Choosing the best treatment path for periodontal disease

Bottom line

A new Veterinary Practice News clinical review argues that the real challenge in periodontal disease isn’t spotting it, but deciding how to treat each tooth based on tooth-by-tooth severity. That lines up with current small-animal dental guidance: a visual exam can suggest disease, but a complete diagnosis requires anesthesia, periodontal probing, and full-mouth intraoral radiographs, because clinically important pathology is often hidden below the gumline. Treatment options range from professional cleaning and closed or open root planing for earlier disease to local antimicrobials, periodontal surgery, or extraction when attachment loss, mobility, furcation exposure, or endodontic involvement make a tooth a poor candidate for salvage.

Why it matters: For veterinary professionals, this is a reminder that “dental cleaning” and “periodontal therapy” aren’t interchangeable. AAHA’s dental guidelines emphasize that awake dentistry is cosmetic, not therapeutic, and that treatment planning should be based on staging, radiographs, and prognosis for each tooth. That has practical implications for case estimates, client communication with pet parents, anesthesia planning, and decisions about when referral is warranted for advanced periodontal surgery versus when extraction is the most predictable, welfare-forward option. (aaha.org)

What to watch: Expect continued emphasis on earlier anesthetized dental assessment, especially in small-breed dogs and cats, where guidelines say full-mouth radiographs and tooth-by-tooth probing can catch disease before teeth become nonsalvageable. (aaha.org)

Key facts

Topic
Periodontal disease treatment must be decided tooth by tooth
Diagnosis
Awake oral exam is only preliminary; anesthesia, probing, and full-mouth intraoral radiographs are needed for diagnosis
Hidden pathology
Clinically important disease can be missed below the gumline without imaging
Commonness in dogs and cats
By 3 years of age, most dogs and cats have some level of periodontal disease
Cats
About 85% of cats over 6 years of age are affected
Dogs
Studies suggest 80% to 90% of dogs older than 3 are affected
Treatment options
Professional cleaning, root planing, gingival curettage, open periodontal therapy, local antimicrobials, regenerative procedures, or extraction
Poor prognosis signs
Increased mobility, attachment loss, furcation exposure, or endodontic involvement
Awake dentistry
Cleaning an awake animal improves appearance, but not periodontal health

Periodontal disease is easy to recognize and much harder to manage well, according to a new Veterinary Practice News review focused on choosing the best treatment for each affected tooth. The core message matches current veterinary dentistry guidance: gross tartar and gingivitis may be obvious, but the real clinical work starts once the patient is anesthetized and the team can probe, chart, and radiograph the entire mouth to determine which teeth are treatable and which are not. (aaha.org)

That matters because periodontal disease remains one of the most common disorders seen in companion animal practice. AAHA says that by 3 years of age, most dogs and cats have some level of periodontal disease, while Cornell notes studies suggesting 80% to 90% of dogs older than 3 are affected. In cats, Cornell reports periodontal disease is the most common dental problem and estimates it affects about 85% of cats over 6 years of age. (aaha.org)

The current standard of care is more rigorous than a quick oral look. AAHA’s 2019 Dental Care Guidelines say an awake exam can only provide a preliminary impression; accurate diagnosis and assessment require anesthesia, tooth-by-tooth probing, and full-mouth intraoral radiography. The organization also notes that many teeth that appear grossly normal have clinically important radiographic pathology, meaning disease severity can be underestimated without imaging. (aaha.org)

From there, treatment depends on stage and prognosis. For gingivitis, professional anesthetized cleaning and plaque removal may reverse inflammation. For periodontitis, options include closed periodontal treatment such as root planing and gingival curettage, open periodontal therapy with flap access, locally applied antimicrobials, and in selected cases regenerative procedures. But Merck Veterinary Manual is blunt that extraction is often the best treatment for teeth with increased mobility and attachment loss that carry a guarded to poor prognosis, and that pets can do very well afterward. AAHA similarly distinguishes prophylaxis in a healthy mouth from true periodontal therapy in a diseased one. (merckvetmanual.com)

Industry and expert commentary around the topic has been consistent rather than controversial. AAHA’s more recent dentistry coverage says the 2019 guidelines remain a cornerstone reference and recommends that small- and medium-breed dogs, along with all cats, receive their first anesthetized dental evaluation with full-mouth radiographs by 1 year of age. Cornell’s canine dental guidance also stresses that successful prevention depends on three things working together: veterinary assessment and treatment, a cooperative patient, and home care from the pet parent. (aaha.org)

Why it matters: For general practitioners, the review reinforces a practical point: periodontal disease management is a tooth-level decision, not a mouth-level label. That affects workflow, estimate design, and communication. A pet parent may come in expecting a “cleaning,” but the actual standard involves anesthesia, radiographs, charting, probing, and sometimes extractions or referral. It also supports stronger messaging against anesthesia-free dentistry; Merck states that cleaning an awake animal improves appearance but not periodontal health. (aaha.org)

There’s also a business and clinical quality angle. Earlier intervention may preserve more treatment options, while delayed care can narrow the path to extraction, especially in small-breed dogs, cats with concurrent tooth resorption, or cases with endodontic involvement. For practices, that means dental programs work best when they combine routine screening, clear staging, high-quality imaging, and realistic conversations with pet parents about prognosis, pain, and home care after treatment. (merckvetmanual.com)

What to watch: The likely next step isn’t a regulatory shift, but continued pressure toward earlier, more comprehensive dental workups in primary care, plus referral for advanced periodontal surgery only in carefully selected teeth where salvage offers a sound long-term prognosis. (aaha.org)
