A Spanish-formulated 16% carbamide peroxide system used for gentle, gradual whitening at home. Includes custom trays and a boost kit with a photopolymerising gingival protector for sensitive enamel.
In-chair advanced whitening
SDI's professional 38% hydrogen peroxide gel, used in-chair for fast, dramatic results in a single session. Refrigerated, light-sensitive, and applied under strict clinical control.
Specialist oral care support
A gentle yet highly effective oral care gel trusted by healthcare professionals. X Gel makes oral hygiene easier for patients who struggle with traditional brushing, opening mouths, protecting gums, and enabling thorough cleaning even in the most challenging cases.
“The change and the difference has been phenomenal. This little product does wonders. She puts little drops in the mouth and the next thing these mouths are nicely wide open like little birds. She was actually able to do the clean on those teeth, which is amazing.”

Remineralising & sensitivity protection
A professional-grade cream containing Recaldent™ (CPP-ACP) that replenishes lost minerals in tooth enamel. Recommended post-whitening to reduce sensitivity, strengthen enamel, and protect against decay. Available directly through Christine as part of your aftercare plan.

Your Whitening Journey
Every treatment is measured against the Vita 3D-Master shade guide. From consultation to aftercare, here is how Christine delivers your brighter smile.
Christine assesses your enamel, shade, and suitability at her Randburg practice or in the comfort of your home. Your starting shade is recorded using the Vita 3D-Master guide so progress is measured objectively.
Impressions are taken for custom-fitted trays. For in-chair clients, gum protection and prep takes approximately 15 minutes. If mobile, Christine brings everything needed.
Professional-grade gel is applied in controlled increments over approximately 90 minutes. Most clients see 6 to 10 shades of improvement in a single session. Christine monitors throughout; comfort and safety are never compromised.
You receive a detailed aftercare guide and your shade record showing documented improvement. Follow-up support is always available. Christine is just a WhatsApp message away.

Results vary by individual. The final shade achieved depends on the starting condition of your teeth, the depth and type of staining present, and your natural enamel characteristics. Some clients may require multiple sessions to reach their desired outcome. For best results, a professional cleaning is recommended prior to whitening, available as a separate service.
Reviews
Christine and her team changed my life. When you can’t smile, you can’t be happy, because the smile signal isn’t sent to your brain. After my transformation, I can smile again and really feel happy. I can highly recommend Smile High. Christine and her team are simply the best!
Colleen Anderson, Randburg
Christine is a charming, engaging, intelligent bright star. About 20 years ago I met this sparkling young lady and she taught me all about plaque, a word I didn’t even know back then. She is a marvellous, kind, and gentle Master of her art. God bless your ongoing journey.
Maureen, Long-term patient, 20+ years
Christine and her team make me relaxed every time I sit in the dentist chair. They are kind, caring, considerate, and helpful. Professional in what they do. I leave with a big smile on my face.
Caroline de Castro, Smile High Whitening patient
Warm, friendly and professional are just a few words I would use to describe Christine and the experience I had when getting my teeth whitened. It boosted my self-esteem and I was so proud to show off my new smile. Thank you so much for everything you and your team did for me. I will recommend you to everyone. Keep up the great work and for spreading beautiful smiles wherever you go.
Michelle Hansen, Smile High Whitening patient
I’ve been to a few other dental professionals who tried whitening my teeth, but it would always fade after a couple of months. I’m so pleased I went to Christine. She not only whitened my teeth but also made me a custom bleaching tray. I had staining from antibiotics, and with the trays we finally got to the shade I wanted. I’m so happy with my smile.
Karen Laing, Smile High Whitening patient
I highly recommend Christine for her professional teeth whitening service. She explained the entire process clearly and made the treatment simple, comfortable, and effective. I am extremely happy with the results, the difference is remarkable and has given me a real boost in confidence. Now I just want to smile!
Neville Higgs, Smile High Whitening patient
FAQ
Most clients experience little to no discomfort. Some sensitivity during or after treatment is normal and temporary. Christine uses desensitising protocols and adjusts the gel concentration to suit your enamel. For clients with existing sensitivity, the take-home kit is often the gentler path.
Most clients see 6–10 shades of improvement on the Vita shade guide. Results depend on your starting shade, enamel type, and the cause of staining. Christine measures your shade before and after every treatment so you can see the difference objectively. The consultation includes a realistic assessment based on your teeth specifically.
With good oral care and occasional maintenance, results typically last 12–24 months. Christine provides a full aftercare guide, and many clients use a take-home kit for top-ups every 6–12 months. Diet and habits (coffee, red wine, smoking) affect longevity. Christine covers all of this in your aftercare session.
Whitening gel only works on natural tooth enamel. Crowns, veneers, and composite fillings do not change colour. Christine assesses any existing restorations during your consultation and will advise on the most even, natural-looking outcome. In some cases, restorations can be replaced to match your newly whitened teeth.
Yes. Christine offers a full mobile service across Johannesburg and Gauteng. She brings all professional equipment to your home, office, or care facility. The treatment is the same quality you would receive at her Randburg practice. A call-out fee applies depending on your location. Simply mention you would like a mobile appointment when you WhatsApp or call.
Yes, when performed by a qualified professional. Christine is an HPCSA-registered oral hygienist with 30+ years of experience. She uses only clinically approved, professional-grade products at controlled concentrations. Over-the-counter and salon whitening often use unregulated products that can damage enamel. Christine's treatments protect your teeth and gums throughout.
Pharmacy strips use low-concentration gel in a one-size-fits-all tray. They cannot match the strength, custom fit, or clinical oversight of professional treatment. Christine's gels are up to 10× stronger, applied with custom-fitted trays and gum protection. The result is faster, more even, and monitored by a registered professional. Not a box instruction leaflet.
