Veterinary Dentist
Serving dogs and cats at veterinary hospitals across Southern New Hampshire.
Preservation first. Extraction last. Dr. Brian Dening brings 25 years of advanced dental and oral care to the veterinary hospital your pet already knows, with a real commitment to saving teeth.

Veterinary dentistry for dogs and cats.
Dental disease is the most common health problem in dogs and cats, and most of it hides below the gumline. Dr. Dening provides the advanced dental and oral care that goes beyond a routine cleaning: saving broken and infected teeth, treating gum disease that has reached the bone, repairing damaged teeth, correcting bite problems in young pets, and assessing lumps in the mouth.
Every procedure is done at your own veterinarian's hospital. He brings his own dental equipment, digital dental X-rays, and technician, while your vet oversees anesthesia and recovery. And when a tooth can be saved, he'll talk with you about saving it first. Explore veterinary dentistry for dogs and cats.
“A tooth that can be saved should be saved.”
“Around 2008, my labrador fell down the stairs and broke 2 of her canines. I did what most veterinarians would do and extracted the teeth. Not only did pulling 2 ‘healthy’ teeth break my heart, but she did not play with her toys the same after that.”
After that, Dr. Dening started looking at dentistry differently. He trained in endodontics so he could save damaged teeth with root canal therapy. His focus moved from pulling teeth to preserving them whenever he can.

Dr. Brian Dening
For most of his 25-year career, Dr. Dening has focused on the dental health of dogs and cats. As medical director at Merrimack Veterinary Hospital for 12 years, he made dentistry part of every pet's routine care. When more owners started asking for help with dental issues, he began accepting referrals from other hospitals in 2018.
He started New Hampshire Veterinary Dentistry so pets could get advanced dental care at a hospital they already know and trust. That way, there’s no need for a long trip to a referral center.
