A Talleyville guide. Published August 28, 2026 · 5 min read ![Veterinary surgeon in our Wilmington DE clinic reviewing a digital intraoral dental radiograph during a canine tooth extraction](/images/featured/veterinary-surgeon-reviewing-a-digital-intraoral-d.webp) ## Two things that separate good canine dentistry from adequate **Digital intraoral dental radiography is X-ray imaging taken from inside a dog’s mouth to show tooth roots and jawbone below the gumline. A regional nerve block is a local anesthetic injection placed beside the nerve supplying one section of the jaw, so that whole area is numb during and after surgery.** If you take one thing from this guide, make it this: when comparing dental quotes for your dog, the two questions that matter most are whether X-rays are included and whether nerve blocks are included. Both are standard in our dental and oral surgery service [/dog-dental-oral-surgery/ →](/dog-dental-oral-surgery/) for Talleyville dogs. Both are often missing elsewhere, and their absence is usually why the headline number is lower. ## What lives below the gumline ![Digital dental radiography equipment and sterile instruments in a modern veterinary dental suite](/images/misc/digital-dental-radiography-equipment-and-sterile-i.webp) Looking in a dog’s mouth shows the crowns: tartar, gum recession, and teeth that are obviously broken or discolored. Roughly two-thirds of each tooth is below the gumline, and so is most canine dental disease. **Digital intraoral radiography** reveals: - **Root abscesses** under a crown that looks completely normal from above - **Alveolar bone loss**, which sets the periodontitis stage and decides whether a tooth can be saved - **Resorptive lesions**, where the tooth is being broken down from the inside - **Retained root fragments** left behind by previous extractions - **Root fractures** that are invisible above the gumline - **Unerupted or malformed teeth**, particularly in small breeds Without radiographs, a dental procedure treats what can be seen and leaves what cannot. Owners tell us the mouth looked better afterwards, but the dog still would not chew on that side. > **X-rays are also taken after the extraction, not just before.** > > A post-extraction film confirms the root came out whole. A retained root fragment is the single most common cause of ongoing pain after a dental performed without radiography. ## What nerve blocks actually do A regional nerve block places local anesthetic beside the nerve that supplies a whole section of the jaw. An **infraorbital block** numbs the upper jaw on that side, and an **inferior alveolar (mandibular) block** numbs the lower. Three benefits follow. **The general anesthetic can run lighter.** If the surgical site is truly numb, the dog does not need to be as deeply anesthetized to stay comfortable. Lighter anesthesia means better blood pressure, better circulation, and a faster recovery, which matters most for the senior dogs who need most dental work. **Your dog wakes up comfortable.** Without a block, pain arrives as a surge exactly when the anesthetic wears off. With one, the block is still working through recovery and the oral pain relief has time to take effect. **Less anesthetic drug overall** means less for the body to process and clear, which is directly relevant for dogs with reduced liver or kidney function. ## The anesthetic conversation Dental procedures are long by veterinary standards, which makes the supporting protocol matter more, not less. Pre-anesthetic blood screening happens before a date is confirmed, so the protocol is built around your dog’s actual liver and kidney values. Patients are kept warm on a heated table, because heat loss during a long open-mouth procedure slows drug metabolism and prolongs recovery. Blood oxygen, ECG rhythm, blood pressure, and core temperature are monitored continuously. Owners often worry about anesthetizing an older dog for dental work. The fair comparison is with leaving painful, infected teeth in place, which is not a neutral alternative. ## What to ask when comparing quotes 1. Are **full-mouth dental radiographs** included, or charged separately? 2. Are **post-extraction radiographs** taken to confirm complete removal? 3. Are **regional nerve blocks** included on every extraction? 4. Is **pre-anesthetic bloodwork** included? 5. **Who monitors** your dog, and which parameters? ![Anesthetised dog on a warmed dental table with a nurse recording vital signs](/images/misc/anesthetised-dog-resting-on-a-warmed-dental-table-.webp) Talleyville Dog Surgery prices dental procedures from $150 to $950 with all five included, and complete cleanings from $295. A cheaper quote missing three of those five is not the same procedure. Guide FAQ ## Questions owners ask 01Are dental X-rays really necessary for dogs? Yes. Roughly two-thirds of each tooth sits below the gumline, and that is where most canine dental disease is found: root abscesses under normal-looking crowns, bone loss, resorptive lesions, and root fragments from earlier extractions. A visual exam cannot see any of it, which is why X-rays are included in our pricing. 02Do nerve blocks reduce pain during dental surgery? Substantially. A regional block numbs a whole quadrant of the mouth, so the general anesthetic can run lighter, which is safer for older dogs, and your dog wakes without a sudden wave of pain. Pain relief then continues at home. 03Are X-rays and nerve blocks included in your prices? Yes. Digital dental radiography and regional nerve blocks are both included in our dental pricing, which runs from $150 to $950 per procedure. If another quote is cheaper, check whether both are included before comparing. ### Still have questions about your dog?
