Welcome to NJS Dental


Established in 1999, our private clinic is located in the centre of Carmarthen. Nicholas Sheehan took over as principal in 2015 after working as an associate since 2011.

Our focus is on prevention and our goal is to help you achieve and maintain healthy teeth and gums.

We cover all aspects of  general dentistry and in addition offer a wide range of cosmetic services including teeth whitening, invisible teeth straightening procedures, veneers, composite bonding and we have a CEREC machine on site which can produce strong and highly aesthetic restorations in a single visit.

Our highly skilled professionals will always discuss treatment options and costs in detail and we will try our best to put you at ease and be as gentle as possible.

We have a full time hygienist available who will help to prevent dental decay and gum disease by cleaning your teeth on a regular basis and providing education about how to care effectively for your teeth and gums, and the affects of diet on oral health.

We operate an out of hours emergency service for our registered dental patients.

We have a spacious waiting room with tea/coffee available. All three surgeries have air conditioning and accessible for wheelchair users. Our new childrens waiting room is also very popular!

Denplan Excel

How it benefits you as a patient

Denplan Excel certification programme is an additional mark of quality available to Denplan member dentists, and is tailored to support and encourage practices to reach their full potential as providers of excellent customer care. To join Denplan Excel, a practice must demonstrate continued commitment to quality improvement.

Practices must also pledge to use the most appropriate procedures and dental knowledge to ensure patients are receiving the highest standards of care from start to finish, and encourage patients to be involved in any decision making stages. Denplan Excel members can also access DEPPA, an online tool your dentist can use at your check-up that helps you and your dentist examine your current oral health status and identify any future risks.


  • Nick is proud to be a Denplan Excel certified dentist
  • It is a visible sign of our commitment to offering you the highest level of care
  • The Denplan Excel certification programme provides a simple and effective way for patients to understand all aspects of their oral health
  • It provides you and us with assurance that we are meeting or exceeding statutory requirements  and are able to measure and monitor the oral health of our patients via the Oral Health Score © or Denplan Excel PreViser Patient Assessment (DEPPA) so that you are completely involved in your dental care and treatment.

Our team of experienced dentists, hygienist and nurses are eager to help.
