Whitening trays are custom (or semi‑custom) trays that hold a bleaching gel against your teeth. The gel (often hydrogen peroxide or carbamide peroxide) penetrates the tooth enamel and breaks down stains, lightening the colour of your teeth.

The wear‑time depends on the strength of the gel and your sensitivity. Light‑strength gels may need 30 minutes to a few hours, higher strength gels often are worn overnight. Follow your provider’s instructions.

Mild sensitivity is common during whitening and usually temporary. You can take a day off between treatments, use desensitising toothpaste, and avoid very hot or cold foods. If sensitivity continues, stop and consult your dentist.

For customers who want to avoid sensitivity altogether, our peroxide-free gels are a great option, they deliver whitening results with zero sensitivity.

Only if your whitening gel instructions specifically say it’s safe. Some gels are designed for overnight use, while others are not.

Most whitening gels are worn for 30 minutes to 2 hours, depending on the strength. Always follow the instructions provided with your gel to avoid sensitivity.

Our whitening trays cover your teeth up to and including your second back teeth. They do not extend to wisdom teeth. This ensures proper gel contact on visible teeth while maintaining comfort and preventing excess material waste.

Usually, you’ll notice changes after a few days. Full results often appear after 1–2 weeks of consistent use. If your teeth are more deeply stained, it may take longer.

Yes, when used properly under guidance. Some temporary sensitivity or mild gum irritation can occur, especially early on. Using too much gel, leaving it on too long, or using ill‑fitting trays increases risk. Proper fit and following directions minimise issues.

Sensitivity is common. If it happens, reduce wear time or take breaks between sessions. Use toothpaste designed for sensitive teeth. Your dentist can advise alternate gel strengths or lower frequency.

Whitening gels do not whiten crowns, veneers, or fillings like they do natural teeth. However, whitening methods can help lift surface stains from these restorations, restoring them closer to their original, natural shade.

Yes, whitening gels are typically peroxide-based (such as carbamide peroxide or hydrogen peroxide). You should only use gels specifically made for dental whitening trays. Household peroxide or unapproved gels are unsafe and should never be used.

Yes, you can reuse your trays as long as they remain clean and well-fitting. After each use, rinse with cool water, gently brush off any residue, and let them air dry.

Store them in a protective case.

If your trays become warped, cracked, or loose-fitting, you’ll need a replacement to ensure proper results and safety.

With proper care, whitening trays can last for months. Most people use them for multiple treatment cycles, but if they become cracked, warped, or loose, it’s time to replace them for the best results.

The small indents (or “reservoirs”) are placed over each tooth to hold a small pocket of whitening gel. This helps the gel stay in contact with the tooth surface, spreads it evenly, and improves whitening results while preventing overflow onto your gums.
