Pediatric dentist finds joy in working with children

Bend, Oregon, Aug. 7, 2018 — Bluefish Dental & Orthodontics is delighted to announce pediatric dentist Dr. Sheala Lansden has joined our multi-disciplinary team. Dr. Sheala (pronounced “Shay-la”) received her Doctor of Dental Surgery (DDS) from Texas A&M University, College of Dentistry in 2014, where she recently completed additional training and education to obtain her board certification in pediatric dentistry.

“We are very happy to welcome Dr. Sheala to our Bluefish team,” said Bluefish founder Dr. Catherine Quas (Dr. Cate). “She has a strong work and community ethic and her experience plus passion for  pediatric dentistry align perfectly with our values and philosophy of care.”

Dr. Sheala is a native Texan, graduating valedictorian of her Palestine high school class. She received her bachelor of science degree in biomedical science with a minor in business from Texas A&M University, graduating Summa Cum Laude, Phi Beta Kappa and with a 4.0 GPA. As an undergraduate she was nominated for the Brown Foundation-Earl Rudder Memorial Outstanding Student Award. While studying for her DDS, Dr. Sheala also received multiple honors, including the Senior Student Award from the Texas Academy of General Dentists. She was a member of the Odontological Honor Society and the Dean’s List.

After receiving her DDS, Dr. Sheala worked in private practice for several years in Nacogdoches and Bullard, Texas. During this time she worked in both general and pediatric dental practices. Despite thriving, she felt called to specialize in pediatric dentistry.

“I realized that the times I found joy were when I was introducing my ‘water gun’ and singing songs with my kids in the chair. Not that the adult patients didn’t give me joy, but there is just something different about having a young mind that is so curious and open to new things and new advice,” said Dr. Sheala. “There was a voice inside me that told me pediatrics is where I needed to be. It is where I had always truly wanted to be. It is actually the reason I went to dental school.”

She still vividly recalls an incident that occurred ten years ago, while working as a substitute teacher at an elementary school: A student approached her with a request to visit the nurse, and when she asked why, he opened his mouth to reveal teeth that were severely decayed. Dr. Sheala made multiple attempts to find a local dental office that would accept the student as a patient, all of which were unsuccessful.

“It crushed my heart to have to return to school the next day knowing that I could not do anything to help this sweet boy,” said Dr. Sheala. “That was the moment I knew I wanted to be a pediatric dentist and got on track to work toward dental school.”

While working as a general dentist she began to feel that something was missing. After some serious soul-searching, she came to the conclusion that she was meant for pediatric dentistry.

After seeking counsel from colleagues and trusted peers, Dr. Sheala decided to apply for and was accepted to the pediatric dental residency program at Texas A&M.

“We are impressed with the passion that Dr. Sheala has for pediatric dentistry. She felt that she wanted more and she pursued her vision with courage,” said Dr. Cate. “And because of her past experience, she has the ability to look at and consider facets of adult dentistry that will benefit our growing patients in the future.”

Dr. Sheala is married to Dustin, and Kaison is their son.

Dr. Sheala, her husband, Dustin and their young son Kaison will be making their home in Redmond. Dustin is a native Oregonian, and the family is excited about establishing roots in Central Oregon. Dr. Sheala believes in giving back to the community, and she has a long history of volunteering for children’s and adult oral health initiatives. She looks forward to exploring and participating in volunteer opportunities in our region.

Athletic and adventurous, Dr. Sheala likes snorkeling, scuba diving, sky diving, snowboarding and running. She also enjoys reading and spending time with family and friends.

“We believe that Dr. Sheala is a great fit for Bluefish and our community,” said Dr. Cate. “She has a lovely, positive energy that brightens up a room and that people instinctively respond to. She’s intuitive and dedicated to continuing education, which aligns very closely with our practice philosophy. We admire her drive and passion for pediatric dentistry and we look forward to introducing her to our Bluefish families and the community.”

What the pediatric dentist says: Fluoride and your child

February 20th, 2014
A recent post on social media from a parent questioning the toxicity of fluoride prompted a detailed response from Dr. Cate.

A recent post on social media from a parent questioning the toxicity of fluoride prompted a detailed response from Dr. Cate.

A few days ago we shared a link via social media to a New York Times article regarding new guidelines from the American Dental Association recommending the use of fluoride toothpaste at an earlier age. One of our wonderful, bright and involved parents responded immediately, posting: “But fluoride is TOXIC! Or is that hippie propaganda?”

We love it when our families are engaged and asking important questions!  Here is what Dr. Catherine Quas posted in response:

“Great Question! Fluoride isn’t toxic except in extremely high doses and it isn’t hippie propaganda — I think that the answer to the question lies in the quality and quantity of fluoride. Fluoride, like many things, is beneficial in moderation. A little bit is good, a lot-a-bit is not better and can in fact be worse.

There are many sources of naturally occurring fluoride that make tracking the quantity of fluoride consumption difficult. For example, there are certain baby food formulas that add fluoride. If you then add in other sources of fluoride unknowingly, a young child can be exposed to excessive fluoride amounts. These amounts can be far from toxic but still produce tooth development challenges in the integrity of the tooth surface.

The maximum benefit of fluoride is in its topical (or surface acting) ability to strengthen the tooth surface. In essence it makes the tooth surface or enamel less able to be eroded by the acid produced by cavity causing bacteria.

In scientific lingo, fluoride lowers the dissolution Ph of enamel and renders the outside of the tooth more resistant to decay. The benefit of fluoride in toothpaste is that it is topical, much more consistent and very localized in application. People may forget vitamins, but tooth brushing is a highly consistent behavior across populations.

What is really nice in the article is that the ADA and the New York Times are differentiating in the size of the appropriate dose of fluoridated toothpaste. We used to routinely say “pea” size. That is way too much toothpaste for young children, particularly when we are advocating that the parents do a touch up course of brushing once the children are in their beds. A smear of toothpaste is a more appropriate representation of the minute amount necessary to provide the teeth with a protective benefit at night while we sleep.

It is important to remember that this is for kids who are not on systemic fluorides in drops or tablets. In fact, at Bluefish we do not advocate for systemic fluorides because the true benefit of fluoride is topical, meaning on the teeth not in the stomach.

The take home here is moderation. I encourage everyone to research the information with an open mind. Beware of the evangelical opinions on both ends of the fluoride spectrum. If at the end of the day, you are still uncomfortable with fluoride toothpaste, then I recommend that you understand thoroughly how cavities form so that you can take aggressive stances in other areas to reduce the risk of cavities. This could include eliminating juice, goldfish crackers, gummy bear vitamins, natural fruit roll ups, dried fruit, soda, vitamin water, etc. from the diet. It could include incorporating zylitol into the diet to combat the virulence of cavity creating bacteria.  Generally speaking, reducing fluoride tends to require an increase in effort on multiple levels. Not an impossible task, but it does necessitate a number of go-arounds.

I hoped I helped. Please know that I am always available for other questions — on or off Facebook.”

For those interested in learning more about fluoride, we recommend starting with a review of the ADA publication, Fluoridation Facts.  The booklet is in pdf format and includes more than 350 scientific references. Another great resource is this Guideline of Fluoride Therapy for parents and practitioners published by the American Academy of Pediatric Dentistry.

As always, everyone here at Bluefish Dental & Orthodontics welcomes your thoughtful questions and comments.
