Q
How long can the effects of teeth whitening be maintained?
Regular teeth cleaning and polishing can remove most tooth stains and achieve teeth whitening. However, besides tooth stains, there are many factors that can cause teeth to turn yellow, such as aging, frequent consumption of tea or coffee, smoking leading to pigment deposition, etc. These issues cannot be solved solely by teeth cleaning and polishing. Therefore, if you want to have perfectly white teeth, We Care Dental Center's teeth whitening service at our dental clinic in Macau would be a great choice for you.
In Macau, blue light teeth whitening is a common and effective method for teeth whitening. It utilizes high-intensity blue light to activate the whitening agent, which penetrates the enamel through oxidation, removing the deposited and dull pigments. The benefits of this method include its speed, safety, long-lasting results, and significant effectiveness.
The general process of teeth whitening is as follows:
Before starting, it is recommended to have a dental cleaning and polishing to prevent dental plaque from infecting the teeth.
By comparing the model teeth of different colors with your current teeth, it will be convenient to evaluate the effectiveness of the treatment later on.
Secure the oral cavity with dental instruments and apply protective gel on the gums to prevent gum irritation from blue light or bleaching solutions
Apply teeth whitening gel onto the teeth
Repeatedly expose the teeth to blue light, which may cause a temporary sensation of sensitivity or discomfort
After completion, thoroughly rinse off the protective gel and bleaching solution
Q
How long can the effects of teeth whitening be maintained?
A
The effects of blue light teeth whitening are generally stable and long-lasting. However, several factors can influence the effectiveness of teeth whitening, such as genetic factors, lifestyle and dietary habits, aging leading to tooth discoloration, smoking, and the impact of medications, among others. Therefore, the duration of having white teeth can vary from person to person.
Q
Does teeth whitening cause sensitivity?
A
牙齒敏感主要源於美白劑會暫時打開牙齒表面的牙本質小管﹐使牙本質暴露﹐進而對冷、熱、酸、甜等刺激產生敏感反應。這種敏感通常是暫時性的﹐多數人在美白結束後幾天到一兩週內會逐漸緩解。
Q
Does teeth whitening harm the teeth?
A
美白劑含有硝酸鉀和氟化物，多項研究證實有減少蛀牙、減輕敏感不適、保護牙齒健康的效用，對牙齒反而有好處。
