The Fellatio Modification Project

by Kuang-Yi Ku

The Fellatio Modification Project is a speculative application of the biological techniques of dentistry and tissue engineering. In the field of dentistry, the oral cavity is commonly described as having only three functions: aesthetics, pronunciation, and mastication. But what about the fourth function: sex?

Left unspoken and undiscussed in dentistry textbooks, The Fellatio Modification Project looked at bodily transformation aimed at enhancing sensory pleasure during oral sex, particularly in male gay culture. Through workshops and talks, dentist and artist Kuang-Yi Ku discussed the interrelations between sex, technology and society in the pursuit of physical pleasure. The Project also raised questions about the extremes and intentions of changing and enhancing our bodies.

King’s College London dental students Anisha Gupta and Carly Billing collaborated with Kuang-Yi Ku to extend these themes to incorporate a wider range of sexual orientations and identities. Whilst some sexual health organisations recommend the use of dental dams for cunnilingus and anilingus, there is still a lack of advice on how to use them safely, effectively and in a way that is pleasurable to both giver and receiver.

The Cunnilingus/Anilingus Modification Project, by Anisha Gupta and Carly Billing, aimed to conceptualise and design a prototype for a single-use, disposable wearable device that utilises a dental dam-like barrier in a hands-free, comfortable and convenient manner, to provide an attractive, intuitive and safe sexual device.

As part of MOUTHY, Kuang-Yi Ku led a Fellatio Modification Project workshop in which participants used dentists’ tools to create oral sex toys based on dental retainers. At a talk on the same evening, Kuang-Yi Ku, Anisha Gupta and Carly Billing presented The Fellatio and Cunnilingus/Anilingus Modification Projects and facilitated discussions about the themes that they leverage, including the limits of bodily transformation in the pursuit of better oral sex.

This installation and associated events contained content of a sexual nature. Proof of age (16+) was required for entry.


Kuang-Yi Ku graduated with double master degrees with dentistry from National Yang-Ming University and communication design from Shih Chien University. He is a practicing dentist as well as a new media artist. He also co-founded TW BioArt (Taiwan bioart community) to stimulate the fields of BioArt and Science+Art in Taiwan. He has won the 1st prize of Taipei Digital Art Awards in 2015 with The Fellatio Modification Project, where he involves body modification, gender studies, queer theories, and dentistry all together. His work often deals with human body, sexuality and medicine, aiming to investigate the relationships among technology, individual and society.


Carly Billing is a 4th year dentistry student at King’s College London, with a special interest in orthodontics. As part of her undergraduate training, Carly completed a research project focusing on the mechanisms of functional devices used in orthodontic and orthognathic treatment. For her collaboration with Science Gallery London’s #MOUTHY season, along with Kuang-Yi Ku and classmate Anisha Gupta, Carly will be exploring how existing technologies used in the treatment of dental and craniofacial disorders can be adapted to modify the mouth for the enhancement of female sexual pleasure.

Anisha Gupta is a 4th year dentistry student at King’s College London, who has a background in pharmaceutical and biomedical sciences. Anisha is particularly interested in how consumable personal care products, from cosmetics and toiletries, to body jewellery and prosthetic enhancements, are used in healthcare and self-expression of female identity. In the Cunnilingus Analingus Modification project, Anisha will be exploring how female sexual pleasure can be enhanced through oral and facial products, and designing prototypes of products that aim to improve sexual health practices amongst lesbian and bisexual women, as well as the wider LGBT+ community.
