Teeth Whitening at Mint Dental Loft
Teeth whitening at Mint Dental Loft in Altadena, CA uses professional-strength products and customized techniques to lighten discoloration and enhance your smile safely. Whether you want a quick boost for an upcoming event or a more dramatic transformation, we tailor your whitening plan to your teeth and lifestyle.
What Is Professional Teeth Whitening?
Professional teeth whitening uses dentist-supervised gels and systems to break up stains on the enamel and dentin layers of your teeth. Everyday habits—like coffee, tea, red wine, or tobacco—can leave your smile looking dull or yellow over time. Whitening helps reverse these changes by gently lifting color from inside the tooth, not just the surface.
Because treatment is planned and monitored by our team, we can adjust the strength and timing to reduce sensitivity while still giving you noticeable, reliable results.
- In-office whitening A fast, focused appointment in our office for visibly brighter teeth in a single visit.
- Custom take-home trays Personalized trays and professional gel you use at home on your own schedule.
- Targeted stain removal Designed to address both surface and deeper discoloration more effectively than store brands.
- Guided, predictable results Dentist oversight helps you avoid uneven whitening and overuse.
How the Teeth Whitening Process Works
Your whitening journey starts with an exam to ensure your teeth and gums are healthy and to identify any existing restorations that will not change color, such as crowns or fillings. We then discuss your goals and recommend either in-office treatment, take-home trays, or a combination of both.
During in-office whitening, we protect your gums, apply the whitening gel, and monitor your progress in short, controlled steps. For take-home whitening, we create custom trays, provide detailed instructions, and schedule follow-ups to track your results and comfort.
- Smile shade assessment We record your starting shade and desired outcome to guide treatment.
- Personalized whitening plan Strength, timing, and method are chosen based on your needs and sensitivity.
- Ongoing support We check in on your progress and adjust as needed for comfort and results.

Am I a Candidate for Teeth Whitening?
You may be a good candidate for teeth whitening if you have healthy teeth and gums and want to improve discoloration from food, drinks, aging, or smoking. Whitening does not change the color of existing crowns, veneers, or fillings, so we may discuss updating restorations after whitening to match your new shade if needed.

Teeth Whitening FAQs
- Is professional teeth whitening safe?
- Yes. Professional whitening uses hydrogen peroxide or carbamide peroxide to break down stain molecules within the enamel, and it does not soften or weaken tooth structure at supervised concentrations. Mint Dental Loft examines for decay, leaking fillings, and gum recession first, since whitening gel reaching exposed dentin or an untreated cavity is what causes problems.
- Will teeth whitening make my teeth sensitive?
- Temporary sensitivity is the most common side effect and typically lasts 24 to 48 hours after treatment. It occurs because peroxide passes through enamel into the dentinal tubules, and it resolves without lasting harm. Mint Dental Loft applies desensitizing agents and can lower gel concentration or shorten wear time for patients prone to it.
- How long do teeth whitening results last?
- In-office whitening typically holds for one to three years, and take-home tray whitening for a similar period with occasional touch-ups. Coffee, tea, red wine, and tobacco shorten that considerably. Mint Dental Loft provides custom trays so results can be refreshed at home for a night or two rather than repeating full treatment.
- Will whitening work on all types of stains?
- No. Yellow and brown surface staining from food, drink, and tobacco responds well. Grey discoloration, tetracycline staining, and a single dark tooth following trauma or a root canal respond poorly or not at all. Mint Dental Loft assesses the type of discoloration first and recommends internal bleaching, bonding, or veneers where whitening will not work.
- Can I whiten my teeth if I have crowns or fillings?
- You can whiten the natural teeth, but crowns, veneers, bonding, and fillings do not lighten, so existing restorations stay their original shade and can end up looking darker by comparison. Mint Dental Loft whitens first, waits two weeks for the shade to stabilize, then replaces any visible restoration to match the new color.
- Is professional whitening better than over-the-counter products?
- Yes, for both strength and fit. In-office gel is considerably more concentrated than anything sold over the counter, and custom trays hold gel against the teeth while keeping it off the gums, which strips and generic trays cannot do. Mint Dental Loft also screens for decay and recession beforehand, which over-the-counter use does not.
- How quickly will I see results?
- In-office whitening produces a visible change in a single 60 to 90 minute appointment, commonly lightening teeth by three to eight shades. Take-home trays work more gradually over ten to fourteen nights. Mint Dental Loft records the starting shade so the change can be measured rather than estimated.
- How do I keep my smile white after treatment?
- Limit coffee, tea, red wine, and dark sodas, or drink them through a straw, and rinse with water afterward. Avoid smoking, which stains faster than any food or drink. Mint Dental Loft supplies custom trays so you can refresh the shade for a night or two every few months rather than repeating full treatment.
- How do I get started with teeth whitening in Altadena, CA?
- Call Mint Dental Loft in Altadena at (626) 639-8618 or request an appointment online. The consultation records your current shade, examines for decay, recession, and existing restorations, and confirms whether in-office or take-home whitening suits the type of staining present.
