21D

21D: full jaw dental implants in the UK

21D is a British private dental clinic focused on full jaw dental implants, also known as All on 4 treatments. The company does not carry out single or sectional implants, so its services are aimed at patients who need to replace a full jaw or, in certain clinical cases, a single jaw.

The clinic presents itself as a provider of full jaw implants in the UK and operates with a clinical and support team spread across several locations. Its work is supported by proprietary technology, such as the Target Smile™ AI tool, and by a care process that spans from the initial assessment through to the definitive prosthetic restoration.

Treatments and clinical criteria

The main treatment consists of placing implants that support a fixed full jaw prosthesis. The clinic states that most of its treatments involve both jaws, although in some cases a single jaw may be treated. The decision is based on clinical factors aimed at long-term stability and function, and the company notes that designing implant-supported restorations to work alongside natural teeth, especially if they are misaligned, can be complex and may lead to less predictable outcomes.

21D regularly treats patients with bone loss, gum disease and periodontal disease, conditions it addresses so that they can become suitable candidates for treatment. The clinic does not offer single or sectional implants, so it is not the option for those looking to replace one or two teeth.

Surgical process and sedation

Procedures are carried out with local anaesthetic in the jaw area, so that the treated area is completely numb. The clinic clarifies that general anaesthesia is not permitted for full jaw dental implant procedures in general dental practice, but it offers oral medication prior to the procedure so that the patient can feel relaxed. Treatment is not carried out through the NHS or benefit schemes; it is a private clinic.

Finance and payment terms

21D offers flexible finance options through a finance partner. According to the clinic's information, the terms include a minimum deposit of £2,000, subject to application and a soft credit check that does not affect your credit score. The company presents itself as a credit broker, not a lender, and is authorised and regulated by the Financial Conduct Authority under number 976995. The company, 21D Clinical Limited, is registered in England and Wales under number 09476584.

Clinical team and locations

The 21D team is made up of clinicians and nurses registered with the General Dental Council (GDC). The clinic has professionals spread across several locations, including Warrington, Darlington, Luton, Leeds, Carlisle, Bristol, Guildford and Birchwood. The main surgery location is in Warrington and the head office is in Birchwood, also in Warrington. The company therefore operates a network of locations across the UK.

Activity and reported results

In its 2025 impact report, the clinic states that it has treated 1,258 patients, with 2,507 jaws treated and 10,028 implants placed. The company states that it has been recognised as one of the UK's fastest growing companies for two years running. It also has a patient community of more than 90,000 members, conceived as a space for support and sharing experiences.

The clinic's catalogue shows patient testimonials with accounts of improvements in eating, confidence, the disappearance of periodontal disease, pain or the use of dentures. The company also publishes informative resources on full jaw implants and patient cases.
