Silver Diamine Fluoride, a Tongue Plaque, and a 14-Resident Request
Danielle is an LDH with eight years of experience. She works four days a week in a suburban practice and one morning a month at a 60-unit assisted living facility under a written collaborative agreement with Dr. Reyes, whose office is 40 miles away. The agreement, signed 14 months ago, lists prophylaxis, fluoride varnish, sealant placement, oral cancer screening, and patient education, and says Dr. Reyes is reachable by phone during visits. Resident Mrs. K, 82, has not seen a dentist in three years. She has a fractured upper molar with exposed dentin and a 1 cm white plaque on the lateral border of her tongue that has been present about ten weeks. Her daughter asks Danielle to seal the broken tooth with the silver stuff and to just wiggle out the mobile fragment. The facility director asks Danielle to complete full-mouth scaling and root planing for 14 residents in a four-hour window without any dentist examination. Danielle holds a current license but no local anesthesia certification.
1. Which of the four requested activities - silver diamine fluoride, removing the fragment, scaling and root planing for 14 residents, and the oral cancer screening - may Danielle perform, and what must she verify first?

Authority comes from three layers, and all three must line up. First, the statute and board rules define dental hygiene services: prophylaxis, scaling and root planing, sealants, fluoride, and oral health screening and education are within the license; extracting a tooth or a tooth fragment is not, and no collaborative agreement can expand the statutory scope, so that request is refused outright. Second, the collaborative agreement defines which services may be provided without a dentist present and in which settings. Assisted living is an authorized setting, but silver diamine fluoride is not on the list, so she may not apply it until the agreement is amended and any required training is documented. Third, every patient still needs an individualized assessment and a referral plan. Screening is clearly permitted. Fourteen scaling and root planing appointments in four hours, with no examination, no radiographs, and no periodontal charting, is not defensible care at any supervision level; she should triage, treat what can be safely treated, and refer the rest.
2. What should Danielle do about the ten-week tongue plaque and the fractured molar, and how should that be documented and communicated?

A white plaque on the lateral tongue that has persisted for ten weeks is a red flag for a potentially malignant disorder and cannot be handled by watchful waiting or by a hygienist's reassurance. Danielle's role is recognition, documentation, and referral - not diagnosis. She should record location, size in millimeters, color, texture, whether it is fixed or mobile, whether it is painful, and how long the resident or family says it has been there; note tobacco and alcohol history; and photograph only with proper consent. She should arrange a dentist examination promptly and, because the resident has dementia, involve the daughter and the facility nurse so the appointment actually happens. The fractured molar with exposed dentin needs a dentist's diagnosis and treatment plan; she may place fluoride varnish if the agreement allows, but not silver diamine fluoride and not an extraction. The record should capture the referral date, the person contacted, and the follow-up plan, and she should check at the next visit whether the referral was completed.
3. The facility administrator asks whether the agreement can simply be updated to cover silver diamine fluoride and whether Dr. Reyes must examine every resident. What does Danielle explain about agreement content, review, and the dentist's role?

The agreement is not a formality; it is the legal basis for practicing without a dentist on site. It should be in writing, signed and dated by both parties, identify the practice settings and the specific services authorized, state how the dentist can be reached for consultation, and describe the referral and emergency plan for patients who need care beyond hygiene services. Silver diamine fluoride can be added only by amending the document and only if Danielle has completed whatever training the board requires for that service; she should also confirm the facility's standing orders permit it. The agreement must be reviewed and updated on the schedule the rules set and whenever either party's circumstances change. The dentist need not be on site and, in collaborative practice, need not examine every patient before a hygiene service, but the agreement must state how patients obtain a comprehensive examination and how findings are communicated. If the agreement lapses, Danielle has no collaborative authority and may only work where supervision is provided as the rules allow.
