Tooth whitening is usually done by using oxidising chemical agents such as carbamide peroxide and hydrogen peroxide. The agent penetrates into enamel or dentine to lightens the stains or colours inside.
Home Whitening System
The dentist will create a dental mold for the patient and then customize a fitted gum shield based on the shape of the mold. The patient will be advised to wear the gum shield with the bleaching agent injected into it every night at home for the teeth whitening treatment.
At-home teeth whitening can be done at home without visiting a clinic, allowing individuals to control the frequency and time of use according to their own needs, while saving time and transportation costs. Compared to in-office teeth whitening treatments such as blue light whitening or teeth strips, at-home teeth whitening is more affordable. With appropriate use, it can maintain the whitening effect and keep teeth bright for a long time.
Furthermore, since it is an at-home teeth whitening process that is self-operated, most teeth whitening products use low-concentration whitening agents. This reduces the stimulation to teeth and gums and minimizes possible side effects.
In-office Whitening Treatment

In a session that lasts about 10-20 minutes, the bleaching process lightens discoloured enamel and eliminates stains while leaving the structure of your teeth intact and unchanged.
The process of blue light teeth whitening treatment is as follows:
1. Oral examination: The dentist will examine the teeth to ensure their healthy condition and rule out any dental diseases.
2. Teeth cleaning: Before the whitening treatment, the dentist will clean the teeth to remove tartar and surface stains, ensuring better whitening results.
3. Application of whitening gel: The dentist will apply the whitening gel evenly on the teeth and use a special blue light to activate the gel. The light triggers the release of oxygen molecules from the gel, which then breaks down stains and dirt on the surface of the teeth.
4. Mouth rinsing: After the whitening treatment, the dentist will ask the patient to rinse their mouth to remove any remaining whitening gel.
5. Exposure time: The exposure time is generally 10-20 minutes, depending on the situation.
6. Frequency: Typically, 2-3 treatment sessions are necessary to achieve the best whitening results.
