself or your child
It is not a substitute for treating the underlying cause of sensitivity — grinding, cavities, or advanced gum recession still need to be assessed and treated by a dentist. Think of it as one tool that works well alongside proper dental care, not instead of it.
