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


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.
