Using a four-shade guide, most people have teeth that are A3 in color, meaning that they are somewhat reddish brown. This is considered the average, natural tooth shade.
Within these shades, either A, B, C or D, the shades are classified by a number from the lightest, 1, to the darkest and most intense, 4. Thus, a shade A1 will be a reddish-brown shade, just like shade A2, but the latter will be darker.

Teeth that have yellowed with age
As we age, the enamel becomes thinner due to wear and tear, revealing the underlying layer of tooth structure called dentin. Dentin is naturally yellowish and cannot be lightened with teeth whitening products.
Yellow Teeth
This is the most common color of teeth. A light-yellow color indicates a strong healthy smile. The natural color of your dentin, the layer of tiny tubules that lies beneath your enamel and connects to the dental nerve in each tooth, is yellow.
This is the most popular shade choice by far. A1 is the brightest that teeth can look naturally. It is a bright look. A1 gives the appearance of somebody who has had a professional tooth whitening procedure.
Yellow teeth are stronger than bright white teeth.
Natural Enamel Thickness & Translucency
Enamel is on the surface of every tooth and it has a natural hue of white. However, the underlying dentin layer has a slightly yellowish color. This yellowish hue shows through the enamel in almost everyone, but more so for those with naturally thinner or more translucent enamel.
The average shade for a tooth is A3, this is considered a normal colour and around 70% of the population have natural teeth which are within this range. A B1 shade is considerably lighter than A3 and is generally considered the lightest naturally occurring shade.
In spite of our obsession with whiter teeth, most healthy teeth tend to have a light yellow hue. The outer layer of your teeth – the enamel – is a blue-white color. The middle layer – the dentin – is a thick tissue with a slightly yellow tinge.
A B2 is a relatively natural tooth shade and not considered to be too 'Hollywood' white.
Teeth Are Often Stained
Coffee, cola, berries, tomato sauce and wine all can stain teeth. Even tetracycline antibiotics and fluoride can cause stains at times. Even if you brush every day, your teeth will likely become stained over time if you regularly consume items that cause stains.
Answer: Is B1 too yellow? Historically B1 was considered a very light shade until people started bleaching their teeth. Now most people prefer the brighter bleached shades for their veneers. Also you need to take into account the color of the surrounding frame, your lips gums and skin tone.
A good rule of thumb when determining how white your teeth should be is to look at the whites of your eyes. Whether whitening at home or undergoing treatment by a professional dentist, you should be aiming for a shade of white similar to that of your eyes.
Your veneers should never be whiter than the whites of your eyes. Fairer skin tones should pick from the whitest colors available. Since fairer skin doesn't contrast with the color of the teeth very much, a lighter shade is necessary to make your teeth appear white.
One word: veneers. Cosmetic dentistry (veneers and no-prep veneers in particular) is the only sure-fire way to get a Hollywood-level smile. In the 80s and 90s, veneers were incredibly popular because they could give most anyone a perfect smile in only a few dental appointments.
Because we place them over your natural tooth, you can have them in almost any shade you like. If you want a perfect B1 shade, it is possible with dental veneers. The most effective whitening method will vary from person to person.
A1 shade is a shade at the top end of the international shade guide for tooth colors. A1 used to be considered a very white shade but with all the bleaching shades now, there are even whiter shades yet.
Their Permanent Teeth Are Starting to Erupt
Permanent teeth have more dentin (the second layer of the tooth below the enamel) and this has a yellowish color. Enamel is slightly translucent, so the color of the dentin may show through.
