Draw the Lips and Teeth

Draw the Top Lip


Now it’s time to draw the lips. For the top lip, start at D3. We’re going to make the top outline for the upper lip first. Be sure to sketch the top part of the top lip just below the nose that takes a dip. This trait is very characteristic of lips in general. Stop the corner of the mouth at L3.


Continuing from L3, we will curve up and keep going to draw the bottom part of the top lip now. Make sure to put the dip in the lower part of the top lip that is directly under the dip from the top part. Merge the line at the corner of the mouth to reconnect where you began at D3.

Draw the Bottom Lip


Now on to the bottom lip. We’ll sketch the top part of the bottom lip first. Pay attention to the reference photo as you draw to notice the little subtleties in the line of the lip. Draw the inner part of the inner corner of the mouth as you get to Columns K and L.


Now we’ll do the bottom part of the bottom lip. Start from L3 and work your way down the bottom curve of the lip. You should notice this line going as far down as Row 7, making the bottom lip slightly thicker than the top lip.


Reconnect with the first corner at D3.

Add Details to the Lips


Put some light lines to indicate the value changes of the top lip. Try to define the border of the round highlight near the top of the top lip. It’s kind of spotty in some places and more solid in others. A big mass is good enough for now.


There is also a thin highlight underneath the big one that extends most of the length of the lip.


Repeat this process on the bottom lip, looking for and sketching areas where color values change from light to dark. Sketch the reflected light along the bottom rim of the bottom lip, as well as the thin sliver of dark shadow just under the bottom edge.


Starting at G6, sketch the basic shape of a highlight on the lower lip. The texture of the lip breaks the highlight up quite a bit. The idea for now is to use the reference photo to sketch a very basic shape that we will polish later on.


Keep working to add more highlights. Don’t worry about getting all of it perfect. You just want to use the grid to put the basic shapes in the right places on the lip.

Draw the Front Teeth


Okay, here’s our main reason for using a grid for this drawing…the teeth!

Let’s start with the teeth in the middle, the central incisors. Start in G3 for the first of the top two front teeth. As you draw this tooth and the others, pay close attention to what is happening within each individual grid square. As yourself questions such as, “Does the line curve?” and “How much does this line curve?” See how each tooth aligns with the other teeth around it.


Keep working, moving to the lateral incisors. Try to capture the proper size and curvature of each tooth to the best of your ability. Also, pay attention to gaps between each tooth, where they occur, and how big they are. Take extra time to make sure the teeth are as accurate as you can get them compared to the reference photo. It’s far easier to fix mistakes now than it would be after we start shading.

Finish Drawing the Teeth


Next, we’ll do the canines, two on each side. There is a noticeable difference between the canines and the teeth adjacent to them. The top two canines should go high into the gum line. To see just how far, check the alignment of each canine with that of the two front teeth.


Draw the premolars next on our left side. Again, use the grid lines and the alignment of the other teeth you previously drew to decide how much height to give the tooth you are currently drawing.


Now draw the premolars on the other side. Since these teeth are receding farther into the back of the mouth, they should be getting smaller and smaller. You should also see more curvature along the side of these teeth.


Finish up drawing the outline of the teeth by drawing the molars in the very back of each side.

As far as the order in which you draw the teeth, you don’t have to always do it in the same order I did for this tutorial. I just did it this way to make it easier for you to identify which teeth I am drawing and to more easily follow along.


Just like we have been doing throughout the whole drawing, sketch some light highlights and value changes on the gums and teeth. We will use these to put more detail on these areas later on when we shade. Step away from your drawing and make a close, objective comparison to the reference photograph. Make simple tweaks to fix anything that looks off.
