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. Nowadays, however, many people want their teeth to look whiter and brighter and are requesting that their A3 teeth improve in color.
Even though the choice is ultimately up to you, a good rule of thumb to follow is to make sure your teeth aren't any whiter than the whites of your eyes for the most natural appearance.
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.
BL tooth shades measure teeth whiteness with bleaching. Ivoclar developed the system, and BL shades are whiter than the brightest shade of natural teeth. The shades are BL1, BL2, BL3, and BL4. BL1 is the most brilliant shade, and BL4 is slighter whiter than the whitest natural tooth shade.
Healthy teeth are naturally an off-white or slightly yellow hue, so don't be alarmed if they're not blindingly white. But if you would like to achieve a brighter smile, always contact your dentist for treatment – it's the safest option for your grin!
Non-White or Yellow Teeth are Unhealthy
Teeth whitening treatments usually work by stripping or entering the outer enamel layer, which makes teeth weaker if done many times. So, more often than not, yellow teeth are actually stronger than pearly white ones–so long as they're cleaned regularly.
Can my teeth become white again after turning yellow? Yes, there are a number of ways that you can help whiten teeth again after they have yellowed, from changing toothpaste and mouthwash to dental hygiene appointments.
A1 vs B1 Tooth Color
Logically, one might think that A1 is the whitest tooth shade because A is the first letter in the alphabet. However, the B1 tooth shade is actually the lightest, followed by A1. This is by virtue of its coloring (reddish yellow) as opposed to the coloring of A teeth (reddish brown).
Going from a B2 to A1 is 6 shades lighter on the color spectrum/shade guide.
The B1 shade is commonly thought to be the whitest shade, but this is not the case. The B1 shade used to be the whitest shade for natural teeth. Now, with the introduction of bleaching products, the once natural shade has become much lighter.
Healthy teeth are usually off-white or slightly yellowed, and teeth naturally darken over time. But if you notice brown, black, or green stains on your teeth, you may have a chronic condition or need a thorough dental cleaning.
When the enamel is eroded so badly, in its thinnest form your inner layer can be seen, dentin. Dentin has a natural yellow color. So, if your enamel is transparent enough to show your dentin, your teeth look yellow even if you brush them every day.

#3 Brushing Isn't Designed to Whiten Teeth

A study has confirmed what we already know – that a white and evenly spaced set of teeth makes people seem more attractive. But it has also explained the reason. It is because teeth are the human equivalent of a peacock's tail – a sign of health and genetic quality designed to help choose a mate.
Natural Enamel Thickness & Translucency
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. So your yellow teeth may be perfectly normal due to your genetics!
A2 - Light Ivory
This light ivory shade is the sort of shade you'd see on a happy, healthy, natural smile that hasn't undergone any cosmetic whitening, but that - honestly - doesn't need to. Perfect for: Anyone looking for clean, healthy and totally natural smile.
