The difference in tooth color a1 and b1

The VITA Classic Shade Guide was created in 1956 as a reference for dentists in cosmetic dental treatments. This guide presents the four main natural tooth shades, represented by a letter, and three to five progressive tooth shade levels within each shade, represented by a number. In this article, we have reviewed the types of tooth colors and explained what color we can use for our teeth, which will be useful for you to read before visiting a dentist. The 16 individual tooth shades in the guide are:

  • A—reddish brown: A1, A2, A3, A3.5, A4
  • B—reddish yellow: B1, B2, B3, B4
  • C—gray colors: C1, C2, C3, C4
  • D—reddish-gray: D1, D2, D3

In each group of letters, the first shades are the lightest colors and move towards darker shades as the number increases. For example, A1 is brighter than A2 and B1 is brighter than B2.

What system does tooth color consist of?

Tooth color may be recognized using two different systems: A color system and B color system.

In the A color system, the color of the teeth is known by using the uppercase letter A and lowercase letter A and numbers from 1 to 4. This system was created based on the color of the teeth in a standard setting specified by the VITA company. A1 or A1.A is used as one of the shades of the A system and refers to a white tooth color with a minimum cream shade and no excessive shades.

In the B color system, the color of the teeth is known using uppercase B and lowercase B and numbers from 1 to 4. This system was created by Ivoclar Vivadent. B1 or B1.B is used as one of the B system shades and refers to a white tooth color with a slight yellow tint and at most a blue-gray shade.

In short, the difference between A1 and B1 tooth color is in the different color systems, each based on different standards. Therefore, there may be small differences in the color of the teeth, so that the color of tooth A1 in system A may be a little brighter and without a creamy color, while the color of tooth B1 in system B is a little yellower and has a blue-gray shade.

What is the difference between a1 and b1 tooth color?

Logically, one might think that a1 is the whitest shade of teeth because A is the first letter of the alphabet. However, tooth shade b1 is the lightest, followed by a1. This is because of its coloring, as described in the above article. In order, the whitest shades of natural teeth are:

  • B1
  • A1
  • B2
  • A2

So, if you are planning to whiten your teeth professionally or trying to choose a shade of white teeth, B1 and A1 are both excellent choices. They represent the whitest shades of teeth that exist in nature, so they look natural and give you a bright and healthy smile.

Also, for patients who want more natural and better results from dental services and restorations such as ceramic veneers or bridges, it is better to consider B2 or A2. These shades are slightly more common in adults and have become great choices for natural-looking veneers.

Why are teeth not naturally white?

Teeth are not naturally perfectly white, and this is due to the following reasons:

  • Tooth structure: The structure of teeth consists of different layers that act like a semi-transparent curtain. The outer layer of the tooth, which is called tooth enamel, has its natural transparency and is relatively yellower than the inner layer of the tooth. Therefore, the color of the teeth is determined by the combination of these two layers, and naturally, the teeth are usually a little yellower than pure white. If you have problems with the roots of your teeth and you cannot use laminate, you can visit a dental hygienist to treat it. To solve this problem, use laminate with peace of mind.
  • Pigmentation: The color of the teeth is also related to external factors such as pigmentation. Consuming substances such as coffee, cannabis, cigarettes, tobacco, iron syrups, etc. can lead to density and absorption of color into the structure of the teeth and make them more yellow or stained.
  • Aging process: Also, with age, teeth may become slightly darker and yellow. This may be due to the natural erosion of the enamel and the penetration of color into the inner layers of the teeth.

It is important to know that the color of the teeth is diverse and is affected by genetic factors, diet, oral health, and the use of different substances. However, due to the ever-increasing technologies in the field of improving the beauty of the teeth, there are various methods to improve the color of the teeth, including toothpaste and dental hygiene products, as well as more professional methods such as teeth bleaching by dentists in Hamilton.

Criteria for choosing a dental laminate color

To choose the color of dental laminate, one should pay attention to important factors such as skin color, age, color of other teeth, eye color, and face shape, so that in case of laminate installation, it has a beautiful harmony with these components.

  • skin color

One of the most important criteria for choosing the color of dental laminate is the skin color of the face. People with dark, black, and wheatish skin color should not use the shiny white color of laminate for their teeth; Because the color contrast in the laminate and their skin will have a bad effect on their teeth or smile.

Therefore, people with white and light skin color can use brighter and brighter laminates, and in contrast to people with dark skin, it is better to use darker colors for their teeth.

  • The whiteness of the eye and its color

Among the other things that should be taken into consideration when choosing the color of the laminate is the amount of whiteness of the eyes and its color. Choosing colors that are brighter and more shiny than the whites of the eyes may make the appearance of the face look disproportionate. Knowing these points will be very helpful in choosing the color among the types of dental laminate colors to have more natural and beautiful teeth.

  • Age

Age is one of the other things to consider when choosing a natural color laminate. The color and form of the laminate should be such that it does not show the person’s age more and with a smile, the person looks younger.

  • face shape

When choosing the best dental laminate color, you should also pay attention to the shape of your face. The laminates that are made and produced by companies and laboratories are not the same and are suitable for all types of face shapes. In general, round and short laminates are suitable for elongated faces, round laminates for square faces, narrow and elongated laminates for round faces, and round laminates are suitable for heart faces.

  • Color of other teeth

If a person wants to use laminate for a limited number of his teeth, he should pay attention to the fact that the color of the adjacent teeth and their coordination with the laminate is very important; Otherwise, the difference in the color of the teeth will give a bad effect to the person’s face and smile design.
