Alexander T. Kim, D.M.D
Practice Limited to Endodontics


 Pursuant to the executive order issued by Governor Murphy our offices are effectively closed until further notice. As healthcare providers, our first responsibility is to the health and safety of the ones we serve- our patients and our community. This decision was not taken lightly, and is based on public health recommendations and out of an abundance of caution, in an effort to combat the spread of COVID-19 virus.

As part of Governor Murphy's executive order dental offices can and shall remain open to treat dental emergencies.

During this time if you have a possible dental emergency:

Call: 609-771-1200 and it will be directed to an employee who will answer your call, leave a message if there is no answer and someone will get back to you as soon as possible. They are consistently in contact with the doctor.

*All existing appointments will be postponed until the office re-opens. At which point we will contact you to reschedule existing appointments.

As you know we value all your questions and we will get back to you as soon as possible. As we continue to navigate these unprecedented times, community remains at the heart of what we do. Despite the challenges presented by the coronavirus (COVID-19) pandemic, we are committed to offering our support every step of the way.

Dr. Alexander Kim DMD & staff

Trusted Endodontist in Lawrenceville, NJ

Dr. Alexander T. Kim specializes in treating patients in the Lawrenceville and Princeton areas who need root canal therapy or related services.

When you have a toothache, chances are tooth decay has spread into the pulp, irritating the nerves. Dental injuries also often damage the innermost portion of teeth and usually require endodontic intervention.

Referrals for Endodontic Services in Lawrenceville

When you visit your general dentist with a toothache or injury, there is a high likelihood that they will recommend a root canal. This usually means being referred out to a specialist like Dr. Kim. Our Lawrenceville Endodontist receives many referrals from other dentists for root canals. He also accepts patients who come to him directly for the following services:

  • Root Canal Therapy
  • Root Canal Retreatment
  • Cracked Tooth Diagnosis
  • Apicoectomy & Apexification
  • Pulpotomy & Pulpectomy
  • Bone Grafting
  • Dental Emergency

Dr. Kim also welcomes patients who are seeking a second opinion when faced with potential tooth extraction. If you’ve been told a tooth needs to be removed and replaced, it’s worth your time to have a specialist determine if there is any chance of preserving your natural tooth with a root canal

Your Comfort Matters

Our Lawrenceville dental specialist understands that many patients have fears or phobias related to dental procedures and offers a choice of nitrous oxide or oral sedation for those who need it. He takes a gentle approach and thoroughly explains your treatment options and what they entail.

Accommodating, Convenient, and Flexible

Your busy life can interfere with getting the dental care you need. Our entire team works hard to accommodate your schedule and when you arrive for your appointment, we don’t keep you waiting.  If you have a dental emergency, restoring your comfort is our priority, and Dr. Kim makes every effort to see you quickly.

World Class Endodontics Provided in Friendly Environment
