Teeth whitening trays are made of clear plastic

First, you need to see the dentist directly for examination and to see if your teeth are healthy enough to perform the whitening. If there are signs of disease, the dentist will prescribe a treatment first.

After the examination, the dentist will clean the oral cavity and get the marking of the teeth, the marking will be sent to Labo for trays manufacture.

Finally, before giving you the bleaching trays to whiten your teeth at home, the dentist will give you specific instructions on how to do it and schedule a follow-up visit to monitor the progress.

When you go for the whitening trays method, follow these steps:

- Step 1: Maintain oral hygiene after dinner by brushing, flossing, and use mouthwash. Then, give a sufficient amount of gel into the trays and insert into your teeth.

- Step 2:  You hold the trays in your mouth for about 30 minutes - 1 hour so the gel has time to absorb deep into the enamel. In the meantime, you can go on with your daily routine such as reading, working, studying, etc.

- Step 3:  Remove the trays and rinse your mouth thoroughly with water

Patiently do so until you used up two syringes combined with periodical dental visits as instructed by the doctor to achieve the highest efficiency. In addition, you should also avoid consuming acidic and colored foods such as red wine, beer, tea, coffee, soy sauce, tomato sauce, etc.
