Dental emergencies can be stressful for both children and parents. Prompt treatment helps address pain, prevent complications, and protect your child’s oral health.

If you are a registered patient, please call our office right away if your child has a fractured tooth, a knocked out tooth or other dental trauma. We make every effort to see emergency patients the same day. After hours, a doctor is on call to help guide families through urgent situations.

If your child has swelling or a fever, proceed to the nearest urgent care center or call 911.

Dr Sam goes above and beyond with caring for my 14 yr old boy (one with ASD) & 10 yr old boy. We are more than grateful for his care! His staff and he go above and beyond to make sure both boys get excellent care. For the first time ever, my son w/ ASD was able to have X-rays done without being under general anesthesia! The true team effort of extra staff support, knowledge about what can suppress shallow gag reflexes, understanding how to communicate to Luke & preciseness all just came together for the goal of full teeth X-rays! It was such a fantastic moment! We were all so proud of him, & I think he was proud of himself too. We’ve tried all his life and yesterday was the day! Thank you ALL!!

Always a GREAT Experience! When I was their age dental appointments were always worrisome, with the expectation of pain and discomfort. Not for my boys! I believe that they may even look forward to seeing Dr deLorme!

Dr. Sam and his staff were wonderful. Very kind and hospitable. He did a great job educating me and giving me techniques for an easier time brushing my son‘s teeth. He was also very understanding to my desire to abstain from using fluoride toothpaste with my son.He recommended it, but was very good about not being pushy and he respected my decisions. He offered an alternative fluoride, free toothpaste. All of his staff were very sweet and were great with my son.

Dr. John and his team are amazing! He thoroughly explained to us with visuals what was going on with our kids teeth, provided options. We are thankful to Dr. John and are happy we made the switch! I was tired of seeing a different dentist every time at my prior place. Ease of making appointments was also important.

Dr. De Lorme and his team are amazing! We recently took our son in for his second visit and had the best experience. I also went to Dr. De Lorme as a child and it’s fully circle bringing my own children now! My son felt comfortable and loved going to the dentist because of how friendly and accommodating everyone was! Would definitely recommend to anyone looking for an amazing pediatric dentist!
