Find a Periodontics Expert →Overview
A periodontics expert decides whether gum disease was present, whether it should have been found, and whether the treatment built on those teeth was sound. Most of these claims are not about a periodontist at all. They arise when a general dentist or implant provider placed crowns, bridges or implants on a mouth with active disease, or when years of cleanings went by with no one measuring the pockets. This page covers gums, bone and implants as a matter of periodontal care. Root canal treatment belongs to an endodontics expert, general restorative care to a dentistry expert, and jaw surgery to an oral and maxillofacial surgeon.
The expert reads the dental chart, periodontal charting over time, radiographs in native digital form, hygiene notes, treatment plans, implant records, referral letters and consent forms. A run of full-mouth probing charts is the most valuable record, and its absence is often the first finding.
NIDCR describes periodontal disease as an infection causing inflammation of the tissues that hold the teeth in place 1. It starts with swollen, red and bleeding gums, can spread to the bones supporting the teeth, and in the worst cases teeth may become loose or need to be removed 1. Examination is straightforward: the dentist looks for inflammation and bleeding and uses a probe to measure the pockets around the teeth, and in advanced disease the supporting bone is destroyed 1.
That simplicity is why missed disease is hard to defend. If charts show bleeding and bone loss on films year after year with no probing, no diagnosis and no referral, the record is hard to explain. The defense often points to the patient: missed recalls, poor home care, smoking or diabetes. CDC lists risk factors that include malocclusion, clenching and grinding 2, so a careful expert sorts which factors applied, what was known and what the patient was told.
The fullest published picture comes from Israel, where a study reviewed 508 legal claims related to periodontal disease closed between 2005 and 2019. Most claims, 82.8 percent, settled out of court 3. Only 4.5 percent concerned treatment of periodontal disease by periodontists, while 95.5 percent were complications secondary to another treatment 3. Prosthodontic treatment was involved most often at 54.5 percent, followed by dental implants at 17.7 percent and endodontics at 11.6 percent 3. The most common allegations were pain and distress, aggravation of existing periodontal disease and tooth loss, and 47 percent alleged a violation of autonomy 3. Legal systems differ, so those numbers do not transfer directly to any United States forum, but the pattern is familiar: the fight is over what was built on an unhealthy foundation.
Implant cases are often about planning and maintenance. FDA describes an implant system as an implant body surgically inserted in the jawbone in place of the tooth's root 4. The expert asks whether the bone and gum condition supported placement, whether disease was controlled first, whether imaging was adequate and whether the patient kept up with care afterward. Peri-implant infection and bone loss can look like a surgical failure when they are really a maintenance problem, or the reverse. Grafting and sinus lift procedures raise similar questions about case selection and follow-up.
NIDCR says treatment may involve scaling and root planing, a deep cleaning, and that advanced cases may require surgery 1. The standard asks for a reasonable response to what was found. Disputes turn on whether a general dentist kept treating a case that should have gone to a specialist, whether the patient was told the disease existed and whether refusal of a referral was documented. Orthodontic treatment on periodontally involved teeth raises its own issues: an Israeli study of 35 such claims listed periodontal disease or aggravation in 97 percent of them 5.
Consent matters here, too. A patient who was never told about bone loss before an expensive bridge was placed has a different case from one who chose to go ahead knowing the risk.
Look for a licensed dentist with specialty training in periodontics, active practice at the time of the events and board certification where held. The American Board of Periodontology certifies in periodontology and dental implant surgery 6. If the defendant is a general dentist, state law may call for an expert in that same field, so counsel should check whether a periodontist can give the standard of care opinion or should be paired with a general dentist.
In a study of 508 Israeli periodontal claims, 95.5 percent were complications secondary to another treatment, and only 4.5 percent concerned treatment by periodontists.

FAQ
Look for a licensed dentist with specialty training in periodontics and active practice at the time of the events, with board certification where held. If the defendant is a general dentist, state law may call for an expert from that field.
Yes, if the standard called for it and harm followed. The expert reads probing charts, radiographs and hygiene notes over time, and asks what should have been found, what the patient was told and whether a referral was due.
In a study of 508 Israeli claims, 95.5 percent were complications secondary to another treatment, most often prosthodontic work. Only 4.5 percent concerned treatment by periodontists. Other legal systems may differ.
It depends on the facts. Planning, surgery, gum and bone condition, and maintenance can each contribute. An expert reads imaging and maintenance records to separate them.
Not automatically. Missed recalls, smoking and poor home care may reduce or defeat a claim depending on state law. The expert looks at what the patient was told and what the record shows was done about it.
In general, periodontics expert fees are determined by the expert themselves, based on a variety of criteria. Among those criteria are experience, the length of the treatment history, the number of images, implant issues and the amount of testimony. Vident does have some influence over expert fees by comparing experts within a specialty, but ultimately it is a personal decision by the expert.
