Can You Modify Teeth in Call of Duty: Ghosts Extinction (Xbox One)?

No. Call of Duty: Ghosts Extinction mode does not allow character appearance customization of any kind—including teeth, facial features, or body type.

You can only select from preset character skins/outfits unlocked through gameplay (prestige, challenges, DLC). There are no sliders, morphs, or dental options.

Games with Deep Character Customization (Including Facial Details)

• Black Desert Online / Elder Scrolls Online — Extensive face/body morphing.
• Cyberpunk 2077 — Detailed facial customization including teeth options.
• Red Dead Online — Robust character creator.
• WWE 2K series — Deep creator suite.

CoD Extinction is a horde-mode co-op experience focused on loadouts and teamwork, not visual identity.
