Nighttime tooth protection – with a physical UKCA-accredited EVA barrier

EVA material forms a cushioning layer between upper and lower teeth that reduces direct enamel contact and spreads bite forces across the guard. UKCA accreditation indicates conformity with applicable UK regulations.

A physical barrier helps guard against fractures, enamel wear and gum recession overnight, offering practical protection while asleep.

Custom fit at home – with multiple sizes included in the pack

Each pack contains four mouth guards available in small and large sizes plus two retainer cases to store preferred pieces. The multiple-size approach allows users to select the most comfortable option without a dental appointment.

Home fitting removes the need for a clinic visit and makes it straightforward to find a closer fit for nightly use.

Durable, dentist-endorsed construction – with reusable EVA material

Manufacturing uses durable EVA described as long-lasting, and the product messaging notes endorsement by dentists under the ClenchNoMore name. Included retainer cases help maintain hygiene and prolong usable life.

Durability and professional endorsement mean guards last through repeated nightly use, providing consistent protection and value.
