OZEN is formulated specifically for sensitive teeth and gums, using our patented AeroGraft™ technology, only available from OZEN. Unlike conventional toothpastes, OZEN works by forming a protective layer over exposed dentine tubules, providing relief from the very first use while continuing to build long-term protection over time.

AeroGraft™ is our patented delivery system, derived from aerogels, that ensures active sensitivity-protective ingredients reach and bond effectively to exposed dentine - the porous tissue beneath the enamel that causes pain when stimulated. This targeted approach means faster, longer-lasting relief compared to standard sensitivity formulas.

Yes, OZEN contains fluoride at dentist-recommended levels. Fluoride strengthens tooth enamel and helps prevent cavities and decay, making OZEN a complete daily toothpaste - not just a sensitivity treatment.

No. OZEN uses a low-RDA (Relative Dentine Abrasivity) formula, meaning it cleans teeth effectively without unnecessary wear to enamel or exposed dentine surfaces. This is especially important for those with sensitivity caused by enamel erosion.

Absolutely, we recommend it. OZEN is designed to be your daily toothpaste. Consistent twice-daily use is actually what allows the active ingredients to build up the protective layer that delivers sustained sensitivity relief.

OZEN gently polishes surface stains without aggressive whitening agents that can worsen sensitivity. If you are looking for a brighter smile, our formula supports gradual natural whitening - however it is not marketed as a whitening toothpaste and prioritises sensitivity care first.

OZEN comes in two clean, gentle mint flavours - light enough not to irritate sensitive tissues, but fresh enough to leave your mouth feeling clean and confident.

OZEN is a smooth paste formulation. We found this delivers more consistent coverage across all tooth surfaces and supports better adhesion of the AeroGraft™ active layer.

OZEN is the result of 10 years of clinical formulation and testing. The AeroGraft™ delivery technology was developed in partnership with dental researchers and engineers at University College London to ensure it meets the standards expected of a clinically credible sensitivity solution.

No. OZEN has a mild, clean mint flavour. We deliberately avoided strong artificial flavours, which can be irritating for people with oral sensitivity, receding gums, or post-treatment tenderness.

Sensitivity typically occurs when dentine - the layer beneath your enamel - becomes exposed. This can happen through enamel erosion, gum recession, brushing too hard, or as a result of dental procedures. Exposed dentine contains tiny tubules that connect to the nerve, and when triggered by hot, cold, sweet, or acidic stimuli, they transmit pain signals.

In our clinical trial 89% users report noticeable relief on the first day of brushing. For sustained, long-term protection, we recommend using OZEN twice daily for at least four weeks, which allows the active ingredients to build up a durable protective layer.

Yes. Post-whitening sensitivity is one of the most common complaints in oral care. OZEN's formula is well-suited for use before, during, and after whitening treatments to soothe and protect the tooth surface.

Yes. OZEN is specifically designed to be gentle on exposed root surfaces caused by gum recession, which is a leading cause of sensitivity. Its low-abrasion formula protects rather than aggravates vulnerable areas.

OZEN is an excellent choice following fillings, crowns, scaling, root planing, or other dental procedures that often leave teeth temporarily more sensitive. However, always follow your dentist's specific post-treatment advice first.

Cold sensitivity is one of the primary complaints our formula addresses. The AeroGraft™ layer physically blocks the dentine tubule response to cold stimuli, reducing that sharp, shooting discomfort.

Yes. Heat sensitivity operates through the same dentine tubule mechanism as cold sensitivity, and OZEN's protective layer addresses both.

Persistent or severe tooth pain can sometimes indicate a cavity, cracked tooth, or other dental issue that requires professional assessment. OZEN helps manage everyday sensitivity, but if your pain is intense, localised, or does not improve after four weeks of consistent use, we recommend consulting your dentist.

OZEN is formulated for adults. For children experiencing dental sensitivity, we recommend consulting a paediatric dentist for age-appropriate products and advice.

OZEN contains fluoride and low-abrasion ingredients that help maintain enamel integrity and resist further erosion from acidic foods and drinks. It supports enamel health as part of a consistent oral care routine.

OZEN's active ingredients include fluoride for cavity protection and AeroGraft™ - both well-tested, clinically supported compounds.

Yes. OZEN is SLS-free. Sodium lauryl sulfate is a foaming agent found in many toothpastes that can trigger ulcers and irritate sensitive oral tissue. We removed it to make OZEN kinder to your mouth.

No. OZEN contains no parabens. We are committed to a clean, clinically effective formulation without unnecessary preservatives that raise consumer concern.

Yes, OZEN is fully vegan. We do not use any animal-derived ingredients and have not used animal testing at any stage of product development.

Yes. OZEN is certified cruelty-free. We do not conduct or commission animal testing, and we do not sell in markets that require it.

No. OZEN's formula is free from artificial colours. The paste's appearance comes entirely from its naturally whitish base ingredients.

Yes. OZEN does not contain any gluten-derived ingredients and is safe for those with coeliac disease or gluten sensitivity.

No. Triclosan is an antimicrobial agent that has been removed from many oral care products due to safety concerns. OZEN does not contain triclosan.

OZEN uses a minimal, consumer-safe preservation system to maintain formula integrity. Full ingredient transparency is available on-pack and on our website product page.

OZEN contains fluoride at standard dentist-recommended levels, which is considered safe during pregnancy. However, as with any oral care product, we recommend checking with your midwife or medical professional if you have specific concerns.

OZEN does not contain nut-derived ingredients. However, if you have a severe allergy, always review the full ingredient list on-pack or contact our support team before use.

OZEN is currently working towards formal halal and kosher certifications. In the meantime, the formulation contains no pork- or alcohol-derived ingredients. Please reach out to our team for more information.

Glycerin can be derived from plant-based sources (typically vegetable oils) or synthesised. OZEN uses a vegetable-derived glycerin. It is not an artificial additive - it occurs naturally as a byproduct of soap and biodiesel production from plant fats.

Without a humectant like glycerin, toothpaste would dry out and become grainy or unusable within weeks. It also gives the formula its smooth consistency, which matters more for sensitive teeth than it might seem - an abrasive or uncomfortable texture can aggravate sensitive gum tissue and make people less likely to brush consistently.

Apply a pea-sized amount to a soft-bristled toothbrush and brush for two minutes, twice daily - morning and night. After brushing spit out the excess and avoid rinsing to allow the AeroGraft™ to stay on your tooth surface to begin working. For enhanced sensitivity relief, you can apply OZEN oral gel directly to sensitive areas and leave it for one minute before rinsing.

Yes. OZEN works well with both manual and electric toothbrushes. If using an electric brush, ensure you are using the sensitive or low-pressure mode to avoid unnecessary force on delicate enamel and gum tissue.

For maximum fluoride benefit, we recommend spitting out excess paste but not rinsing with water immediately after brushing. This allows the active ingredients to remain in contact with your teeth for longer.

A pea-sized amount is sufficient for adults. Using more does not increase effectiveness and can accelerate product consumption.

Yes, but we recommend leaving a gap of at least 30 minutes between brushing with OZEN and using mouthwash. Using mouthwash immediately after brushing can wash away the fluoride and AeroGraft™.

Yes. For targeted relief, apply a small amount of OZEN oral gel directly to the sensitive tooth surface using a clean fingertip and leave for 60 seconds before spitting. This is particularly helpful for acute sensitivity flare-ups.

OZEN contains fluoride and is not intended to be swallowed. Adults should spit and rinse as normal. Keep out of reach of children under 6, and ensure young users are supervised when brushing.

Once opened, OZEN should be used within 12 months for optimal freshness and efficacy. The PAO (period after opening) symbol on the packaging will confirm this.

Yes. OZEN is safe to use with fixed braces, retainers, and other orthodontic appliances. The fluoride content is beneficial for protecting enamel around brackets, where acid attack risk is higher.

Both. Consistent twice-daily use is the most effective routine. Night-time brushing is especially important as saliva production drops during sleep, reducing the mouth's natural ability to neutralise acids and remineralise enamel.

Yes. OZEN's outer carton is made from FSC-certified recycled card and is fully kerbside recyclable. The tube is made from sugarcane-derived bio-resin, which is compatible with plastic recycling streams in most UK councils - check your local guidelines.

OZEN uses a bio-based tube made from sugarcane HDPE, which has a significantly lower carbon footprint than conventional petroleum-based plastic while maintaining the same functionality and shelf stability.

Yes. The flip-top cap is made from the same HDPE material as the tube and can be recycled alongside it. We recommend rinsing before recycling.

Not entirely - the tube requires a bio-based polymer to maintain product integrity and shelf life. However, we have significantly reduced virgin plastic use and are actively working towards a fully compostable or refillable packaging solution.

We are currently developing a refill and return scheme for OZEN. Sign up to our newsletter or follow us on social to be the first to hear when this launches.

Sustainability is core to OZEN's values. We are committed to reducing our carbon footprint across formulation, packaging, and supply chain. Our current focus is on bio-based packaging, carbon-neutral fulfilment partnerships, and eliminating unnecessary secondary packaging.

Yes. All print on OZEN packaging uses water-based, solvent-free inks that do not interfere with recyclability.

Squeeze out as much product as possible, then rinse the tube and cap. Flatten the tube and place it in your plastic recycling. The outer carton goes in paper or card recycling.

OZEN currently works with carbon-neutral delivery partners and is building towards a full product lifecycle carbon assessment. We will publish our emissions transparency report on our website once complete.

We have reduced the outer carton to the minimum size needed for product protection in transit and retail display. Future product iterations will explore whether unboxed formats are viable at scale.
