We all know how important a realistic mouth can be to enhance the overall sexdoll experience. Chinese realistic doll manufacturers have come a long way to help doll enthusiasts achieve a mouth that more and more resembles 'the real thing'.

The Evolution of Mouth Enhancements: Removable TPE Tongues

Until a few years ago, the only addition available was the TPE removable tongue (see pictures below). This is normally still available in the absence of more recent upgrades, or if the buyer just looks for a free-of-charge simple tongue to use occasionally.

Integrated Tongues and Uvulas

Later on, WM Dolls introduced the integrated tongue with uvula. This is by now available on almost all WM Dolls heads, as well as on several other brands in our catalog. The integrated tongue and uvula is normally a fee-paying add-on that you can find in the customization section. If you don't find this option in the customization section, it means it's not available. However, watch out for changes in the future, as some manufacturers might start adding the tongue and uvula as a default feature or offering it for free during some promotions. In this case, you'd be advised of the change in the product description or promotion info.

Innovative Removable Teeth and Tongue Kits

The largest and possibly most innovative manufacturer, WM Dolls, launched an interesting and peculiar set of removable teeth and tongues in 2018. The kit can be added in the customization of your WM Dolls and can also be purchased separately. The kit should be compatible with the mouths of most brands in our catalog. We advise considering this add-on only if your doll is free from an integrated tongue, and the shape of the mouth allows the kit to be installed successfully (smiling mouths, for example, would be less suitable).

The Next Level: Moving Jaws and Upgraded Mouths

The latest mouth enhancement is the moving jaw, often associated with a more realistic set of integrated teeth. As of October 2022, three brands in our catalog offer this exciting option. Sanhui introduced its 'adjustable mouth' feature in early 2020. You can read our detailed breakdown in our blog entry about Sanhui's adjustable mouth. As you can see, this option is available on a good number of Sanhui heads. We don't have an oral sex demonstration of Sanhui's adjustable mouth, so we can't say if there's an improvement in this respect over the regular mouth.

As we're writing, Jiusheng and WM Dolls are launching their own upgraded mouths. Jiusheng currently offers this option on three heads. Below is an extensive video demonstration, including an impressive oral sex test. As you can see in the footage, Jiusheng's upgraded mouths come with better-sculpted teeth as well.

WM Dolls' ROS (Real Oral Sex) promises a much-improved oral sex experience thanks to a series of enhancements. Watch the video demonstration below to see the ROS feature in action. We haven't received our own oral sex video yet; however, we're sure WM Dolls' claim has solid bases (see banners below for details).

Slightly Open Mouths and Future Enhancements

Heads with the moving jaw tend to have a slightly open mouth as a default feature. This is clearly shown in the following video, which compares the FanReal Doll head 'Maria' in regular and soft silicone.

What's next? First, we expect the ROS feature to be rolled out on more and more heads. At some point in the future, the ROS mouth will likely become the default for all quality sexdolls. After that, it's hard to imagine further enhancements that don't include any form of robotization. One thing is sure: with Chinese realistic doll manufacturers' inexhaustible inventiveness and desire to excel, the future of sexdolls' mouths looks pretty exciting.
