Red lips and white teeth can bring out a person's temperament, which is also what many girls pursue. However, in general, if you want to get a more stable whitening result, you can't toss yourself, you need to go to the hospital for professional whitening. At present, the more commonly used methods of teeth whitening can generally improve a few shades, and how big is the change?

There are two kinds of teeth whitening methods commonly used in hospitals: chemical bleaching and physical whitening. Chemical bleaching, such as cold light whitening, and physical shading include veneers and crowns. The simple whitening of dental crowns involves more teeth grinding and less use.

Then how many color levels can generally be improved by each method.

1.Cold light whitening chemical bleaching: Generally, the teeth can be improved by about 5-10 color levels. Of course, the background color of each person's teeth is different, and the results pursued are also different. Some people get good results by raising 5 levels, while others need 8 levels for visible results. However, if the bleaching results are not satisfactory, the procedure can be repeated.

2. Physical whitening such as veneers and crowns: This kind of physical shading also needs to be compared first, and then the suitable color after restoration is determined, and then it is made into thin slices and crowns are worn on the teeth after molars. This general number is small, and it is recommended that the color of the teeth be consistent with the adjacent teeth, and the pursuit of naturalness. However, if you want more whitening, you can whiten the teeth exposed by the smile uniformly, so that the color is more harmonious, and the color is whiter. These two ways to improve the color level generally require the help of a doctor to give advice, not blindly.

Teeth whitening can generally improve a few shades (color scale) depending on the whitening method used and what everyone's needs are. If the demand is pure white teeth, then the increased color scale may be more, if the pursuit is more. The natural coordination is more, and the level of enhancement is less. The doctor will try to meet your needs according to the actual discoloration of the teeth.

After professional hospital teeth whitening, the changes in teeth are generally visible to the naked eye, so you don't have to worry about it. Of course, in some cases, there may be some gaps between the ideal results and the reality, and everyone needs to take this into consideration and choose a professional and regular hospital and doctor for it.
