Dental Education Lecture: Whitening congenitally stained teeth
Stained front teeth are more common in boys than in girl (Fig.1), probably because boys are more naught and more likely to get injury when they are young. When baby front teeth get injury, development of nearby adult front teeth is somewhat abnormal. When they erupt, stain has formed and gets more severe if kids do not brush well enough. Four of the bottom front teeth are also pretty yellowish (Fig.1).
To improve discoloration, regular cleaning is done first (Fig.2). You may notice that the bottom front teeth look much better than those in Fig.1. A shade guide is used.
Then in office bleaching is finished. It appears that the color of upper front teeth improve in about one hour (Fig.3,4).
Whitening congenitally stained teeth is necessary and should be done as soon as possible, because these kids are often teased by peers. The formers have low self esteem. It happens to this 9-year-old boy.
