Take-Home Teeth Whitening Kit in Bangkok – 4,000 THB
La Posh Dental Clinic · Bangna and Ram Inthra-Ratchada · Open daily 10:30–19:30
How does home whitening work?
The dentist takes an impression or scan to make thin clear trays that fit your teeth exactly. You place whitening gel in the trays and wear them for the time prescribed. The gel gradually breaks down stains inside the tooth, giving a controlled, step-by-step result. You can keep the trays for top-ups later.

How soon will I see results?
Most people notice a change within a few days to 1–2 weeks, depending on their starting shade and how regularly they use the trays.
Is home whitening safe?
Yes, when you use dentist-prescribed gel and custom trays as instructed. Temporary sensitivity is the most common side effect.
Home or in-clinic whitening – which is better?
In-clinic whitening gives faster results in one visit. Home whitening is gradual and costs less. Many people use a home kit to top up after in-clinic whitening.
How long do the results last?
It depends on habits such as coffee, tea and smoking. You can top up with the same trays as your dentist advises.
Can crowns or veneers be whitened?
No. These materials do not change colour. The dentist will plan so that they match your natural teeth.
