WhitenUp – Frequently Asked Questions

Is Teeth whitening safe?

Yes! At WhitenUp, your safety is our top priority. Our teeth whitening solutions are designed to be both gentle and effective. While mild sensitivity or gum irritation can occur in rare cases, it’s typically short-lived and nothing to worry about.

How does WhitenUp work?

WhitenUp products use clinically proven whitening gel formulas that you can easily apply at home or while on the go. Every product comes with clear step-by-step instructions, available both in your package and on the product’s page under the “Instructions” tab.

Are WhitenUp products safe?

Absolutely. All WhitenUp products are formulated to be safe for your teeth and enamel.

Who should avoid using WhitenUp?

We recommend that individuals under 13, pregnant or nursing women, and anyone currently wearing braces avoid using our whitening products.

When will I see results?

Most users see noticeable results within 7–10 days of consistent use. For best outcomes, follow the provided usage guidelines and try to limit dark-staining foods and beverages like coffee, wine, tea, and soda.

How long do whitening results last?

Whitening results typically last 1–3 months, but this depends on your lifestyle habits. Frequent consumption of staining foods or drinks—and smoking—can shorten how long your brighter smile lasts.

What ingredients do WhitenUp products contain?

Our products contain either 35% or 44% Carbamide Peroxide, a trusted whitening agent that breaks down into hydrogen peroxide for effective stain removal.

Glycerin, Urea Peroxide, Propylene Glycol, Xylitol, Carbomer, Peppermint Oil, Triethanolamine, Aqua
All ingredients are selected for safety and efficacy.

Will WhitenUp affect dental work like crowns or veneers?

Our formula is safe for dental restorations like crowns, caps, and veneers, but these won’t whiten like natural teeth. We also don’t recommend using our products if you currently wear braces, as whitening can be uneven and uncomfortable.

How often should I whiten my teeth with WhitenUp?

We recommend waiting 2–4 weeks between full treatments, depending on the product used. Always refer to your product’s specific instructions for best practices.

Will I experience sensitivity or irritation?

Most users do not experience any discomfort when using WhitenUp as directed. If you do feel some sensitivity, we recommend taking a 24-hour break and using a smaller amount of gel. Any sensitivity is usually temporary and should resolve on its own.

How long should I wait to eat or drink after whitening?

Please wait at least one hour after whitening before consuming any food or drink. Your teeth may be more porous immediately after treatment, making them more prone to staining. Whitening before bed or during longer gaps between meals is ideal.

What is the shelf life of WhitenUp products?

Our whitening gel remains effective for 12 months from the date of purchase. To keep it fresh, store your products in a cool, dry place—or refrigerate if needed.

Are WhitenUp products cruelty-free?

Yes! We are proud to say our products are 100% cruelty-free and never tested on animals.

Do you ship internationally?

Yes, we ship worldwide! All orders ship from our Warehouse in Oklahoma City. U.S. orders typically arrive in 3–6 business days. Delivery times for international orders will vary based on location.
