The Dr. Phil Klein Dental Podcast

Are you still selecting composites based on shade count and marketing claims — or are you evaluating what actually matters clinically? This episode cuts through the noise and gets into the real science behind modern composite selection.
Dr. Mark Geissberger brings over 30 years of clinical and academic experience to this conversation. He is Professor and Immediate Past Chair of the Department of Integrated Reconstructive Dental Sciences at the University of the Pacific, School of Dentistry, where he directed the Aesthetic and Complex Care Clinic and has taught for 25 years. Dr. Geissberger earned his dental degree from University of the Pacific in 1991, was elected to Omicron Kappa Upsilon, and later earned a Master of Arts in Educational Psychology. He has served as President of the National Chapter of Omicron Kappa Upsilon, serves as University Representative to the AACD University Council, and has authored a textbook on esthetic dentistry published by Wiley-Blackwell. With over 350 continuing education programs presented nationally and internationally, Dr. Geissberger is one of the most experienced restorative dental educators in the country.
This episode explores how composite materials have genuinely evolved beyond marketing buzzwords, what dentists should actually evaluate when selecting a new restorative material, and how a new generation of universal composites is simplifying anterior and posterior workflows without sacrificing aesthetics. Dr. Geissberger provides a frank, science-based framework for evaluating handling, radiopacity, shrinkage, and shade matching that applies to any composite on the market. The conversation also covers composite warming, adhesive protocol selection, and isolation strategies for everyday clinical use.
Episode Highlights:
Single-shade composites made a bold promise that the science never fully supported. True shade matching requires cluster-engineered shade systems — a process that one leading manufacturer spent a decade developing to legitimately cover 16 Vita shades with just five carefully engineered shades, rather than simply repackaging existing best-selling SKUs.
Radiopacity is one of the most underappreciated criteria in composite selection. Measured in aluminum equivalent, conventional composites typically range from 300 to 500 percent, while dentin measures approximately 100 percent and enamel 200 to 250 percent. A highly filled universal composite can reach 900 percent aluminum equivalent, making restoration margins, recurrent decay, voids, and overhangs far easier to identify diagnostically on radiographs.
A composite filled at 91 percent by weight dramatically reduces polymerization shrinkage — down to approximately 1.4 percent compared to 2.2 percent or higher in conventional composites and 3 to 5 percent in flowables. Higher filler content also correlates with improved flexural strength, better wear characteristics, and a more sustained polish over time.
Composite warming — heating material to approximately 155 degrees Fahrenheit — serves two distinct clinical purposes: it improves handling by reducing viscosity for better adaptation, and basic chemistry supports that the added heat drives greater monomer conversion, depth of cure, and final hardness when the composite is cured within approximately two minutes of placement. This technique allows clinicians to adjust the same material's behavior differently for class five restorations versus anterior cases.
A universal adhesive used as a smart, substrate-driven etching strategy offers the most clinical flexibility. Total etch is appropriate for enamel-only preparations such as incisal edge repairs, selective etch suits combination restorations like class fives, and self-etch is preferable for root caries restorations. Over-etching dentin with total etch removes the mineralized substrate needed for effective bonding to the inorganic component of dentin and should be avoided in those situations.
Perfect for: General dentists looking to optimize their direct restorative workflow, dental residents building composite technique foundations, and restorative specialists evaluating new universal composite systems for anterior and posterior use.
If you place composite restorations in your practice, the clinical framework in this episode will change how you evaluate every new material that crosses your desk.

Are you leaving serious revenue on the table by treating your hygiene department as a break-even cost center? What if your hygienists could become the most powerful case acceptance drivers in your entire practice?
Katrina Klein is a registered dental hygienist with 17 years of clinical experience, national speaker, author, competitive bodybuilder, Certified Personal Trainer, Certified Ergonomic Assessment Specialist, and Functional Range Conditioning Mobility Specialist. She is the founder of ErgoFitLife, an organization dedicated to making ergonomics and fitness a lifestyle for dental professionals to prevent, reduce, or eliminate occupational pain. With nearly 30 years in dentistry and a reputation as a leading voice in dental hygiene advocacy, Katrina brings a uniquely evidence-informed, practice-centered perspective to expanding the hygiene role.
In this episode, Dr. Phil Klein and Katrina Klein challenge the widely held belief that the dental hygiene department is a loss leader, arguing instead that it can and should be a significant revenue-generating hub within any practice. The conversation covers how hygienists can move beyond scaling, root planing, and prophy to incorporate soft tissue laser therapy, adjunctive periodontal therapies, oral probiotic recommendations, airway assessment, implant maintenance, and orthodontic case co-diagnosis. They also address the current HR crisis in dental hygiene, the growing threat of DSO models utilizing minimally trained personnel for hygiene-adjacent procedures, and the critical importance of philosophical alignment between hygienists and practice owners. This discussion is essential for any dental team serious about elevating patient care and practice profitability simultaneously.
Episode Highlights:
A hygiene department focused solely on prophylaxis and scaling and root planing is unlikely to cover its own overhead at current wage rates. By incorporating comprehensive assessments, adjunctive periodontal therapies, airway screening, oral cancer screening, and co-diagnosis of restorative needs, hygienists can transform their operatory into a consistent revenue generator beyond insurance reimbursement ceilings.
A real-world case was presented in which a non-compliant periodontal patient was introduced to an adjunctive peroxide-based tray delivery system, resulting in reduced calculus burden, improved periodontal health, tooth whitening, and ultimately full patient buy-in for clear aligner therapy and soft tissue laser treatment at every maintenance visit — all within an insurance-based practice.
Soft tissue laser therapy is identified as one of the highest-impact tools available to hygienists, yet lasers frequently sit unused in practices because hygienists lack hands-on training and confidence. Sending the hygiene team together to live, hands-on continuing education courses — rather than passive lecture-format CE — is recommended as the most effective strategy for clinical adoption and team-wide implementation.
Peri-implantitis is described as a growing clinical priority, with hygienists now encountering implant patients at nearly every maintenance appointment in periodontal-focused practices. Updated protocols have replaced outdated instrumentation approaches, and ongoing continuing education is emphasized as essential for hygienists to confidently probe, assess, and educate implant patients on proper home care.
A legislative trend is emerging in multiple states allowing dental assistants with as few as 120 hours of training to perform supragingival scaling under DSO models, creating a direct workforce and quality-of-care challenge for registered dental hygienists. Hygienists are encouraged to proactively demonstrate their expanded clinical value, advocate for their scope of practice, and educate patients on the meaningful difference between credentialed hygiene care and minimally trained scaling services.
Perfect for: Dental hygienists at all career stages looking to expand their clinical role and earning potential, general dentists and practice owners evaluating hygiene department productivity, and dental residents or new graduates building their philosophy around comprehensive team-based care.
If you have ever wondered whether your hygiene department is working as hard as it could for your patients and your practice, this episode will completely reframe how you think about it.

How confident are you that the white patch you noticed at your last exam wasn't something that needed a biopsy? The uncomfortable truth is that for every HPV-negative oral cancer, there was a visible precancerous lesion — and fewer than 5% of those lesions are identified before they become cancer.
Dr. Ashley Clark is an Associate Professor and Division Chief of Oral Pathology at the University of Kentucky College of Dentistry. She holds a DDS from Indiana University and a certificate in Oral and Maxillofacial Pathology from the University of Florida. With over 40 published papers and abstracts, more than 200 continuing education courses delivered, a Fellowship in the American College of Dentists, a Fellowship in Health Education, and authorship of the oral pathology sections of both Dental Decks and Dental Hygiene Decks, Dr. Clark is one of the most prolific oral pathology educators in the country. She has earned multiple prestigious teaching awards, serves on the Commission on Dental Accreditation review board for oral and maxillofacial pathology programs, and sits on the Advisory Board for Oral Cancer Cause.
In this episode, Dr. Clark breaks down the full spectrum of oral potentially malignant disorders (PMDs) — from leukoplakia and erythroplakia to erosive oral lichen planus and proliferative verrucous leukoplakia — and explains exactly why the dental profession is failing to intervene early enough. The conversation covers the clinical criteria that demand a biopsy with no exceptions, why the standard two-week watch-and-wait approach is inappropriate for sharply demarcated lesions, and how to structure long-term surveillance once a PMD is diagnosed. Dr. Clark also addresses the medicolegal exposure dentists face when PMDs go unmonitored, and makes a clear, evidence-based case that appropriately treating leukoplakia alone could reduce oral cancer rates by 50%.
A sharply demarcated white lesion requires a biopsy regardless of patient history, smoking status, or lesion duration — no additional clinical information changes this decision. Watching such a lesion without a diagnosis is not a valid clinical strategy because it is impossible to treat something without knowing what it is, and the most common benign diagnosis is hyperkeratosis while the most common malignant result is squamous cell carcinoma.
Autofluorescence devices can serve as a useful adjunct to white-light examination, but should not be used as standalone diagnostic tools. If a lesion loses fluorescence compared to surrounding healthy tissue, the clinician should return to white-light examination to determine whether the area is sharply demarcated — if it is, biopsy is indicated regardless of other findings.
Once a PMD is diagnosed and treated, the standard of care supported by the literature requires monitoring every six months for 20 years, with each visit including photographic documentation and probe measurement of the lesion. Any change in size, surface character, or appearance at a surveillance visit warrants a new biopsy; if the lesion remains stable, continued observation without repeat biopsy is appropriate.
When dysplasia is confirmed histologically, the recommended treatment escalates based on severity: mild dysplasia may be managed with laser ablation, while moderate dysplasia, severe dysplasia, or carcinoma in situ warrants surgical excision with a scalpel. After tissue destruction, the patient returns to the general dental office for long-term surveillance monitoring for recurrence or new sites of involvement.
General dentists are technically capable of performing punch biopsies on accessible sites including attached gingiva, buccal mucosa, lateral tongue, dorsal tongue, labial mucosa, and hard palate. Sites including the floor of mouth, ventral tongue, soft palate, and gingival bumps with aesthetic considerations are better referred to oral surgery or periodontics; post-operative management of punch biopsy sites typically requires pressure hemostasis, chemical cauterization if needed, and a single suture for tongue sites, with minimal analgesic requirements for most patients.
Perfect for: General dentists seeking clearer biopsy decision-making criteria, dental hygienists who perform oral cancer screenings, dental residents in any specialty, and practice owners who want to understand the medicolegal implications of PMD surveillance protocols.
If you've ever hesitated before recommending a biopsy, this episode will give you the clinical framework and the conviction to act.

Are you pouring money into dental marketing every month without knowing if it's actually working — or worse, overpaying for services that underperform?
Brandon Bosch is the President and Founder of Dr. Marketing, a dental-specific marketing agency with clients across the USA, Canada, Central America, and beyond. A Certified Marketing Expert in both Google and Meta advertising, Brandon has been working exclusively in the dental industry since 2008. He has led the development of hundreds of high-performing dental websites and advertising campaigns, and is a sought-after speaker at major dental conferences including New York, Chicago, Anaheim, Florida, and Hinman. His expertise spans digital advertising strategy, search engine optimization, print marketing, lead tracking, and the psychology of patient acquisition — all within the highly regulated dental landscape.
This episode cuts straight to the real-world marketing challenges dental practice owners face, from overpaying for generic services to navigating the patient flow disruptions that come with dropping an insurance plan or acquiring an existing practice. Brandon brings concrete benchmarks, actionable frameworks, and case studies drawn from years of working exclusively in the dental space. Whether you are trying to attract high-value fee-for-service patients, rebuild after a transition, or simply understand what you should actually be paying for marketing, this conversation provides the clarity and structure most dental owners are missing.
Episode Highlights:
Most dental practices have no reliable system for tracking whether their marketing investment is actually converting into new patients. Without a lead-tracking layer between your website and your patient management system, you are forced to rely solely on reception staff feedback — creating a three-way disconnect between the practice owner, the front desk, and the marketing agency that is difficult to resolve objectively.
The industry benchmarks for patient acquisition costs range from approximately $150 for emergency and hygiene-driven patients up to $450 for cosmetic, implant, and orthodontic cases. On average, a dental practice can expect to convert approximately 40% of inbound leads into confirmed appointments, meaning a pipeline of 50 leads typically yields around 20 new patients.
Practices offering promotional discounts to attract new patients should be aware that the recall rate for discount-driven patients runs between 30 and 40 percent. This self-selects for low-retention patients and actively works against long-term practice growth, making discount-based campaigns a poor investment for PPO or fee-for-service offices.
When a practice drops a major insurance plan, a significant short-term revenue decline is expected. One documented case saw monthly collections fall from approximately $85,000–$89,000 down to $65,000 before recovering to near $80,000 over a 14-to-15-month period. A strategic shift in marketing messaging — emphasizing second opinions, in-house membership plans, and third-party financing options — is essential to attracting fee-for-service patients and closing larger cases during the transition.
Short-term marketing strategies such as paid search ads, meta ads, and print campaigns generate immediate lead flow but require ongoing spend, while long-term strategies such as search engine optimization, blog content, and directory management build compounding organic traffic over time. A well-structured marketing plan uses both in combination, tailored to the specific goals and growth stage of the practice — and should be reviewed jointly by the practice owner and office manager at least once per month.
Perfect for: General dentists, practice owners considering or currently transitioning away from insurance, dental office managers, treatment coordinators, and any dental professional who wants to evaluate or improve the ROI of their current marketing investment.
If you have ever wondered whether your marketing dollars are actually growing your practice or just keeping a vendor in business, this episode will give you the frameworks to find out.

What if your dental chair is actually one of the most powerful wellness intervention points in a patient's entire healthcare journey? Most dental professionals spend more face time with their patients each year than any other clinician — yet too many are leaving that opportunity completely untapped.
Dr. Uche Odiatu, DMD, is a practicing dentist in Toronto, author of The Miracle of Health and Fit for the Love of It, and a professional member of the American College of Sports Medicine. He holds certifications as an NSCA Certified Personal Trainer, Certified Yoga Instructor, and Certified Boot Camp Instructor, and has delivered over 500 lectures across the United States, Canada, England, Denmark, Norway, Bermuda, and the Bahamas. He has presented at the American Dental Association Annual Session 14 times since 2006, making him one of the most recognized voices in dental wellness education.
In this episode, Dr. Odiatu and Dr. Phil Klein explore the mind-body-mouth connection and make a compelling case for why conversations about sleep, nutrition, obesity, stress, and exercise belong in the dental operatory. Drawing on current research in neuroscience, exercise science, gastroenterology, and sleep medicine, Dr. Odiatu offers a framework for how dental professionals can deliver high-impact wellness guidance in as little as 30 to 45 seconds chairside. The discussion reframes dental practice from a transactional model focused on procedures to a transformational model centered on patient health outcomes.
Episode Highlights:
Brain-derived neurotrophic factor (BDNF) is elevated through regular physical exercise and plays a direct role in neuroplasticity and learning. This connection between movement and cognitive performance — intuited decades ago and now confirmed by neuroscience and psychiatry — forms the foundation of the mind-body-mouth framework discussed throughout the episode.
A 2024 Journal of Obesity study found that over 90% of dental patients reported they would be comfortable having their dental provider discuss nutrition, weight management, and obesity chairside. Research also shows that obese patients — independent of smoking status and oral hygiene — demonstrate significantly greater loss of attachment, increased bleeding on probing, and tooth mobility, making weight a clinically relevant conversation in the periodontal assessment.
Sleep quality is framed as a critical systemic health indicator that dentists are uniquely positioned to address. Patients presenting with daytime drowsiness, dry mouth, or morning headaches may benefit from referral for a formal sleep study, which can reveal not only apnea events but also deep sleep duration, blood pressure variability, and nocturnal hypoglycemic episodes — all factors that affect healing and overall systemic health.
Approximately 95% of adults consume insufficient dietary fiber, averaging around 12 grams per day against a recommended minimum of 30 grams. Adequate fiber intake — both soluble and insoluble — supports the gut microbiome's production of short-chain fatty acids, which function as endogenous anti-inflammatories. Given that periodontitis, gingivitis, and most systemic diseases share an inflammatory pathophysiology, this has direct clinical relevance to the dental patient population.
Power toothbrushes and water flossing devices represent a significant upgrade over manual oral hygiene tools, with powered brushing cited as dramatically more effective than manual brushing. For patients with implants, limited dexterity, or documented poor flossing compliance — estimated at approximately 95% of patients — chairside demonstration of proper water flosser technique, including lip seal around the tip, can dramatically improve home care adherence and protect restorative work.
Perfect for: General dentists, dental hygienists, and specialists looking to expand their clinical impact beyond the oral cavity — particularly those interested in integrating wellness conversations into recall exams, new patient appointments, and restorative consultations without adding significant chair time.
If you've ever wondered how to make your practice feel more meaningful while delivering measurably better patient outcomes, this episode gives you the science, the scripts, and the confidence to start tomorrow.
