Dr Jose Cordero Bayo

BDS, MClinDent Implantology


GDC Number: 170042

Jose has been practicing in private practice since 2009.

A truly caring dental surgeon who has previously been in private practice in Worthing for many years where he has built up an admirable reputation with his amazing use of digital technology and extremely happy patients! Being a local Hove resident himself, Jose brings with him an immense wealth of experience and enthusiasm to provide the highest level of dental care TwentyOneDental are renowned for.

A sought after Dental Surgeon, Jose also brings with him additional experience from the world famous Harley Street, London where his excellent reputation is also well known.

Particularly so for achieving outstanding results using digital dentistry not forgetting his numerous skills and experience including advanced oral surgery, Jose has an extremely sensitive and caring approach with all his patients.

Passionately committed to keeping abreast of the latest advances in dentistry through post graduate education courses, Jose has additional qualifications in Surgical & Restorative Implantology, Endodontics and a Masters in Clinical Dentistry in Implantology.

Jose is also a certified Invisalign GOLD practitioner, providing invisible orthodontics for teenagers and adults.

Being committed to advanced technology in dentistry is just one of many reasons why Jose was keen to work here at TwentyOneDental. With our digital dentistry technology, patients comfort is enhanced using what is often called by many as the future of dentistry.

With the use of iTero provides so much more precision for restorative dentistry such as crowns, bridges, inlays, implants.

The use of intra oral scanners make the overall experience so much more comfortable for our patients, particularly for those who suffer from a strong gag reflex. The associated discomfort caused by traditional impressions is also removed. With the use of such digital technology, iTero is a cutting-edge scanner that eliminates the need for impressions, enabling Jose to create an even more accurate fit for Invisalign® aligners. Traditional impressions are often messy and trigger a gag reflex in some patients, making them an uncomfortable part of the Invisalign® preparation process.

Our patients can entirely avoid this problem with iTero. The scanner not only provides a more accurate digital impression – it also powers the Invisalign® Outcome Simulator, which helps the patient visualize how their teeth will look at the end of the treatment process. The high level of accuracy also minimizes patients time to re-take impressions.

Having the same ethos as everyone here at TwentyOneDental, Jose:

  • Listens to you and understands your concerns
  • Provides exemplary dentistry tailored to your needs
  • Makes you feel absolutely comfortable and at ease throughout your treatment process
