Lead found in major toothpaste brands

The doctor and his dog can be a powerful dental duo. This week, we talk to a dentist whose family dog has become an important part of his practice. We also dig into a new report on the amount of lead and other heavy metals present in most leading brands of toothpaste. But first, stop to smell the flowers; a dentist in Holland, Mich., is showing off a rare (and smelly) tropical bloom.

The fluoride fight continues. Following Robert F. Kennedy Jr.'s vocal opposition to fluoride, many experts in dentistry are speaking out. Experts argue that fluoride has been a major win for public health, saving billions in treatment costs.

A dental practice hack. Community Dental Care, a nonprofit Medicaid practice in Minnesota, discovered a breach of its computer system back in December. The practice is notifying nearly 135,000 of its patients that their personal information was potentially compromised in the breach.

Trends in standalone dental insurance. In a Q&A with BenefitsPRO, Sam Melamed, CEO of dental and health insurance company NCD, talks about the regulatory forces driving change in the standalone dental insurance market.

Patient financing and case acceptance. Financing options can help many patients access the dental care they need, but confusion can get in the way, going from treatment planning and financing proposal to case acceptance. An episode of the "Everyday Practices Dental Podcast" dives into the patient experience and what practices can do to improve their case acceptance rate.

Cancer and the oral microbiome. Scientists continue to learn more about the oral microbiome and how it affects overall health. Oral microbiota, for example, play a role in the development of tumors. More research could lead to a better understanding of the oral microbiome's role in cancer and better patient outcomes.

'Dogs bring love and joy wherever they go'

Dogs have a long history of providing comfort to their human companions. That skill could be a big benefit for people who associate a trip to the dentist with feelings of trepidation and anxiety.

Ed Wiggins, DDS, first brought his family's goldendoodle, Ruby, into the office to keep an eye on her. But soon Ruby became a member of the team. She calmly greets patients, and many of them request she be there for their appointments.

How did Ruby first come into your life? How did you decide to start bringing her into the office?

Like a lot of people getting bored during the pandemic, we got our pandemic puppy, Ruby, in late summer 2020. Our kids were 7 at the time, and they begged for a puppy. The old story of "Yeah, it will be our dog" and all that.

I wasn’t ready for another dog as my beloved Bruce had passed about a year prior, but my wife encouraged it, and the kids begged enough to make it happen. We decided on a golden retriever poodle mix as we like the look of them, but they are also hypoallergenic and don't shed as much as a pure golden. I wanted a smaller version, but my wife found her, and once kids see a puppy, it’s hard to say no. We got Ruby when she was 3 to 4 months old. She was a real terror as a puppy. Hard to house train and loved to bite and eat everything and everyone, but eventually she came into her own and became a reasonable home companion.

Did Ruby require any specific training to fill her role as an emotional support dog?

I decided to bring her into the office out of what felt like necessity. Fast forward to Ruby as a 4-year-old when the kids were starting back to school. I didn’t have anyone to hang out with Ruby. Sacramento is too hot to leave her outside all day. My wife travels a lot for work. And so I took a chance to see how she would do in the office for a day.

I was pleasantly surprised. There was a light switch that went off in her head. She knew I was trusting her with something important, I could sense. Within my practice, she became way more mellow and careful. Her tail didn’t even wag with such ferocity as it normally would. She instinctively knew not to go into the actual operatories without an invitation. She calmly greets each patient, gets a few pets in, then comes to my office. And this is all without any specific training. Somehow, she just knows what to do.

How did you and your staff prepare initially to introduce her to patients? What kind of protocols are in place for staff responsibilities for Ruby and patient interaction?

My team doesn’t need to do anything really. We have a sign at the front desk introducing her, and it says if the patient is uncomfortable with her for any reason, she can have a nap in my office and close the door. Only maybe once or twice has it been an issue, more with a patient who was attacked by a dog as a child.

Every now and again, if my procedure is going through lunch for some reason, I’ll have someone walk her around the block. But mostly she’s fine until lunch, and we go on a nice walk so she can chase some squirrels around.

What are the benefits of having Ruby in the office? What kind of response have you seen from patients?

The benefits to the office, I think, are pretty profound. She takes the edge off our team and anxious patients. She’s been really well received by patients, with many requesting she be there for their appointments. If we are running behind, she gives patients a little entertainment by bringing them her favorite stuffed animal. After appointments are done, she can’t wait to see her new friend and patients as if to say congratulations!

Dogs bring love and joy wherever they go and my dental office is no different. It’s also great for dogs. They love being helpful and around people. I think it gives them purpose and makes them happier.

Do you have any advice for other dental practices considering adding a dog to their team?

This one’s tough because I only have experience with my own dog. The signage is important so patients know they have a choice in their level of interaction.

Have a special spot for the dog to go to. For us, it’s a little nook oin my office. Dogs like to have a cave-like area to be able to retreat to. Bring your dog to an office meeting first to see how the dog responds while there are no patients there. Have time set aside in the day to get out of the office for half an hour. Get stylish food and water bowls that fit your decor. Make sure your dog is not a safety risk for patients, themselves or team members. Encourage behavior through treats. After Ruby greets a patient, if I’m around, she gets a treat.

Lead in major toothpaste brands

Lead Safe Mama tests consumer goods for heavy metals. The organization recently reported the results of testing conducted on 51 brands of toothpaste. It found that 90% of those brands contained lead and 65% had arsenic. Mercury and cadmium were also detected in several toothpaste brands. Tamara Rubin, the founder of Lead Safe Mama, reported that no brands have shared plans to remove the lead from their toothpastes.

Why it matters: While heavy metals are toxic, there are debates on levels requiring concern. The levels that Lead Safe Mama detected in the toothpaste did not exceed federal limits, but they did exceed some state limits. (The Guardian)

Rethinking TMJ

In a recent article for Dentistry IQ, Gene McCoy, DDS, an honored fellow with the American Academy of Implant Dentistry, discusses an overlooked cause of TMJ disorders. While grinding has historically been the main focus of treatment, Dr. McCoy urges the dental profession to look at dental compression syndrome (DCS). DCS has unique signs and symptoms that patients may not recognize.

Why it matters: Millions of people live with TMJ disorders. Considering how DCS could help dentists talk to their patients about TMJ and manage it. (Dentistry IQ)

The ethics of AI in dentistry

AI applications are only growing in dentistry. Researchers conducted a web-based survey to understand how dentists view this new technology and its ethical use. While AI can be a beneficial tool for diagnostics, treatment planning and administrative work, dentists also acknowledge that it requires human oversight, and safeguards are needed to ensure patient information is not compromised and clinical judgment is not influenced.

Why it matters: Dentists have a responsibility to consider any ethical challenges this technology comes with as they find ways to adopt it in their practices. (Cureus)
