2 Steps on How to Make Teeth More Realistic

Learn how to add realistic depth and dimension to teeth in your acrylic portraits using these simple but effective techniques.

When painting an acrylic portrait, one of the areas that often challenges artists is getting the teeth to look realistic. Many artists fall into the common trap of painting teeth flat white, which detracts from the lifelike quality of a portrait. Teeth, however, are far from being a pure white color. In this guide, you’ll learn two simple yet effective steps that will elevate your skills in painting teeth, making them appear more realistic and natural.

Step 1: Proper Shading – Teeth Are Not White

One of the most frequent mistakes made when painting teeth is assuming they are stark white. In reality, teeth are often a light shade of gray or slightly off-white. In fact, if you compare teeth to a pure white object, you’ll notice they are significantly darker. Painting teeth flat white can give your portrait an artificial look and flatten the depth of the face.

To ensure you are capturing the right tone, use a white card to measure the value of your teeth compared to the background of your reference photo. When you observe closely, you’ll find that teeth have more of a grayish hue. By painting the teeth just a little darker than pure white, you create a realistic foundation that allows you to build up detail.

Here’s how you can achieve this:

• Mix titanium white with a small amount of raw umber dark and ultramarine blue to create a subtle grayish hue. This will be your base color for shading the teeth.
• Apply thin layers, blending the paint carefully, to ensure a smooth transition. The blend should not be too dark, but noticeably darker than pure white.
• To add more depth, mix a bit of matte medium into the paint. Matte medium helps thin the acrylic paint without compromising its color, allowing you to create soft, seamless shading that brings out the three-dimensional quality of the teeth.

By following these steps, you are creating the necessary contrast between the teeth and the bright highlights that will come in the next step.

Tip: Focus on the Surrounding Shadows

Shadows play an important role in shaping the teeth. Gums and lips often cast subtle shadows over teeth, making the edges slightly darker. Pay attention to these areas, especially around the perimeter of the teeth, to enhance the sense of depth. Remember, teeth are curved objects; shading on one side, while leaving the other lighter, will make them appear more dimensional.

Step 2: Adding Realistic Highlights – Bring the Teeth to Life

Once you’ve laid down the correct base color for the teeth, the next step is to add realistic highlights. These highlights are small but essential details that bring the teeth to life and make them look natural.

Teeth often have tiny reflections of light in certain areas, depending on the lighting in your reference photo. These highlights can be found along the tops of the teeth or on the edges where they catch the light the most. Here’s how you can effectively apply them:

• Use titanium white for these highlights. Unlike the shading, the highlights should be pure white, but use them sparingly to avoid an unnatural appearance.
• With a size 2 liner brush, carefully paint small pinpoint highlights in the appropriate spots, as seen in your reference image. The upper teeth often have highlights near the top, close to where the lips meet the teeth.
• After applying the highlights, blend them gently into the surrounding areas to avoid hard, distracting lines. The goal is to create a soft transition between the shaded and highlighted areas.

If the highlights appear too stark, you can modify the tone by adding a touch of indian yellow to warm them up. By warming the highlights, you mimic the natural hue of teeth, which tend to reflect a warmer tone due to their interaction with light and surrounding skin tones.

Tip: Be Subtle with Separation Lines

While teeth have visible separation lines, especially in close-up portraits, these lines should not be harsh. Use very faint lines to delineate individual teeth. A common mistake is making the lines too bold, which can give the teeth an outlined, cartoonish appearance. The size 2 liner brush is ideal for lightly sketching in these lines, but ensure they are soft enough to blend in with the rest of the portrait.

Additional Techniques to Improve Realism

1. Use Glazing for Depth

To create even more depth and nuance in the teeth, consider using a glazing technique. A glaze is a thin, translucent layer of paint that allows underlying layers to show through, creating a sense of depth.

• Mix a small amount of matte medium with your base gray color and apply it lightly over the teeth, focusing on areas that need more depth, such as the sides or lower parts of each tooth.
• This glazing technique allows you to build up subtle layers, increasing the realistic appearance of your portrait.

2. Pay Attention to Tooth Shape and Size

Not all teeth are the same size or shape, and these variations should be reflected in your painting. The front teeth are typically larger, while the ones on the sides taper off. Make sure to study your reference photo closely and adjust the size and shape of each tooth accordingly. This attention to detail will make your portrait look more realistic and proportional.

Conclusion

Getting the teeth right in an acrylic portrait is an essential step toward achieving realism. By shading the teeth a few tones darker than pure white and adding subtle highlights in the right spots, you can dramatically improve the lifelike quality of your portraits. Using techniques like glazing and paying attention to tooth shape will further enhance the overall effect. Follow these two steps carefully, and you’ll be well on your way to mastering the art of painting realistic teeth in acrylics.

With patience and practice, you’ll see improvements in your portrait painting skills, and your work will stand out for its lifelike qualities.
