Standing Orders and a Loose Tooth in Assisted Living
Priya R., RDH, provides hygiene care under contract at a 120-bed assisted living facility in Montgomery County. Eleven months ago the contracting dentist examined every resident on site and wrote standing orders: 'prophylaxis and fluoride every six months; notify me of any change.' Today Priya sees Mr. H., 78, whose chart lists hypertension, atrial fibrillation, and type 2 diabetes. The nurse reports his A1c is now 10.2, he started warfarin six weeks ago (INR drawn two days ago: 3.4), and his gums bleed when he brushes. On examination, the gingiva around tooth #12 is violaceous, the tooth is mobile to 5 mm with a 9 mm pocket, and he has had no fever. The standing order carries no expiration date, the dentist is 45 miles away in an operating room and cannot come today, and the facility administrator asks Priya to 'clean everything and take care of that loose tooth' before tomorrow's state survey.
1. May Priya complete the prophylaxis and fluoride application today under the standing order? Identify the regulatory and clinical conditions she must satisfy, and state what she should do about tooth #12.

Framework. In Maryland, hygiene care is delivered under a dentist's supervision, and the permission category plus its conditions come from the Dental Practice Act (Health Occupations Article, Title 4) and COMAR 10.44. General supervision allows treatment when the dentist is not on the premises, but only where the patient has been examined and the treatment authorized within the interval the regulation requires, and where the patient's condition has not materially changed.
Apply it.
- An 11-month-old 'standing order' with no expiration date and no patient-specific authorization is the weak link. Before treatment, Priya needs written confirmation that the dentist's authorization is current for Mr. H. If the applicable rule requires a dentist examination within an interval shorter than 11 months, she cannot treat under general supervision; the dentist must examine or document a compliant authorization first.
- The clinical picture has changed. INR 3.4 on warfarin, new 5-mm mobility, and 9-mm pocketing are not a routine recall. Aggressive subgingival instrumentation in an anticoagulated patient, and manipulation of an acutely mobile, possibly abscessed tooth, is a dentist-level decision. Notify the dentist and arrange urgent evaluation before any instrument goes below the gingival margin.
- Fluoride application and atraumatic supragingival polishing are the lowest-risk components, but even these should not be delivered if the dentist has not authorized care for this patient or if an acute infection requires referral.
Bottom line. No blanket 'clean everything.' Obtain a current, documented authorization, modify the treatment plan, and escalate #12 to the dentist the same day.
2. The administrator says: 'Just take care of that loose tooth - the surveyors are coming.' Draft the response Priya should give and the actions she should take.

What she may not do. Extraction is not within a dental hygienist's scope at any supervision level; it is surgery on hard and soft tissue reserved to the dentist. 'Taking care of' a 5-mm-mobile tooth could also mean scaling it, which is contraindicated here without a dentist's examination and medical clearance.
What she should say. Be plain, not apologetic: 'I'm a licensed hygienist. I can clean and apply fluoride once the dentist has authorized it for this patient, but I cannot extract or treat a mobile tooth. With an INR of 3.4 and new mobility, he needs the dentist today.' Do not imply she will 'see what she can do.'
Actions, in order.
- Call the dentist directly, not through the standing order; record the time, who was reached, and the instructions received.
- If the dentist cannot come, ask for a specific plan: referral to the facility's medical director, a community dental clinic, or a hospital dental service, plus whether the physician should be notified about bleeding risk on warfarin.
- Put the administrator's request and Priya's refusal in a contemporaneous note.
- If the tooth is avulsed or bleeding heavily: firm pressure, contact the dentist and the patient's physician, and arrange emergency care.
Reframe the pressure. A survey finding is not a clinical indication. A note reading 'mobile #12 identified today; dentist notified 10:20; urgent referral arranged' both protects the patient and gives surveyors better documentation than an out-of-scope extraction ever would.
3. What should Priya document, and what should she fix about the practice's arrangement with the facility before the next visit?

Chart entry (facts, times, names).
- Medical update received: A1c 10.2, warfarin started six weeks ago, INR 3.4 drawn two days prior, source of information named.
- Clinical findings: mobility grade, probing depth at #12, tissue description, absence of fever.
- Services actually delivered and services withheld, with the reason for each.
- Communication: dentist contacted at [time], by [method], instructions received; referral made to [who], appointment date.
- The administrator's request and the hygienist's refusal, stated neutrally.
- Patient education given (anticoagulation and bleeding, urgency of evaluation).
System fix. The standing order cannot keep functioning as a substitute for per-patient authorization. Priya should ask the dentist to put in writing: which patients are currently authorized, the date of each authorizing examination, the recall interval, the process for changes in medical status, and how the dentist will be reached when he is unreachable. She should also confirm the facility's expectations in writing so that non-clinical staff do not treat the hygienist as the on-site dentist.
Do not do. Do not write 'care deferred at patient request' if the real reason was lack of authorization. Do not backdate an authorization or sign as if the dentist had examined the patient that day. Both would convert a scope problem into a falsification problem.
