" I called the emergency line and spoke directly with Dr. Cohen on a Sunday after Thanksgiving to seek treatment for cracking my molar completely in half. Dr. Cohen and Vera, his Dental Assistant, were ready within an hour and a half to extract my tooth. I was scared and crying but I was in GREAT care. I even received a follow up phone call in the evening from Dr. Cohen to see how I was recovering."

"Dr. Cohen does superlative dental procedures. I recently had a wisdom tooth pulled and a bone graf.I hardly felt the extraction because of his expertise. His office is very clean, a pleasant environment with video screens and a good location. His office staff makes you feel comfortable and his dental assistant was very professional. I would highly recommend Dr Cohen for your dental work."

" I hate going to the dentist just like everyone, That being said, I have never had a bad experience at Dr Cohens, The hygienist was gentle and thorough. Advise me on certain things to do to make my teeth stronger and healthier. Dr. Cohen always explains everything he’s going to do before he does it and how much it’s going to cost. Like I said, I hate going to the dentist, but I do enjoy seeing Dr. Cohen and his staff. Highly recommend!

Common Dental Emergencies We Treat
Severe Tooth Pain
Sharp or throbbing tooth pain can make it hard to eat, sleep, or focus. We diagnose the cause quickly and provide prompt relief.
Broken or Chipped Tooth
A broken or chipped tooth can feel painful, sensitive, and alarming. We provide same-day treatment to restore and protect the tooth.
Dental Infections
Dental infections can cause swelling, pressure, and persistent pain. Prompt treatment helps stop the infection and relieve discomfort.
Lost Filling or Crown
A lost filling or crown can leave the tooth exposed and sensitive. We provide fast treatment to restore comfort and protect the tooth.
Knocked-Out Tooth
A knocked-out tooth needs immediate attention. Fast treatment can improve the chance of saving the tooth and stabilizing it properly.
Swelling or Abscess
Swelling in the gums or face may be a sign of serious infection. Emergency treatment can reduce pressure, treat the infection, and relieve pain.
A SUNDAY DENTAL EMERGENCY BEFORE THE WEDDING
“It was a beautiful Saturday evening when my fiancé and I decided to take a ride on our e-bikes. The next thing I knew, I was lying in the street with my chin split open, a tooth dangling, and blood everywhere.”
​
After getting stitches at the emergency room, Josh’s fiancée searched for a dental emergency dentist on Sunday. To her surprise, Dr. Cohen answered the phone and was able to see him that same day.
​
Within just a few hours, Dr. Cohen placed an implant where the damaged tooth had been, repaired the neighboring tooth, and fitted a temporary crown while the permanent one was being made.
​
Josh left the office the same day with his smile restored — just in time for the wedding.
