One question I get occasionally is: how long shoul One question I get occasionally is: how long should you leave calcium hydroxide in the tooth—and do you wait for the periapical radiolucency to heal before obturation? The short answer is no. In most cases, calcium hydroxide should be left in the canal for about 2 to 4 weeks. At the second visit, if the canal is dry, there’s no drainage, and the patient is asymptomatic, you can move forward with obturation and the final restoration. Where I see confusion is the idea that you should wait until the radiolucency resolves before filling the tooth. The reality is that bone healing takes months, and with a two-dimensional periapical radiograph, you’re not going to appreciate that healing right away. In fact, the lesion may look unchanged even though healing is already happening at a histologic level. If you delay treatment just to “see healing,” you’re actually increasing the risk of recontamination by leaving a temporary restoration in place for too long. Or risk of fracture if a build up is placed but not the full coverage crown. Yes, CBCT can show healing earlier, but it’s not practical—or necessary—to scan every few weeks just to monitor progress. There are older studies where calcium hydroxide was repeatedly replaced until healing was seen, but we now understand that the healing comes from proper cleaning and disinfection of the canal system—not from leaving medicament in indefinitely. So clinically, once the canal is clean, dry, and the patient is comfortable, it’s appropriate to complete the case—and then monitor healing at your 6- and 12-month recalls. Docs—are you completing at the second visit, or still waiting for the PA to “look better” first? 👇🏽 #Endodontics #RootCanalTreatment #GeneralDentistry #DentalEducation #HowLongDoesARootCanalTake
We do this every single day 👇🏽 And still… the ques We do this every single day 👇🏽 And still… the questions keep coming: “Are root canals bad for you?” “How can I avoid a root canal?” “I heard root canals cause problems…” Let’s be clear—there’s a LOT of misinformation out there. ✨ Myths vs facts about root canals matter. Because what you’re seeing here isn’t theory… it’s real life. 🦷 Infections 🦷 Periapical pathology 🦷 Teeth that would otherwise be lost And the goal is simple: save the natural tooth whenever possible. Root canal treatment isn’t something to fear— it’s something that helps patients get out of pain and keep their teeth. So I’ll keep showing up. I’ll keep educating. And I’ll keep showing you exactly what we do every day behind the scenes. Because the more you see it… the more it makes sense. 📸 @mouthwatch — Docs—what’s the biggest myth your patients believe about root canals? 👇🏽

Owning a business—especially in dentistry—means yo Owning a business—especially in dentistry—means you’re never really “off.” 🖤 As a dentist, entrepreneur, and practice owner, my mind is always working: thinking about my team, my patients, treatment outcomes, payroll, marketing strategies, growth, and the next move. Even outside the office—at home, at dinner, or trying to unwind—you’re still building your practice, your brand, and your future. Because this isn’t just a job. It’s leadership. It’s responsibility. It’s risk. It’s vision. It’s legacy. And while the pressure is real… so is the purpose. ⭐⭐ #DentistLife #WomenInDentistry #EntrepreneurLife #PracticeOwner #DentalBusiness
