Teeth Whitening

Q: How long does the whitening effect last?

It varies with individual diet and care, but usually lasts about 6 months to 1 year. Reducing stain-causing foods and brushing thoroughly extends the duration.

Q: After the procedure, will my teeth turn yellow again like before?

Since teeth are living tissue, the color can gradually return over time. However, they will not darken completely as before the procedure, and you can keep the brightness through regular whitening.

Q: How many sessions do I need?

Blanche Dental's whitening usually shows a noticeable effect with just one visit a day (2-3 consecutive sessions). If you want a brighter level or have severe staining, we recommend additional sessions at one-week intervals.

Q: Are there cases where whitening doesn't work?

In the following cases, treatment other than regular whitening may be needed. At Blanche Dental, we first check through precise diagnosis whether whitening is suitable before the procedure.

Q: Does it hurt a lot (sensitivity) during the procedure?

There are individual differences, but Blanche Dental carefully applies gum protectant and adjusts the agent concentration and time according to each patient's tooth sensitivity. Minimizing sensitivity while maximizing the effect is the core of Blanche whitening.

What Is Teeth Whitening

A treatment that erases the cause of staining and restores translucency

Pigments from coffee, tea, and food seep into the microscopic pores (dentinal tubules) on the tooth surface and turn teeth yellow. Aging can also darken the inner dentin. Blanche Dental's whitening uses special agents that trigger an oxygen reaction, breaking down only the stained organic matter without damaging the tooth structure. By raising light transmission, it restores a clear, clean shade from deep within the tooth.
