Experts Caution About Rising Trend: Dentists Extracting Healthy Teeth to Advocate Costly Implants

# The Surge of Dental Implants: Are They Always Essential?

Recently, dental implants have gained traction as a favored option for those aiming to substitute lost or damaged teeth. The promise of achieving a flawless smile, often touted by establishments such as ClearChoice Dental Implant Centers, has persuaded numerous patients to choose implants, sometimes sacrificing the preservation of their natural teeth. Yet, as the sector expands, so do worries regarding the excessive application of implants and the associated risks.

## The Attraction of Dental Implants

Having been in use for over 50 years, dental implants provide a means for patients to replace missing or damaged teeth with artificial counterparts. The procedure generally requires the placement of a titanium post into the jawbone, serving as a root for a prosthetic tooth or crown. For those facing significant tooth loss or damage, implants can transform lives, reinstating not only their chewing ability but also their self-esteem.

Companies like ClearChoice have seized this opportunity, marketing their ability to deliver a “new smile in as little as one day.” For individuals such as Becky Carroll, who felt self-conscious about her discolored and misaligned teeth, the appeal of a swift and lasting remedy was compelling. Carroll, similar to many others, chose full-arch implants, substituting all her upper teeth with prosthetic versions.

Unfortunately, Carroll’s experience diverged significantly from the outcome she envisioned. In a legal action, she claimed that her anesthesia faded during the procedure, leaving her aware as screws were inserted into her jaw. Moreover, her prosthetic teeth were so misaligned that she struggled to chew properly for over two years. Carroll’s case is not isolated, as numerous lawsuits nationwide have unveiled parallel issues and apprehensions.

## The Expanding Industry and Associated Concerns

The dental implant sector has experienced swift expansion, with over 3.7 million implants sold in the U.S. in 2022 alone. Countless dental practitioners now provide the surgery, and private equity firms have poured billions into dental chains that focus on implants. However, amidst this surge, some professionals are sounding the alarm regarding the overreliance on implants and unnecessary extractions.

A lengthy investigation by KFF Health News and CBS News uncovered that many dentists might be hasty in suggesting implants, even when it’s feasible to save natural teeth. In discussions, 10 dental experts shared worries that some dentists preferred implants over more conservative options like root canals or crowns. These experts cautioned that unnecessary tooth removals put patients at risk of surgery complications and future dental issues.

William Giannobile, dean of the Harvard School of Dental Medicine, pointed out that numerous dentists are driven by the financial incentives tied to implants, which can yield more profit than conventional dental care. “It pains me to say this, but many are pursuing it because these procedures are, in monetary terms, far more advantageous to the practitioner,” Giannobile stated.

## The Hazards of Implants

While implants can yield remarkable results, they come with inherent risks. Unlike natural teeth, implants can be prone to infections in the gums and bone, necessitating ongoing upkeep. George Mandelaris, a periodontist and member of the American Academy of Periodontology Board of Trustees, warned that when implants fail, they may deteriorate significantly faster than natural teeth.

“If an implant faces infection, or if there is bone loss, an implant can fail much more rapidly than teeth can,” Mandelaris elaborated.

Furthermore, full-arch implants, which replace all teeth in either the upper or lower jaw, may pose unique challenges if they fail. Patients may find themselves without sufficient jawbone to support additional implants, leaving them with limited treatment options.

## The Influence of Private Equity in Implant Dentistry

The influx of private equity investments in dental chains has further muddied the waters of implant dentistry. Private equity firms have acquired large dental organizations such as ClearChoice, Aspen Dental, and Affordable Care, which now oversee numerous clinics nationwide. While these companies assert that clinical decisions are made by dentists rather than investors, some experts express concern that profit maximization pressures could result in overtreatment.

Edwin Zinman, a dental malpractice lawyer and former periodontist, contended that private equity ownership has caused a rise in unnecessary and poorly performed implant surgeries. “They’ve sold numerous

“Boeing mum on Starliner’s prospects almost two months post its comeback”

# Boeing’s Starliner: A Future in Uncertainty?

Boeing’s Starliner spacecraft, once celebrated as an essential component of NASA’s commercial crew initiative, finds itself at a pivotal moment. Following its momentous first human spaceflight earlier this year, the spacecraft touched down in the New Mexico desert, but not with its crew aboard. Astronauts Butch Wilmore and Suni Williams are still on the International Space Station (ISS), waiting for their ride back on SpaceX’s Crew Dragon. In spite of this accomplishment, Boeing has been remarkably reticent about the future of Starliner, prompting many to ask: What lies ahead for the spacecraft?

## An Empty Triumph

The Starliner’s re-entry to Earth signified a notable success for Boeing, yet it was also a tinge of sorrow. While the spacecraft accomplished its objective, the lack of Boeing representatives at the post-landing press conference raised eyebrows. Expected attendees like John Shannon, Boeing’s head of human spaceflight, and other top officials were nowhere to be found. Instead, Boeing released a concise statement from Mark Nappi, vice president and program manager of Boeing’s commercial crew initiative, announcing that the company plans to “analyze the data and chart the next course for the program.”

Since that moment, Boeing has continued to be tight-lipped, giving scant information about Starliner’s outlook. Inquiries for comments have gone unacknowledged, increasing speculation regarding the spacecraft’s future. This reticence coincides with Boeing grappling with severe financial difficulties, having already reported losses of $1.85 billion linked to the Starliner program.

## The Economic Burden

Boeing’s financial predicaments regarding Starliner are widely known. The company has been losing substantial amounts on the program, and its new CEO, Kelly Ortberg, has suggested that adjustments could be forthcoming. During a recent quarterly earnings conference, Ortberg indicated that Boeing is scrutinizing its various business segments, including Starliner, to assess what should be retained and what might be divested.

This review is taking place amid indications that Boeing may contemplate divesting some of its space ventures, including Starliner. The Wall Street Journal recently unveiled that Boeing is exploring the prospect of selling its space division, potentially encompassing the Starliner program. If Boeing can recapture some of its investments, it may be inclined to take the financial hit and depart from the commercial crew arena.

## NASA’s Involvement in Starliner’s Prospects

As Boeing struggles with its financial issues, NASA also holds a stake in Starliner’s future. The agency has long championed the necessity of having two crew transport systems to the ISS, with SpaceX’s Crew Dragon as the primary option. Nonetheless, NASA may find it necessary to intervene to assist Boeing in alleviating some costs associated with certifying Starliner for operational crew missions.

One possible approach is for NASA to compensate Boeing for conducting a cargo mission to the ISS. This could permit Boeing to test repairs to its propulsion system and resolve problems linked to its helium pressurization system. A successful uncrewed cargo flight could facilitate Starliner’s certification for crewed missions. Indeed, NASA has already solicited its space station program for potential timeframes when the ISS could accommodate a cargo-only Starliner mission in the next 18 months, eyeing possible opportunities in June 2026, January 2026, and March 2026.

However, there’s a caveat: NASA doesn’t inherently require additional cargo services. Sierra Space’s Dream Chaser vehicle is anticipated to commence cargo operations to the ISS within the following year, possibly diminishing the demand for Starliner in this capacity.

## Does NASA Require Starliner?

The question of whether NASA genuinely requires Starliner is intricate. On one side, NASA has repeatedly voiced support for Boeing and the Starliner program. Maintaining a second crew transport option provides redundancy and fosters competition, which can be advantageous for NASA’s long-term objectives. Furthermore, NASA is looking towards the 2030s, planning to support one or more private space stations in low-Earth orbit. In this scenario, having various providers, including Boeing, could prove beneficial.

Conversely, the timeline for Starliner is becoming increasingly stretched. The spacecraft is not expected to undertake its next human mission before 2026, thus limiting its operational lifespan as the ISS approaches retirement. This situation raises doubts about the value of investment in Starliner, especially given that SpaceX’s Crew Dragon has established itself as a reliable and cost-efficient alternative.

## The Path Ahead

Currently, Boeing is adhering to a standard post-flight protocol, which consists of joint sessions with NASA to assess the mission and deliberate on possible rectifications. While this procedure is customary, it fails to offer much insight into Starliner’s long-term trajectory. Much will hinge on Boeing’s internal assessment and NASA’s decision regarding ongoing support for the program.

In the interim, Boeing’s reticence is quite telling. The company stands undeniably at a critical juncture, and the choices made in the upcoming months will dictate whether Starliner continues to play a role in NASA’s plans.
