A1 Tooth Shade: Is It Really White or Just Natural?

A1 Tooth Shade: Is It Really White or Just Natural?

One of the most common questions patients ask when it comes to tooth colour is:

'Is A1 tooth shade really white, or does it just look natural?'

A1 tooth shade is included in the VITA Classical Shade Guide, one of the most widely used colour classification systems in dentistry, and is considered 'natural white' in aesthetic dental treatments. In this article, we will explain what A1 tooth shade means, how it differs from B1, in which treatments it is preferred and how it is scientifically evaluated.

What is A1 tooth shade?

A1 tooth shade is the lightest shade of the A group in the VITA Classical colour scale.

In the VITA system, tooth colours are divided into four main groups: A, B, C and D:

Group A: Reddish-brown undertones

Group B: Reddish-yellow undertones

Group C: Shades of grey

Group D: Reddish-grey tones

A1 is considered one of the lightest and most balanced natural white shades among these groups. For this reason, it is frequently preferred by both dentists and dental technicians.

Is A1 tooth colour white or natural?

From a clinical point of view, A1 is defined as a healthy and natural white tooth colour, not 'too white'.

This point is especially important because the aim of aesthetic dentistry is not always to achieve the whitest shade, but to achieve a colour that is compatible with the face and mouth structure.

Perception of tooth colour according to scientific studies;

  • Light conditions
  • Skin tone
  • Lip colour
  • Restoration in the neighbourhood

is influenced by many factors. For this reason, A1 is perceived by many as the 'ideal white' in everyday life.

How to determine A1 tooth shade?

Visual (classic) method

In the traditional method, the dentist assesses the tooth colour visually with the help of a shade guide. This method is fast but may vary depending on light and personal perception.

Digital measurement methods

Today, digital systems are preferred for more objective results:

  • Spectrophotometers
  • Intraoral scanners
  • Digital photo analysis systems

The scientific literature shows that spectrophotometers in particular give more consistent results by measuring tooth colour over the CIELAB colour space.

In which treatments is A1 tooth shade preferred?

Teeth whitening

In many patients, the targeted result after professional whitening is A1 level. However, factors such as initial colour, enamel structure and age affect the result.

Lamina and veneer treatments

A1 is one of the most preferred shades for porcelain laminae and veneers.

The reason is the low risk of an 'artificial' appearance over time.

Crowns and veneers

Due to its compatibility with natural teeth and stable results in laboratory production, A1 is considered a safe choice for fixed prostheses.

What is the difference between A1 and B1?

What is the Difference Between A1 and B1?
Feature A1 Tooth Shade B1 Tooth Shade
Whiteness Level Natural white Brighter white
Undertone Slightly warm Cooler
Perceived Naturalness Very high More noticeable
Clinical Use Most common Aesthetics-focused
Long-term Appearance Balanced May look artificial over time

Is A1 tooth shade suitable for everyone?

Although A1 tooth shade is suitable for most patients, it may not be ideal for everyone.

In particular:

  • B1 may be more aesthetic in very fair-skinned individuals
  • In the more mature age group A1 looks more natural
  • Patients with social media orientated 'very white' expectations may find A1 insufficient

Therefore, colour selection must be made with clinical evaluation.

Is A1 tooth shade permanent?

After bleaching: The colour may return slightly over time

Crowns / veneer: A1 colour stable for many years

Coffee, tea, smoking: may adversely affect colour stability

Scientific studies show that shade A1 shows high colour stability in restorative materials.
