high quality You can smile, drink and smoke freely while wearing it, and it will not make you feel any discomfort in your mouth. Fits securely and comfortably over upper teeth. No more slurred speech, and a more charming smile. Safe cosmetic braces that eliminate the need for a visit to the dentist. Teeth that are missing/crooked/stained/broken can be fitted with crowns, veneers, partials and bonding. These teeth are not suitable for adhesives, so your teeth will be more beautiful and natural-looking. Perfect Smile dentures are a great alternative to expensive braces. How to use 1. Place the tooth in a cup of hot (almost boiling) water for 1 minute. This will make them flexible and ready for customization. 2. Using a mirror, Instant Smile teeth are securely attached to your existing teeth. Press them firmly against the teeth and use your thumbs to gently press the impression material behind the natural teeth. 3. After 30 seconds, gently release the tooth from your mouth and cool it in a glass of cold water. The impression material will turn white as it hardens. Note: Due to the light and screen setting difference, the item's color may be slightly different from the pictures. Please allow slight dimension difference due to different manual measurement.
