The Key Ingredients of SmileFitPro™ Teeth Whitening Essence

Hydrogen peroxide  

Hydrogen peroxide is a chemical compound with the formula H2O2. It is a powerful oxidizer and is commonly used as a bleaching agent, antiseptic, and disinfectant. In dentistry, hydrogen peroxide is used to whiten teeth, as it can break down organic molecules that cause tooth stains.

Sodium hydroxide  

Sodium hydroxide, also known as caustic soda, is a highly caustic and reactive compound that is commonly used in the manufacturing of various products, such as pulp and paper, textiles, and soaps. It is also used in the production of some cosmetics and personal care products as a pH adjuster or neutralizer. In dentistry, it is used as an ingredient in some teeth whitening products.

PEG-400  

PEG-400 is a water-soluble, biodegradable liquid commonly used in teeth whitening products. It helps the active ingredients penetrate and adhere to the enamel surface, allowing for a more effective and longer-lasting whitening effect. PEG-400 also acts as a lubricant, preventing any irritation or discomfort that may occur during the whitening process.

How to Use

1、Twist the pen to dispense serum.

2、Apply a thin layer to dry teeth.

3、Leave on and avoid eating or drinking for 30 minutes.

4、Use 1–2 times daily for best results.

Does it work on Tetracycline stains?
Yes. While Tetracycline stains are deep and often difficult to treat, SmileFitPro™ helps reduce their appearance with consistent use. Results may take longer, but gradual improvement is possible.

How often should I use it?
We recommend once daily for most users. For faster or more intensive whitening, it can be used up to twice a day, depending on your sensitivity level.

When will I see results?
You may notice a temporary brightening effect immediately after application. With consistent daily use, most users report visibly whiter teeth within 5–10 days.

How long do the effects last?
You’ll experience an instant fresh, clean appearance that lasts up to 24 hours. Long-term improvements in tooth color build over 2–4 weeks of consistent use.

Can children or pregnant/breastfeeding individuals use it?
Yes. SmileFitPro™ contains no harsh chemicals, peroxide concentrations are within safe limits, and the formula is free from known toxic or hormone-disrupting ingredients. However, we always recommend consulting a healthcare provider for individual cases.

Not required. SmileFitPro™ is effective with once-daily use, but it can be reapplied after meals, coffee, or wine if desired for touch-ups.

Will it freshen my breath?
Yes. SmileFitPro™ helps neutralize oral pH and remove surface buildup that can contribute to halitosis. It leaves your mouth feeling clean and refreshed.
