Safety information

Teethfy Whitening Strips are designed to be safe and gentle. However, please review these important safety guidelines before use.

• Children under 18 years of age
• Pregnant or nursing women (consult your doctor first)
• People with periodontal disease or gum inflammation
• Those with exposed tooth roots or severe enamel erosion
• Anyone with known allergies to any ingredients

Whitening strips only work on natural tooth enamel. The following dental work will NOT whiten:

• Crowns and caps
• Veneers
• Fillings (silver or tooth-colored)
• Dental implants
• Bridges

If you have visible dental work on your front teeth, consult your dentist before whitening, as your natural teeth may become lighter than your dental restorations.

DO:

• Follow the recommended treatment schedule
• Store strips properly
• Consult your dentist if you have concerns
• Take before photos to track your progress

DON'T:

• Use more than once per day
• Leave strips on longer than 30 minutes
• Use expired products
• Swallow the whitening gel
• Use on children under 18

• Severe or persistent tooth sensitivity
• Gum pain or bleeding that doesn't resolve
• Allergic reaction (swelling, rash, difficulty breathing)
• Any unexpected or concerning symptoms
